Patent KR-940008433-B1 (KR)
Title: Method of removing frost in air conditioner
Inventor: KIM TAE-DOK
IPC: F24F11/02
Filed: 1991-08-10
Granted: 1994-09-14
Abstract: The method for controlling defrost of a combined heating and cooling-air conditioner is disclosed in executing a defrost operation by changing differently a driving frequency of a compressor according to the defrost operation time and the outdoor piping temperature. The method includes the steps of: an initial defrost driving for judging at defrost mode if the outdoor piping temperature is over a determined temperature; a heating driving for driving the compressor by a first driving frequency to heat; a first defrost driving for driving or controlling the compressor; and a second defrost driving.

Title: Element segregation method for semiconductor memory device
Inventor: KIM YONG-BAE
IPC: H01L21/76
Filed: 1991-08-27
Granted: 1994-04-16
Abstract: The isolation method comprises the steps of; forming an oxide layer on a semiconductor substrate and injecting nitrogen ion into said oxide layer to nitridate said oxide layer; depositing nitride layer on said nitride-oxide layer, injecting channel blocking ion, pattering isolation region, etching said nitride layer and etching said nitride-oxide layer; forming sacrificial layer for removing ions in active region and removing said sacrificial layer. The produced memory device prevents corrosion of the side surface of the field plate isolation region.
Patent KR-100189727-B1 (KR)
Inventor: PARK NAM-KYU
IPC: H01L27/04

Title: Method of forming heat shrinking tube
Inventor: YANG JI-SONG
IPC: B29D23/00
Filed: 1991-12-09
Granted: 1994-10-18
Abstract: The heat-contractable tube is prepd. using by multi-inclined molding tube with the slope ratio of 0-40o. The inclined molding tube comprises: (A) diameter of an introduced parallel part (11) to be greater than it of expanded tube; (B) slope part (12) with slope ratio of 1/100 or 1/200; (C) discharged parallel part (13) having the diameter of 1.2-1.4 times larger than (11); (D) many expansive tubes (1) consisting of (13).
