Publication number: 20080213754Abstract: The ATP amplification method of the present invention is a method for amplifying and detecting a very trace amount of exogenous ATP by allowing a fusion protein (PPK-ADK) of a polyphosphate kinase and an adenylate kinase, the fusion protein not containing ADP, to act on a mixture of ATP, AMP, and a polyphosphate compound. The present invention also provides an ultrasensitive ATP amplification method by which ATP at a single cell level can be amplified and detected, and an ultrasensitive microbial assay based on this ATP amplification method.Type: ApplicationFiled: July 27, 2004Publication date: September 4, 2008Inventor: Akio Kuroda

Patent number: 6373017Abstract: A continuous hot rolling mill with a metal block conveying apparatus and a metal block joining apparatus which moves with the metal blocks along the metal block conveying apparatus to conform a joining operation. The metal block conveying apparatus uses rollers supported by cylinders with a common hydraulic circuit which allows the cylinders to follow guide rails on the metal block joining apparatus and lower out of the path of the metal block joining apparatus and then return to a metal block support position after the metal block joining apparatus' passage without individual control circuits and valves for each of the cylinders.Type: GrantFiled: October 9, 1999Date of Patent: April 16, 2002Assignees: Kawasaki Steel Corporation, Mitsubishi Jukogyo Kabushiki KaishaInventors: Shigeru Isoyama, Takeshi Hirabayashi, Hideyuki Nikaido, Hirosuke Yamada, Nozomu Tamura, Toshiaki Amagasa, Toshisada Takechi, Katsuhiro Takebayashi, Kanji Hayashi, Kunio Miyamoto, Akio Kuroda, Kazunori Nagai, Yoshiki Mito, Kazuo Morimoto, Kazuya Tsurusaki, Kiyoshi Izumi

Patent number: 6345756Abstract: The invention comprises a continuous hot rolling method in which a rear end portion of a preceding metal block and a fore end portion of a succeeding metal block are cut and the metal blocks are joined to each other by heating and pressing followed by a finish rolling. A region of each metal block is restrained from a clamping position to the end portion thereof in order to prevent a change in level of the metal blocks in heating and pressing the piece. The end portions of the metal blocks can be thus prevented from deformation.Type: GrantFiled: November 15, 1999Date of Patent: February 12, 2002Assignees: Kawasaki Steel Corporation, Mitsubishi Jukogyo Kabushiki KaishaInventors: Shigeru Isoyama, Takeshi Hirabayashi, Hideyuki Nikaido, Hirosuke Yamada, Nozomu Tamura, Toshiaki Amagasa, Toshisada Takechi, Katsuhiro Takebayashi, Kanji Hayashi, Kunio Miyamoto, Akio Kuroda, Kazunori Nagai, Yoshiki Mito, Kazuo Morimoto, Kazuya Tsurusaki, Kiyoshi Izumi

Patent number: 6262402Abstract: According to the invention, the rear end of a preceding metal piece and a front end of a succeeding metal piece are heated, pressed and joined prior to the finishing hot rolling. An alternating magnetic field running through the metal pieces in the thickness direction thereof is generated in an end region on opposed faces of the respective metal pieces to perform heating. Another alternating magnetic field whose direction is reverse with respect to that of the former alternating magnetic field is partially generated in the end region on the opposed faces of the metal pieces and in either a region where the metal pieces exist or a region outside width ends of the metal pieces. This assures a uniform heating of the end region on the opposed faces of the metal pieces over their full width to reliably join the both metal pieces to each other.Type: GrantFiled: July 12, 1999Date of Patent: July 17, 2001Assignee: Kawasaki Steel CorporationInventors: Shigeru Isoyama, Takeshi Hirabayashi, Hideyuki Nikaido, Toshiaki Amagasa, Nozomu Tamura, Takahiro Yamasaki, Masashi Osada, Hirosuke Yamada, Toshisada Takechi, Norio Takashima, Junzo Nitta, Shuji Amanuma, Kanji Hayashi, Akio Kuroda, Yoshiki Mito, Kunio Miyamoto, Kazuo Morimoto, Ikuo Wakamoto, Kazuya Tsurusaki, Hideo Sakamoto, Michio Hashimoto, Hiroyuki Nakano, Toshinobu Eguchi, Fumihiro Maeda

Patent number: 6218649Abstract: Method and apparatus for joining metal pieces using induction heating. Metal pieces to be joined are placed end-to-end with a gap between them and induction heated in the thickness portion. To maximize speed and even heating edge-to-edge of the ends, members of a magnetic substance are provided in a gap between the inductor and the piece to be heated, thereby enhancing local heating effect by increasing magnetic flux density. Once heated, the ends are pressed together end-to-end for joining.Type: GrantFiled: July 12, 1999Date of Patent: April 17, 2001Assignee: Kawasaki Steel CorporationInventors: Shigeru Isoyama, Takeshi Hirabayashi, Hideyuki Nikaido, Toshiaki Amagasa, Nozomu Tamura, Takahiro Yamasaki, Masashi Osada, Hirosuke Yamada, Toshisada Takechi, Norio Takashima, Junzo Nitta, Shuji Amanuma, Kanji Hayashi, Akio Kuroda, Yoshiki Mito, Kunio Miyamoto, Kazuo Morimoto, Ikuo Wakamoto, Kazuya Tsurusaki, Hideo Sakamoto, Michio Hashimoto, Hiroyuki Nakano, Toshinobu Eguchi, Fumihiro Maeda

Patent number: 6184508Abstract: An apparatus for joining metal pieces using induction heating. Preceding and succeeding metal pieces are followed by a carriage which carries an inductor. The inductor has the ability to move in the longitudinal direction of the metal pieces relative to the carriage to allow the inductor to move more or less upon the preceding or succeeding metal pieces to increase or decrease the induction heating effect, thereby taking into account any thickness variation of the metal pieces and yet still heating them evenly with regard to each other, prior to their being pressed against each other for joining before hot finishing rolling.Type: GrantFiled: July 12, 1999Date of Patent: February 6, 2001Inventors: Shigeru Isoyama, Takeshi Hirabayashi, Hideyuki Nikaido, Toshiaki Amagasa, Nozomu Tamura, Takahiro Yamasaki, Masashi Osada, Hirosuke Yamada, Toshisada Takechi, Norio Takashima, Junzo Nitta, Shuji Amanuma, Kanji Hayashi, Akio Kuroda, Yoshiki Mito, Kunio Miyamoto, Kazuo Morimoto, Ikuo Wakamoto, Kazuya Tsurusaki, Hideo Sakamoto, Michio Hashimoto, Hiroyuki Nakano, Toshinobu Eguchi, Fumihiro Maeda
