Publication number: 20080039255Abstract: A working unit includes a gear body disposed forwardly of a tubular member around which a wire is wound and having a rotational axis disposed substantially parallel to the tubular member, and a first gear and a second gear for transmitting rotation of a gear body to another gear body. The numbers of turns of wires, the size of a main shaft, and the size of a gear body, which are positioned forwardly of the tubular member, have no adverse effect on the manner in which a wire is wound around the tubular member. The wire can be wound around the tubular member over a wide region thereof for increasing the angular displacement of the gear body. The increased angular displacement of the gear body makes it possible to increase the angular displacement and rotational torque of the gear body.Type: ApplicationFiled: August 2, 2007Publication date: February 14, 2008Applicants: TERUMO KABUSHIKI KAISHA, KABUSHIKI KAISHA TOSHIBAInventors: Makoto JINNO, Takamitsu Sunaoshi, Shigeru Omori

Patent number: 7295893Abstract: A manipulator operative in a master/slave operative mode includes a master unit commanding an operation; a slave unit having a work unit; a detector detecting the orientation of the master unit and the orientation of the slave unit; and a control device controlling the slave unit in response to a command from the master unit. The control device determines a non-master/slave operative mode or a master/slave operative mode, and calculates a difference between the orientation of the master unit and the orientation of the slave unit. The absolute value of the calculated difference is compared with a preset reference value, and depending upon the result of the comparison, a normal master/slave operative mode or a transitional master/slave operative mode is determined, wherein in the master/slave operative mode, the transitional master/slave operative mode is a transitional mode from the non-master/slave operative mode to the master/slave operative mode.Type: GrantFiled: October 27, 2005Date of Patent: November 13, 2007Assignee: Kabushiki Kaisha ToshibaInventor: Takamitsu Sunaoshi
