Patents by Inventor Tsunehiro Mimura

Tsunehiro Mimura has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10032537
    Abstract: A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. When the matrix of the thin plate is crystal-structure metal, the plate can be formed at room temperature, and when the matrix is metallic glass, the plate can be formed in a supercooled liquid state. Therefore the plate can be finished into a separator with an intended shape.

  • Patent number: 9959950
    Abstract: [Problem] To prepare a thin plate having excellent corrosion resistance, conductivity, and formability at low cost. [Solution] A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. An obtained thin plate has a conductive material component that exists, without dissolving, in a metal matrix exhibiting corrosion resistance by passivation, thereby having aforementioned characteristics.

  • Patent number: 9382604
    Abstract: An apparatus for forming an amorphous coating film by jetting flame containing particles of a flame spray material from a flame spray gun toward a base material, causing the particles to be melted by the flame, and cooling both the particles and the flame with the means of a cooling gas before they reach the base material. The apparatus includes a tubular member provided among the path along which the flame is jetted that it surrounds the flame passing through a melting zone in which the particles are melted. The tubular member has a flow channel for the cooling gas, formed along and integrally to the tubular member.

  • Publication number: 20150111132
    Abstract: [Problem] To prepare a metallic separator for PEFCs having excellent corrosion resistance, conductivity, and formability at low cost. [Solution] A thin plate is prepared by an ultraquenching transition control injector with a mixture of a metal powder having corrosion resistance to form a matrix and a powder having conductivity, as a raw material. When the matrix of the thin plate is crystal-structure metal, the plate can be formed at room temperature, and when the matrix is metallic glass, the plate can be formed in a supercooled liquid state.

  • Publication number: 20130263973
    Abstract: [Problem] To prepare an amorphous alloy as an authentic industrial-use material with a wide range of applications by solving various problems such as delayed fracture and ductility. [Solution] The alloy includes 63 at % or more of Ni and consists only of, as a semimetal for amorphization, other than P. The semimetal may include, for example, 10 to 25 at % of B and one or more of Cr, Mo, and Nb as remaining main elements.
