  • Publication number: 20200180024
    Abstract: In this invention, a copper powder to which phosphorus (P) is added is developed such that a high-density laminated and shaped product can be obtained by a laminating and shaping method using a fiber laser as a heat source by appropriately reducing the electrical conductivity of copper, so a laminated and shaped product having a high density and a high electrical conductivity can be obtained. This invention is a copper powder for lamination shaping in which a phosphorus element is added to pure copper. The copper powder desirably contains 0.01 wt % or more of the phosphorus element. The copper powder more desirably contains 0.04 wt % or more of the phosphorus element. The copper powder desirably contains 0.30 wt % or less of the phosphorus element. The copper powder more desirably contains 0.24 wt % or less of the phosphorus element. No element other than the phosphorus element is desirably added to the copper powder.

  • Publication number: 20200147682
    Abstract: This invention provides a copper powder to which tin (Sn) is added such that a high-density laminated and shaped product can be obtained by a laminating and shaping method using a fiber laser as a heat source by appropriately reducing the electrical conductivity of copper, so a laminated and shaped product having a high density and a high electrical conductivity can be obtained. That is, this invention provides a copper powder for lamination shaping in which a tin element is added to pure copper. Desirably, the copper powder contains 0.5 wt % or more of the tin element. More desirably, the copper powder contains 5.0 wt % or more of the tin element. When the product has an electrical conductivity sufficient as a copper product, the copper powder desirably contains 6.0 wt % or less of the tin element. Furthermore, no element other than the tin element is desirably added to the copper powder.

  • Patent number: 9140445
    Abstract: A superheated steam generator, capable of generating superheated steam which exceeds about 400° C. even if a litz wire is adopted as an induction heating coil, is generally described. The generator may include induction heating elements that can generate heat by electromagnetic induction and that are housed in a heat-resistant container. The generator may also include a hose that allows cooling water to pass therethrough and which is wound around an outer peripheral surface of the heat-resistant container. A water supply unit for the cooling water is connected to one end of the hose, and the other end of the hose is connected to a steam inlet of the heat-resistant container. An induction heating coil is mounted on an outer peripheral surface of the hose, and a high-frequency power supply unit is connected to the induction heating coil.

  • Patent number: 8109831
    Abstract: An object of the present invention is to provide a game server that can simulate the sensation of competing in a game against an actually existing specific person. The game server of the present invention offers a plurality of options for the actions that gamer A can select in game scenes that change along with the progress of a soccer game. The options include dribble (long), dribble (short), pass in front of the player, pass to the foot of the player, wait, and shoot. The action patterns of gamer A are stored for each game scene by counting the number of times each option is selected. The game server refers to the stored action patterns when playing against another gamer B. This configuration makes it possible for the gamer B to have a virtual experience as if he were competing with the gamer A.
