I investigated the distributed external acoustic impedance sensing based on correlation-domain technique for the oil inspection of underground and cancer detection. First, I measured acoustic impedance dependence of linewidth of guided-acoustic wave Brillouin scattering (GAWBS). Second, I observed the enhanced GAWBS in highly nonlinear optical fibers using pump-probe technique for signal-to-noise ratio improvement. Third, I demonstrated the distributed temperature/acoustic impedance sensing based on GAWBS using Brillouin optical correlation-domain technique. Fourth, I observed GAWBS in special optical fibers. Fifth, I proposed the method for long-term localization of GAWBS in optical fiber.

In this study, control of liquid crystal molecular orientation using ultrasound was investigated. Ultrasound liquid crystal devices were fabricated and the effects of ultrasound vibration on the molecular orientation were evaluated experimentally. The molecular orientation of liquid crystals could be controlled spacially and temporally by the input signals to the devices. Variable-focus optical lenses using this technique were also developed. The molecular orientation of liquid crystal in the lens could be controlled by the input voltage and the focus point of the lens could be successfully controlled.

Ultrasonic motor is an actuator driven by high frequency vibration through friction force, and provides quick response and high torque-to-weight ratio. But its application has been restricted to special areas such as auto-focusing in camera and other precise positioning systems because its efficiency and life were limited. To overcome this problem, this study introduced lubricant in the friction interface between the rotor and vibrator, and then succeeded in developing efficient and durable ultrasonic motor. We carefully researched on the conditions of preload and vibration amplitude. The efficiency has been improved from 40% to 70% in hybrid transducer-type ultrasonic motors. Our experiments also proved that the life was successfully extended, and the operation stability was improved. In addition, the effects of the lubricant characteristics and the materials of contacting surfaces were experimentally investigated.

To avoid contamination and increase processing speed, a non-contact technology for manipulating droplets will be required in production process of chemical materials and development of new materials. In this study, we proposed and developed systems for various kinds of processing such as transport, mixing, dispensing, and analysis of liquid sample without contact.
For non-contact mixing of two drops of different liquid, we proposed to utilize two orthogonal ultrasonic standing wave fields. The method was proved with the experiments at several 10 kHz. To eject single droplet from a container, the conditions of the intensity and time duration of 1-MHz burst focused waves were examined. We demonstrated a coating process for a small object levitated at the nodal point of ultrasonic standing waves. A vibration system stabilized with a feedback oscillator was developed for the coating processing.

For the application in pharmaceutical and high-quality chemical industries, totally non-contact transport of droplet is highly demanded. Techniques for non-contact mixing and dispensing are also required. We have succeeded in the noncontact linear transport of ethanol droplets of 1.5 mm in diameter using a semi cylindrical acoustic waveguide. The waveguide was composed of a bending vibration plate and a semi cylindrical reflector, and a traveling wave acoustic field was excited in the waveguide. The droplet was levitated due to the radiation force of the acoustic field, and then, pushed in horizontal direction because of acoustic streaming. The transportation distance was 65mm and the terminal velocity was over 2 m/s.
We also succeed in noncontact mixing of two droplets, and dispensing a droplet through a hole installed in the reflector plate.

This study presents the design of multi-degree-of-freedom ultrasonic actuator for the miniaturization and for the array arrangement on a substrate. Both cylinder and plate types were considered as suitable configurations for the array structure of the ultrasonic actuators.
For the cylinder type actuator, a simple configuration with a cylindrical stator and a piezoelectric element was suggested. Then, the ratio of the diameter against the height of the cylinder was determined as 0.5 for the resonance frequency matching using finite element analysis (FEN), and the rotations around all the axes were obtained using the single actuator of 14mm in height and 7.0mm in diameter. In the arrayed configuration, it was found that there was a vibration coupling among the element actuators. To suppress the unnecessary vibration, trench and barrier structures were considered using FEA. It was became clear that these configurations were not effective in the cylinder type. The structure of the cylinder-type actuator was appropriate for the synchronized excitation of the arrayed element actuators, and two-directional motion of 93° and the minimum step of 0.19μm of the plate on the actuators as a two-dimensional stage were prototyped.
For the plate type, a simple configuration using a cylindrical stator and a piezoelectric element with two-layered substrate was proposed. the unnecessary vibration in the plate type actuator array decreased more than in the cylinder type because of its structural feature, and effects of thin glue layer between the actuator and the substrate. Being based on the plate type, a 4x4 array was designed and fabricated. Using this model, a two-dimensional sliding table was prototyped. Wiring pattern for feeding electrical power to each element in a large-sized array actuator was studied.

