Abstract: PURPOSE:To prevent breakdown of a strain detecting part and an electric wiring part and to improve durability and reliability by a construction wherein a support member positioned on the diaphragm surface side whereon a strain detecting part is formed is provided with a sheet member covering an introducing hole. CONSTITUTION:A sensor is constructed in such a manner that a strain detecting part 12 composed of strain gages and others is formed on one side of a thin-plate-shaped metallic diaphragm 9 and that the diaphragm 9 is supported by two support members 10 and 11 made to abut each other from the opposite sides. Besides, pressure medium introducing holes 10a and 11a are formed in the support members 10 and 11 respectively for two pressure receiving surfaces of the diaphragm 9, and, moreover, a sheet member 22 covering the hole 10a of the support member 10 positioned on the side whereon the strain detecting part 12 is formed is fitted to the opening part of the hole. Thereby the strain detecting part 12 and an electric wiring film can be made free completely from a state of contact with liquid. By forming a space wherein a pressure medium is present and a space wherein a part for signal lead-out and connection comprising an electric wiring and others is disposed, in complete separation from each other, protection of these components is made complete and, besides, the diaphragm can have a high durability to high pressure.

Abstract: PURPOSE:To suppress the fluctuation of the threshold voltage value of a gate, by adding acceptor impurities such as boron in gate polysilicon, doping phosphorus at the same time, and using movable ions such as alkali metal ions in a gate insulating film as a getter. CONSTITUTION:A polysilicon film 13 which is used as a gate electrode is deposited by a vapor growth method.

Filed: 1989-04-06
Abstract: PURPOSE:To accurately measure a rotational angular velocity without being affected by the characteristics of piezoelectric elements by connecting detection terminals for detecting the rotational angular speed to the input side of the piezoelectric element for driving. CONSTITUTION:Detection terminals 28a and 28b are connected to two input terminals of a differential circuit 30. This circuit 30 detects impedance variation between the piezoelectric elements 16a and 16b for driving as the potential difference between their electrodes 22a and 22b. Therefore, the rotational angular velocity of the vibration gyro 10 is known from the output of the circuit 30. This gyro 10 uses no detection dedicated piezoelectric element and the potential difference between the electrodes 22a and 22b of the elements 16a and 16b is detected to measure the rotational angular velocity. Therefore, even if the elements 16a - 16b have variance in characteristics, the rotational angular velocity can accurately be measured without being affected by the characteristics of the elements as a driving voltage is made command and stabilized.

Abstract: PURPOSE: To prevent the discoloration of a lead frame by rust, etc., caused over ageing while the lead frame is stored by plating a metallic part on the side face of a through section with a metal after an etching process and giving a rust preventing property to the metallic part on the side face of the through section exposed from a resist film. CONSTITUTION: After a through section is formed through a metallic material 1 in an etching process, the material 1 is temporarily removed from the manufacturing line of a lead frame. Then a plated-metal layer 3 is formed on the side face of the through section by plating the side face with a metal. Since the surface of the material 1 is coated with a resist film 2' after plating, the material 1 does not come into contact with the air and, in addition, since the side face of the through section is coated with the layer 3, the material 1 on the side face of the through section is also prevented from coming into contact with the air. Therefore, even when the material 1 is removed from the manufacturing line and temporarily stored, the discoloration 4 of the material 1 by rust, etc., caused over aging does not occur.
