Patent number: 8038914Abstract: In a method for producing a molded article having a resin part, the resin part is injection-molded to an opening of a main body part and the molded article has an excellent air-tightness between the resin part and the main body part. A foam sealant is attached to a peripheral portion around the opening of the main body part. Attached to the main body part is a retainer made of the same kind of resin as injected resin and adapted to keep the foam sealant compressed in its thickness direction. The main body part is placed within a mold so that the retainer is exposed inside a cavity of the mold. A molten resin is injected into the cavity of the mold. The injected resin and the retainer are integrated into the resin part.Type: GrantFiled: November 6, 2006Date of Patent: October 18, 2011Assignees: Toyota Jidosha Kabushiki Kaisha, Matsuo Industries Inc.Inventors: Yoshikazu Suzuki, Tomokiyo Suzuki, Hironao Hayashi, Osamu Kuriyagawa, Iori Kobayashi, Kensuke Nakanishi, Toru Takahashi, Yuki Yamakawa, Masanori Sumida

Patent number: 7824194Abstract: A case with a connector integrally formed with a resin connector, and can be manufactured with a small number of processes is provided. The connector case includes a housing, a resin connector, and a ground terminal extending along an outer periphery of the connector. A terminal-side fixing portion extending backward from the ground terminal is crimped to or pressed over a housing-side fixing portion. When molds are closed after the housing and the ground terminal are placed in the molds for injection molding of the resin connector, a pressing portion formed on the mold presses the terminal-side fixing portion against the housing-side fixing portion to crimp or press the terminal-side fixing portion to or over the housing-side fixing portion. As a result, in the process for the injection molding of the connector, the ground terminal is fixed to the housing at the same time. The connector case with the ground terminal fixed to the housing can be manufactured in a small number of processes.Type: GrantFiled: March 1, 2007Date of Patent: November 2, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Matsuo Industries, Inc.Inventors: Yoshikazu Suzuki, Akira Ishimaru, Tomokiyo Suzuki, Hironao Hayashi, Shigeru Hayashida, Osamu Kuriyagawa, Iori Kobayashi, Kensuke Nakanishi, Toru Takahashi, Yuki Yamakawa, Masanori Sumida

Publication number: 20100159449Abstract: To measure a receptor-mediated increase in intracellular calcium concentration, use is made of a calcium-responding luminescent protein localized in the cytoplasm or mitochondria and a reporter gene having a promoter responding to the second messenger in cells and Renilla-origin luciferase attached to the downstream thereof. By using a coelenterazine derivative, which can exist in the cells in a stable state over a long time, as the substrate of these proteins, a transient increase in the intracellular calcium concentration observed within several seconds is measured by using the calcium-responding luminescent protein. Subsequently, the cells are allowed to survive and cultured for several hours as such without adding a fresh substrate. During this period, an increase/decrease in the gene expression is continuously monitored by the reporter assay method and it is measured and evaluated, if necessary, whether or not the inhibition of the activity is caused by cytotoxicity.Type: ApplicationFiled: May 28, 2007Publication date: June 24, 2010Applicant: NOACELL SCIENCE CO., LTD.Inventors: Mitsuru Iida, Naohiro Araki, Hisatoshi Yabushita, Yoshikazu Suzuki
