  • Patent number: 9533349
    Abstract: Provided is a highly versatile casting mold in which weight and manufacturing cost can be reduced, and whereby flash can be suppressed. A plate-shaped base part having a flat attachment face to which a back face of a fixed-cavity mold is attached is provided to a fixed mold constituting a casting mold. A portion of the base part in contact with the back face of the fixed-cavity mold has an attachment part body for supporting the fixed-cavity mold, and a pressure increasing means for increasing the pressure imparted to the fixed-cavity mold via the attachment part body in a state in which the mold is closed.
    Type: Grant
    Filed: April 2, 2014
    Date of Patent: January 3, 2017
    Assignee: HONDA MOTOR CO., LTD.
    Inventors: Kunihiro Yokoyama, Hiroshi Matsushita, Takayuki Higashi, Hiromi Fujita, Masanori Masubuchi, Kenichi Katahira, Yoshinori Kubo, Takanori Niwa

  • Patent number: 7824818
    Abstract: In a fuel cell stack that is made by stacking unit cells in alternation with separators, lower edges of collector members that are in contact with oxygen electrodes of the unit cells project downward, providing projecting portions that project below lower edges of frames. Water-repellent regions are provided on lower edges of the projecting portions, facilitating shedding of water from the projecting portions.

  • Patent number: 6544469
    Abstract: An apparatus for producing a metal formed product comprises a molten metal-holding furnace; a semisolidified metal-producing mechanism; a cooling member-restoring mechanism arranged adjacent to the semisolidified metal-producing mechanism, for applying a restoring treatment so that chillers have a desired function; a forming machine for forming semisolidified metal to have a predetermined shape; and an articulated robot capable of transporting a crucible to the molten metal-holding furnace, the semisolidified metal-producing mechanism, and the forming machine. The semisolidified metal-producing mechanism includes first to third agitators. The cooling member-restoring mechanism includes first to third treating sections. These components are arranged in a direction of back and forth movement of the articulated robot. Accordingly, it is possible to efficiently obtain the metal formed product having a high quality.
