Publication number: 20120258988Abstract: A therapeutic or prophylactic agent for diabetes includes a thiazolidine derivative as a PPAR-? agonist as an effective component which exhibits a reduced side effect of the PPAR-? agonist. The therapeutic or prophylactic agent for diabetes includes a particular IP agonist such as beraprost sodium (BPS), and a thiazolidine derivative such as pioglitazone or a pharmaceutically acceptable salt thereof. Since the therapeutic or prophylactic agent exhibits a sufficiently effective hypoglycemic action without being accompanied by side effects characteristic to PPAR-? agonists, the agent is useful as a highly safe and effective therapeutic or prophylactic agent for diabetes.Type: ApplicationFiled: November 12, 2010Publication date: October 11, 2012Applicants: THE UNIVERSITY OF TOKYO, TORAY INDUSTRIES, INC.Inventors: Takehiro Takahashi, Hiroki Kumagai, Takashi Kadowaki, Naoto Kubota, Tetsuya Kubota

Patent number: 7925382Abstract: An input unit enters angular displacements by which drive shafts of a robot arm are to be turned as teaching data into a control unit. The control unit converts the input angular displacements into position-attitude data, namely, converted commands, indicating a position of the free end of the robot arm and an attitude of the robot in a rectangular coordinate system through forward conversion. The control unit corrects the position-attitude data on the basis of inherent errors in the robot to provide corrected position-attitude data. The control unit converts the corrected position-attitude data into corrected angular displacements through inverse conversion and gives the corrected angular displacements to an actuator included in the robot. The inherent errors in the robot include mechanismic errors resulting from machining errors and assembling errors, installation errors and errors in the origins of axes.Type: GrantFiled: December 6, 2005Date of Patent: April 12, 2011Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Tetsuya Kubota, Jun Fujimori, Naoyuki Matsumoto, Tetsuhiko Nishimura

Patent number: 7235947Abstract: A desired q-axis current is determined based on a desired torque, and a desired d-axis current is determined based on the rotating speed of a synchronous motor when the terminal voltage of the synchronous motor coincides with a predetermined maximum permissible voltage to weaken a magnetic field created by the synchronous motor equivalently and to prevent the drop of the output torque of the synchronous motor. The desired d-axis current is determined based on the desired torque and the rotating speed. Therefore, the desired d-axis current can be reduced when a high torque is not necessary and undesired increase of the desired d-axis current can be prevented. Thus the synchronous motor operates efficiently, heat generation of the synchronous motor is prevented and power factor is improved.Type: GrantFiled: November 22, 2005Date of Patent: June 26, 2007Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Hideki Tanaka, Shinji Kajihara, Tsuyoshi Maehara, Tetsuya Kubota

Patent number: 6657156Abstract: A weld portion detector (20) and a laser beam projector (10) disposed a predetermined distance behind the weld portion detector (20) are moved together. The weld portion detector (20) detects a weld line and the laser beam projector (10) projects on the weld line detected by the weld portion detector (20) for laser welding. Pieces of data on weld positions sequentially detected by the weld portion detector (20) are stored sequentially in combination with times when the pieces of data on the weld positions are obtained and moving speeds of the weld portion detector (20) in a memory. A time when the weld portion detector (20) passed a point at which the laser beam projector (10) has just arrived is calculated on the basis of the times and the moving speeds stored in the memory. The laser beam projector (10) projects a laser beam on a weld position detected at the thus calculated time.Type: GrantFiled: December 18, 2001Date of Patent: December 2, 2003Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Tetsuya Kubota, Yoshimitsu Kurosaki, Eiichi Yagi, Tomoyuki Uno, Hirotaka Uehara, Osamu Satoh, Shigekazu Shikoda, Takayuki Murata, Mamoru Nishio