We investigated the relationship between comfortable sound properties and damping characteristics of organic hybrid.
In order to obtain organic hybrid with higher damping performance, we studied on factors determining damping performance of organic hybrid and influence on an addition of inorganic fillers such as carbon and silica particles and carbon fiber.
It was found damping performance is influenced by amount, intensity and structure of interaction between polymer and low molecule, besides an energy loss by polymer and low molecule themselves.
Addition of inorganic filler improved damping performance, resulting from high energy loss at the interface between filler and matrix. The increase in damping performance by addition of inorganic filler decreased with increasing content of low molecule. This is because an applied mechanical energy becomes difficult to transmit to the filler surface by fluidity of low molecule at higher content of low molecule. However, further addition of inorganic filler recovered transmission of mechanical energy to a filler surface, resulting in an increase in damping performance.
For investigation of comfortable sound properties, we estimated a transfer function between input signal and output sound of a speaker lined with and without organic hybrid. By lining with organic hybrid, we observed a change in a transfer function at certain frequency. We supposed this change in a transfer function influenced on comfortable sound properties.

A new method to investigate the conditions of concrete structure and to search land mines using sound property has been proposed in this study. The surface conditions of the specimen is measured in term of the surface acoustic impedance without contact. The following three subjects were mainly investigated:
(1) The relationships between the surface condition and the acoustic impedance
(2) The formulation of the acoustic impedance and the surface condition with the sound pressure at two points
(3) A novel method to measure the sound field distribution without disturbing the field to be measured.
We demonstrated the experiments of the surface acoustic impedance measurements for a bottle embedded in a shallow land. The possibility of finding the embedded object through the sound impedance measurements was confirmed as the result of the experiment. The equations denoting the relationship between the surface condition and the acoustic impedance were deduced. An optical method to measure the sound field distribution in a pipe is newly invented in this study. A combination of a low-coherent light source and an adjustable optical path length enabled us the measurements of sound field with spatial resolution in the longitudinal direction. In conclusion, the basic theory and the instrumentation have been founded for the purpose in this study.

Many studies about structural intensity (SI) measurement, which is useful to know transmission paths of the vibration energy in a body, have been reported until now. Most of the works, however, have been done only for thin bodies, such as beams or plates because of the difficulty in measuring interior vibration distribution in thick structures. In this research, we propose a new SI measurement method applicable to thick bodies. The entire vibration distribution in the structure is calculated by dynamic analysis of finite element method (FEM) from the partial surface vibration data if the density, the sound velocity, sizes of a body under study and the locations of excitation and absorption are given apriori. The entire SI distribution can be estimated using the results. Based on this method, we have successfully carried several SI measurements for thick vibrating bodies. The merits of this method are as follows: (1) Only surface vibration data of the structure is needed to estimate the entire SI distribution. (2) It is applicable for arbitrary 3-D structures if the conditions mentioned above are satisfied apriori. In the research, the influence of the measurement error and the required number of the measurement data are also investigated.

This study was focused on the improvements of an ultrasonic stepping motor for its practical use. In this motor, a stepping motion is realized by shifting spatially the standing vibrations of a ring/disk stator.
1) To support the stator firmly, a bending vibration mode of a disk with a nodal circle was introduced. An appropriate stator configuration was designed by Finite-Element-Method and made. We succeeded in fix the stator without reduction in vibration characteristics.
2) An experimental investigation on the contact mechanism at the rotor/stator interface revealed that the accuracy of step position becomes high when the width of contact region is designed at a quarter wavelength of the stator vibration.
3) A motor with 4.5 degree-step was designed and made being based on these new knowledge.
4) A high speed operation algorithm for accurate positioning was developed, where a large step high spped coarse positioning and a small step fine positioning were used complementarily.
It was clarified that the accuracy of the electrode pattern and the dimensions of the stator should be improved for much higher precision. A design for higher vibration amplitude is also important for larger mechanical output
5) A principle of linear stepping motor was also proposed. A reversible stepping motion of 10 steps for 50 mm span was realized by exciting several bending vibration of a bar with different order.

