IPC: G02F1/1337
Filed: 1988-12-26
Abstract: PURPOSE:To prevent the influence of the internal polarization phenomenon which arises when a polyimide resin is used as an oriented film by using a picture element electrode substrate which has insulating protective films laminated on a part of respective picture element electrodes and the oriented film of the polyimide resin covering the respective picture element electrode parts which are not laminated with the insulating protective films. CONSTITUTION:After gate wirings, source wirings 14, TFTs 15 and the picture element electrodes 12 are formed on a transparent substrate 11, silicon nitride (SiNx) is formed to a prescribed thickness. The SiNx film is coated with a photoresist and is subjected to mask exposing then to etching with hydrofluoric acid to remove the SiNx film laminated on the parts, exclusive of the peripheral edges, of the picture element electrodes 12 and the SiNx film laminated on the unnecessary parts, such as junctures to external terminals. The insulating protective films 16 are then formed. The polyimide resin is thereafter laminated over the entire surface on the side laminated with the insulating protective films 16, by which the oriented film 17 is formed. The generation of the internal polarization is suppressed in the parts where the oriented film of the polyimide resin is directly laminated on the picture element electrodes. The high-grade display which is free from the degradation and unequalness of contrast is thus obtd.

Abstract: PROBLEM TO BE SOLVED: To improve connecting strength by arranging a plural number of vertical cylindrical stone packed cages extended by crossing brace wires for reinforcement on at least a cover net close to each other at a position of the brace wires and connecting adjacent brace wires to each other. SOLUTION: A stone packed cage 2 is constituted by radially providing a plural number of brace wires 4 for reinforcement passing through a center of a cover net and a bottom net to surround a vertical cylindrical cage main body. In case of laying the cage 2 on a river bed, etc., the adjacent cages 2 are made contact with each other at a position of the brace wires 4, and the brace wires 4 of the adjacent cages 2 are connected to each other at a connecting point 5. At this time, as the brace wires 4 as an overall structural body are connected to each other in a straight line, connecting force of the cages 2 with each other becomes extremely large.  Consequently, it is possible to certainly support external force of a water current, etc., in the positionally slipping direction working on the stone packed cage, to prevent deformation of a connecting part of the stone packed cage and breaking of connection between the stone packed cages, and as the river bed makes contact with flowing water and atmospheric air through a proper clearance formed between the stone packed cages, it is possible to form natural and favourable ecological environment.
