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.

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.

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.
