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 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.

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.

In many fields, such as electronic material, medicine and cosmetics production, it is an important proposition to generate small and uniform droplets of various liquids. In order to realize these droplets' generation, a bolt-clamped Langevin-type transducer and a micropore plate has been used. The purpose of this study is to fabricate a bolt-clamped Langevin-type transducer having small and simple structure in comparison with the previous one, and to generate droplets by using this device. First, by using a new fixation method, we have designed a bolt-clamped Langevin-type transducer whose structure is suitable for miniaturization. Next, we have generated and evaluated droplets in the air by using pure water. When the micro pore diameter, the applied air pressure and the resonance frequency were 50μm, 30kPa and 37kHz, the average diameter of pure water droplets and standard deviation of diameter were 96.1μm and 0.98, respectively.

The purpose of this research is the improvement of driving performance and the downsizing of a light driven SMA actuator. The actuator consists of a substrate, an optical waveguide and SMA wires. The drive part of the SMA actuator is 15 X 1 [mm]. In this paper, the SMA wires are glued on the substrate. As a result, the thickness of the SMA actuator was reduced from 0.5 mm to 0.2 mm. In addition, an absorption film was patterned on the substrate by a YVO4 laser. This is because the SMA actuator was heated effectively. The effect of the pattern was evaluated empirically.

This research aims to realize a flexible displacement detection sensor that can be attached on flexible soft bellows actuators. The sensor material is piezoelectric polymer: poly(vinylidene fluoride-trifluoroethylene) [P(VDF/TrFE)]. By adjusting temperature and applied voltage in the process of polarization, fabrication conditions were optimized. In addition, the piezoelectric polymer sensor was mounted to the actuator having a bellows structure. A flexible substrate was used as wiring in order to keep flexibility. The actuator is curved by using a negative pressure. As a result, we have confirmed the detection of actuator displacement by the sensor.
