IPC: G06K9/24
Filed: 1980-01-14
Abstract: PURPOSE:To smooth out folds and creases automatically to obtain a good picture signal, by making the circumferential speed of the running roller of a smaller frictional coefficient larger than that of the running roller of a larger frictional coefficient and by moving rollers manually on the original to the subrunning direction. CONSTITUTION:Running rollers 5 and 6 positioned forward and backward respectively in the advance direction of machine body 1 are rotated in directions opposite to each other, and the circumferential speed of running roller 5 of a small circumferential frictional coefficient is larger than that of running roller 6 of a large frictional coefficient, and therefore, original O between running rollers 5 and 6 is pulled toward running roller 5 due to idle-running of running roller 5 on the original which is stopped by the contact part between original O and running roller 6, and consequently, folds and creases of original O are smoothed out.

Title: Saturation type logical circuit
Inventor: KIYOZUKA NOBORU
IPC: H03K19/088
Filed: 1982-01-12
Abstract: PURPOSE:To accelerate the ON/OFF operation of an output transistor, by controlling an active pull-down circuit with the collector potential of a level shift transistor of a saturated type logical circuit. CONSTITUTION:The emitter of a transistor TRQ2 which gives a level shift to the output of a TRQ1 of an input circuit is connected to the base of a phase split stage TRW3. The emitter of the TRQ3 is connected to the base of an output TRQ4, and the emitter of the TRQ4 is grounded. Thus a saturation type logical circuit is formed. The collector potential of the TRQ2 is divided by resistances R3 and R4 and then connected to the base of a TRQ7 via a resistance R8 to form an active pull-down circuit. When a high level of potential is fed to the input, the TRQ1 is turned off with TRQ2-Q4 turned on successively and TRQ5 and Q6 turned off, respectively. Thus the output is set at a low level. In this case, the resistances R2-R4 are selected so as to turn off the TR7. When the input is changed to a low level from a high level. The TRQ1 is turned on with the TRQ2-Q4 turned off successively and the TRQ5 and Q6 turned off, respectively. Thus the output is set at a high level. In this case, the currents flowing through the R2 all flow to the R3 and R4, and the TRQ7 is turned on with the TRQ4 turned off quickly.

Title: Detection method for alternating current existence of electric wire and power cable
Inventor: ORITO KATSUYOSHI
IPC: G01R15/18
Filed: 1979-01-12
Abstract: PURPOSE: To realize detection for presence or absence of the alternating current with no effect received although the induction magnetic field exists by installing two units of circular coils near the electric wire or the cable and thus detecting the presence or absence of the phase difference for each electromotive force.  
     CONSTITUTION: Two units of circular coils 2 and 3 are put at the position featuring optional angle θ to the center of 3-unit twist electric wire 1 and also equidistantly from the center of wire 1 and near wire 1 to which the three-phase alternating current flows. Then coils 2 and 3 are connected to the phase difference measuring unit not shown in the diagram. In case the induction magnetic field exists, no phase difference is detected by the phase difference measuring unit when no alternating current flows to wire 1. While the phase difference of the composite magnetic field is detected between the magnetic field caused by the alternating current and the induction magnetic field in case the alternating current is flowing. Thus the presence or absence can be detected for the alternating current regardless of the existence of the induction magnetic field.

Filed: 1993-01-12
Abstract: PURPOSE:To automatically save electric power by holding the handy operation section of a vacuum cleaner having a floor suction tool, and controlling the rotation of a suction rotary brush in response to the state that the light of a light emitting element is detected by a light receiving element. CONSTITUTION:A grip sensor constituted of a light emitting element 2 and a light receiving element 3 is provided at a grip portion inside the handle section 1 of a handy operation section 103 fitted between a vacuum cleaner main body and an extension pipe. The handle section is gripped to advance or retreat the vacuum cleaner main body and the extension pipe.

When the grip is insufficient, the revolving speed is reduced. When the fingers are removed from the handle section 1, the rotation is stopped. The rotation of the rotary brush is controlled, and the power consumption is saved.

Title: Video reproducing device
Inventor: MITANI HIROSHI
IPC: G11B20/06
Filed: 1987-01-09
Abstract: PURPOSE:To obtain a synchronizing signal having few false signal and to attain a stable time base correction by separating an FM demodulator for a video signal and an FM demodulator for the synchronizing signal. CONSTITUTION:A band control is not carried out to an FM modulating signal inputted in order to obtain a complete demodulating signal band by the FM demodulator 103. In the FM demodulator 105, the band is controlled to an inputted FM modulating signal in a filter 104. Before an FM modulation is carried out, the band control is executed in such a manner, a part in which an instantaneous frequency is deteriorated which is generated by the defect of a disk cannot pass the filter but compensated by the noise to the carrier frequency of the pass band of the filter. Accordingly, when the output signal of the demodulator 105 is synchronously separated in a synchronizing separator circuit 106, the synchronizing signal having few false signal can be obtained. When this synchronizing signal is compared with a reference signal in a phase comparator 107, an erroneous time base error is not generated by the false signal but the stable time base correction can be executed.
