摘要： A screw is incorporated in a heating barrel, and the tail end of the screw is rotatably supported by the front surface of an intermediate plate. Behind the intermediate plate, two linear motor units are connected in parallel and arranged around the shaft of the screw to form axial symmetry. The output shafts of the linear motor units are connected to the tail end of a driving shaft through a common connecting arm, and the leading end of the driving shaft is fixed to the rear surface of the intermediate plate. Each of the liner motor units is constituted by a plurality of voice coil linear motors connected in parallel. Each of the linear motor units can be independently controlled. Voice-coil linear motors to be used are selected according to the type of product to be manufactured.

摘要： A vacuum processing apparatus performs processing such-as a pattern depiction with a charged beam within a process chamber evacuated to a high vacuum by an ion pump. The vacuum processing apparatus, which makes it possible to prevent the accuracy of the charged beam pattern depiction from being deteriorated by ions and electrons leaking from the ion pump, has a conductor and a voltage applying unit. The conductor is arranged in the vicinity of the suction port of the process chamber communicating with the ion pump such that the conductor is electrically insulated from the process chamber. The voltage applying unit imparts a potential differing from that of the process chamber to the conductor. Because of the potential difference between the conductor and the process chamber, the ions and electrons leaking from the ion pump are reflected or adsorbed by the conductor so as to suppress leakage of the ions and electrons into the process chamber.
