Title: Ffd control method in pabx
Inventor: SHIN JONG-KEUN
IPC: H04M3/22
Filed: 1987-09-28
Granted: 1990-10-06
Abstract: The control method is for correcting or changing the data and program without interruption of the telephone exchange. When the floppy disc driver is running, the present data is stored into a memory and the telephone exchange function is performed continuously. But when the floppy disc driver is not used, the read/write commands for changing the data or program are given to the driver. When the driver does not complete the data change but another call for the telephone exchange is entered, the rest of data is stored into the memory and the telephone exchange function is performed preferentially.

Title: Abrasive grains in the shape of platelets
Inventor: KRUSCHKE HOWARD
IPC: B24D11/02
Filed: 1988-11-22
Granted: 1996-11-20
Abstract: This invention relates to abrasive grains, and, more particularly, abrasive grains having a particular shape and size. Three basic technologies that can be employed in the production of shaped abrasive materials suitable for use as abrasive grains are fusion, sintering, and chemical ceramic. However, it is not known whether any particular shape or size of abrasive grains would provide enhanced properties with respect to abrading. This invention provides abrasive grains having a shape such that the mean particle volume ratio thereof is less than about 0.8, and preferably ranges from about 0.3 to about 0.7. Typically, the grains have the shape of a thin platelet, the average thickness of which must be no greater than about 460 micrometers. The abrasive grains of this invention can be used in coated abrasive products, bonded abrasive products, nonwoven abrasive products, and abrasive brushes. The products made with the grains of this invention exhibit higher initial cut and higher total cut, along with lower grinding forces than do products having equivalent weight loadings of conventional abrasive grains.

Abstract: 본 발명은 일정한 표시 흐름을 공급하는 음속에서 작동되는 제류부를 각각 구비하고 있고 흐름조절기가 구비된 배출관을 하류에 각각 가지고 있는 분석될 가스 라인, 제로 가스 라인 및 보정 가스 라인을 포함하고 있는 초고감도 분석기로의 가스 공급 방법 및 장치에 관한 것이다. 
     제1라인과 제2라인의 표시 흐름은 분석기에 공급되는 기지 흐름보다 더 많아서, 분석 단계의 보정 중에 장치의 흐름 부위의 전체가 라인의 표시 가스 및/또는 다른 라인으로부터 발생되는 가스의 재순환 흐름의 일부분에 의해 영구히 플러시 된다.

Abstract: The method is for forming fluorescent layer of color brown tube to improve light emitting coefficient. The method comprises the steps of: (A) vaporising aluminium on a face plate in a thickness of 30-40 angstroms under temperature of 300-400 degree; (B) spraying fluorescent on the inner side of face plate; and (C) exposing ultraviolet and cleaning surface.

Granted: 1995-01-27
Abstract: The method includes the steps of forming on insulating layer (22) and a 1st hard mask layer (23) on the Si substrate (21) to form a photoresist pattern (25) on the layer (23), anisotrophically etching the layer (23) to form a 1st hard mask pattern (23') to etch the layer (22) isotrophically to form an opening part (27) to remove the pattern (25), forming a 2nd hard mask layer (24) thereon to form a 2nd hard mask spacer (24') on the side wall of part (27) by a blanket dry etching process, and anisotrophically etching the layer (22) by using the pattern (23') and spacer (24') as etching barriers to expose the substrate to form a contact hole with reproducibility, thereby preventing the layer (22) of the corner portions of spacer (24') from being etched.
