    Patent number: 4964503
    Abstract: A manipulator features the use of a single motor and a plurality of flexible cables which are interconnected with the motor via a plurality of clutches which can be selectively engaged and disengaged. The cables transmit rotational energy to elements of the manipulator via translation devices which convert the rotational motion into linear motion.

  • Clutch cover assembly with annular coned disc spring
    Patent number: 4949829
    Abstract: In a clutch cover assembly including a diaphragm spring and a coned disc spring, circumferential plural places of the coned disc spring are secured to projecting portions provided on a clutch cover in such a manner as leaving no play at least in a circumferential or axial direction. Since there is no clearance between secured portions of the coned disc spring and projecting portions of the clutch cover, the coned disc spring can be prevented from emitting abnormal sound due to its axial or circumferential vibration.

  • Method of detecting the position of an object
    Patent number: 4880307
    Abstract: In a position detection system when a preselected parameter magnitude of a signal produced in response to a received reflected laser beam, is excessively high, the power of the laser is reduced until such a satisfactory level is reached. On the other hand when the signal level is low and laser power cannot be increased further, signal amplification is induced until such time as the required level is produced.
