Title: Piezoelectric electroacoustic converter unit
Inventor: YAMAZAKI TSUNEO
IPC: H04R17/00
Filed: 1979-09-26
Abstract: PURPOSE:To make it possible to obtain a piezoelectric electroacoustic converter of high power by employing a multilayered structure by providing piezoelectric films, differing in polarity, by turns and also to make it possible to form the thin and compact unit on a sound generator in a random shape by providing films in the sputtering method. CONSTITUTION:Between electrodes 1 and 2, piezoelectric films 3 and 4 differing in polarity are stacked by turns. Sound generator 5 is vibrated by piezoelectric films 3 and 4 to generate sound pressure. As a voltage is applied between electrodes 1 and 2 via lead wires 6 and 7, piezoelectric films 3 and 4 differing in polarity are applied with electric fields in the opposite directions mutually, so that generated strains will be equal in polarity. For this purpose, piezoelectric films 3 and 4 are stacked into a random lamination, so that large driving force can be obtained. Further, zinc oxide films used as piezoelectric films are oriented in the high-frequency magnetron sputtering method in a mixture atmosphere of argon and oxygen.

IPC: G01N11/14
Filed: 1985-06-10
Abstract: PURPOSE:To enable automatic adjustment of a desired resistance value or slump value, by detecting the resistance value of a hydraulic hardening material during the kneading. CONSTITUTION:A torque detector 16 detects a torque transmitted to a mixer A from a primemotor 15 and an arithmetic unit 18 calculates a slump value of a hydraulic hardening material during the kneading on a signal from the detector 16 through a converter 17.

Abstract: PURPOSE: To minimize the sectional area of a metallic connection part by forming part of the metallic connection part into a large sectional shape, holding a 1st predetermined minimum distance between the metallic connection part and a gate layer, and also holding a 2nd predetermined distance between the metallic connection part and one edge of a metallic connection line. CONSTITUTION: A metallic connection part 22A is formed such that the corners of connection parts facing edges of diagonal metallic lines 30 are cut obliquely. Therefore, a minimum distance (x) between the metallic connection pat 22A and a polysilicon gate 23 and a minimum distance (v) between the metallic connection part 22A and the edges of the metal lines 30 are held, the sectional area of the metal connection part 22A becomes a maximum, and the ON- resistance of an MOSFET becomes minimum. Thus, the corners of the metallic connection part 22A are cut obliquely to eliminate the need for expanding the width of the metal lines 30. Consequently, the distance between cells is held at a desired value and when the metal lines 30 are increased in width, the distance between the cells increases. Therefore, the ON-resistance of the MOSFET becomes minimum.
