Pneumatic actuators have been widely utilized in various fields because of their advantages of low cost, safety, and high compliance. However, pneumatic systems need many air supply lines from a compressor, control lines from a controller, and power supply lines, making them complicated and large. This paper proposes a new operational method reducing the number of control lines and power supply lines in pneumatic systems. It needs two key components; Multiplex Pneumatic Actuator Drive (MPAD) and Local Power Supply (LPS) for each local module. MPAD utilizes acoustic communication between the oscillator nearby the compressor and receivers nearby each pneumatic actuators in air supply. LPS generates electric power utilizing compressed air from the compressor and supplies generated power for each local module including the pneumatic actuator. The prototype module is operated by generated power from LPS, and the pneumatic actuator 10 meters away from the oscillator is controlled by acoustic communication. Experimental results shows practicability saving control lines and power supply lines for pneumatic systems.

In this study, a torsional transducer type ultrasonic motor which realizes the continuous rotation and the positioning of the angle in cryogenic temperature has been fabricated and evaluated. In the cryogenic temperature environment, the performance of the transducer falls. In order to drive the motor at cryogenic temperature, the torsional transducer is designed to generate the resonant stick-slip drive. The transducer can perform the resonant stick-slip drive by combining the first and the second vibration mode. The ultrasonic motor using the transducer was evaluated. The rotation speed and the starting torque are 111rpm and 0.75mNm at 4.5K. Moreover, a velocity control became possible in the low-speed range below 1.0rad/s by using a burst waveform.

Pneumatic actuators can achieve compliance and flexibility easily. For the above-mentioned reasons, pneumatic actuators are used in widely fields of medical treatments and industries. However the pneumatic control vale that can control air flow rate smoothly is large scale weigh. The purpose of this study is development of the new flow control valve using torsional vibration. This valve can control air flow continuously and drive by power saving. In this report, firstly we show basic mechanism of the valve and expound the advantage to drive by low power. Next we designed the prototype of this valve using FEM. Finally, we confirmed the principle of the valve.

The purpose of this study is development of the flow control valve which is small in size, lightweight and can control air flow proportionally. In this study, we thought about a condition that makes flow rate proportional to applied voltage taking the vibration property of orifice plate into consideration. To verify whether the condition is appropriate to flow control valve using particle excitation, a prototype using Langevin type transducer structure that aims at application to proportional valve has been designed by using finite element method and made. And we have evaluated the vibration property and flow rate of the prototype.

Pneumatic actuators have been widely utilized in various fields and have the important role for operating production facilities in plants with their advantages of light weight, low cost, safety, and high compliance. However, driving them needs not only the air supply line from compressor but also many electrical lines from valve controller, making the pneumatic drive system complicated. In this paper, we propose a new pneumatic control system using acoustic communication in an air supply line. This system needs two technical challenges; acoustic operating system and power supply device for each local module. This system realizes simple pneumatic drive system without electrical lines. This prototype system works very well to show the great potential of this proposed system. It controls successfully three pneumatic cylinders independently which are connected with an air supply line of 10[m] in length.

In this study, an ultrasonic motor for a solid-state high resolution nuclear magnetic resonance (NMR) spectrometer has been fabricated and evaluated. In solid-state NMR analysis, it is necessary to rotate samples at a high speed and a high preciseness. The motor are composed of non-magnetic materials. The motor consists of two sector shaped vibrators. The diameter and the height of a probe unit including a sample case and the motor are 31 mm and 50 mm. The unit was unaffected by the magnetic field. The rotation speed was 1200 rpm when the magnetic flux density was 9.4T. Additionally, we have successfully obtained a solid-state NMR analysis of glycine. From this result, the motor can be applied to sample rotation of solid state NMR spectrometer.

A transducer for an ultrasonic motor for cryogenic temperature environment was fabricated. In the environment, a thermal stress is generated on the transducer. The motor is composed of a bolt-clamped Langevin-type transducer (BLT) and a rotor. To reduce the influence by thermal stress shift and to have high vibration velocity, a constituent material of the BLT is modified. The body parts of the BLT was made of SUS304 and the bolt of the BLT was made of titanium. We have evaluated the relationship between vibration velocity and the thermal stress. We have succeeded in reducing the thermal stress under the temperature condition from 4.5K to 293K.

In this research, a micro sensor which can detect cavitation in a microchannel has been fabricated by using piezoelectric polymer thin film. P(VDF/TrFE) was used as the sensor material. We have applied integration by using the photolithography process to miniaturize sensors. We have succeeded in fabricating the micro-sensor whose thickness is 158μm. We have also succeeded in receiving waveform in the high frequency range. Thus the sensor would detect cavitation by using frequency analysis of bubbles collapse sound.

Cryogenic condition has been used for scientific measurements and there are increasing demands for industrial regions. Additionally, there is a demand for actuators which can be driven in the ultralow temperature condition. In such temperature condition, although piezoelectric materials have low piezoelectricity, ultrasonic motors have been realized by using bolt-clamped type Langevin type transducer. In this paper, two materials, stainless and titanium has been used for transducer. The relationship between optimized clamping torque values and temperature has been examined experimentally.

Cryogenic temperature is very low temperature under 20K. The goal of this research is to realize an ultrasonic motor which can be used in this cryogenic temperature. When the temperature decreases from room temperature to an ultralow temperature, a thermal stress is generated. By this stress, the ultrasonic motor breaks down or the performance is decreased. The purpose of this research is to reduce the thermal stress in the ultrasonic motor. A bolt-clamped Langevin-type transducer (BLT) is used as a transducer for the ultrasonic motor. The BLT is mainly made of invar (Fe Ni alloy). Invar has a coefficient of thermal expansion near to that of lead magnesium niobate-lead titanate (PMN-PT) single crystal. We have evaluated the thermal stress in the BLT from 300K to 4.5K. Additionally, the thermal stress in the BLT made of invar was about 50% of that in the BLT made of SUS304.
