Abstract: An industrial robot has a servo system allowing higher-speed robot operation than in conventional robots. The servo system includes a movable arm or arms pivotable about a pivot axis or axes and/or movable along an axis or axes. The servo system includes at least one movable arm pivotal about a vertical axis and associated with a servo motor for angular displacement within a substantially horizontal plane. A servo motor for driving the horizontally pivotable movable arm is mounted on a base frame of the robot. By mounting the servo motor on the base frame, the load on the movable arm can be reduced significantly so as to allow the movable arm to be operated at higher speeds. The servo system includes a controller adapted to control robot operation.

Abstract: A window regulator is disclosed wherein when a window pane is slightly lowered from its full-closed uppermost position, the window pane is shifted toward an inner panel of the door, and when the window pane is moved up to the slight-open position from its full-open lowermost position, the window pane is shifted toward an outer panel of the door, so that a so-called "flush surface arrangement" is achieved in a door window construction.

Abstract: Herein disclosed is a window regulator of a sashless door, which comprises a link motion device which can assume both a contracted condition and an expanded condition. When the window pane is moved up near its full-closed uppermost position, the link motion device changes its condition from the contracted condition to the expanded condition thereby shifting the lower portion of the window pane outwardly, that is, toward the outer panel of the door.

Abstract: For use in gas chromatograph, there is provided a specimen capsule which has a sample wrapped in a foil or net of ferromagnetic metal. Also provided is a process for gas chromatography which comprises the steps of placing the specimen capsule in the vaporizer of the gas chromatograph, vaporizing the sample by means of alternative current induction and conducting necessary analysis on the resultant gases.
