Title: Time deviation correcting device for reproduced signal
Inventor: SUGANO HIROYUKI
IPC: H04N5/781
Filed: 1990-04-27
Abstract: PURPOSE:To accurately reproduce an image independently of an eccentric state generated at the time of setting up a floppy disk on a disk driving device by measuring the envelope of recording/reproducing information due to the eccentric rotation of the floppy disk and applying a correction signal for suppressing the generation of an envelope to a rotation control system based upon the measured result. CONSTITUTION:A reproducing envelope extracting circuit 11 detects an envelope output from reproduced recording information. The envelope signal from the circuit 11 is inputted to an output comparator 13, which measures time between the peak values of the envelope signal. A signal from the comparator 13 is inputted to a sine wave oscillator 14, which controls the waveform of an oscillated sine wave and applies a corrected sine wave signal for suppressing the envelope to the rotation control system. Since the rotation control system executes rotation control corresponding to the sine wave correction signal, the envelope of the recording/reproducing information due to the eccentric state can be suppressed.

Title: Image forming device
Inventor: ENDO HIDEKI
IPC: G03G15/00
Filed: 1989-04-28
Abstract: PURPOSE:To prevent the life-shortening of a photosensitive material without consuming a developer by impressing a bias voltage on a developing means and preventing the developer from adhering to the surface of a photosensitive body when the photosensitive body is rotated and controlled by a control means when it is not in copying operation. CONSTITUTION:Apart from a main motor which rotates a photosensitive drum 4 at the time of copying operation, a clutch 18 and a motor for low speed 19 are controlled by the control unit 12, whereby the drum 4 is intermittently rotated and controlled. When the drum 4 is not in the copying operation, it is rotated and controlled by a control means, and it is evaded that the bristle of toner as an foreign object for the drum 4 is brought into contact with the same part of the surface of the drum 4. Therefore, the life-shortaining of the photosensitive body is prevented. Moreover, when the drum 4 is rotated and controlled and not in the copying operation, a bias voltage is impressed on a developing unit 5, and the toner is prevented from adhering to the surface of the drum 4. As a result, such failure is solved that the toner is adhered to the surface of the drum 4 and gradually consumed.

Title: Variable amplifier circuit
Inventor: SATO TETSUO
IPC: H03G3/10
Filed: 1985-05-24
Abstract: PURPOSE:To vary the amplification factor with simple circuit constitution by connecting plural amplifiers to a common load circuit and driving selectively all or a part of the plural amplifiers. CONSTITUTION:An input signal Vin is fed from a terminal No.1 and when a control signal Vc is at a low level, a current flowing to a resistor R25 is a base current of a transistor (TR) Q26, the voltage drop is less, TRs Q25, 26 are both turned on and amplifiers 11, 12 are operative. Further, the both are operated in phase, when the current flowing to the amplifiers 11, 12 is the same, the voltage drop of a resistor R22 obtained as an output signal Vout is doubled. On the other hand, when the signal Vc is at a high level, the current flowing to a resistor R25 is increased and its voltage drop is increased. Thus, the TR Q26 is turned off, the amplifier 11 is operative but the amplifier 12 is inoperative. Thus, the voltage drop across the resistor R22 obtained as the signal Vout is halved.

In the test of the circuit 21, each circuit 21 has all at once a circulating count of the same values 0-15. Then the fault detecting circuit 23 gives a comparison to the values of two counting circuits 21 to detect the agreement or disagreement. And in case of disagreement, the error signal corresponding to each circuit 23 is turned on.

Filed: 1993-05-13
Abstract: PURPOSE:To make a high-contrast display even in a fast-response STN liquid crystal by providing a function generating means which generates the driving function of row electrodes and a means which converts its output into a column driving voltage with an arithmetic operation. CONSTITUTION:A liquid crystal panel 28 which makes the display of N rows by M columns is connected to row electrode signal lines 25-27 and column electrode signal lines 19-21 to form a matrix network. A column electrode driving means 18 inputs analog display data 16, converted by a column signal generating means 17 by one line and outputs the data of one line thereafter at a time. A row function generating means 22 writes a function by rows of a one-division time in an electrode driving means 24 through row function data 23. The row electrode driving means 24 outputs a voltage according to the value after the writing. For example, the function of a voltage applied to N row electrodes uses a Walsh function only for 8 rows, a one-frame period is set to 2N (N: number of display rows), and the Walsh function of 8 rows is driven with the number of division.

IPC: H04N1/17
Filed: 1989-04-28
Abstract: PURPOSE:To reduce power consumption and to decrease heating of a motor by preparing an idle line memory by 2 lines in advance prior to reading, storing picture information read in the unit of 2 lines to the line memory, processing the information sequentially and starting the drive of a pulse motor with 2-phase excitation without fail as to the subscanning. CONSTITUTION:The recording control system consists of a control section 11, a line memory 12, a read section 13, and a pulse motor 14. The control section 11 prior to the reading prepares idle area by 2 lines in the line memory 12 and controls the motor drive, read and storage by 2 lines in the unit of processing. Thus, even when a motor drive pulse number per line is an odd number as shown in figure (in figure, 3 pulses per line), since an even number of pulses is in use for the processing unit, the motor exciting state between processing units is always subject to one phase excitation.
