Abstract:
An anisotropic conductive film made of an adhesive resin composition in which conductive particles are dispersed. The adhesive resin composition is a thermosetting resin composition containing base resin composed of polyacetalized resin obtained by acetalizing polyvinyl alcohol and/or modified polyacetalized resin obtained by introducing an aliphatic unsaturated group in a side chain of the polyacetalized resin, melamine-series resin, (meth)acrylate phosphate, and alkyd resin. The present invention provides an anisotropic conductive film exhibiting high adhesive strength to both ITO and SiOx.
Abstract:
An anisotropically electroconductive film, which has a high reliability in its capacity for conducting electricity and also a good adhesion under such an adhesive condition that the film is heated at a temperature of 130° C. or less for a short period of time, has a layer of an adhesive within which electroconductive particles are distributed. The adhesive is composed of a thermosetting resin composition including a base resin, a reactive compound, an organic peroxide and a reaction accelerating compound, and also the electroconductive particles incorporated into the thermosetting resin composition. The base resin is a polyacetalized resin which is obtained by acetalizing a polyvinyl alcohol. The reactive compound is at least one selected from a group consisting of acryloxy group-bearing compounds, methacryloxy group-bearing compounds and epoxy group-bearing compounds. The reaction accelerating compound is a compound which has a radically reactive group and alkali-reactive group as its end groups.

Abstract:
A method of making an optical transmission tube comprises having a tubular clad and a core covered with the tube and having a refractive index higher than the clad. The core has light-scattering particles uniformly dispersed in or throughout the core, so that light passing through the core is reflected and scattered at individual scattering particles to permit the light to be emitted from outer surfaces of the clad.
Abstract:
An adhesive composition for use in joining a polarizer plate to a substrate of a liquid crystal cell contains as a main component (1) an ethylene-vinyl acetate copolymer, (2) a copolymer of ethylene, vinyl acetate, and an acrylate and/or methacrylate monomer, (3) a copolymer of ethylene, vinyl acetate, and maleic acid and/or maleic anhydride, (4) a copolymer of ethylene, an acrylate and/or methacrylate monomer, and maleic acid and/or maleic anhydride or (5) an ionomer resin in the form of an ethylene-methacrylic acid copolymer having a metal ion for binding molecules thereof.

Abstract:
A laminated glass is composed of glass plates, between which a thermosetting resin composed of a copolymer of ethylene-vinyl acetate, a hydrocarbon resin and an organic peroxide is inserted and cured to intergrate them. An organic resin film is inserted between layers of the thermosetting resin. The thermosetting resin contains dibenzylidene sorbitol and/or tribenzylidene sorbitol. The thermosetting resin contains one or more kinds of silane coupling agent selected from the group consisting of acryloxy group containing compound, methacryloxy group containing compound and aryl group containing compound, and an absorber for ultra violet ray are contained. Preparation of the thermosetting resin is carried out by previously mixing a part of the copolymer of ethylene-vinyl acetate with the hydrocarbon resin to obtain a mixture, mixing residual amount of the copolymer of ethylene-vinyl acetate into the mixture, and adding the organic peroxide to mix.
Abstract:
A germfree drinking water dispenser includes a reservoir for receiving and reserving drinking water such as mineral water and an ozone injecting device. The ozone injecting device includes a compact ozone generator and an injection opening which is opened into the reservoir. Ozone generated by the ozone generator is injected, by e.g. a blower, through the injection opening into the drinking water at the reservoir. The ozone injecting device is activated only for a short necessary period of time when the dispenser is out of service. So that, after the drinking water in the reservoir is fully sterilized, a sufficient period of time is allowed to lapse for any ozone remaining in the water to dissolve until the next first use of the dispenser.
