摘要： A copy reproduction machine is subdivided into discrete operating modules and coupled together by a shared communication line over which operating messages from and to the modules are transmitted. Each module includes a receiver for intercepting and capturing messages bearing the module's address and a transmitter for transmitting messages from the module and addressed to other modules over the shared communication line.

摘要： A programmable controller is used to control the operation of a xerographic reproducing machine adapted to run in a simplex or duplex mode whereby copies are made on either or both sides of web material fed in a single pass and then cut into individual copy sheets. A master program for operating the machine components to produce copies in accordance with the copy run instructions inputted by the machine user is provided. The master program includes a subroutine to place the user's copy run instructions in preselected order irrespective of the order in which the copy run instructions are received, such order being correlated with the order in which the originals are presented for copying. In a second subroutine the controller periodically performs housekeeping chores checking the operational status of the machine.

摘要： Synchronizing apparatus is disclosed in accordance with the teachings of the present invention wherein the operation of a first device is regulated in accordance with the operation of a second device. The phase relationship between signals representing the operation of the first and second devices, respectively, is determined by comparison means which produces a pulse width modulated signal indicative of said phase relationship. Control signal generating means responds to the pulse width modulated signal to generate an analog signal having an amplitude established by said phase relationship. Feedback means, including variable frequency generating means, is controlled by the analog signal to modify the operation of the first device whereby said first device is urged into a synchronous relationship with said second device and the signals representative of the operation of said first and second devices admit of a desired phase relationship.

摘要： A disk drive system includes a disk controller system having separate head positioning and data transfer subsystems and supporting up to four disk drives, two of which may be removable, portable drive units and two of which may connect through a standard ST506 interface. The removable disk drives incorporate a read and write protected data cylinder for storing information such as the maintenance history of the drive, and a read only cylinder for storing a unique serial number as well as other write protected data. The system also features a high capacity, high speed sector buffer which allows continuous transfers of data to or from noninterleaved sectors and supports concurrent disk and system accesses.

摘要： A control system for controlling the processing steps of an electrostatic printing machine including means for generating a series train of clock pulses, means for generating a series train of start or reset pulses and control logic responsive to the reset and clock pulses to generate a plurality of timed control signals for implementing certain of the processing steps. A transfer roller, the linear surface speed of which is synchronized with the moving speed of the photoreceptor, may be used to generate the reset pulses for the successive cycle of processing operation. The intervals between the successive reset pulses, called pitches, are in effect marked by the clock pulses, some of which are used to generate the timed control signals.

摘要： A toner powder reclaiming apparatus for use with the developing system of an electrostatic reproduction machine including a rotating drum in the path of movement of an airflow containing electrically charged toner particles which become attracted to the drum. A scraper blade is in contact with the drum for cleaning the toner of the collecting surface thereon. The toner particles thereby removed are directed automatically into the toner supply contained for the developing system.

摘要： The present invention is concerned with a character input device, a disc memory, an output marker, and a character generator for converting byte format character information into an output marker bit stream format, and for allocating the converted bit streams onto the disc memory. The stored bit streams can then be retrieved to directly drive the output marker or to be re-allocated onto the disc memory (after merging with presently converted bit streams if appropriate). In another feature of the invention, the converted or generated bit streams are represented in a compressed form (described by a four bit run length code). These bit streams in the compressed form can be merged by the character generator directly into this compressed form without having to first decompress the bit streams, merge, and then compress again. Also printing systems can be configured using one or more character generators committed to one or more disc memories, and in turn, each disc memory can drive one or more printers.
