Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To obtain a noncontact developing device capable of stably obtaining an image having high resolution and developability, without a vertical streak, development unevenness, etc., on the image by locating the whole of a control electrode plate, so that it is in contact with a developer layer and on a developer carrier side of a tangent perpendicular to the center line of an image carrier and a developer carrier. SOLUTION: As the installation position of the whole of the control electrode plate 80, a position where the whole of the control electrode plate 80 is located in contact with the developer layer and on the side of a developing sleeve 130 of the tangent M perpendicualr to the center line (p) passing through the centers of a photoreceptor drum 10 and the developing sleeve 130 is obtained. When an electrode part 82 is installed to be on the side of the photoreceptor drum 10 beyond the tangent M, a toner cloud is easily infiltrated to the electrode part 82 and soiling onto an electrode with the toner easily occurs.  On the other hand, when the electrode part 82 is installed on the side of the developing sleeve 130, without going beyond the tangent M, the electrode part 82 is away from a developing region to the upstream side and the soiling on the electrode caused by the toner cloud never occurs.

Title: Read/write system of mass storage unit
Inventor: FUKUHARA JIYUNICHI
IPC: G06F15/16
Filed: 1979-02-16
Abstract: PURPOSE: To reduce greatly the time of read and write operations to and from a  mass storage unit shared among processors, by sending the magnetic head position  of the mass storage unit to each processor.  
     CONSTITUTION: Once an input-output start instruction is outputted from processor CPU1 to mass storage unit DA1, driving-arm driver DR moves magnetic head HD to a desired position and also sets a read/write position to target register TG. A value detected by position detection circuit SN is compared with that of register TG and interrupt circuit IT is instructed to send an interrupt signal. Input-output control part IOM of CPU1 is informed of the interruption of interrupt circuit IT  and a read/write instruction is resent. This read/write instruction puts the read and  write from CPU1 to mass storage unit DA1 into effect. Here, since the input-output  instruction minimizing the movement of the magnetic head of mass storage unit  DA1 is searched and sent out, the read-write time is shortened.

Abstract: PURPOSE:To specify a defective FF by setting respective FFs of a serial scan chain, enabling presetting, shifting a scan after the respective FFs are set in a prescribed value, and comparing an output bit row of the chain and a preset bit row with each other. CONSTITUTION:A negative pulse is impressed upon a reset terminal, and FF1-FF5 are cleared to (0). Next, a negative pulse is impressed upon a preset terminal, and the FF1-5 are set in (0, 1, 0, 1, 0). Next, a scan is shifted to a scan chain, and the bit pattern is detected, and it is compared with an initial bit row (0, 1, 0, 1, 0) by a comparing part l. An expected bit row is (0, 1, 0, 1, 0), and when it is different from this, it means that a defective FF exists in the chain. In this case, since an output bit row becomes immovable to the expected bit row with the FF as its boundary, an immovable place or the next stage can be specified as the defective FF.

Abstract: PURPOSE:To prevent an input signal from varying in DC level by controlling the DC level of the input signal and a slice level differentially, receiving a couple of the input signal and slice level differentially, and receiving a differential output by a differential amplifier. CONSTITUTION:The circuit consisting of transistors (TR) 21, 22, 31, and 32 controls the DC voltage of the input signal and the slice level corresponding to it differentially. Therefore, differential TRs 41 and 42 which receive collector outputs of the TRs 21 and 22 slice the input signal with a DC potential V1+DELTAV by a slice level V1-DELTAV, so that an input signal with the potential V1+DELTAV after signal components lower than the slice level V1-DELTAV are sliced appears at the common emitter of the TRs 41 and 42. Further, differential TRs 51 and 52 which receive collector outputs of TRs 31 and 32 slice the input signal with the DC potential V1-DELTAV by a slice level V1+DELTAV and a signal component higher than V1+DELTAV appears at the common emitter.

Abstract: PURPOSE:To perform uniform sub-scan feeding, by a method wherein the recording time for each line in a page is made to be a fixed period of time required for recording a line containing the maximum number of mark picture elements, and recording is conducted while feeding a recording paper in a sub-scanning direction at a fixed velocity. CONSTITUTION:When an image signal (a) is inputted into a terminal 1, the signal is sequentially written into a page memory 4, the number of mark picture elements in a line is counted, and an output from a mark picture element counter 5 is inputted into a maximum value detecting part 6. A ROM7 stores the period of time required for recording a line containing the maximum number of mark picture elements, and information stored at an address designated by an output from the part 6 is outputted to a timer 8. When a starting pulse (e) is inputted into the timer 8, a signal (f) is set ON, and it is turned OFF when the recording time indicated by an output from the ROM7 elapses. A controlling part 14 supplies a step pulse to a stepping motor 12 when the recording in the line is completed and the signal (f) is turned OFF. In the period of recording a page, the period of the signal (f) is constant, the recording paper is fed in the sub-scanning direction at a fixed velocity, and the recording time for each line is constant, so that feeding is conducted uniformly.
