Abstract: PURPOSE:To avoid a decrease of performance and service life in a bush assembly by compressing a circular annular protrusive streak, having a size larger than the peripheral surface of an elastic member, to the inner in a diametric direction by a connecting part to be forced to come into press contact with the connecting part. CONSTITUTION:Placing bush assemblies 10, 11 butt facing to each other as paired one set and inserting both their outer cylinder members 2 into both ends of an eye hole 12 set to one side connecting member, an elastic member 4 forms its circular annular protrusive streak 4a larger in size than the periphery of the outer cylinder member 2 to be compressed to the inner in a diametric direction by an internal peripheral surface of the eye hole 12 and forced to come into press contact with the internal peripheral surface. Accordingly, preventing a muddy material or the like, which infiltrates from a metal fitting part between both the outer cylinder members 2 and the eye hole 12, from more infiltrating by the cylindrical protrusive streak 4a forced to come into press contact with the internal peripheral surface of the eye hole 12, a sliding member 5 can be prevented from its corrosion. Accordingly, the bush assemblies 10, 11 can avoid a decrease of performance and service life.

Title: Color liquid crystal display element
Inventor: FUJIEDA MASAYOSHI
IPC: G02F1/1333
Filed: 1989-10-11
Abstract: PURPOSE:To save the cost for light shielding means formation by extending a color filter to below the sealing member at the peripheral part of a liquid crystal cell. CONSTITUTION:A color filter film 6 is extended to below the sealing material 2 at the periphery of the liquid crystal cell. Namely, the color filter 6 is formed of an organic thin film which has black light shielding stripes 5 between the parts of respective colors and its light transmissivity is about 15%. This, therefore, sufficiently serves as a light shielding means. Further, the area of the peripheral sealing part is extremely small compared with the display part area of the liquid crystal cell and even when the color filter 6 is extended to below the sealing member 2, the increase in the cost is extremely small. Consequently, the color display element whose cost is reduced is obtained.
