Title: Photoconduction type liquid crystal light valve
Inventor: YOKOI HIROSHI
IPC: G02F1/135
Filed: 1990-10-04
Abstract: PURPOSE:To joining transparent substrates across a uniform gap and to obtain a projection image with superior resolution by making the coefficient of thermal expansion of the transparent substrate which seals a write side smaller than that of the transparent substrate which seals a read side. CONSTITUTION:The 1st transparent substrate A which is arranged on the write side and the 2nd transparent substrate B which is arranged on the read side are sealed with thermosetting resin 22 at high temperature with liquid crystal orienting films 4 and 3 in while the proper gap is held by spacers 2. The coefficient alphaB of thermal expansion of the substrate B is larger than the coefficient alphaA of the substrate A, so the substrate B absorbs the curvature of the substrate A which is generated at the time of the filming of a-Si in addition to the thermal expansion of the substrate A which is caused at the time of heating and the thermosetting resin 22 is solidified in this state, so that while the substrates A and B are united after being cooled, the external abutting surface of a fiber plate 11 is corrected into a plane. Consequently, the photoconduction type liquid crystal light valve which forms a projection image with superior resolution while the gap is uniformed is obtained.

Title: Snap operated switch and method of producing same
Inventor: TOOMASU EICHI SUTAANZU
IPC: H01H13/70
Filed: 1984-12-19
Abstract: A switch module includes a base and an array of one or more switches spaced adjacent to one another on the base. Each switch includes a fixed contact as well as a moving contact and supporting arm therefor. All of the switches in the array are formed from a single planar conductive blank composed of a closed frame and first and second sets of opposed elongated cantilevered panels extending from opposite sides of the frame, one set of panels forming the stationary contacts and the other set of panels forming the moving contacts and supporting arms therefor. The blank is deformed to move all of the corresponding stationary and moving contacts into overlapping relation and to give bias to all of the contact arms so that they urge the associated moving contacts into or out of engagement with the corresponding fixed contacts. All of the switches while they are still integral parts of the deformed blank are mounted to the base so that the relative positions on the base of all of the switch contacts are predetermined by their positions in the deformed blank. Finally, the deformed mounted blank is severed at selected locations to electrically isolate some or all of the switch contacts mounted to the base. Various blanks for making the switch module are disclosed as is the method for doing same.
