摘要:
Printing apparatus including a printing head (1), which apparatus comprises a buffer memory (7), designed to be filled, at a defined speed, by data representing lines to be printed on a printing medium (11) and to be emptied line by line for each printing of a line by the head, and computation member (6) designed to determine, prior to the printing of each line, the volume of buffer memory (7) remaining available (L-xi), to determine therefrom a printing speed (Xj) of the line in question and accordingly to control member (3) for adjusting the printing speed (Xj) of the head (1).
摘要:
An electro-photographic printing device has a development location where toner is transferred onto a drum in proportion to the amount of light charges on the drum and a transfer location where toner is transferred from the drum to a sheet of paper. A heater unit for fixing the toner by heating it to a predetermined temperature has a heater and a blower for heat removal. Responsive to a call for printing, data to be printed are stored in a memory. The heater is energized until a set temperature is obtained. Printing is initiated as soon as the set temperature is obtained. The blower is stopped after heating has been discontinued, after printing has been completed, until there is a new call.

The machine includes a frame (11) and a film (12) for one of two substrates (1, 2) to be pressed onto the other under a plate (4). It is then possible to polymerize by points a glue joint (3) so as to assemble the two substrates. Accurate displacement means (7, 8, 9, 10) and observation means (13, 14, 15) are also provided. Application for the embodiment of liquid crystal cells.

Magnetic characters arranged in a row on a check are read in an apparatus effecting relative linear displacement between the check and a magnetic reader. The displacement is effected either by manually removing the check from the apparatus, or by manually moving the reader.
摘要:
A microprocessor memory safeguard device comprising a switch having two it terminals and a common terminal. The common terminal is connected to a first terminal of the memory and to the logic zero of the microprocessor. The other input terminal of the switch is connected to one terminal of a battery. The second terminal of the memory is connected to the other terminal of the battery. The second input terminal of the switch is connected to an initialization line of the processor whose initialization input is also connected to the line. The initialization line is connected directly to a power supply source. The initialization line could also be a data bus interconnecting a plurality of microprocessors.

An apparatus for measuring a dimension of a workpiece, for instance a worece being machined on a lathe, comprises a unit which may be moved toward and away from the workpiece. That unit includes a forked carriage one of the prongs of the fork having a light source which directs a parallel light beam perpendicularly to the direction of movement of the carriage toward the other prong. Light sensitive means on the other prong deliver a first signal when the light beam is interrupted by the workpiece upon movement of the unit and a second signal when the light beam is re-established.
摘要:
The invention concerns a printing device or head for a printer or the likend to a process of making same. The device comprises a plurality of needles each having an electro-magnet and a metal plate associated therewith, a selected needle being displaceable against an information support upon energization of the associated electro-magnet. The electro-magnets are supported in a base. In accordance with the invention each electro-magnet includes a U-shaped magnetic circuit, the base including housings for magnetic circuits. A surrounding, insulating material is disposed between the arms of the magnetic circuit and around the windings of the electro-magnets.

The system comprises a processor, a routing unit (3), linked to the procer, in order to be linked to a line (10) of a telephone network (11) and to an associated telephone handset (12), a modem (4) linked to the processor and to the routing unit (3), an analysis and printing assembly and a control console, which are linked to the processor. It also includes a reversible radio module (2), linked to the routing unit (3) and to the processor in order to communicate by cordless link either, in handset mode, with a cordless telephone base linked to the telephone line, the associated handset being linked to the routing unit (3), or, in base mode, with the associated handset (12), the routing unit (3) then being linked to the telephone line (10).
摘要:
A card reader that is resistant to vandalism is disclosed. The card recei (1), includes a slot (4) for receiving the front part of a card (3), and card reader (1L) using it. The card receiver (1) includes a bending element (6, 17P) applying, to the card (3), a torsional moment with respect to a bearing lip (5) of the slot (4) or to an opposed second bearing element (10), so that the card (3), once broken, can be pushed in by another card so as to lose contact with the bearing lip (5) and to drop into a cavity (12).
