摘要： A method of maintaining a surface charge on a photoreceptor within a predetermined voltage range is provided, comprising the steps of providing a charging device adjacent to a surface of the photoreceptor, determining a reference voltage to be applied by the charging device to the photoreceptor surface to establish a first photoreceptor surface voltage, and applying the reference voltage to the surface of the moving photoreceptor with the charging device while measuring a first photoreceptor current. The method further comprises comparing the first photoreceptor current to predetermined characteristics of the photoreceptor to calculate a first output value, comparing the first output value to predetermined characteristics of the photoreceptor and calculating a first correction voltage, and applying the first correction voltage to the photoreceptor surface with the charging device to obtain a surface voltage on the photoreceptor that is within the predetermined operational voltage range.

摘要： A pipe connector structure, for coaxial pipe sections having a common liner, and including a pair of flange members, constructed to be drawn together by suitable bolt or other attachment means, which flange members include flange bodies having remote flange ends that are inwardly and downwardly tapered and constructed to coact with pipe securement rings. Between such rings is a sleeve, split in two halves along a diameter thereof for positionment about the liner and constructed, if expanded radially outwardly by radial expansion of the liner, upon the application of internal pressure means, to come in contact with the inner surfaces of the machined flange members to delimit such radial expansion. Alternatively, where the liner is essentially non-radially expandable, then gaps in the split sleeve can be closed and such sleeve and flanges can act conjointly as to the liner to counteract radial liner burst pressures. Pipe ends to be coupled together are positioned against interior shoulders of the split sleeve. Frusto-conical split pipe-gripping rings directly about opposite ends of the sleeve and coact with the flange members to make up the coupling and grip the pipe sections.

摘要： A system for registration of one or more color separation images on a photoconductor belt prevents misregistration that otherwise can occur between different scan lines and between different latent images due to side-to-side movement of the photoconductor belt. The registration system operates to detect movement of the photoconductor belt. Based on the detected movement, the system operates to control modulation of laser beams used to form the latent images to ensure precise registration of the color separation images. As one advantage, the movement of the photoconductor belt can be detected precisely and inexpensively by a photodetector scanned with the same laser beam used for imaging.
