Patent number: 10773267Abstract: PROBLEM: To provide a large device and a method which is advantageous for forming a large-area amorphous film. SOLUTION: A device of the invention sprays a flame including a particulate material with a spraying machine toward a substrate, melts the material with the flame, and cools the material and flame by cooling gas before they reach the substrate to form an amorphous film. The spraying machine has particulate material spraying ports and flame spraying ports such that the flame including the material has an oblong cross section. Inert gas spraying ports are successively placed on both sides across the ports of the material and flame. Mist spraying ports are successively placed on both sides across the ports for the material, flame and inert gas. A skirt is attached/detached depending on a combustion gas or a film width to restrain film width narrowing and increase of film thickness deviation.Type: GrantFiled: January 10, 2013Date of Patent: September 15, 2020Assignee: USUI CO., LTD.Inventors: Ryurou Kurahashi, Hiroshi Matsumoto, Junji Takehara, Yoshihisa Fukutome

Patent number: 10032537Abstract: 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.Type: GrantFiled: May 28, 2013Date of Patent: July 24, 2018Assignees: NAKAYAMA AMORPHOUS CO., LTD., USUI KOKUSAI SANGYO KAISYA, LTD., YAMANAKA ENG. CO., LTD.Inventors: Ryurou Kurahashi, Junji Takehara, Shigeo Kakudou, Tsunehiro Mimura

Patent number: 9959950Abstract: [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.Type: GrantFiled: May 28, 2013Date of Patent: May 1, 2018Assignee: NAKAYAMA AMORPHOUS CO., LTD.Inventors: Manabu Kiuchi, Ryurou Kurahashi, Junji Takehara, Shigeo Kakudou, Tsunehiro Mimura

Patent number: 6216883Abstract: A wafer holding hand of the present invention is constituted so that two fixed clamps (2) and one movable clamp (6) are provided on a finger (1). The movable clamp (6) is supported by a plate spring (8) via a clamp holder (7), and the plate spring (8) is fixed to the slider (9). The slider (9) is driven by an air cylinder (10). The fixed clamp (2) is hook shaped, and the movable clamp (6) is drum shaped. A wafer W is held at three points by the movable clamp (6) and the two fixed clamps (2), and a force is applied to the movable clamp (6) by the plate spring (8) so as to hold the wafer W.Type: GrantFiled: January 6, 2000Date of Patent: April 17, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Tomoyuki Kobayashi, Junji Takehara
