  • Publication number: 20040192822
    Abstract: A thin injection molded article is composed of a composite resin material of organic clay 2 dispersed in a polymer 1. The polymer comprises a blend of polyphenylene oxide and a butadiene-styrene copolymer. The relationship between the maximum flow length L of the composite resin material in the thin injection molded article and the average thickness t of the thin injection molded articles satisfies the inequality: L/t≧70.

  • Patent number: 5875750
    Abstract: In a rotational phase adjusting apparatus which may be used for controlling opening/closing timings of intake and exhaust valves of an internal combustion engine, one side wall of a housing is fixed to one of a driving member and a driven member, while the other side wall of the housing is made integrally with a circumferential wall of the housing. A seal made of a material less harder than the housing is provided between the housing and a vane. The housing is made of an aluminum while the seal is made of a PPS resin mixed with an inorganic filler. The inorganic filler is harder than the PPS resin but less harder than the housing to reduce wear of the housing.
