  • Motorcycle swingarm assembly
    Patent number: 7815005
    Abstract: A swingarm assembly (12) for use in motorcycles for supporting a motorcycle rear wheel (13) includes left and right arms (23L, 23R) and a connecting member (24) by which the left and right arms (23L, 23R) are connected together. At least the arms (23L, 23R) are products of magnesium alloy that are formed by an extrusion technique or a drawing technique.

  • Method of manufacturing gas turbine part using porous metal
    Publication number: 20040168786
    Abstract: A method of manufacturing a gas turbine part including a member having fluid transmission paths therein utilized as a cooling/heat insulating structure, includes the steps of: melting a metal under pressurization of an atmospheric gas; dissolving a gas in the molten metal; and solidifying the metal to thereby manufacture the member including a porous metal having thus created pores. The pores of the porous metal are arranged as a plurality of through pores and/or closed pores, each of which is formed in an substantially linear shape by controlling an angle of a solid-liquid interface in solidification with respect to a plane perpendicular to a traveling direction of the solid-liquid interface which is a determination factor of a pore growing direction.
