Title: A method of generating an alignment direction on an alignment surface for a liquid crystal display cell
Inventor: CHAUDHARI PRAVEEN
IPC: G02F1/1337
Filed: 1997-05-19
Granted: 2001-06-07
Abstract: A method of generating an alignment direction on an alignment surface for a liquid crystal display cell comprising: directing a particle beam at said alignment surface; said particle beam is directed at said surface at an adjustable energy, at an adjustable angle with respect to said alignment surface and at an adjustable time to adjust the pretilt angle of a liquid crystal molecule with respect to said alignment surface. We have found that liquid crystals can be aligned on a polyimide surface exposed to a low energy and neutral Argon ion beam. The energy of the incident ions were varied between 75 and 500 dV, the integrated current density from 100 mu A/cm<SP>2</SP> to 500 mA/cm<SP>2</SP>, and the angle of incidence over which alignment was measured was between 10 and 80 degrees. The pretilt angle of the liquid crystals could be varied between 0 and 8 degrees, by controlling the processing condictions. Degradation of the polyimide, which leads to charge migration, can be avoided by operating at low accelerating voltages.

Title: A method for transferring a wafer
Inventor: KIM DEA-WON
IPC: H01L21/00
Filed: 1997-08-09
Granted: 2002-09-01
Abstract: There is provided a method for transferring a wafer using a gas providing means as well as a gas sucking means. According to the present invention, the process comprises steps of blowing a gas from suction cups which are connected to the gas providing means to the wafer supporting means through a gas transmitting tube, and picking up the wafer supporting means through the gas transmitting tube by the suction force of the gas sucking means after quitting blowing of the gas before contacting of the transferring means with the wafer supporting means. In this method, because the wafer is transferred by picking up the wafer supporting means after removing a washing solution from the wafer supporting means, it prevents a breakdown and performance deterioration of a transferring device caused by the remaining washing solution after the wafer washing step.

Title: Push-button switch
Inventor: TANABE YOSHIO
IPC: H01H1/46
Filed: 1998-07-03
Granted: 1999-12-01
Abstract: Push-button switch of prior art might experience difficulty of uniform flexible contact between a movable contact point and a pair of fixed contact points due to uneven bending of fixed contact points or displacement of slider cover that causes the shift of the center of contact. As a result, one side of fixed contact becomes worn that shortens the service of push-button switch. The invention relates to a push button switch comprising a sliding member (13) having a rectangular or elliptic retaining hole (13c), thus movable contact 14 can be freely arranged and moves in the direction perpendicular to the sliding direction of sliding member 13. As such, even if the center of contact between movable contact 14 and fixed contact 12 shifts, the displacement can be corrected easily by uniformly and flexibly holding a pair of fixed contact points 12, 12.
