Abstract: A polyphenylene ether resin composition comprising (a) a polyphenylene ether resin, (b) a polyester resin, and (c) from 0.1 to 10 parts by weight, per 100 parts by weight of the total of the components (a) and (b), an epoxidized liquid polybutadiene having an oxirane oxygen content of at least 0.07% by weight. The composition is excellent in solvent resistance and mechanical strength.

Abstract: Polyphenylene ether compositions comprising a polyphenylene ether, an alkenylaromatic polymer, a rubber substance, a polyethylene or ethylenic copolymer, and a mineral oil. These polyphenylene compositions are excellent in the balance among fluidity, impact resistance and gloss.

Abstract: A composition comprising an amorphous resin (excluding polyphenylene ether) and a specific diamide compound of the formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are defined in the specification. The moldability of the amorphous resin is improved without reducing its heat resistance.

Abstract: An object moves along a predetermined route adjacent a pair of inductive radio lines crossed at two predetermined intervals P.sub.1 and P.sub.2. A sensing device on the object senses the intervals and enables generation of an object position signal having a first code value when the interval P.sub.1 is sensed and a second code value when the interval P.sub.2 is sensed.

Abstract: A process comprises the steps of molding a mixture of usual TiC powder material having a combined carbon content lower than the theoretical value, a required amount of binder metal and a suitable amount of WC powder, sintering the molded mixture at a high temperature of about 1550.degree. to 2500.degree. C. to dissolve the WC particles in the TiC particles, and maintaining the sintered product at the high temperature, whereby the combined carbon content is increased to the highest possible value approximate to the theoretical value and the binder metal is fully effectively fused to the surface of the TiC particles. The resulting product is readily crushable to a powder having greatly improved amenability to sintering.
