  • Patent number: 10487066
    Abstract: In the present invention, a sugar alcohol can be efficiently produced from a cellulose-containing biomass by carrying out a step (1) of filtering an aqueous sugar solution, which is obtained by hydrolysis of a cellulose-containing biomass, by passing the solution through a separation membrane having a molecular cut-off of 300-800 so as to remove catalyst poisons to the non-permeate side and collecting a sugar solution from the permeate side, and a step (2) of subjecting the sugar solution obtained in step (1) to a hydrogenation reaction in the presence of a metal catalyst.

  • Patent number: 10381662
    Abstract: A separator for a fuel cell, to be disposed opposing to a membrane electrode assembly, is provided. The separator includes a separator central area portion opposing to a center area of the membrane electrode assembly that concerns generating power, an outer edge portion located in an outer edge of the separator central area portion, a rubber molded body made of rubber, the rubber molded body being formed in the outer edge portion by die-casting a die-casting rubber material using die, and an adhesive layer formed in the outer edge portion, for adhering the rubber molded body to the outer edge portion. The adhesive layer is formed over an adhesive layer area that includes and is larger than an area where the rubber molded body is die-casted in the outer edge portion. Thus, a disadvantage due to burrs which are generated when die-casting the rubber molded body can be reduced.

  • Patent number: 5865418
    Abstract: A compact fluid control valve effects a reliable fluid flow regulation by the use of a shape memory alloy wire. The valve comprises a barrel provided with a base member and a valve body. The valve body is cooperative with the base member to define therebetween a valve opening in the course of an internal flow path through the valve for a fluid. The valve body is movable towards and away from the base member to vary the valve opening for regulating the flow of the fluid. A bias spring urges the valve body for varying the valve opening in one direction. The shape memory alloy wire connects the valve body to the barrel to move the valve body against the bias spring for varying the valve opening when heated. The barrel has anchor members for securing the ends of the wire.