The Purpose of this research is to establish the practical technique of structural intensity measurement. In this study, the k-space signal processing and ultrasonic Doppler vibrometer array for structural intensity measurement have been proposed. We have obtained the following results.
1.K-space method The derivation of structural intensity defined as vibration energy flow in solid structure contains the higher order spatial derivatives of displacement for flexural vibration. This calculation has a large effect on the measurement accuracy. In the proposed method, there are some merits that the spatial derivatives can be estimated only by the simple arithmetic in k-space using spatial Fourier transformation and that vibration noise can be reduced by k-space filtering. In order to avoid the loading effect on the specimen, a laser Doppler vibrometer was used which is one of the most promising candidates. We obtained the important result that the cutoff wave number for k-space filtering should be one and a half of the wave number of the measured vibration to minimize the influence of error in the measured data. This result was confirmed by the experiments for a beam and 2-dimensional plate.
2.Ultrasonic Doppler transducer array We proposed a new probe for structural intensity measurement using ultrasonic Doppler method. This probe is suitable to make a large array system, since the ultrasonic system is to easy handle and cheaper than the optical one and has no loading effect to specimens. The array probes for 1-dimensional and 2-dimensional measurements were made. The usable range of these array is 3 mm/s-1.0m/s at vibration frequency 1 kHz. The validity of the ultrasonic transducer array using Doppler effect is confirmed experimentally by the 1-dimensional and 2-dimensional structural intensity measurements.

本研究の目的は、効率や寿命、振動系設計の複雑さのような従来の超音波モータの欠点を根本的に解決するために、研究代表者が提案する電気粘性流体を利用した新しい超音波モータの基礎的な特性を調べ、設計法について検討することであった。本モータでは従来の超音波モータにおける振動による摩擦力制御にかわって、印加電界によって粘性が変化する流体(電気粘性流体、ERF)をロータ・ステ-タ駆動面に導入しており、従来のようにロータとステ-タが直接接触しないので、効率や寿命を改善できる可能性がある。また、振動成分は駆動力源となるもの単一でよく、振動系の設計の自由度が増大する。
ERFによる「ねじり振動-ロータ回転」変換機構の基礎的性質を検討するため、電磁式ねじり振動子とロータ、ERFからなるモータを試作して、その特性を測定し、以下のような結果を得た。
1)ねじり振動をロータ回転に変換することに成功した
2)ねじり振動とERF印加交番電界の位相差を変化することで回転方向を制御可能である
3)ねじり振動速度の5割程度のロータ回転速度が実現できた
さらに、本モータの最適な動作点を検討するために、電気等価回路モデルによる数値解析を行った。その結果、
1)駆動周波数が高いほどすぐれた特性が得られる
2)理想的にはねじり振動速度と同程度のロータ回転速度が得られるはずである
3)以上を実現するためには高速なERFの開発が必要である
4)既存のERFで従来の電磁型モータと同程度の出力トルクが得られるはずである

We have proposed a novel scheme of self-aliging optical components and single mode fiber arrays, which is composed of an array put-in microconnectors. We fabricated a put-in microconnector consisting of an etched single mode lens jack and an fiber plug formed on a planar microlens substrate by a self-aligning technique. Some optical coupling characteristics without precise mechanical alignment were investigated. In this study, we aim at the realization of multifunction optical circuits using this put-in microconnector array. Therefore, the realization of low loss fiber connector, the establishment of evaluation method of self-aligning connects, the design and fundamental study of optical connect module are the objectives of this study.
We tried to connect self-alignment between a single mode fiber and a planar microlens. The loss of connection was less than 5dB at the wavelength of 633nm. Besides, it was found that the connection loss by introducing of the lens-jack and fiber-plug is very small. We established the evaluation method of optical self-alignment by assuming a planar microlens to a thin lens. We also estimated the loss of each module. If the fiber is connected to the semiconductor laser diode without the error of connection angle and position, the distance between the semiconductor laser diode and the planar microlens is about 15mum, the distance between the planar microlens and the fiber is about 150mum for the tolerance of 1dB.It is found that we cannot omit the influence of spherical aberration of planar microlens, by this analysis. We found that the put-in micro connector is suitable structure for decreasing this spherical aberration. Thus, it will be a key technology for simple optical couplers for the advanced parallel optical fiber communications.

4)理論的に、曲率と感度の関係が明らかになった、
一方、
5)曲率部の寄生振動が特性を制限する事実がわかり、
6)寄生振動を抑圧する構造を開発する必要があるという課題が残った。
