  • Pipe unit with connector and producing method thereof
    Publication number: 20060208479
    Abstract: A pipe unit (100) with a connector (120), and a producing method thereof, are disclosed. The pipe unit (100) includes the tabular connector (120) having at least a through hole (121) into which the end portion of a corresponding pipe member (110) is inserted. The end portion of the pipe member (110) is increased in diameter and thereby caulked on the inner surface of the through hole (121). The pipe member (110) includes an enlarged portion (111) with the diameter thereof increased and a non-enlarged portion (112) with the diameter thereof not increased, which are connected to each other by a stepped portion (113) formed outside the connector (120). The thickness of the connector (120) and the machining cost of the through hole (121) are reduced.

  • Resin molded articles and method of manufacturing the same
    Publication number: 20050285294
    Abstract: In a method of manufacturing a resin molded article, resin including a foaming agent is injected into a cavity defined in a mold assembly. Then, a movable mold of the mold assembly is moved to partly expand the cavity so that the foaming is promoted at the part where the cavity is expanded. Therefore, a high foamed portion having voids therein and a low foamed portion having an expansion ratio less than that of the high foamed portion are integrally formed in the resin molded article.
