Title: Variable light attenuator
Inventor: BEENAADO JIYOOJI KIYARON
IPC: G02B6/00
Filed: 1993-03-30
Abstract: PURPOSE: To obtain a variable light attenuation device which can control the attenuation quantity of light intensity continuously and is small in size and inexpensive by deforming an optical fiber from a nearly circular state to a non-circular state and controlling the attenuation quantity of light passing through an optical fiber. CONSTITUTION: A support member 20 is composed of a thin steel-made tape 23 and a horseshoe type spring 15 and is flexible. The optical fiber 24 which is supported nearly circularly by the support member 20 is deformed by a control means from the nearly circular state to the noncircular shape. At this deformed part, the light propagated in the optical fiber 24 is attenuated. Further, precise control is performed so that the radius of curvature of the optical fiber 24 supported while curved nearly circularly is smaller than a predetermined limit value. Then the optical fiber 24 also deforms, so the light of the fiber core is leaked out without breaking or deteriorating the optical fiber 24 or a signal passing through the optical fiber 24, thereby attenuating the light propagates in the optical fiber 24.

Title: Stopper device for industrial robot
Inventor: GO CHANSHO
IPC: F16P7/02
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To provide electrical and mechanical stop mechanism in a single support body by including a limit switch for suspending driving of a driving means in response to the movement of a movable stopper element. SOLUTION: In case of malfunction of a control part and a driving motor being generated, a movable member and a stop member are relatively rotated exceeding a specified software operating range. When a fixed stopper element 22 presses a second arm 28 of a movable stopper element 23, the movable stopper element 23 is rotated around a pivot pin 24. At this time, a limit switch 41 instantaneously senses the rotation of the movable stopper element 23 through a contact part 43 coming in face contact with the profile of an action part 26 of the movable stopper element 23, and outputs a signal to the driving motor to stop the rotating part of the driving motor. The relative rotation of the movable member to the stop member is therefore stopped by electrical stop operation of the limit switch 41.
