Patent JP-S6126832-A (JP)
Title: Pressure sensor
Inventor: NATSUMEDA TAKESHI
IPC: G01L9/00
Filed: 1984-07-17
Abstract: PURPOSE:To improve nonlinearity due to variation in effective pressure reception area which is caused by the displacement of a diaphragm by canceling the displacement of the diaphragm by the reaction force of a spring provided additionally when the displacement of the diaphragm attains to a constant value. CONSTITUTION:When the displacement to the recess side of a diaphragm groove exceeds the specific value according to a rise in pressure and the effective pressure reception area of the diaphragm increases to some extent, the distances between the grooved diaphragm 1 and sealed casings 4 and 5 become shorter than the free length of the 3rd spring 13, which is compressed to produce reaction force. Consequently, the displacement to the recess side of the diaphragm groove is prevented from increasing abruptly corresponding to an increase in the effective pressure reception surface fo the diaphragm and the nonlinearity of the pressure sensor is improved.

Abstract: PROBLEM TO BE SOLVED: To eliminate defective application due to casting at side and to stably operate an ash melting furnace for a long time by lining the side wall of the ash melting furnace with the mixture of silicon carbide and alumina in a specified ratio. SOLUTION: The material obtained by mixing 5-90 wt.% silicon carbide reacting with molten slag to increase its viscosity and effectively checking the infiltration of slag into the refractory and 5-90 wt.% alumina developing medium and high-temp. strength is precast into a block. Consequently, the erosion of the bond used at the bottom, tuyere, trough, ceiling, etc., of the ash melting furnace for decreasing the volume of the incineration ash and fly ash discharged from a refuse incinerator, etc., and further melting the slag by the heat of plasma, etc., is reduced. When the silicon content is <5 wt.%, the slag viscosity is not sufficiently increased, silicon carbide reacts with the oxygen in the air to form silica at >90 wt.%, and the slag viscosity is not increased.

Abstract: PURPOSE:To obtain an excellent and stable output which has no temperature dependency over a wide temperature range and to facilitate integration by obtaining a reference voltage which sets a constant current value generated by a constant current circuit from a reference voltage sources which has not temperature dependency. CONSTITUTION:Photoelectric conversion outputs VS1 and VS2 from operational amplifiers 4a and 4b which are obtained by compressing photocurrents I1 and I2 logarithmically are supplied to bases of NPN transistors (TR) Q1 and Q2 which are connected differentially, and their emitter sides are connected in common. Further, a TR Q3 for constant current driving and a resistance R2 are connected to the common connection point in series. The TR Q3 is driven with the constant current because the voltage across the resistance R2 is held constant by an operational amplifier 4c. The reference voltage Vr which is used for setting a prescribed current and has no temperature dependency is supplied from a reference voltage source 5 to the '+' input terminal of the amplifier 4c of this constant current circuit. Consequently, the temperature dependency is canceled and a stable output is obtained.
