2016 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IUS) 2016

Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE

Pneumatic actuators are widely used because they are lightweight and inexpensive. However, highly controllable devices for pneumatic actuators generally have large volume and low response and are heavy. We have developed the flow control valves that have highly controllable using PZT elements. These control valves can downsize the control valve with high response. Using a PZT transducer, we introduced a new mechanism of the control valve for stable continuous flow rate. In this report, we proposed a new mechanism to realize stable continuous flow with a PZT transducer. We designed prototype using a bolt-clamped Langevin transducer (BLT) and show the characteristics of the valve.

2016 IEEE INTERNATIONAL ULTRASONICS SYMPOSIUM (IUS) 2016

Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE

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 modes. The ultrasonic motor using the transducer was evaluated. The rotation speed and the starting torque are 111 rpm and 0.75 mNm at 4.5 K.

IEEJ Transactions on Sensors and Micromachines 136 ( 8 ) 348 - 356 2016

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：Institute of Electrical Engineers of Japan

In this study, we have fabricated a droplet manipulation device which has a microchannel oscillated by piezoelectric actuator. This device can manipulate droplets by producing a pressure distribution of a standing acoustic field caused by ultrasonic vibration in the microchannel. The manipulated droplet's size has been estimated from the relationship between acoustic force and viscous force. The device has been designed by using a finite element method analysis. Fabricated device has been evaluated by observing droplets in manipulation experiment and measuring a manipulated droplet's distribution. When n-dodecane was used as dispersed phase, this device can manipulate a droplet whose diameter is larger than 20μm when the applied voltage and the driving frequency were 80Vp-p and 2.25MHz. When Silicone oil was used as dispersed phase, the manipulated droplets diameter was larger than 15μm. From these results, we have indicated that the microchannel device can manipulate droplets by using ultrasonic vibration.

Mohamed Najib Ribuan, Shuichi Wakimoto, Koichi Suzumori, Takefumi Kanda

International Journal of Automation Technology 10 ( 4 ) 494 - 502 2016

Language：English Publishing type：Research paper (scientific journal) Publisher：Fuji Technology Press

This manuscript explains the employment of flexible actuators to act as a soft robot and transporting agent to assist medical X-ray examinations. Although soft robots from silicone material can be transparence and a human compliance used as medical assistive devices, soft robots have some problems: they tend to be sluggish, have long and imprecise gait trajectories, and need their control parameters to be adjusted for motion diversion. A soft robot with omnidirectional locomotion has been created, one that has a combination of pneumatic rubber legs that form a soft robot platform and an associated hardware setup. Tests have confirmed its omnidirectional locomotion ability
it has a maximum speed of 6.90 mm/s in forward locomotion and a maximum payload of 70 g. These features indicate that the robot can be used as a medical assistive device for fluoroscopy examinations.

Proceedings of JSPE Semestrial Meeting 2015 887 - 888 2015

Language：Japanese Publisher：The Japan Society for Precision Engineering

In many fields, such as electronic material and medicine, it is an important subject to generate small and monodispersity droplets of various liquids. In this study, to generate micro droplets for a chemical manufacturing process, we have designed and fabricated a system using a bolt-clamped Langevin-type transducer and the micropore plate in order to generate micro droplets. First, we observed the range of applied pressure to generate uniform droplets. As a result, the condition depends on the kinematic viscosity of continuous phase. Next, we investigated the droplet generation condition when the droplets are in monodisperse, when the droplets are generated in the flowing ambient liquid.

Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE

The aim of this paper is to realize a new sample spinning unit for a solid-state nuclear magnetic resonance (NMR). In the solid-state NMR analysis, a sample spinning in high magnetic field is an important function. We have designed and fabricated the sample spinning unit using a low-profile ultrasonic motor for high magnetic field. The unit could be driven in high magnetic flux at 9.4 T. Soli-state NMR analysis of glycine was measured using the unit. We have succeeded in applying the ultrasonic motor for solid-state NMR analysis.

Journal of Robotics and Mechatronics 25 ( 2 ) 384 - 391 2013

Language：English Publishing type：Research paper (scientific journal) Publisher：Fuji Technology Press

This paper presents the design, fabrication process, and evaluation of an ultrasonic motor for sample spinning in a high magnetic field of solid-state Nuclear Magnetic Resonance (NMR). To decrease effects of the magnetic field on rotation, all motor components are made of materials that have low magnetic permeability. The motor, including the sample casing, is a maximum 31 mm in diameter and 50 mm high. The motor has two sector-shaped piezoelectric transducers. One transducer generates two different vibration modes, longitudinal and flexural, when two sinusoidal voltages are applied to transducers. To confirm that transducers can be driven in a high magnetic field, the effect of the magnetic field on the transducer was evaluated. The motor was driven at a frequency of 329.0 kHz. The maximum rotation speed and starting torque were 1.50 × 103 rpm and 26 μ Nm when applied voltage was 40 Vp-p. The rotation speed, controlled by a proportional-integral control system, was 1.20 × 103 rpm in a 7.0-T magnetic field. The motor was also applied to the sample spinning system of a high-resolution NMR spectrometer. We succeeded in obtaining 1 H-NMR signals of H2 O. The motor can therefore be used for a sample spinning system in a high magnetic field.

