Publication number: 20140304988Abstract: In a method for manufacturing a channel-type brush seal of an embodiment, a cored bar is made to abut on a bundle of thin wires and the bundle of thin wires is bent at a part at which the cored bar abuts on the bundle of thin wires. Here, the cored bar is made to abut on the bundle of thin wires so that an extending direction of the thin wires in the bundle of thin wires is inclined with respect to an extending direction of the cored bar, and then the bundle of thin wires is bent, to thereby make extending directions of the bent thin wires intersect. Next, the channel is bent so that the channel sandwiches and fastens the bundle of thin wires and the cored bar at a part at which the bundle of thin wires is bent.Type: ApplicationFiled: April 7, 2014Publication date: October 16, 2014Applicant: Kabushiki Kaisha ToshibaInventors: Tatsuo YAMASHITA, Yuki MIMURA, Yoshifumi IWASAKI

Patent number: 7338138Abstract: A link has link connecting bores (15) and (16) at both ends thereof and a wear rail (13) disposed between the upper portions of the link connecting bores (15) and (16). Portions near the ends of the wear rail (13) are designed to have a hardness smaller than that of a center portion of the wear rail. Accordingly, the portions near the ends of the wear rail can be abraded more easily than the center portion of the wear rail. Since the portions near the ends of the wear rail, in which the portions are easily abraded, are positioned closer to the link connecting bores, abrasion loss in use is smaller than that of the center portion owing to its structure. So, the difference in abrasion amount makes it possible to lower a level irregularity of the wear rail.Type: GrantFiled: August 25, 2005Date of Patent: March 4, 2008Assignee: Komatsu Ltd.Inventors: Tomoyoshi Sho, Tatsuo Yamashita

Patent number: 7194403Abstract: An interface unit issues input/output instructions regarding an input of a translation target sentence, an output of a translated sentence, and a translation control. A machine translating apparatus translates a document in a certain language into a document in another language. A translation memory device translates a sentence by searching an original/translation database in which sentences in a certain language and original/translation sentences in another language corresponding thereto have been accumulated. A data compatible processing unit makes original/translation information translated by the machine translating apparatus and original/translation information translated by the translation memory device common, thereby enabling them to be fetched mutually as original/translation information.Type: GrantFiled: September 28, 2001Date of Patent: March 20, 2007Assignee: Fujitsu LimitedInventors: Seiji Okura, Akira Ushioda, Masaru Fuji, Tatsuo Yamashita

Patent number: 7037892Abstract: This invention relates to a hematopoietic stem cell proliferating agent comprising IGF-I, a hematopoietic stem cell proliferating agent comprising IGF-I and at least one protein selected from among SCF, M-CSF, and G-CSF, and a method of growing hematopoietic stem cells which comprises culturing hematopoietic stem cells in a medium containing IGF-I and at least one protein selected from the group consisting of SCF and M-CSF. The hematopoietic stem cell proliferating agent of the invention causes hematopoietic stem cells to proliferate in the undifferentiated state whether in vivo or in vitro and can, therefore, be used for amelioration of the cytopenia induced by radiotherapy or chemotherapy using anticancer drugs, prevention of infectious diseases associated with lymphopenia, or in vitro culture for multiplication of hematopoietic stem cells and extrasomatic culture of recombinant stem cells in gene therapy.Type: GrantFiled: July 19, 2002Date of Patent: May 2, 2006Assignee: Astellas Pharma Inc.Inventors: Yoshimasa Saito, Yoshiko Ueda, Kouichi Tamura, Yoko Takata, Hisashi Yamada, Tatsuo Yamashita, Masakazu Kobayashi

Patent number: 6470746Abstract: An object of the present invention is to obtain an acceleration sensor that can reliably detect acceleration when inclination of an inclining member is within a fixed range, and that can reduce unnecessary movement of relevant members when inclination of the inclining member is outside of the range, so that space efficiency in an inner portion is high. In the present invention, a gear of a fixed gear fixed at a seat cushion is formed in only a portion in the circumferential direction, and a portion at which the gear is not formed is a sliding surface. One of teeth among a plurality of teeth of a pinion of a revolving gear is short, to form a notched tooth portion. In a state in which the forward-collapsed angle of a seatback exceeds a predetermined angle, the notched tooth portion faces the sliding surface and the revolving gear body no longer rotates. At this time, since a bracket at which a sensor ball is mounted also does not rotate, the bracket is held at a fixed position relative to a frame plate.Type: GrantFiled: November 29, 2000Date of Patent: October 29, 2002Assignee: Kabushiki Kaish Tokai-Rika-Denki-SeisakushoInventors: Yasunori Murayama, Tomonori Nagata, Keiichi Kato, Tatsuo Yamashita, Seiji Hori, Keisuke Imai, Yoshio Umezawa
