Title: Adjusting method of sensitivity of level detection device
Inventor: YOSHIDA HIDEJI
IPC: F01M11/12
Filed: 1991-07-01
Abstract: PURPOSE:To adjust the sensitivity of a level detection device easily and in a short time without suing any weight or the like by a method wherein an adjustable resistance is connected to a piezoelectric oscillator, a resistance value at the time when the piezoelectric oscillator has been set to a state immediately before its oscillation in the air is found and the sensitivity is adjusted by using the value as a reference. CONSTITUTION:An adjusting resistor 10 is connected in parallel with a level detection device which is constituted of a piezoelectric oscillator 1, a self- oscillator 2, a transistor 3, resistors 4 to 6 and capacitors 7 to 9. Then, the resistance of the adjusting resistor 10 is adjusted, the piezoelectric oscillator 1 is set to a state immediately before its oscillation in the air, the value of the adjusting resistor 10 at this time is read out, and the set value of the adjusting resistor 10 is set according to a read-out resistance value and a set sensitivity. By adjusting the sensitivity, the piezoelectric oscillator 1 stops oscillating when a load at the set sensitivity or higher is applied. When the load is within a value according to the set sensitivity, the piezoelectric oscillator starts oscillating. By this method, the sensitivity can be adjusted in a short time even by a non-skilled operator.

IPC: C01B33/152
Filed: 1983-09-01
Abstract: PURPOSE:To enable the mass-production of quartz glass plate having high flatness, by manufacutring a thick dry gel by the sol-gel process from a metal alkoxide, sintering the dry gel, and slicing the obtained thick quartz glass. CONSTITUTION:Ethyl silicate is hydrolyzed with an aqueous solution of hydrochloric acid, mixed with fine silica powder, dispersed uniformly, and adjusted to 4-6pH. The obtained sol is poured into a deep vessel having flat bottom to a sufficient depth, and gelatinized and dried under free shrinkage to obtain a thick dry gel. The thick dry gel is sintered to obtain a thick quartz glass plate, which is sliced to a plurality of flat quartz glass plates having the required thickness to obtain a plurality of flat quartz glass plates at the same time. Since the dry gel prepared by this process has large thickness, it is resistant to warpage in drying, and gives the thick quartz glass plate having high flatness by drying. Accordingly, the process has high yield and is suitable for mass-production, and the flatness of the plate can be improved further by slicing.

Filed: 1980-11-13
Abstract: PURPOSE: To lighten the work load of an operator by guiding the secondary side fluid pressure to an operating lever of differential type to balance with the pressure acting on the operating lever.  
     CONSTITUTION: When an operating lever 24 of a relief valve 1 is operated the spring back force of a spring 9 changes due to the change of the pressure acting on an operating lever 15 with the operating direction of the operating lever 24.  A poppet valve 10 leaves a valve seat 6 when it receives the secondary side fluid pressure from its port 12 side to flow a part of the fluid pressure to a port 11, and the fluid pressure on the port 12 side is connected to a feedback chamber 21 via a passage 5, a piping 23 and a port 22. Thus the operating lever 15 receives a reaction force equal to the product of the cross sectional difference between a large diameter portion 19 and a small diameter portion 20 of the operating lever 15 and the secondary fluid pressure thereby balancing with the pressure acting on the operating lever 15.
