Title: Differential pressure measuring instrument
Inventor: MORITA SAICHIRO
IPC: G01L13/00
Filed: 1988-05-31
Abstract: PURPOSE:To reduce the cost of a differential pressure measuring instrument by constituting the main body section of the instrument and a cross valve in one body. CONSTITUTION:When a stop valve is opened and a uniform-pressure valve is closed, measuring pressures are applied to the main body 11 of this differential pressure measuring instrument from the right and left sides and a measurement diaphragm 13 is displaced by the differential pressure between the two measuring pressures. Because of the displacement of the diaphragm 13, the electrostatic capacities of fixed electrodes 133 and 134 and the diaphragm 13 differentially change and an electric signal output is obtained in corresponding to the differential pressure. When the zero point of the instrument is adjusted by making both measuring inputs of the instrument uniform, the zero point adjustment is performed after the uniform-pressure valve is opened. Therefore, the main body section of the instrument and a cross valve can be constituted in one body and the cost of the instrument can be reduced.

IPC: H01L21/66
Filed: 1979-10-19
Abstract: PURPOSE: To simplify the deterioration detection of the diode by inserting, between a connecting jack board and the diode to be tested, a diode in the same direction as the diode to be tested and a backward light-emitting diode in parallel with said diode.  
     CONSTITUTION: A unit sheet 2 provided with diodes D 1  and D 2  is connected to a connecting jack board 1 through the diode deterioration detector 3. The deterioration of the diode D 1  and D 2  is detected by detecting the potential variation at a terminal (e) due to the application of a given voltage to input terminals (a) and (d). On the other hand, in the detector 3, a diode D 0  in the same direction as the diode D 1  and a backward light-emitting diode DC in parallel with the diode D 0  are inserted, so that the diode DC is turned on by a leakage current (i) produced according to the deterioration of the diode D 1  when it deteriorates. Therefore, the lighting degree of the diode DC permits the deterioration of the diode to be readily and speedily detected, and moreover this prevents the production of wrong decision or the like resulting from the voltage fall due to a leakage current in another circuit (c) to be connected to (a) contact (b) of the jack board 1.
