Patent number: 7892789Abstract: There are provided trehalose transporter gene and a method of introducing trehalose into cells by using the gene. Candidates for the trehalose transporter genes were searched in P. vanderplanki EST, resulting in being obtained cDNA designated as Tret1. Tret1 encodes a 504 amino acid protein with 12 trans-membrane structures. Tret1 expression was induced by desiccation stress and predominant in the fat body. Functional expression of TRET1 in Xenopus oocytes showed that transport activity was specific for trehalose and independent of extracellular pH and electrochemical membrane potential. The direction of transport of TRET1 was reversible depending on the concentration gradient of trehalose. Apparent Km and Vmax of TRET1 for trehalose were extraordinarily high values. These results indicate that TRET1 is a facilitated, high-capacity trehalose-specific transporter. Tret1 is widespread in insects. Furthermore, TRET1 conferred trehalose permeability upon cells including those of vertebrates as well as insects.Type: GrantFiled: March 5, 2008Date of Patent: February 22, 2011Inventors: Takahiro Kikawada, Takashi Okuda, Masahiko Watanabe, Ayako Saito, Yasushi Kanamori, Yuichi Nakahara

Publication number: 20060243844Abstract: In an emergency situation, a pretensioner is activated so that a spool and a locking base are quickly rotated together in a belt-retracting direction. Subsequently, a stopper is guided along a guide groove so as to move (rotate) counterclockwise relatively with respect to the locking base, thereby reaching an active position. Accordingly, the stopper is released from a latching claw, and a quick-lock pawl is rotated clockwise with a biasing force of a spring, whereby the latching claw becomes engaged with internal teeth. Thus, the locking base becomes locked so that the locking base is prevented from rotating in the belt-withdrawing direction, and the EA operation by the torsion bar is quickly performed.Type: ApplicationFiled: April 3, 2006Publication date: November 2, 2006Inventors: Noriyuki Kosugi, Koji Hiramatsu, Masahiro Shiotani, Yasushi Kanamori, Miwa Morimoto

Publication number: 20060237569Abstract: A seatbelt retractor including a spool including a first spool component for retracting the seatbelt and a second spool component to which a driving force of a pretensioner is transmitted. When the relative rotational torque reaches a predetermined value or more, a member linking the spool components is subject to bending deformation and tensile deformation so that the first spool component rotates relatively with respect to the second spool component in a belt-withdrawing direction. As a result, the spool rotates in a belt-retracting direction so that a torsion bar becomes twisted, whereby impact energy is absorbed.Type: ApplicationFiled: April 3, 2006Publication date: October 26, 2006Inventors: Noriyuki Kosugi, Koji Hiramatsu, Masahiro Shiotani, Yasushi Kanamori

Patent number: 6761328Abstract: A seat belt retractor including a torsion bar is provided. A second torque transmitting portion of the torsion bar is clamped between a reel and a holder member press-fitted radially in the reel without backlash in the axial direction. A first torque transmitting portion is strictly fixed to a pawl holder without backlash in the axial direction by radially crimping an internal periphery of a left end portion of the pawl holder of a locking means. Therefore, the first and second torque transmitting portions conventionally formed in a torsion bar are effectively used, thereby eliminating a groove for an E-ring as conventionally used and thus simplifying the configuration of the torsion bar. In addition, since the first and second torque transmitting portions can operate without backlash, the occurrence of jarring noise due to vibrations of the seat belt retractor can be prevented.Type: GrantFiled: December 5, 2000Date of Patent: July 13, 2004Assignee: Takata CorporationInventors: Joji Mishina, Yasushi Kanamori, Masahiro Shiotani
