Title: Continuous film forming device
Inventor: URA KAZUHIRO
IPC: C23C14/56
Filed: 1992-12-07
Abstract: PURPOSE:To surely form a desired good-quality film each time by interposing a holder cleaning chamber between the loading and unloading chambers. CONSTITUTION:This multi-chamber sputtering device consists of a chamber 5 for loading a substrate 3, a chamber 6 to heat the substrate, a first film forming chamber 7, a protective film forming chamber 8, a chamber 9 to unload the coated substrate 3 and a chamber 10 for cleaning a holder 17 for the substrate 3. The holder is reversively sputtered by a cleaning means 37 in the chamber 10 with the holder 17 as a cathode and a housing as the anode to remove the film forming material depositing on the holder 17 to be cleaned. Since the cleaned holder 17 is used in the succeeding film forming stage, a thin film of specified quality is formed, the film forming material is not left on the holder, and hence an abnormal discharge is not generated.

Inventor: TANAKA OSAMU
IPC: F25B13/00
Filed: 1989-12-14
Abstract: PURPOSE:To prevent an abnormal shutdown of a compressor of an air conditioner by a method wherein a bypass line remains open even when a period, for which the compressor is prohibited to restart, has elapsed after the compressor is shut down, and the compressor is started after the bypass line which has been closed is opened. CONSTITUTION:A compressor 1 is prohibited to start for a period a first set time period elapses after the compressor 1 is shut down by a controller 6, and a bypass line 42 is kept open until a second set time period elapses. When the second set time period is set at a time period during which the difference between the high and low pressures of the compressor 1 is satisfactorily equalized, and the compressor 1 is restarted, the compressor 1 starts with a little difference between the high and low pressures. And, when the second set time period has passed and a start request signal of the compressor 1 is input after the bypass line 42 is closed, the compressor 1 is started after an on-off valve 42a is opened for a specified time period. Thereby, the compressor 1 can be continuously operated without an abnormal shutdown.

Abstract: PROBLEM TO BE SOLVED: To provide a nonvolatile semiconductor memory together with the erasing method wherein self-convergence speed, life time, and reliability are improved. SOLUTION: After erasing of a memory cell, a voltage is so applied to a control gate 60 and source/drain regions 46 and 48, that only with those that do not cause channel hot carriers, and a back bias voltage is applied to a P-well region 42 of a semiconductor substrate 40 to widen a depletion layer of a channel region for generating channel hot carrier, for self convergence operation.
