Title: Piezoelectric actuator
Inventor: SENDA YUKIO
IPC: H01L41/09
Filed: 1986-09-29
Abstract: PURPOSE:To make it possible to apply a high electric field and to obtain a large amount of displacement and a large yielding force, by laminating piezoelectric plates in the direction of thickness, forming a longitudinal-effect type piezoelectric element, and providing a means which constraines the elongation of the element on one side of the element in the longitudinal direction. CONSTITUTION:Piezoelectric ceramic plates 2 are laminated so that surfaces are aligned in the direction of thickness. Thus a longitudinal-effect type piezoelectric element 1 is formed. A metal plate 11 is stuck to the side of the element 1 in the longitudinal direction with an insulating bonding agent such as epoxy resin to form an insulating layer 12. An electric field is applied in the same direction as the polarizing direction of the ceramic plates 2 through a power source 4 and electrodes 3. Then the element is elongated in the longitudinal direction. At this time, since one side surface is constrained with the metal plate 1, the entire body is bent in the arrow direction C. As a result of the bending, the large amount of displacement at the tip part and the large yielding constraining force are obtained as a piezoelectric actuator.

Title: Frame synchronization characteristic test circuit
Inventor: MUROI KIYOSHI
IPC: H04L7/08
Filed: 1986-09-30
Abstract: PURPOSE:To attain a high-speed operation and to simplify the constitution of the titled circuit by inserting a gate to supply/interrupt an input signal in the transmission line for the input signal, and controlling the supply/interruption of the input signal by using a test control signal to set whether or not the test is executed and step-out signal. CONSTITUTION:When a test control signal S8 is made to '1', the gate 6 is controlled with the step-out signal S3, and when the step-out signal S3 is '0', an input signal S5 to a frame synchronizing circuit 1 is cut off, while when the signal S3 is '1', an input signal S4 passes through the gate 6 and goes to an input signal S5 to the frame synchronizing signal 1. Since the time to start the retrieval of a frame pulse F coincides with the position of the frame pulse F itself, the average synchronization restoring time goes to zero, accordingly, a time T1 goes to the front restoration time and a time T2 the rear restoration time. In normal case when such a test is not executed, the test control signal S8 is made to '0', but is made to '1' in case of executing the test, thus, the frame synchronization characteristic can be tested. In such a way, the switching means can be constituted only with the gates 6 and 7.
