    Abstract: An impact absorbing mechanism for absorbing impact generated upon meshing of gears by starting or stopping an electric motor, for example, in a speed reduction gear train of a disk grinder, has the problem that its ease of manufacture and the durability are lowered because small elastic components are located between a driven gear and a driven shaft when an impact absorbing action occurs in the rotational direction in the related art. The present invention is aimed to improve the ease of manufacture and the durability of the impact absorbing mechanism. It is configured to absorb impact by displacing steel balls in a diameter expanding direction by relative rotation of a driven gear and a driven shaft due to rotational power generated upon meshing and by displacing an axial displacement member in an axial direction against an axial elastic member.

    Abstract: A control system for precision machine tools and similar devices provides a precise position during active operations on a table supported workpiece or part. The present system provides a support table on which a machine part or specimen is mounted that is controlled in its position through a friction free spring type hinge relative to a base, and which is held therein with a piezoelectric actuator operated in an active closed loop system to maintain a set position without any backlash.
