We develop thin electromagnetic motors driven without reduction mechanism, and mobile power source for pneumatic actuators. We use ultrasonic, electromagnetic or fluid phenomenon for these requests. </p> </div> <h4>Research Introduction</h4> <h5>Development of ultrasonic motor for ultralow temperature condition</h5> <div class="typeB"> <div class="left"> <p> &nbsp;&nbsp;Ultralow temperature environment provide important measuring condition in advanced scientific research area. There are demands for actuators that can drive in ultralow temperature conditions.<br /> &nbsp;&nbsp;We have succeeded in driving the motor at ultralow temperature under the low temperature condition. </div> <div class="right"> <p><img src="../../img/extreme/uiNO)n000.jpg" alt="uiNO)n000" width="370" height="278" /></p> </div> </div> <HR size="2" width="100%" align="center" color=""> <h5>Ultarasonic motor for solid-state nuclear magnetic resonance</h5> <div class="typeB"> <div class="left"> <p><img src="../../img/extreme/7_x4X000.jpg" alt="7_x4X000" width="370" height="220" /></p> </div> <div class="right"> <p> &nbsp;&nbsp;In this study, we aim at applying an ultrasonic motor to a sample rotating mechanism for the high resolution solid state nuclear magnetic resonance (NMR) spectroscopy. An ultrasonic motor can be driven in various environments. <br /> &nbsp;&nbsp;The motor was used for the solid-state NMR spectroscopy measurement under the high intense magnetic field of 7 T. The NMR signal of sample has been successfully obtained. </p> </div> </div> <HR size="2" width="100%" align="center" color=""> <h5>Concave type micro ultrasonic transducer using PZT film deposited by the hydrothermal</h5> <div class="typeB"> <div class="left"> <p> &nbsp;&nbsp;Since the hydrothermal method is a reaction in an aqueous solution, the piezoelectric film can be deposited on a substrate having a three-dimensional shape. In this reserch, a concave type micro ultrasonic transducer was fabricated by using the hydrothermal method. In this reserch, a concave type micro ultrasonic transducer was fabricated by using the hydrothermal method.<br /> &nbsp;&nbsp;The focused ultrasonic wave generated by this transducer is effective for the manipulation of fine particles in a micro region. </div> <div class="right"> <p><img src="../../img/micro_nano/2017_4lqTbl_l[.jpg" alt="4lqTbl" width="250" height="142" /></p> </div> </div> </div> </div><!-- other_page B}00 --> <div id="foot_up"></div> </div><!-- contents B}00 --> </div> </body> </html>
