  • Patent number: 8518529
    Abstract: The present invention provides a method for manufacturing a woody resin molded body which comprises a step of passing a woody resin composition containing a thermoplastic resin, a cellulose powder and a blowing agent, a weight ratio of the thermoplastic resin to the cellulose powder being from 20/80 to 80/20, through a shaping die that has no core body and extruding the woody resin composition into a cooling die. A barrel temperature of an extrusion molding machine is set lower than a foaming temperature of the blowing agent, and a temperature of the shaping die is set within a foaming temperature range of the blowing agent, to thereby obtain a woody resin molded body which has a high-expanded foam layer and a low-expanded foam layer formed on the outside of the high-expanded foam layer and in which the cellulose powder is not exposed on a surface of the low-expanded foam layer.

  • Publication number: 20130095404
    Abstract: The fuel cell system of the present invention supplies oxidant gas to a fuel cell during periods where generation of electrical power by the fuel cell is stopped. As a result, an amount of oxidant gas that is just sufficient to continue a reaction with remaining fuel gas is continued even when generation of electrical power itself is stopped. It is therefore possible to protect electrolyte membranes from damage occurring as a result of oxygen deficiency. Further, in addition to intermittent operation, the fuel cell system of the present invention is also applicable to steps for the stopping of generation of electrical power by a fuel cell in accordance with other conditions or at the time of the complete stopping of operation of the fuel cell system.

  • Patent number: 8074139
    Abstract: A request change unit outputs a command as a request under control of a judgment control unit. A response condition determination unit determines a condition that is to be matched by a correct response which is to be returned from the other device-in-communication in reply to the command if the other device-in-communication operates in conformity with a protocol. A check unit checks a response received from the other device-in-communication in reply to the command, against the condition. If the received response does not match the condition but is correctable to match the condition as a result of the check, a response correction unit corrects the received response to match the condition under control of the judgment control unit.
