Publication number: 20100016666Abstract: An endoscopic system includes a surgical instrument position control apparatus. The surgical instrument position control apparatus estimates motion of an endoscope main body with respect to a target site, based on an image picked up in conjunction with movement of an endoscope. To determine the moving amount of the surgical instrument, the surgical instrument position control apparatus calculates the amounts of operations, such as bending, rotation, and forward and backward movements, of each joint of a surgical arm section which amounts are required to move the surgical instrument from a position taken by the surgical instrument after movement of the endoscope to a surgical procedure position. The surgical instrument position control apparatus thus bends each joint to move the surgical section to the original surgical procedure position so as to hold the position of the surgical instrument every time the endoscope is moved.Type: ApplicationFiled: September 28, 2009Publication date: January 21, 2010Applicant: OLYMPUS MEDICAL SYSTEMS CORP.Inventor: Jun HASEGAWA

Publication number: 20090299575Abstract: An electric power steering (EPS) apparatus 1 includes a motor 12, an EPS actuator 10, a torque sensor 14, and an ECU 11. The EPS actuator 10 uses the motor 12 as a drive source to apply assist force to a steering system, thereby assisting a steering operation. The torque sensor 14 detects a steering torque ? of the steering system. The ECU 11 controls the operation of the EPS actuator 10. Based on the steering torque ? detected by the torque sensor 14, the ECU 11 computes a basic shift amount ?ts_b of the assist force applied to the steering system. The ECU 11 determines which one of returning, holding, and turning is the state of the steering operation. When the state of the steering operation is returning or holding, the ECU 11 executes compensation control for correcting the steering torque ?, which is used in the computation of the basic shift amount ?ts_b of the assist force, thereby increasing the assist force applied to the steering system.Type: ApplicationFiled: June 2, 2009Publication date: December 3, 2009Applicant: JTEKT CorporationInventors: Masayuki KITA, Terutaka Tamaizumi, Akihiko Nishimura, Shinya Aono, Jun Hasegawa, Akira Nambu

Publication number: 20090184105Abstract: A reference heater energization delay time is established according to an engine conditions (shift range, cooling water temperature, intake-air temperature, ambient temperature, and oil temperature) during starting period. An extension delay time is established according to an engine condition after starting period. A final heater energization delay time is established by adding the extension delay time to the reference heater energization delay time. Until an elapsed time after starting period of engine reaches the final heater energization delay time, an energization of a heater of an exhaust gas sensor is inhibited. When the elapsed time after starting period of engine reaches the final heater energization delay time, the energization of the heater is started to heat a sensor element.Type: ApplicationFiled: January 8, 2009Publication date: July 23, 2009Applicant: DENSO CORPORATIONInventor: Jun HASEGAWA
