Patent number: 8661867Abstract: In the metal billet to be used for hot dilation forming, a forward side with respect to the pressing direction has a quadrate section and its diagonal length is not more than an inner diameter of a container. Moreover, a backward side with respect to the pressing direction has a circular section and its diameter is substantially same as the inner diameter of the container. The metal billet is heated to a temperature suitable for press working and is set into a container for press forming. While a center of a workpiece of the metal billet is being bored by a boring punch to be operated by a pressing machine, the metal billet is hot-dilated so that a bottomed container for a cask is formed.Type: GrantFiled: May 6, 2008Date of Patent: March 4, 2014Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Yoshihiko Funakoshi, Takeshi Tsunezumi, Naohiro Mizuno, Katsuhiko Tokuno, Chikayuki Matsumoto, Yoshiharu Taura, Shigenori Shirogane, Katsunari Ohsono, Toshihiro Matsuoka

Patent number: 8584923Abstract: An endless hot rolling material shear-joining method capable of threading hot rolling materials in a finish rolling process without strip breakage by controlling joining conditions for the hot rolling materials in an endless hot rolling process for high carbon steel, and an endless hot rolling plant therefor are disclosed. The shear-joining method for endless hot rolling materials of high carbon steel includes shear-joining high carbon steel metal bars comprising, in terms of weight %, 0.30% to 1.20% C, inevitable impurities, and balance Fe, or comprising 0.15% to 1.5% C containing at least one of Cr, Ni, Mo, V, Ti, W, B, Nb, and Sb, inevitable impurities, and balance Fe, such that a joined surface of the joined metal bars is formed to be inclined in a thickness direction of the metal bars, in a hot rolling plant by a joiner adapted to join the metal bars after overlapping tail part of a leading one of the metal bar and top part of a trailing metal bar.Type: GrantFiled: November 20, 2006Date of Patent: November 19, 2013Assignees: POSCO, Mitsubishi-Hitachi MetalsInventors: Jong-Sub Lee, Youn-Hee Kang, Chun-Soo Won, Jong-Bong Lee, Sang-Wook Ha, Kenji Horii, Toshihiro Usugi, Hideaki Furumoto, Shigenori Shirogane, Takao Funamoto

Patent number: 5782960Abstract: A hydrogen separation membrane has a hydrogen-permeable metal foil laminated to a porous metal support. The metal support comprising a laminate of metal-reinforcing plates each having a plurality of hydrogen-flow-through holes. The metal-reinforcing plates have rectangular or similarly shaped holes having longitudinal and lateral axes. The laminate is assembled so that the longitudinal axes of the holes of adjacent metal-reinforcing plates intersect substantially at right angles with each other.Type: GrantFiled: March 17, 1997Date of Patent: July 21, 1998Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Makoto Ogawa, Toshiro Kobayashi, Minoru Sueda, Takahiro Matsumoto, Tetsuya Imai, Shigenori Shirogane, Hiroshi Shiota, Toshiuki Uchida, Shinsuke Ota
