Abstract: A robot system includes: a robot control unit that controls an operation of a robot, using a control parameter for the robot; a safety monitoring unit that monitors the operation of the robot, using a safety monitoring parameter for the robot; a control parameter setting unit that sets the control parameter to the robot control unit; and a safety monitoring parameter setting unit that acquires the control parameter set to the robot control unit, from the robot control unit, and sets at least one of a plurality of parameters included in the acquired control parameter, as the safety monitoring parameter to the safety monitoring unit.

Abstract: A dustproof type connector comprising a male member 41 having male contact pins 42 and one recess or projection 43 on the internal surface thereof, a female member 44 having a dustproof packing stopper cap 46 on the top thereof, having female contacts 45 which are connected with the male contact pins 42 and which are connected with a pull-out cable which penetrates the dustproof packing stopper cap 46, and having one projection or recess 47 on the external surface thereof to link with the projection or recess 43 of the male member 41, and a dustproof packing 48 having the internal diameter slightly larger than the external diameter of the male member 41 and the external diameter larger than the external diameter of the dustproof packing stopper cap 46, and a dustproof type encoder which employs the dustproof connenctor of this invention.

Abstract: The present invention is directed to a rotary code disk mounting structure for an optical encoder. A rotary code disk (3) with no center hole is fastened to a spindle (2) by an adhesive (J) that a is put in a recess (21) formed in a mounting surface (20). The mounting surface (20) is formed on the top surface of the spindle (2) with the central portion of the backside of the rotary code disk (3) in contact with the mounting surface (20). The rotary code disk mounting structure is applied to optical encoders for use in combination with servometers, machine tools and measuring apparatuses.

Abstract: When a shape of each increment type slit group is a rectangle in a pulse encoder having a plurality of absolute type slits (24, 26, 28, 30) and a plurality of increment type slit groups (14, 16, 18, 20), the plurality of increment type slit groups and the plurality of absolute type slits cannot be irradiated by a single light emitting diode (46). To solve this problem, each increment type slit group is formed in a fan shape and disposed radially around an optical axis (13) of the single light emitting diode (46), so that the absolute type slits (24, 26, 28, 30) can be disposed at the remaining portion of a region (12) irradiated by the single light emitting diode (46). Consequently, a low cost compact pulse encoder can be provided.
