  • Patent number: 7232853
    Abstract: Colored fine particulate resins can each be produced by bringing a colored resin, which comprises a thermally fusible resin and a colorant evenly distributed in the thermally fusible resin, into a molten state; forming the colored resin, which is in the molten state, into droplet-shaped fine particles in a non-dissolving medium which does not dissolve the colored resin; and then cooling and solidifying the droplet-shaped fine particles. The colored fine particulate resins are useful in image recording materials, printing materials and paints. Articles can be colored with the image recording materials, printing materials or paints.
    Type: Grant

  • Patent number: 6893215
    Abstract: The division wall is made up of a plurality of division wall sections forming a passage wall of high temperature gas which are connected in the direction of arrangement of blades to form a wall surface having a roughly circular cross section as a whole, a gas flow restricting structure for preventing high temperature gas from passing through a gap formed at a connecting portion between the division wall sections in the flow direction of the high temperature gas from the opening on the upstream side of the high temperature gas in the gap, or a gas flow restricting structure for preventing the high temperature gas from being embraced in the gap, for example, a sealing member formed into a prism having a T-shape cross section as a whole composed of a plane portion as a sealing portion and a projected portion for filling the gap is provided.

  • Patent number: 6811373
    Abstract: The present invention provides a turbine moving blade, a turbine stationary blade, and a turbine split ring which are capable of restraining the deterioration and peeling-off of a thermal barrier coating easily and surely, and a gas turbine capable of enhancing the energy efficiency by increasing the temperature of combustion gas. The turbine moving blade provided in a turbine constituting the gas turbine includes a platform having a gas path surface extending in the combustion gas flow direction, and a blade portion erecting on the platform. The thermal barrier coating covering the gas path surface is formed so as to go around from the gas path surface to an upstream-side end face and a downstream-side end face of the outer peripheral faces of the platform.
