Title: Digital signal reproducing device for cassette tape
Inventor: YOSHIDA MASAO
IPC: G11B5/09
Filed: 1983-05-30
Abstract: PURPOSE:To reproduce a digital signal from a cassette tape by clamping an audio signal from a cassette recorder, making its output pass through a BPF constituted of an operational amplifier, and waveform-shaping it by a zero crossing comparator. CONSTITUTION:A reproducing signal from an earphone terminal of a cassette recorder becomes an input signal. Said signal is clamped to about + or - 0.7V by diodes D1, D2, and an unnecessary high frequency signal is eliminated by an LPF constituted of R1 and C1. A band pass filter is constituted of an operational amplifier, its band frequency is set to fL and fH, and when R3/R2 is set to a suitable value being larger than ''1'', an AC waveform which is swung up and down is obtained centerning around voltage VS divided by a resistance R4 and R5 between voltage VC and an earth. A zero crossing comparator CMP waveform-shapes an AC wavform which has passed through a BPF, to a pulsative square wave. In this way, a reproducing performance can be improve remarkably by shaping a waveform to a square wave.

Title: Power generation controller of series hybrid electric vehicle
Inventor: YAMAMOTO TATSUYUKI
IPC: B60L50/10
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To prevent an engine for generator from running at high speed while the vehicle is stopped. SOLUTION: This SHEV(series hybrid electric vehicle) is put to a test running on a given running route using the battery power only. During the test running, a power consumption pattern of the battery is stored in a running pattern registration section 21. The mean consumption power during the test running is calculated by a mean consumption power calculating section 22. A power generation pattern registration section 24 calculates a little higher target generation power than the mean consumption power calculated by the mean consumption power calculating section 22 and then stores the value as a target generation power. After that, a supplementary charging region judging section 25 monitors an actual power consumption pattern of the vehicle during normal running.  When the actual power consumption pattern of the vehicle agrees with the power consumption pattern stored in the running pattern registration section 21, the judging section 25 determines that the vehicle is running on the running route for the test running and an engine speed command section 26 constrols an engine for generator so that the target generation power stored in the generation pattern registration section 24 can be obtained.

Abstract: PURPOSE:To improve the yield of sheet production by making calculations based on the width distribution in the longitudinal direction and sheet thickness of a rolling material subjected to passes before the final cross rolling pass to determine the target sheet thickness of the final pass of cross rolling and executing rolling of the final pass. CONSTITUTION:The distances w1, w2 from the central axis (x) in the visual field of a width length gage 2 on the inlet side up to the ends on both sides of the rolling material 1 are measured at a specified pitch over the entire length in the final pass stage of the cross rolling of a rolling mill. The values are led to a computer 6, by which the true width Wxi in the measuring position Xi of the width length gage 2 is calculated and is stored in the computer 6. The sheet width Wx in the optional position in the longitudinal direction within the rolling material 1 is then determined with high accuracy. The target sheet thickness Hw of the final pass of cross rolling is calculated and the target roll gap G' of the final pass is determined so as to maximize the rolled product length having the required sheet thickness and width after the end of finish rolling based on the width distribution in the longitudinal direction and the average thickness of the rolling material 1 during measurement.

Abstract: PROBLEM TO BE SOLVED: To highly precisely stabilize output voltage Vo in a constitution where a pair of bipolar transistors constituting the initial stage circuit of an error amplifying circuit are used. SOLUTION: The divided voltage of a connection point, which is obtained by dividing output voltage Vo by a pair of voltage divider resistors R1 and R2, is given to the base of one bipolar transistor in the initial stage circuit of an error amplifier circuit and reference voltage is connected to the base of the other bipolar transistor through a correction resistor R0.

The resistance values of the voltage- dividing resistor R2 and the correction resistor R0 are selected to be equal and the base currents IB1 and IB2 of a pair of bipolar transistors are made to be equal. Thus, the voltage drop of the voltage-dividing resistor R2 and that of the correction resistor R0 are made to be equal.  Consequently, output voltage V0 can highly precisely be stabilized in spite of the fluctuation of the base currents IB1 and IB2.
