Filed: 1979-09-18
Abstract: PURPOSE:To easily and exactly perform the density measurement which is free from an error due to influence of bubbles, by controlling the conduction between the pressure debubbling chamber and the pipe, by means of the valve, and also controlling the pressure to the pressure debubbling chamber. CONSTITUTION:A liquid flowing in the pipe 11 is made to flow into the pressure debubbling chamber 12 by dynamic pressure. And when the actuator 16 is demagnetized, the passage port 13 is closed by the valve part 17a of the plunger 17, and communication between the pipe 11 and the chamber 12 is cut off. When pressure is put through the pressure pipe 14, a liquid flowig into the chamber 12 is debubbled and the density which is not influenced by bubbles is measured exactly by use of the densitometers 15a, 15b, etc. Subsequently, when pressure is put on the chamber 12 through the pipe 14 by opening the valve 17a, the measured liquid in the chamber 12 is returned into the pipe 11, and when it is stopped to pressurize by the pipe 14, the liquid in the pipe 11 is replaced and made to flow into the chamber 12. Accordingly, the density measurement which is not influenced by bubbles can be peformed easily and exactly.

Title: High-frequency wave plasma treatment apparatus
Inventor: MIYATA KENJI
IPC: H01L21/3065
Filed: 1995-05-18
Abstract: PURPOSE: To enable high speed cleaning in a plasma generation room by adjusting plasma density distribution in a high-frequency wave plasma treatment apparatus to suppress wall surface chipping. CONSTITUTION: A degree of plasma diffusion in horizontal direction in the plasma 10 is adjusted and plasma density distribution in the horizontal direction is adjusted by constituting a local magnetic field configuration having main component toward central axis with magnetic field coils 1a, 1b only in the area near a side wall 31 of the plasma generation room 3 and adjusting the magnetic field intensity distribution in the plasma 10. At the time of discharge washing with cleaning gas, the cleaning is highly speeded up by intensifying an interaction between gas and wall by lessening the main magnetic field on the wall surface.  Thereby, the adjustment of the plasma density distribution is possible and the high speed cleaning is possible on the inside wall of the plasma generation room after suppressing and lessening any foreign object generation due to the wall surface chipping and after securing a plasma confinement.

Abstract: PURPOSE:To obtain a valve means capable of reducing the valve noises and lowering its manufacturing costs, by disposing a valve fixing plate formed with a fluid passing hole and a valve fixed at its root portion to the valve fixing plate and adapted to close the fluid passing hole at its free end portion in one fluid passage formed in a pulse combustion device. CONSTITUTION:By the rising of pressure in a combustion chamber 1 caused after explosion, an air valve 8' closes a fluid passing hole 7a formed in an air valve fixing plate 7 while a gas valve 11' closes a fluid passing hole 10a formed in a gas valve fixing plate 10, so that combustion gas is discharged to the outside from a tail pipe 2. Here, since the fluid passing holes 7a, 10a formed in the air valve fixing plate 7 and the gas valve fixing plate 10 are closed respectively by the resilient valves 8', 11' gradually from their fixed root portion toward the free end part, the mass of the valves coming into contact with the plates 7, 10 per unit time is reduced, so that the shock caused at the time can be alleviated and the valve noises can be reduced resultantly. Further, since a back plate requiring high accuracy in maching the same can be omitted, it is enabled to lower the manufacturing costs.

Filed: 1988-05-17
Abstract: PURPOSE:To improve the quality of an input pattern in a simple constitution with the handwriting input of a touch sensor by detecting the coordinates of all pushed keys in a single scanning action in case plural keys are pushed at one time. CONSTITUTION:The X direction coordinate data (X coordinates) is applied to a decoder 2 from a CPU 6 via an I/O port 1 and the decoder 2 decodes the X coordinate data for selection of one line set in the direction X. The selection data is given to a selector 4 from the CPU 6 via the port 1. This selection data shows the specific one of gates a21-g27 set in the direction Y and to be selected. Thus the scan data equivalent to eight lines out of all lines set in the direction Y is sent to the port 1 from the gate a21 selected by the selector 4. In such a way, the lines of an input pattern are never zigzag when the handwriting input is carried out by fingers via a touch sensor. Then an input pattern of high quality is obtained in a simple constitution.
