摘要： In an electrostatic recording apparatus, a recording medium is transported to a vaporized solvent supply unit where a vaporized organic solvent is given to the recording surface of the recording medium. Then, the recording medium is transported to an electrostatic recording head where an electrostatic latent image is formed on the recording medium. Next, the recording medium is transported to a development processing unit where the development process of the electrostatic latent image using a liquid toner is performed.

摘要： The invention relates to a method of controlling the pressure in a compression chamber (10), particularly in a pneumatic braking device for a recording medium (12) in the form of a strip, in which method the actual pressure (Ip) in the compression chamber is set in relation to the actual angle (Iw) of rotation of a turning valve (14). The actual angle (Iw) of rotation of the turning valve (14) and the actual pressure (Ip) in the compression chamber (10) are recorded. An ideal pressure (Sp) and an ideal angle (Sw) of rotation associated with this ideal pressure (Sp) are predetermined and pressure deviation (Dp) between the actual pressure (Ip) and the ideal pressure (Sp) and also a deviation (Dp) of the angle of rotation between the actual angle (Iw) of rotation and the ideal angle (Sw) are fixed. Setting means (40) adjusts the angle of rotation on the turning valve (14) firstly in relation to the deviation (Dw) of the angle of rotation and subsequently in relation to the pressure deviation (Dp). The invention also relates to a sensor (22, 22', 22') for measuring the angle of rotation.

摘要： A system and method for utilizing web (60) that is free of tractor pin feed holes comprises the driving of the web (60) along a predetermined path within the utilization device. A web guide (90) is provided in an upstream location from a utilization device element (64). The guide (90) engages width-wise edges of the web (60) and forms the web (60) into a trough to stiffen the web (60). A drive roller (72) and a follower roller (76) impinge upon opposing sides of the web (60) and rotate to drive the web (60) through the guide (90). The drive roller (72) is located adjacent to the guide (90) according to a preferred embodiment. A registration controller (150) is utilized to synchronize the movement of the web (60) with the operation of the utilization device element (64). The controller (150) includes a drive controller that controls the speed of either the drive roller (72) or the utilization device element (64) to maintain the web (60) and the utilization device element (64) in appropriate synchronization.

摘要： Described herein is a multi-station printing system having a plurality of photoreceptor units (24. 24', 26, 26'). Each photoreceptor unit (24, 24', 26, 26') has a torque limited drive unit (25, 25') which provides rotational torque to overcome most of, but not all, of the rotational drag forces on the photoreceptors (24, 24'). In this manner, contact of web (12) with the photoreceptor (24, 24') can control the speed of the photoreceptor (24, 24') by overrunning the torque provided by the motor (25, 25') but minimizing the possibly of slip or tearing of the web (12) due to high torque loads imparted thereto by the plurality of photoreceptor units (24, 24', 26, 26') of the printing system.

摘要： An image forming apparatus capable of cutting a strip-shaped continuous sheet on which an image is formed to a desirable cutting length. A rolled-sheet (4) is conveyed by registration rollers (LL) and the like. The rolled-sheet (4) is further led to the vicinity of a photosensitive drum (20) through pre-transfer rollers (TL). The rolled-sheet (4) to which a toner image has been transferred is subjected to toner fixing processing by a fixing device (35). When the leading end of the rolled-sheet (4) reaches the pre-transfer rollers (TL), the rotational speed of a sheet feeding motor (PFM) is increased during predetermined time. Consequently, the sheet conveying speed on the upstream side of the pre-transfer rollers (TL) in a direction of sheet conveyance is increased, thereby forming slack in a sheet portion between the registration rollers (LL) and the pre-transfer rollers (TL). Consequently, tension exerted on a sheet portion between the fixing device (35) and the pre-transfer rollers (TL) does not affect the conveyance of the sheet by the registration rollers (LL). If operation timing of a cutting mechanism (80) is determined on the basis of the number of output pulses of a pulse output unit (PW) for detecting rotation of the sheet feeding motor (PFM), therefore, the rolled-sheet (4) can be reliably cut to a desirable length.
