Title: Seal structure of bearing portion
Inventor: FUTAGAMI MASAHIRO
IPC: F16J15/18
Filed: 1994-09-16
Abstract: PURPOSE: To provide the seal structure of a bearing portion whose durability is high by restraining the generation of frictional heat by making slide smooth by sliding each seal ring between the inside surfaces of each recessed groove of a drive shaft through each resin film of a low friction coefficient. CONSTITUTION: In a case in which a drive shaft 1 and a housing 2 are rotated relatively, a seal ring 6 in a seal groove 1b follows the housing 2 and is rotated due to radial difference between its inner and outer peripheries. This seal ring 6 slides in the state of being pressingly contacted to the bottom surface and the low pressure side surface of the seal groove 1b at the drive shaft 1 through a resin film 5. The frictional coefficient of polytetrafluoroethylene to be used for the resin film 5 is extremely lower than that of polyphenylenesulfide which is the resin material of the drive shaft 1, so the seal ring 6 slides very smoothly and the generation of frictional heat is sufficiently small, and even in the case of the resin material being used for the drive shaft 1, the durability of the seal structure of a bearing portion can be increased.

Title: Liquid crystal panel and production thereof and liquid crystal projection type television
Inventor: TAKAHARA HIROSHI
IPC: G02B5/18
Filed: 1991-09-27
Abstract: PURPOSE:To enhance the brightness of a display screen without using polarizing plates for a liquid crystal panel and to obtain an image display having a high contrast. CONSTITUTION:Banks 16 for obtaining a diffraction grating 15 and a prescribed liquid crystal film thickness are formed by using the resin material of a high- polymer dispersed liquid crystal 18. The diffraction grating 15, etc., are produced by applying the resin on a counter electrode substrate 17 and bringing a mold plate into contact therewith. The refractive index of the diffraction grating 15 is equaled to the liquid crystal ordinary light refractive index of the high- polymer dispersed liquid crystal 18. A refractive index difference arises between the liquid crystal 18 and the diffraction grating 15 and the incident light on the liquid crystal 18 is diffracted and is scattered by the liquid crystal 18 when a voltage is not impressed to the liquid crystal 18. The rectilinear light is, therefore, extremely diminished. There is no more refractive index difference between the liquid crystal 18 and the diffraction grating 15 and the incident light advances rectilinearly when the voltage is not impressed to the liquid crystal 18.
