Title: Delay circuit
Inventor: HANDA JINKOU
IPC: H03K5/13
Filed: 1983-03-10
Abstract: PURPOSE:To prevent the variation of the delay time by having conduction of a transistor connected to the output terminal of a charging/discharging circuit during the rise of an input pulse signal. CONSTITUTION:A capacitor 5b of a charging/discharging circuit 5 is charged from the breaking time of an input pulse signal (a) of a repeating frequency. When the terminal voltage reaches the threshold level VS of an inverter 4, the output of the inverter 4 is set at L to obtain a delay time DELTAt between input and output pulse signals. When the signal (a) is changed from L to H, a transistor 6 conducts. hen the electric charge of the capacitor 5b is instantaneously discharged. As a result, the output of the inverter 4 is set at H. Hereafter this operation is repeated by the signal (a), and therefore an output pulse signal with which the rise of the signal (a) is delayed by DELTAt is obtained. Thus it is possible to obtain a delay circuit with which the delay time of the fall of the input and output pulse signals is constant even though the repeating frequency of the signal (a) is approximate to the time constant CR of the circuit 5.

Title: Controlling method of bias voltage of developing device
Inventor: OKAMOTO YUKIO
IPC: G03G15/06
Filed: 1982-03-16
Abstract: PURPOSE:To obtain a stable, sharp picture without fogging, by controlling a bias voltage applied between a photoreceptor and the developer carrier of a developing device on the basis of a current flowing between the developer carrier and photoreceptor. CONSTITUTION:When an electrostatic latent image at a precedent projection part 6 passes by the position of the developing device 1, a bias voltage controlling circuit 7 allows a current-voltage converting circuit 7a to convert a developing current iD flowing through the developer carrier 2 into a voltage, which is compared by a comparing circuit 7b with a reference voltage from a reference voltage generating circuit 7c to perform control by the output of a control circuit 7d so that the developing current iD is ceased. A holding circuit 7e sends out the output of the control circuit 7d as it is to the developer carrier 2 by the timing signal of the CPU of the copying machine body while the electrostatic latent image at the precedent projection part 6 passes through the developing device 1, holds the output of the control circuit 7d right before the electrostatic latent image passes through the developing device 1, and sends out the developer carrier 2 until the electrostatic latent image on an original 5 passes the device.

Title: Switching control system
Inventor: TAKAHASHI TSUTOMU
IPC: H03K17/08
Filed: 1992-01-29
Abstract: PURPOSE:To stabilize an output current by turning on or off a switching element (SW) after synchronizing a control signal obtained by comparing the current value command signal of the SW with a current feedback signal after the SW to a clock pulse. CONSTITUTION:A switching element (SW) 1 is maintained in a turnedon state until a set value designated by a current command signal is reached. The rise of the SW 1 becomes dull due to a choke coil 2 and load. When the set value is reached, the SW 1 is turned off synchronously to a clock pulse Vt by means of a synchronization control signal Vo generated based on a current feedback signal from a current detector 4. As a result, a transfer diode 3 is energized and an electric current ID generated by the electromagnetic energy stored in the coil 2 flows out as an output current Io while the current Io is attenuated by the load. When the current Io is attenuated to the set value, the SW 1 is again turned on and similarly supplied the output current Io. By repeating such operations, the output current Io which finely pulsates to both sides of the set value is supplied.

Filed: 1988-02-23
Abstract: PURPOSE:To enable the highly precise detection of an azimuth, by conducting computation on the basis of geomagnetism detection outputs of two coils intersecting each other perpendicularly and by measuring the azimuth from each coil output. CONSTITUTION:An oscillator 1 supplies a rectangular wave to a primary coil PC of a flux gate sensor FGS, and an output signal of a coil NS.C is passed through a preamplifier 3 etc., detected by a synchronous detector 5 and supplied to a processing circuit 8 through an A/D converter 6. An output signal of a coil EW.C is processed in the same way and supplied also to the circuit 8. When the two coils NS.C and EW.C intersecting each other perpendicularly are once rotated herein at equal speeds in the horizontal direction, each coil detects geomagnetism, and the output signal thereof is multiplied by a constant to be transformed into such a signal as varying within the limits of a reference value. When this signal is divided by the reference value, the result of the division is inverse trigonometic functions, and thus an azimuth can be calculated from each coil output.

IPC: H01L21/265
Filed: 1980-03-31
Abstract: PURPOSE:To obtain a device which has stable surfacial properties by overlapping semiconductor layers after laminating an insulation layer containing P oxide and the other insulation layer on an insulative substrate. CONSTITUTION:If SiO2 12 is formed on a silicon substrate 11 containing a large quantity of phosphor, PSG layer 13 is generated. Next, P type polysilicon 14 is built up on a layer 12 not containing phoshor or phosphorous oxide and the prearranged part of it is monocrystallized by means of laser annealing. Following this process, SiO2 17 and polysilicon 18 are selectively formed on the monocrystal silicon. Using these as a mask, N diffusion is carried out in such manner that SiO2 12 at the lower surface may be reached. Under this constitution, PSG 13 is formed inside the substrate separate from the silicon layer 14, getting sodium in the SiO2 12 to provide stability. For this reason, the electrical characteristic of a surface between the silicon layer 14 and the SiO2 12 does not deteriorate in various manufacturing processes and the P-N bond bottom is covered by PSG 13 through the intermediary of SiO2 12, thus generating less leak current.
