Title: Power converter
Inventor: NOKITA AKIHIRO
IPC: H02M7/217
Filed: 1994-11-28
Abstract: PURPOSE:To increase a switching frequency and to make a filter capacitor compact by constituting a power converter of an electrostatic-induction type self-arc-extinguishing element. CONSTITUTION:A one-chip microcomputer 12 converts a voltage command V* into the digital quantity with an AD converter 14. Operation is performed with a PWM pulse operating part 15 so as to obtain the rectification output voltage corresponding to the value of the digital quantity. A rectifier 3, which is controlled with a base driving circuit 13, performs the switching operation with the PWM pulse pattern formed with the one-chip microcomputer 12 and converts the AC power of a three-phase AC power supply 1 into the DC power. A switching element constituting the rectifier 3 is constituted of an insulated- gate bipolar transistor, whose dead-zone time of a self-arc-extinguishing element is short and high-speed switching can be performed. Therefore, the effect of the phase delay caused by the dead-zone time is less, the control system is stably operated even if the control-angle frequency is increased, the decreasing action for the pulsation of the output current is stable and the reliability is improved.

Title: Machining method for ball screw
Inventor: OKAMOTO MASAHIRO
IPC: B23G9/00
Filed: 1988-11-18
Abstract: PURPOSE:To shorten a span of machining time by applying rough grind and fine grind to a ball rolling groove of a ball screw consisting of fragile material such as ceramics or the like by grinding wheel in order, and then heating it by means of a laser beam. CONSTITUTION:In a ceramics ball screw W supported between two centers 23 and 24, a grinding wheel 28 is rotated drived in an arrow B direction, this ball screw W is rotated and driven in an arrow A direction, and a wheel spindle stock 27 is advanced forward for infeed, then a table 13 is moved in an arrow C direction, thus a rolling groove Wa is roughly ground. When rough grind is all over, the wheel spindle stock 27 is advanced forward for infeed with a little infeed quantity as compared with the rough grind time, and the table 13 is advanced left in the axial direction of the ball screw W, thus the ball rolling groove Wa is finely ground. At final fine grind, a laser beam is irradiated to the ball rolling groove Wa from a laser torch 33, heating it. Whereby some cracks produced by the rough grind are reduced. Consequently, there is unnecessary to apply the fine grind for long.

Title: Paper feed device
Inventor: NAGAO HIROYUKI
IPC: B65H3/06
Filed: 1991-11-11
Abstract: PURPOSE:To prevent the occurrence of a paper feed error such as the feed of superposed sheets by keeping a play between a paper feed roller axis and a gear fitted thereto, causing the rotation of the sheet feed roller axis in an anti-sheet feed direction after the passage of the trailing end of a paper sheet fed through a pinch roller and then moving the pinch roller to a standby position. CONSTITUTION:When a paper feed roller axis 1 is caused to rotate in a paper feed direction, a pinch roller shaft 17 is caused to rotate in a sheet feed direction via gears 6 and 8, due to the rotation of a gear 4 fitted to the shaft 1. Also, a reversing roller shaft 12 is caused to rotate in an anti-paper feed direction via gears 15 and 16, due to the rotation of a gear 13. If two or more sheets as superposed are fed to a gap between a paper feed roller 5 and a reversing roller 10, frictional resistance between both rollers 5 and 10 is weakened to such a level as lower than frictional resistance between a reversing roller shaft 12 and a torque limiter 11. As a result, a trouble of feeding superposed sheets is eliminated via the rotation of the reversing roller 10. After a sheet passes the a pinch roller 7, the paper feed roller shaft 1 is caused to rotate in an anti-paper feed direction, and the pinch roller 7 is kept away at a standby position.
