Title: Dry etching method
Inventor: HIJIKATA ISAMU
IPC: C23F4/00
Filed: 1989-08-29
Abstract: PURPOSE:To safely carry out etching with excellent etching rate, selectivity and anisotropy by using C2Br2F4 or C2BrF5 or those added with a specified amt. of SF6 as the gaseous reactant for dry etching. CONSTITUTION:A gaseous reactant is introduced into an evacuated chamber, and the surface of a sample set in the chamber is etched through plasma or reactive ion. In this dry etching method, C2Br2F4 or C2BrF5 or those gases added with 50vol.% SF6 are used as the gaseous reactant. The sample temp. is preferably kept at <=-20 deg.C when the gas contg. <=50vol.% SF6 is used. The gaseous reactant is excellent in the anisotropy, etching rate and selective ratio, and minute and precise etching is performed. Furthermore, the contamination of the chamber is reduced, clean treatment is realized, and the reactant is advantageous from the standpoint of safety since it does not contain chlorine, etc.

Abstract: PURPOSE:To decrease the man-hours of a manufacture process and to reduce the cost by supporting the surface of an insulating film at 80-90 deg. to a horizontal surface, and performing vapor deposition so that the thickness of a vapor- deposited of silicone monoxide rising vertically from a vapor-deposition source is at least 800Angstrom . CONSTITUTION:A transparent electrode 2 is formed on the transparent substrate 1 of the liquid crystal display panel and when the transparent electrode 2 is coated with the insulating film 12 by an oblique vapor-depositing means, silicon monoxide is vapor-deposited slantingly at a 80-90 deg. vapor-deposition angle until the vapor-deposited film thickness reaches at least 800Angstrom  while a transparent substrate 1 is held in a vapor-depositing device so that the vapor-depositing direction (arrow P) of silicon monoxide meets an orienting line direction. Consequently, while the high insulating film with superior step coating property is formed of a soft insulating film like cotton, no rubbing processing is performed, so an insulating film and orienting film 12 which has a required orienting function is obtained, the process is shortened, and the cost is reduced.

Title: Self diagnosing system of machine using microprocessor
Inventor: MURAYAMA TOMIO
IPC: G06F11/27
Filed: 1983-11-28
Abstract: PURPOSE:To enable to bypass sum check routine in the case of a specified value by setting a reference area for writing selectively in a memory either the specfied value or sum value besides a work area. CONSTITUTION:Sum check of a memory is performed by referring to the reference area R when a power source is made on, obtaining the sum from 0 address to 1B00 address when the value is other than FF, and judging whether lower two digits coincide with the reference area R. When the value written in the reference area R is FF, sum check routine is bypassed, and ordinary processing is continued deciding that the memory is normal. In the case where it is necessary to change the content of program temporarily, FF is written in the reference area R. Thus, it becomes unnecessary to execute sum check routine every time, and maintainability is improved.
