  • Publication number: 20110287201
    Abstract: What is offered is: a polyarylene sulfide resin composition which includes 100 mass parts of a polyarylene sulfide resin (A), 0.1 to 8 mass parts of a metal fine particle (B) containing at least one metal species selected from the group consisting of copper, nickel, and zinc, and 0.1 to 5 mass parts of a thermoplastic elastomer (C); and a piping member for fluid obtained by molding of the pertinent resin composition. This piping member for fluid is useful for water-supply pipes, water-heater pipes, and the like in cold weather climates, as it is high in toughness at low-temperature, inhibits damage or rupture of pipes due to freezing, and also inhibits occurrence of creep deformation at high temperature.

  • Patent number: 6752906
    Abstract: A loudspeaker in which the input resistance is improved and the effect of humidity on the playback frequency response is suppressed, and a method for the preparation of the loudspeaker. A sheet-like product, containing glass particles with a particle size of 8 nm to 300 nm and polyamide resin, and prepared by application of a paper-making technique, is used as the diaphragm. The content of the glass particles in the compound material is 5 weight % to 70 weight %. In preparing the diaphragm, a phase of an aqueous solution containing diamine and water glass is contacted with a phase of an organic solution containing a dicarboxylic acid halide to generate a compound material containing glass particles and the polyamide resin. The compound material so prepared is formed into a sheet by a paper-making technique. In the process of the preparation by the paper-making technique, the compound material mixed with other fibrous material may also be used as a starting material.
