摘要： An ultrasonic motor piezoelectric actuator element uses a primary longitudinal mode and a secondary bending mode and includes a stacked piezoelectric element in which piezoelectric layers and electrode layers are stacked alternately in such a manner that the electrode layers divide the piezoelectric layers into two approximately equal portions. A piezoelectric inactive region is formed from the surface portion to the center portion in the thickness direction of the stacked piezoelectric element. The migration resistance of the piezoelectric actuator element is improved while suppressing a decrease in displacement so that a short circuit can be prevented and portions generating heat during alternating polarization can be dispersed, whereby reliability is increased. Moreover, the amount of electrode material used can be reduced, whereby cost can be reduced.

摘要： A method employed in a prior art arm-worn blood pressure monitor to measure the height position of the heart has been an indirect method that merely estimates the position of the heart, and therefore has had the problems that the measurement accuracy and the reliability of the measurement are low, and that the measuring position is awkward and it is difficult to achieve correct position alignment. An arm-worn blood pressure monitor includes a cuff, a microwave transmitting unit for radiating a microwave onto a human subject, a microwave receiving unit for receiving a reflected wave Doppler-shifted relative to the radiated microwave due to a heartbeat of the subject, and a correct position detector for detecting, based on the reflected wave, whether the cuff worn around an arm of the subject is located in a correct position relative to the position of the heart of the subject.

摘要： There is provided a method for manufacturing a piezoelectric actuator where the planar shape is adjusted by subjecting the piezoelectric body layer located on one of the outer surfaces in the two or more piezoelectric body layers to a polarization treatment to control remnant polarization of the piezoelectric body layer. The piezoelectric actuator is used as a drive portion of a piezoelectric drive type variable capacitor. The variable capacitor has high mechanical strength and excellent reliability for a long period of time. The relation between the displacement amount of the piezoelectric actuator and the capacity of the capacitor is stable, and the variable capacity is wide.

摘要： A piezoelectric/electrostrictive element having a double-layer structure in which a lower layer electrode film, a lower layer piezoelectric/electrostrictive film, an inner layer electrode film, an upper layer piezoelectric/electrostrictive film and an upper layer electrode film are laminated in this order on a thin portion of a substrate. In the piezoelectric/electrostrictive element, a driving signal is applied between an outer layer electrode film and the inner layer electrode film, whereby the thin portion and a laminate can be subjected to bending vibration. The piezoelectric/electrostrictive film has film thickness distribution in which a film thickness becomes larger in a continuous manner from a center portion of a bending vibration region which is an antinode of a bending first mode toward an edge portion of the bending vibration region which is a node of the bending first mode, along a short side direction of the bending vibration region.
