摘要： A dual-gate transistor formed of two transistors connected in series between a first power terminal and a first node is used as a charging circuit for charging a gate node (first node) of a transistor intended to pull up an output terminal of a unit shift register. The dual-gate transistor is configured such that the connection node (second node) between the two transistors constituting the dual-gate transistor is pulled down to the L level by the capacitive coupling between the gate and second node in accordance with the change of the gate from the H level to the L level.

摘要： An image forming apparatus and a maintenance method thereof are provided to enable rotation and replacement of a peeling claw at a suitable timing before the peeling claw is deformed or damaged. Several peeling members are disposed in a width direction of a drum-shaped photoreceptor. Each peeling member is disposed with a peeling claw and a collision sensor detecting that the peeling claw collides with a sheet. A collision history value of each peeling claw is stored and managed based on a collision detection signal from the collision sensor; if the peeling claw reaching a preset rotation request value exists in the read collision history values of the peeling claws, a rotation request of the relevant peeling claw is reported; the collision history value of the rotated peeling claw is rewritten; and if the peeling claw reaching the rotation request value does not exist, a print process is performed.

摘要： An image forming apparatus is provided in which an electrostatic latent image formed on a surface of a photoreceptor is developed into a toner image with a developing device, and in which a printing paper transported on a transport belt is brought into contact with the surface of the photoreceptor and an electric field is applied to the printing paper from a rear surface of the transport belt by a transfer roller so as to transfer the toner image onto the printing paper, the transfer roller capable of applying different levels of electric field to the printing paper, so that a predetermined transfer electric field is applied to a region other than a leading edge of the printing paper being transported, and that a weak electric field weaker than the predetermined transfer electric field is applied to the leading edge of the printing paper being transported. In this way, even in the presence of a projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor, thereby preventing toner contamination caused by a striping claw in contact with the leading edge of the printing paper.
摘要翻译：提供一种图像形成装置，其中通过显影装置将形成在感光体表面上的静电潜像显影成调色剂图像，并且其中在输送带上传送的打印纸与其表面接触感光体和电场通过转印辊从输送带的后表面施加到印刷纸上，以将调色剂图像转印到打印纸上，该转印辊能够对印刷纸施加不同程度的电场，使得预定的转印电场被施加到正在输送的打印纸的前端以外的区域，并且比预定的转印电场弱的弱电场被施加到被传送的打印纸的前端。以这种方式，即使在打印纸被切割时产生的投影存在的情况下，打印纸也从感光体的表面自然地剥离，从而防止由打印爪与印刷的前端接触的调色剂污染纸。

摘要： A charging device includes a rotatable screw gear, a motor, a support, and a protruding member. The screw gear is positioned along length of a linear electrode. The motor rotates the screw gear in forward and reverse directions. The support holds the cleaning member mounted so as to be in contact with the electrode, and is mounted unrotatably but reciprocably between a first end and a second end of the electrode. The member extends perpendicular to the length of the electrode from the support, and has a projection for being elastically fitted into a thread groove of the screw gear along a radial direction of the screw gear. The member is configured in such a manner that a distance between a starting point of elastic deformation of the member and a contact point between the projection and a thread of the screw gear differs according to whether the support is moved forward or backward.

摘要： Transfer roller(s) is/are such that either end thereof is formed from fibrous electrically conductive component(s) and such that cylindrical portion(s) in central region(s) is/are, for example, formed from metal roller-like structure(s), either fibrous electrically conductive component outer end being arranged so as to extend somewhat beyond either transfer/transport belt side. Furthermore, outside diameter(s) approximated by tips of respective individual fiber(s) of fibrous electrically conductive component(s) is/are somewhat larger than diameter(s) of metal roller-like structure(s). This makes it possible for electric field(s) to be applied, and for charging to occur, along the full width(s) of transfer/transport belt(s).

摘要： In a color liquid crystal display device, two capacitors are connected in parallel between a pixel signal line and an electrode of a liquid cell, or one of the capacitors is connected therebetween, or none of the capacitors are connected therebetween, in order to selectively set a potential of the electrode of the liquid crystal cell in any of four steps. Therefore, gradation display in four steps can be achieved without a digital-to-analog conversion circuit, so that the cost of the device can be reduced.
