  • Patent number: 8512436
    Abstract: There is provided a method for efficiently manufacturing metal nano particles without condensing laser beams by using a lens etc. In this method, first, metallic foil pieces, which are a starting material, are dispersed in a dispersion liquid. Next, laser beams are irradiated directly to the metallic foil pieces without providing a condensing means, by which many metal fine particles are yielded. The particle diameters of the metal fine particles obtained can be controlled to sizes from nano particles to submicron particles by utilizing the relationship between the shape (especially thickness) of the metallic foil piece which is a starting material and the absorbed energy of the laser beam.

  • Patent number: 6799608
    Abstract: There is an object to provide a technique of forming a proper abrasion resistance layer by a thermal spraying and fusing of a self fluxing alloy. The object may be solved by cutting the pipe body along a curved face that is perpendicular to a plane including a central axis of the pipe body and that extends not to cross the inlet hole and the outlet hole but to include a part of the central axis. Thus the pipe body is divided into a first partitioned part having at least one of the inlet hole and the outlet hole, and a second partitioned part. An abrasion resistance layer is then formed on the inner surface of at least the outer bent portion of the pipe body by a thermal spraying and fusing of a self fluxing alloy. Thereafter, the first partitioned part is fitted into the second partitioned part for welding to obtain a bent pipe according to the present invention.
