Title: Optical pickup device
Inventor: MATSUI TSUTOMU
IPC: G11B7/09
Filed: 1981-11-20
Abstract: PURPOSE:To realize the miniaturization of an optical pickup device, by setting a deflecting lense which deflects the axes of the light beams sent from an objective lens and a galvanomirror at the upper part of the galvanomirror, and providing the tracking function to the deflecting lens. CONSTITUTION:A linear motor driving permanent magnet bar 14 is set within a linear motor electromagnetic driving part 15 so as to float above an optical pickup base 16. The polarities of the bar 14 and a permanent magnet bar 15A are set as shown in the figure. Thus the bar 14 is held by the attracting forces contrary to each other which are produced between the bar 14 and a polarized plate 15B. When a current flows to a coil 15C, the bar 14 moves toward an axis X by the Fleming's left-hand rule and since the direction of the current is orthogonal to the direction of the magnetic field of the bar 14. The direction and  the extent of this shift are controlled by the direction and the level of the current. The tracking toward the axis X is controlled by the electromagnetic drive  of a linear motor for a galvanomirror 11 and a deflecting lens 17.

Title: Method and device for production of magnetic recording medium
Inventor: NAGAO MAKOTO
IPC: H01F41/20
Filed: 1980-12-29
Abstract: PURPOSE:To increase both the vapor deposition efficiency and the magnetic properties, by promoting the ionization with the collision of the heat electron against the vapor current existing near a magnetic matter evaporating source and at the same time controlling the direction of the evaporating distribution of the ionizing vapor distribution to a supporter. CONSTITUTION:A magnetic matter 4 is vaporized at a hearth 3 in a vacuum container 1 with a heating means 5. Then the heat electron which is radiated by the heating of a heat electron radiation source 11 and properly controlled for the process of motion by an ionizing electrode 12 is concentrically hit to a position near an evaporating source and having comparatively high vapor current concentration. Thus the vapor current is ionized with high efficiency and then made to pass through an opening part of an auxiliary converging coil B. Thus the distribution of evaporation is extremely converged, and at the same time the center of the ionizing vapor current is properly displaced. Furthermore the distribution of evaporation is finally converged by a converging electrode 14, and at the same time a desired incident angle is obtained. As a result, the vapor deposition is carried out on the surface of a supporter 10 with high efficiency.

Title: Fuel supplying apparatus for engine
Inventor: EBINO HIROSHI
IPC: F02D41/04
Filed: 1988-07-25
Abstract: PURPOSE:To make it possible to restrain generation of unburnt components after fuel supply is stopped by supplying all or greater part of the quantity of fuels from a fuel supply means located nearest to a combustion room in a predetermined period before it is shifted to a fuel supply stopped state. CONSTITUTION:An engine control unit 40 stops fuel supply from fuel injection valves 23, 26 to a fuel cut cylinder 6 during the shift of an automatic transmission 31, for softning a shock relative to the shift. Prior to the fuel-cutting, a predetermined time before the shift is changed such that in the P, S ratio to the fuel cutting cylinder 6, the proportion of the injection from a P side fuel injection valve 23 is heightened. Thus fuel injection from a S side fuel injection valve 26 at which a predetermined time before the fuel-cutting is delayed is stopped or quantitatively reduced so that residual fuels in a passage portion 12 (c) separately formed for each of cylinders is restrained from being transmitted to an actuation chamber 7 during the fuel-cutting. Therefore, unburnt gases which are exhausted to an exhaust gas passage 29 during the fuel-cutting are largely reduced.

Title: Controlling method of electric railcar
Inventor: YAMAMOTO SHIROJI
IPC: B60L9/22
Filed: 1983-10-05
Abstract: PURPOSE:To enable to rapidly start an electric railcar from the state of stopping time and zigzag time irrespective of the route state by setting the slip frequency from the start to an ordinary reference slip frequency. CONSTITUTION:When an inverter start command signal 10 is inputted, a switch 4 is shifted from ''0'' side to ''1'' side. Thus, the value FXP produced by adding a reference slip frequency to the rotating frequency of an induction motor is outputted as an inverter frequency 18. When the inverter is started, the output V of the inverter is raised from 0 voltage to the value corresponding to the inverter frequency FXP at that time. If the induction motor current value IM becomes equal to the current limit value IP of the target current value of the induction motor, the output of a comparator 3 becomes ''1'', a constant current control 20 is started, and further shifted to V/F constant pattern operation.

IPC: B24B19/00
Filed: 1983-10-05
Abstract: PURPOSE:To have an enhanced transmission efficiency by allowing the end face of optical fiber to slide on the grinding face of a flat held in stationary state by reciprocative combination movement both in X- and Y-axes under pressure contact, and thereby providing possibility of grinding the optical fiber uniformly and in high precision. CONSTITUTION:An optical fiber plug P is depressed by a spring 5d to protrude a pherule tip below a seat board 4b, so as to place the foremost face of the fiber F in pressure contact with the grinding face 1a. Then a traveling table 6 is reciprocated along the X-axis by rotating a screw shaft 15 in regular and reverse directions, which is switched over by one-way gears 16, 17 at a specified period of cycle. When, on the other hand, a holder mechanism is reciprocated along Y-axis by the motor, the gear 16 makes regular and reverse rotation on a rack 18, wherein the shaft 15 is rotated regularly during said regular rotation to move the traveling table 6 in one direction along X-axis, and the compressed spring switches gears from 16 to 17, which in the same manner moves the traveling table 6 in the other direction along X-axis. Repetition of these motions provides an X-Y combined reciprocative motion, which enables uniform grinding of optical fibers.
