Abstract: A system for transferring semiconductor workpieces from a load lock to an orientation station and on to a platen is disclosed. The system comprises two load locks, two robots, and one orientation station. Each robot is associated with a respective load lock and follows a fixed sequence. The robot returns a processed workpiece to the load lock and also removes an unprocessed workpiece. The robot then moved to the orientation station, where it removes an aligned workpiece from the orientation station and deposits the unprocessed workpiece on the orientation station. Next, the robot moves to the platen, where it removes a processed workpiece and deposits the aligned workpiece. The robot then returns to the load lock and repeats this sequence.

Abstract: A system for transferring semiconductor workpieces from a load lock to an orientation station and onto a platen is disclosed. The system comprises two load locks, a multi-workpiece orientation station, two multi-pick robots that transfer a plurality of workpieces between a respective load lock and the multi-workpiece orientation station, and two backend robots that transfer individual workpieces between the multi-workpiece orientation station and the platen.

Abstract: The invention comprises a vehicular wide turn warning device having a placard with a warning printed thereon. The placard also has mounted thereon a strobe lamp and a plurality of light-emitting mechanisms, the light-emitting mechanisms being arranged to form an arrow having a point and a tail. The invention also comprises a control circuit for operating the light-emitting mechanisms and strobe lamp mounted upon the placard. The control circuit is arranged such that the light-emitting mechanisms forming the arrow are sequentially and cyclically illuminated beginning with the light-emitting mechanisms forming the tail of the arrow and preceding to the light-emitting mechanisms forming the head of the arrow. The strobe lamp is cyclically illuminated in conjunction with the light-emitting mechanisms forming the arrow. A manually operable switching means located adjacent a driver of a vehicle activates a control circuit for the vehicular wide turn warning device.
