Title: Driving device for supercharger
Inventor: TERAOKA MASAO
IPC: F02B39/04
Filed: 1991-02-20
Abstract: PURPOSE:To drive a supercharger at high speed and improve engine output by controlling a pulley diameter so that the speed of a driven side pulley is increased with a cam mechanism as an adjusting mechanism at increase of load torque applied on a driving device. CONSTITUTION:A cam mechanism 37 is constituted out of a cam groove 39 provided on a driven shaft 25 and a cam pin 43 studded on the boss part 41 of a movable pulley 29, and the cam groove 39 is formed so as to be inclined against the axis of the driven shaft 25. Hereby, at applying the large torque shown with the arrow line T on the movable pulley 29, the cam pin 43 is sufficiently pushed left to move the movable pulley 29 apart from a fixed pulley 27. Meanwhile, when the torque applied on the movable pulley 29 is small, the pushing force due to the cam groove 39 is small, and hence the cam pin 43 is sufficiently parted from the left end of the cam groove 39. Consequently, when a throttle is fully opened and load applied on a supercharger is large, the supercharger is controlled to be at high speed with the cam mechanism and engine output is improved.

Title: Driving method for semiconductor laser
Inventor: TOMITA SATORU
IPC: H01S5/068
Filed: 1984-02-15
Abstract: PURPOSE:To prevent discontinuity in the change in laser wavelengths caused by changes in temperature due to heat generated by driving currents by a method wherein a DC current component smaller in value than the laser emission threshold is bias-wise added to the driving current. CONSTITUTION:A semiconductor laser is driven by driving currents whose levels are switched between IB and I1. With the difference being very small between the currents IB and I1, changes in temperatures the semiconductor laser device is exposed to when switching is made between the two levels, that is, the level whereat the DC current component IB is bias-wise applied to the semiconductor laser as a driving current and the other level whereat a driving current I1 is applied. Accordingly, the current IB if set appropriately eliminates discontinuity in the change in laser emission wavelengths.

Abstract: PURPOSE:To secure a sufficient insulating property and a high bonding force by a method wherein a component lead is placed on a footprint which has attracted magnetic metal particles, it is covered with an adhesive sheet and the sheet is heated and pressurized. CONSTITUTION:Magnetized footprints 11 attract and gather magnetic metal particles 10 having plated layers of nickel, cobalt, iron or the like. After that, when component leads 21 are placed on the footprints 11 which have attracted the metal particles 10, the metal particles 10 are concentrated at the footprint parts 11 and a conductive property can be secured. In addition, when an adhesive sheet 15 is bonded, heated and pressurized, a large bonding force is obtained and the amount of the metal particles 10 between the footprints 11 is reduced. Thereby, an insulating property can be secured. When the magnetized footprints 11 are coated with an adhesive with which the metal particles 10 have been mixed, the metal particles 10 are concentrated at the fooptprints 11. In this case, the metal particles 10 are not scattered by a pressure and a vibration during a bonding treatment.
