Title: Liquid crystal cell substrate
Inventor: YAMANASHI FUMIAKI
IPC: G02F1/1333
Filed: 1981-05-21
Abstract: PURPOSE:To avoid the deformation of a liquid crystal display device regardless of application of the external pressure and to prevent a reduction of the display quality which is caused by a disturbed arrangement of the liquid crystal molecules, by forming an insulated film including a spacer to cover the transparent electrode on an insulated substrate. CONSTITUTION:An insulated film 12 of SiO2 and a transparent electrode 13 are formed on an insulated substrate 11 of glass, etc. A paste of an organosilicon compound containing a spacer 2 of alumina beads, etc., an organotitanium compound, etc. is coated on the film 12 and the electrode 13 and then burnt  to obtain a transparent oxide insulated film 14 of SiO2, Al2O3, etc. The substrates 11 thus obtained are superposed on and sealed to each other, and the  liquid crystal is enclosed between the substrates. Thus a display element is obtained. The spacer 2 prevents the deformation of the liquid crystal element  due to the external force and avoids the disturbance of arrangement for the  liquid crystal molecules. As a result, a high-grade display is possible.

Filed: 1985-04-10
Abstract: PURPOSE:To prevent rear-end collision of vehicles by irradiating a guide light while sectioning it along the running route and detecting the presence of a vehicle in the irradiated section when a reply signal comes. CONSTITUTION:A guide light irradiation controller Ai irradiates the guide light fi via a slit Si to a vehicle W. The guide light fi is reflected in a reflection plate Ri, a reflected light vi is received by a photodetector Bi to generate a photodetecting signal Ri. The photodetecting signal Ri is inputted to a succeeding controller Ai+1. The controller Ai+1 uses the signal Ri to detect the presence of the vehicle W in the guide light irradiating section. When the presence of the vehicle is detected, the controller Ai+1 stops the irradiation of the guide light at the adjacent subsequent section to stop the subsequent vehicles in the subsequent adjacent section. Thus, the rear-end collision of vehicles is prevented.
