    摘要: An additional N.sup.+ region is provided in a P type substrate adjacent to a protective N.sup.+ resistor region with an insulating layer and metal layer interposed between the N.sup.+ region and the N.sup.+ resistor region. The N.sup.+ resistor region, the oxide layer, the polysilicon layer and N.sup.+ region constitute an MOS transistor, respectively corresponding to a drain region, a gate insulating layer, a gate electrode and a source region of the MOS transistor. When a very high excessive voltage that otherwise would destroy the PN junction between the substrate and the resistor region is applied to the input terminal, the MOS transistor is rendered conductive and the excessive voltage is absorbed.

    摘要: An object of this invention is to provide a method for the production of a porous cross-linked polymer, which permits the polymerization (curing) of a water in oil type high internal phase emulsion (HIPE) in such an exceptionally brief time as not more than 30 minutes, preferably not more than 10 minutes without impairing the stability of the HIPE. The object of this invention mentioned above can be accomplished by a method for the production of a porous cross-linked polymer which comprises steps of mixing an oil phase containing a polymerizing monomer, a cross-linking monomer, and a surfactant as essential components with a water phase containing water as an essential component thereby obtaining a water in oil type high internal phase emulsion and heating said emulsion to a prescribed curing temperature thereby polymerizing the emulsion, wherein said emulsion is formed in a thickness of not more than 50 mm and the temperature-increasing rate of the emulsion is not less than 5° C./minute.

    摘要: An epoxy resin composition which is tough and has excellent heat resistance and adhesion is obtained by dispersing, in an epoxy resin, polymer particles with a glass transition temperature of lower than 20.degree. C. obtained by emulsion polymerization of a (meth)acrylic acid ester monomer by using, as an emulsifier, an end alkyl group-containing polymer with an acid value of greater than 200 or a salt thereof obtained by polymerization of a polymerizable monomer containing an unsaturated carboxylic acid in the presence of an alkyl mercaptan. The epoxy resin composition is useful, for example, as adhesives, molding materials, paints, sealants.
