IPC: B60W10/10
Filed: 1987-12-29
Abstract: PURPOSE:To aim at stabilizing hydraulic pressure by using a desired speed shift ratio which is calculated from a desired rotational speed of an input side pulley as a speed shift ratio in order to control the hydraulic pressure for adjusting the tension of a belt in accordance with an engine torque and a speed shift ratio. CONSTITUTION:A control unit 91 controls the rotational speed of an input pulley which is detected and delivered by a sensor 94 to a desired input pulley rotational speed which is set in accordance with a rotational speed of an output pulley (vehicle speed) detected by a sensor 95 and a throttle opening degree (engine load) detected by sensor 93. Further, a desired speed shift ratio is obtained in accordance with a vehicle speed and an engine load so as to control a primary pulley, and the hydraulic pressure for adjusting tension of a belt for a secondary pulley is controlled in accordance with a desired pulley calculated from the desired input pulley rotational speed, and an engine load. Thereby it is possible to prevent the hydraulic pressure from hunting and to preform stabilized belt tension control.

Title: Optical character reader
Inventor: KATSUMI MASAO
IPC: G06K9/20
Filed: 1990-11-30
Abstract: PURPOSE:To accurately detect the multiple conveyance of slips and to prevent omission of a slip data by controlling the detection range in the slip conveyance direction by a detection range control means. CONSTITUTION:A transmitted light quantity measuring part 2 outputs the outputs voltage of a photoelectric conversion part 1 after converting it into a digital value (multilevel) and outputs a slip detection signal identifying the passage of a slip according to the digital value. When an area which greatly blocks light transmission exists on the slip such as a painted out print, a stamp and a seal, a detection range control section 3 receives, in advance, the information about the location of the printed band on the slip from the external controller and prepares and outputs a mask signal for controlling the detection range on the slip in the multiple conveyance direction of the slip based on the information. Thus, even when a printed matter which may influence the transmitted light quantity exists on the slip, the multiple conveyance of slips is accurately detected without the influence and the omission of a slip data is prevented.

Abstract: PURPOSE:To stably supply an output voltage by detecting fluctuating condition of the power supply voltage and then compensating for the target preset voltage for determining a turn-off timing of a semiconductor switch based on this fluctuating condition. CONSTITUTION:An output branched from an AC power supply 1 is input to a compensating means 9 and is then rectified into a DC voltage.

A DC voltage obtained by rectifying the AC power supply 1 and the target preset voltage are superposed. When the power supply voltage has changed, the target preset voltage is compensated. The compensated target preset voltage as explained above is input to a gate pulse control circuit 8 passing through a potentiometer setting voltage circuit 7 and is compared with a high voltage output input from an output voltage detecting circuit 5 to determine the optimum timing of the gate pulse. Thereby, a semiconductor switch 3 is turned off to generate a stable high AC voltage from the secondary side of a high voltage transformer 4.

IPC: G11B11/105
Filed: 1989-12-26
Abstract: PURPOSE:To eliminate the unfavorable influence due to leakage fluxes by magnetizing permanent magnets in directions opposite to directions symmetrical with respect to the optical axis of an objective lens. CONSTITUTION:Permanent magnets 3 and 4 are magnetized in directions opposite to directions symmetrical with respect to an optical axis (a). Therefore, directions of respective leakage fluxes are symmetrical with respect to the optical axis (a) but are opposite to each other, and consequently, perpendicular components of leakage fluxes have equal magnitudes and opposite directions on the optical axis (a) and are cancelled by each other. Thus, perpendicular components of leakage fluxes are about 0 in the vicinity of the light spot condensed on a recording medium 8 made of a perpendicularly magnetized thin film having a magneto-optical characteristic, and the influence of leakage fluxes upon recording, erasing, and reproducing of information is eliminated.
