Title: Self-control type valve and evacuation method for evacuated chamber
Inventor: KOIWA KENSUKE
IPC: B01J3/02
Filed: 1988-06-24
Abstract: PURPOSE:To prevent dust from being floated when the gas is evacuated from a evacuated chamber and to eliminate the fluctuation of the pressure in the evacuated chamber by using the valve provided with the valve body controlling the evacuation quantity of the gas to be discharged and with the means controlling by itself the opening and closing of the valve body. CONSTITUTION:A valve body 2 controlling the evacuation quantity of the gas to be discharged, and a spring 3 controlling by itself the opening and closing of the valve body 2 are provided in the valve 12 used for evacuating the gas in the evacuated camber 10. Namely, when the evacuated chamber 10 is evacuated by a vacuum pump 11, a self-control is carried out by the relative relation between the pressure difference of the pressure of the evacuated chamber 10 to the pressure at a valve seat 1 in the side of vacuum pump and a compressing force of a spring 3 so that the continuous evacuation of the gas in the evacuated chamber 10 is carried out without abrupt fluctuations of pressure. As a result, the dust is prevented from floating up in the early period, the pressure in the evacuated chamber is speedily reduced in the middle period, and in the latter period the pressure in the chamber is slowly changed during evacuation.

Title: Magnetic disk device
Inventor: HINOBAYASHI TAKEO
IPC: G11B5/48
Filed: 1978-12-21
Abstract: PURPOSE:To avoid perfectly the abrasion and the lacking which occur to the core gap by locating the magnetic head so that the flat part including the core gap may be inclined with a fixed angle to the tangent of the track on the disk. CONSTITUTION:The magnetic head is located so that flat part 22-3 including core gap 24 may be inclined by fixed angle theta to tangent 32. This angle theta is decided by Eq. I, where L is the length between core gap 24 and boundary 25-3 at part 22-3 and W is the core width each. And the angles larger than this will do, but the upper limit is set to 20 deg. to be preferably set to 10 deg. or less. In such way, the magnetic head is located with some inclination to the track tangent, and thus the abrasion and lacking occurring to the core gap can be avoided perfectly. As a result, the reliability can be increased for the disk device.

Filed: 1986-07-05
Abstract: PURPOSE:To prevent use of counterfeit CD card by keeping serial number of use in a customer record of a customer file in magnetic stripes of a CD card and a central computer, and renewing the number every time the CD card is used. CONSTITUTION:The same number is held in magnetic stripes of a CD card and in the file of a central computer. The numbers are compared, and when they coincide, both numbers are rewritten. That is, a serial number of use renewal module 5 subtracts amount of cash withdrawal inputted by an operator of a cash dispenser 1 from balance of deposit of customer record read out from a secret code number check module 3, and at the same time, adds '1' to the serial number of use in relevant customer record and in the magnetic stripes, and rewrites a customer file 2 and gives command to the cash dispenser 1 to discharge cash and to rewrite the magnetic stripes. In the case where copied and counterfeit CD card is used, the serial number of use becomes discordant as the serial number of use of another CD card is not renewed, and accordingly, cash is not discharged.

Title: Dry etching method
Inventor: ODA TAKAFUMI
IPC: H01L21/302
Filed: 1990-06-14
Abstract: PURPOSE:To get such a dry etching method as to perform uniform etching in such a case that the thickness of an SiO2 film on the periphery of a wafer is thicker than the center by using oxygen, CF4, or CO2 for the cooling gas to be supplied to the rear of the wafer. CONSTITUTION:In etching the SiO2 films 14 and 19 on a wafer 3, oxygen is used for cooling gas 10a. It follows that cooling gas 10a flows along the routes 11 and 12, and as a result, O2 concentration on the periphery of the wafer 3 rises. Accordingly, the under-surface distribution of etching rates in the SiO2 films 14 and 19 becomes approximately equivalent even at the wafer end 3 to the center of the wafer 3, and the sharp etching rate drop at the end of the wafer 3 vanishes. Accordingly, the etching rate distribution under the surface of the wafer can be adjusted, and by applying uniform etching under the surface, it has a high effect upon the improvement of the yield rate and the performance of a semiconductor device manufactured and the stabilization of its quality.
