    • A vane pump comprising a cylindrical pump chamber, vanes adapted to rotate within the pump chamber, and a drive rotor arranged eccentrically with respect to the center of rotation of the vanes, such vane pump being formed with through holes in portions of opposite end walls of the drive rotor which are in spaced juxtaposed relationship with side end faces of each vane, such through holes being connected to a line for supplying therethrough a portion of the fluid discharged by the vane pump. During operation of the vane pump, the portion of the fluid discharged by the pump and supplied through the line is ejected through the through openings against the side end faces of the vanes so as to avoid collision between the end walls of the drive rotor and the side end faces of the vanes whereby the service life of the vane pump can be increased.
    • 一种叶片泵,包括圆柱形泵室,适于在泵室内旋转的叶片以及相对于叶片旋转中心偏心设置的驱动转子,该叶片泵在相对端壁的相对端壁的部分中形成有通孔 所述驱动转子与每个叶片的侧端面间隔开并置关系,所述通孔连接到用于通过叶片泵排出的流体的一部分供给的管线。 在叶片泵的操作期间,由泵排出并通过管线供应的流体的部分通过通孔被喷射抵靠叶片的侧端面,以避免驱动转子的端壁与 叶片的侧端面,从而可以增加叶片泵的使用寿命。

    • In an electron beam exposure system controlled by a computer, the system includes: an electron optical device for generating electron beams and irradiating the beams to a sample on a stage through a plurality of electron lens, a main deflection coil, and sub deflection electrodes, to form predetermined circuit patterns on the sample. The system also includes a position control device controlling the driving of the stage based on a stage position coordinate designated by the computer, detecting an actual stage position coordinate, and calculating an error value between the designated stage position coordinate and the actual stage position coordinate, the error value being divided into two components of an upper bits portion having an relatively large error value and a lower bits portion having a relatively small error value, and a deflection control device controlling the direction of the electron beams based on the main pattern data corrected by the upper bits portion and the sub pattern data corrected by the lower bits portion, and based on selected main and sub wait times determined by exposure and non-exposure timings.

    • A slide vane type compressor comprises a cam ring formed with at least one working chamber and a rotor arranged in the at least one working chamber with an outer peripheral surface of the rotor being disposed close to an inner wall surface of the cam ring at least at one axial sealing portion thereof, with the rotor being formed vane grooves for respectively accommodating a plurality of vanes. At least one suction port introduces gas into the at least one working chamber, with the suction port having a suction terminal point angle extending from the axial sealing portion to a terminal point of the suction port, as viewed in the direction of rotation of the rotor. The suction terminal point angle of the suction port is greater than a geometrical suction terminal point angle geometrically determined in dependence upon the number of working chambers and the number of the plurality of vanes so that the suction terminal point angle of the suction port is advanced as compared with the geometrical suction terminal point angle.
