Patent number: 6752758Abstract: An operational remote controller integrates a joystick for bending a bending portion of an inserted portion in an endoscope. A bending lever stands on the joystick. For every automatically returning of the bending lever to a neutral position, a CPU of the operational remote controller detects the neutral position and sets an insensitive band within a predetermined range of the neutral position. Thus, the insensitive band can be set within a relatively narrow range irrespective of variation of neutral positions. The CPU supplies positional information of the bending lever to a control circuit for controlling a motor drive circuit. The control circuit controls a motor drive circuit based on the supplied positional information, and the motor drive circuit drives a motor to bend the bending portion of the inserted portion.Type: GrantFiled: April 15, 2003Date of Patent: June 22, 2004Assignee: Olympus CorporationInventors: Nobuyuki Motoki, Mitsunobu Ono, Takakazu Ishigami, Hiroyuki Fukuda, Yoshihiro Hayashi, Kenji Murakami, Yasufumi Shimoe

Patent number: 5734920Abstract: A compact input/output processing IC, which reduces the CPU load, to which microcomputer 100, input/output processing IC 200, and various inputs and outputs are connected. Parallel signals are connected to a high-speed input/output buffer and serial signals are connected from communications control circuit 207 via serial communications circuit 206 to SIO 104. To achieve the proper control, data requiring high speed is handled by parallel communications. Serial communications is handled by shift registers, first bit of each being connected to the last bit of the other, to form a loop, with instruction and input/output data from the CPU exchanged simultaneously, thereby achieving efficient processing. This achieves better organization of the communications for input/output processing, enabling both better control and a compact hardware design.Type: GrantFiled: January 10, 1997Date of Patent: March 31, 1998Assignee: Nippondenso Co., Ltd.Inventors: Yoshinori Gotoh, Kenji Murakami, Tadashi Shibata, Shunji Kamei, Hajime Nomura