IEEJ Transactions on Sensors and Micromachines 133 ( 8 ) 330 - 336 2013

Language：English Publishing type：Research paper (scientific journal)

Light-driven actuators result in the miniaturization of micro-devices because such actuators can be driven by a non-contact energy supply. PLZT is a ferroelectric material that exhibits a photostrictive effect. We have succeeded in driving a photoresponse actuator by using the PLZT film. The PLZT film was deposited on a titanium substrate by using the hydrothermal method. The PLZT film was evaluated by x-ray diffraction and piezoelectricity. The actuator has a simple structure in which an indium tin oxide (ITO) transparent electrode is deposited on the surface of the PLZT film. The actuator is driven by the ultraviolet (UV) light. To confirm the driven phenomenon, the photoresponse drive was evaluated by measuring the displacement, electric current and surface temperature. As an example of a light-driven application using the PLZT film actuator, we also fabricated and evaluated a light-driven valve. We have succeeded in changing the flow rate when the intensity of the UV light increased. © 2013 The Institute of Electrical Engineers of Japan.

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE SA

This paper reports on generating micro and uniform droplets in various viscosity liquids by using a micropore plate oscillated by an ultrasonic torsional transducer. When the micropore plate was not oscillated, generated droplet diameter was not stable. On the other hand, when the micropore plate was oscillated, generated droplets became small and uniform by ruffling the liquid column surface. Droplets were generated experimentally in the air by using pure water and silicone oil of various viscosities and then evaluated. We have designed the ultrasonic torsional transducer and a droplet generation device to apply a high pressure for the use of higher viscosity liquids. We have succeeded in generating droplets by using pure water when the ultrasonic torsional transducer and the micropore plate that had an 18-mu m-diameter micropore were used. The average diameter of droplets was 30.0 mu m and the standard deviation was 0.98. We have also succeeded in generating 50-cSt silicone oil droplets by using the droplet generation device and the micropore plate that had the 50-mu m-diameter micropore. The average diameter of droplets was 98.0 mu m and the standard deviation was 0.76. (C) 2012 Elsevier B.V. All rights reserved.

SENSORS AND ACTUATORS A-PHYSICAL 184 134 - 140 2012.9

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER SCIENCE SA

In this study, a small ultrasonic motor driven under cryogenic temperature conditions has been fabricated and evaluated.
Since transducer performance generally decreases at cryogenic temperatures, we designed and fabricated a bolt-clamped Langevin-type transducer for operation at cryogenic temperature. We simulated the influence of thermal stress on the transducer. The results from simulation were used to design the transducer, and it was then used to fabricate an ultrasonic motor for cryogenic temperature. The maximum diameter and the height of the motor are 30 mm and 38.7 mm.
To enable the motor to be driven at cryogenic temperature, we evaluated the relationship between the contact pre-load and the lowest rotatable temperature. The motor's driving performance was evaluated at both room temperature and cryogenic temperatures. In a 4.5 K helium gas ambient, the rotation speed and starting torque were 133 rpm and 0.03 mu N m when the applied voltage was 50 Vp-p. (C) 2012 Elsevier B.V. All rights reserved.

Daisuke Yamaguchi, Takefumi Kanda, Koichi Suzumori, Masataka Kuroda, Dai Takeda

JAPANESE JOURNAL OF APPLIED PHYSICS 51 ( 7 ) 07GE09-1-07GE09-6 2012.7

Language：English Publishing type：Research paper (scientific journal) Publisher：JAPAN SOC APPLIED PHYSICS

In this study, an ultrasonic motor for use at ultralow temperatures has been fabricated and evaluated. The motor has a bolt-clamped Langevin-type transducer using lead magnesium niobate-lead titanate (PMN-PT) single crystal. The transducer is proposed as an oscillator for use at ultralow temperatures by simulation of the thermal stress and evaluation of the pre-load. The thermal effect of the transducer was evaluated when the temperature was changed. As a result, the pre-load of the transducer was concluded to be affected by thermal stress. In addition, the ultrasonic motor using the transducer was fabricated and evaluated. By adjusting the contact pre-load between the rotor and the transducer, the motor has successfully rotated at an ultralow temperature. The rotation speed was 144 rpm at 4.4 K when the applied voltage was 150 Vp-p. This rotation speed is larger than that of previous same size actuators that can be used at ultralow temperatures.

2012 19TH INTERNATIONAL CONFERENCE MECHATRONICS AND MACHINE VISION IN PRACTICE (M2VIP) 501 - 506 2012

Language：English Publishing type：Research paper (international conference proceedings) Publisher：IEEE

In this paper, PZT film has been deposited on Ti substrate by using a hydrothermal method. The hydrothermal reaction solution was stirred by 2 types of methods. One mixing method was a rotation mixing method and the other was an ultrasonic vibration mixing method. Bimorph actuators were fabricated and evaluated with displacement measurement. Because of holding the autoclave, the ultrasonic vibration mixing device was less of a load to the substrate. Therefore, micropositioning stage has been fabricated on a comparatively large and high-aspect ratio titanium structure by using the ultrasonic vibration mixing device. The hydrothermal method can easily deposit on the three-dimensional substrate. Thus, we have deposited PZT film on a hemispherical shape Ti substrate and fabricated an ultrasonic transducer by using the rotation mixing device. The ultrasonic transducer was evaluated by under water experiment.
