IPC: H02J3/38
Filed: 1992-02-18
Abstract: PURPOSE:To quicken an excessive response at the time of a sudden change of frequency by comparing the clock number of the inverter-driving frequency signal in one period of the frequency of integral times of the standard frequency of a three-phase AC power supply with that of the frequency of integral times of a frequency detected from the three-phase AC power supply, by detecting the difference between respective clock numbers and by feeding the difference forward to the inverter-driving frequency signal. CONSTITUTION:The clock number by the inverter-driving frequency signal fS; e.g. 614, 4KHz/300; in one period at the frequency, e.g. 300Hz, of integral times of the standard frequency of a three-phase AC power supply is 2048 and is previously set in up/down counters 8, 9. Then, the clock number is counted down in the counters 8, 9 by the clock number of the frequency signal fS in one period of the square-waved signal fCS of the frequency of integral times of the standard frequency detected and converted from the three-phase AC power supply. The difference between the counted- down number and the clock number 2048 and a polarity by the comparison of the two numbers are detected by logic circuits 11, 12 and the added or subtracted clock number based on a detected value is fed forward so that the frequency fS is addition- subtraction controlled.

Title: Information processor
Inventor: SHIMADA YASUHIRO
IPC: G11B9/14
Filed: 1993-03-01
Abstract: PURPOSE:To simply control the spacing between a probe and a recording medium by exerting magnetic force on a magnetic material composing a cantilever by means of a permanent magnet, bringing the probe into contact with the recording medium and performing information recording/reproducing. CONSTITUTION:An electrically conductive probe 101 whose tip is in contact with the surface of a recording medium 102 is arranged. In such a case, the magnitude of attraction by magnetic force is in inverse proportion to the square of a distance between a cantilever 103 and a magnet 122, since hysterisis exists from the state in which the tip of the probe 101 is in contact with the recording medium 102 to the state in which they are separated, the variation of the spacing between probes on the respective cantilevers without actuators and the recording medium is compensated so as to be a weak contact condition instead of a strong contact condition on which force is exerted between the probe 101 and the recording medium 102. By using this method, the spacing control between the probe and the recording medium is performed in the simple style of contact.

Title: Resin sealing metallic mold
Inventor: SHIMIZU CHIHIRO
IPC: B29C45/26
Filed: 1984-03-30
Abstract: PURPOSE:To prevent a gap between upper and lower metallic molds as well as a burr in a formed product from happening by a method wherein, in resin sealing metallic molds of a semiconductor product, a post provided in the guide of lower mold is depressed into the lower mold during molding operation. CONSTITUTION:A bush 34 is fixed to an upper mold base 31 while another bush is mounted in the hole 35 of lower mold 32 to make a post 37 free-slide up and down. The top end of spring 39 abuts against the bottom end of post 37 to lift the post upward. In the molding process, the upper and lower molds are aligned by means of inserting the tapered surface of post 37 into the tapered surface of bush 34 before the opposite surfaces B of upper and lower molds come into contact with each other. When both metallic molds are pressurized to make the opposite surfaces B come into contact with each other, the post 37 is depressed into the lower mold base 32 against the elastic energy of spring 39 for molding operation. Through these procedures, any gap between the upper and lower metallic molds may be prevented from happening since the overall molding forces are exerted on the opposite surfaces B with the guide of lower mold having no influence upon the molding operation.
