A light emitting device, comprises a LED chip, and a case having an accommodating recession accommodating the LED chip, wherein the light emitting device emits light from an opening portion of the accommodating recession, the case is monolithically formed by injection molding of a resin composition preparing by mixing fine grains of specular reflection material and glass fibers as diffusion reflecting material as fillers therein, an inner surface of a side wall portion of the case works as a reflector that reflects the light emitted from the LED chip so that the light is output from the opening portion, and a thickness of the side wall portion is selected to be smaller than an average length of the glass fibers.

Light emitting device including a case having an accommodating recession

A polyvinyl chloride composition comprising polyvinyl chloride having dispersed therein platelet aluminum powders, characterized in that the aluminum powders have a diameter of at least 10.mu. and are used in an amount of 0.2-10 parts by weight per 100 parts by weight of the polyvinyl chloride. This composition affords by molding a weather-resisting resinous molded article of metallic luster in appearance.

Polyvinyl chloride composition

A steering wheel for a vehicle formed from a molded polyurethane resin and a molded vinyl chloride resin which contains a heat stabilizer consisting of (I) 1 to 3 phr of the organo maleate, (II) 1 to 4 phr of zinc soap and 0.3 to 1.0 phr of an organo-phosphite, or (III) 1 to 3 phr of organotin maleate, 1 to 4 phr of zinc soap and 0.3 to 1.0 phr of an organo-phosphite.
