Abstract: A forming method of photoresist patterns comprising the step forming a photoresist layer on the substrate which layers to be patterned are formed; the step forming a inorganic layer on said  photoresist layer; the step doping impurities in said inorganic layer ; the step selectively forming insoluble compound on the surface of said inorganic layer by effecting selective exposure process through prescribed masks; and the step selectively removing the nonexposed inorganic layer and photoresist by developing process is disclosed. Thereby, it is possible to remove arc antireflective coating metal loss which can be occurred in metal wiring patterning process because selectivity of the photoresist is enhanced in plasma etching.

Title: Control apparatus and the method of low frequency vibration washing machine
Inventor: LEE JOO-HWAN
IPC: D06F19/00
Filed: 1993-10-19
Granted: 1996-10-14
Abstract: The apparatus executes control of washing machine to minimize electric power consumption by resonating the mixture of water, detergent and air with small amount of electric power compared to conventional washing machine. The apparatus includes : the first(12) and the second (12a) resonators in the water basin; the first(14) and second(14a) motors and the driving units(16)(16a) for motors, memory unis(18) storing a phase angle table; a microprocessor(19) which contols phase difference and frequency; a phase delay units(20) which delays phase according to phase delay command from the micropressor; and a time delay unit(21) which adjusts the frequency of the control signal from the microprocessor.

Title: The structure of an optical path regulating apparatus and a manufacturing method
Inventor: JI JUNG-BUM
IPC: H04N5/74
Filed: 1993-11-09
Granted: 1997-04-29
Abstract: A method of fabricating an optical path controller of a projection-type image display includes the steps of selectively forming a ceramic layer 21 on a driving substrate 20 and forming a sacrificial oxide layer 22 on a predetermined portion of the driving substrate 20, other than the ceramic layer region 21, forming a ceramic layer 23 on the overall surface of the driving substrate, selectively removing a predetermined portion of the ceramic layers 21 and 23 to torm a trench, filling a metal 24 in the trench and forming a signal electrode 25 on the surface of the ceramic layer 23 including the metal region 24, selectively forming a ceramic layer 26 on the ceramic layer 23 including the signal electrode region 25 and forming a bias electrode 27 on an exposed surface of the substrate, selectively removing an unnecessary portion of the bias electrode 27 and ceramic layer 26 to pattern the them by a plurality of pixels, selectively forming a ceramic layer 28 on each bias electrode 27, forming a sacrificial oxide layer 29 on an exposed surface other than the ceramic layer region 28 and forming a ceramic layer 30 on the overall surface of the substrate, patterning the ceramic layer 30 and driving substrate 20 by pixels, removing the sacrificial oxide layers 22 and 29 and forming a mirror 31.

Title: Microemulsion composition comprising cholesteryl derivatives and translucent cosmetic material using it
Inventor: BAE DUK-HWAN
IPC: A61K8/06
Filed: 1993-11-12
Granted: 1997-04-29
Abstract: Microemulsion is manufactured by mixing oil phase raw material mixed 5-15 wt.% of cholesteril derivatives, 5-15 wt.% of block copolymer nonionic surfactant, 5-15 wt.% of general nonionic surfactant, and  5-15 wt.% of coupling oil and an aqueous phase raw material mixed 10-30 wt.% of polyol and purified water. The cholesteril derivatives are one or more component selected from cholesteril acylglutamate, oleinic acid cholesteril, isostearic acid cholesteril, macademianut oil fatty acid cholesteril, 12-hydroxy stearic acid cholesteril, stearic acid cholesteril, and nonanic acid cholesteril. Cosmetic by the use of microemulsion shows a good stability of retension, moisturizability , and serviceability.
