Abstract: Method for the continuous vacuum cleaning of a substrate, characterized in that: a species is chosen that has a low sputtering efficiency and is chemically active with regard to the soiling matter; using at least one linear ion source, a plasma is generated from a gas mixture comprising predominantly the species having a low sputtering efficiency, especially one based on oxygen; and at least one surface portion of said substrate is subjected to said plasma so that said ionized species at least partly eliminates, by chemical reaction, the soiling matter possibly adsorbed or located on said surface portion.

Abstract: A pump control system has pump-displacement controls configured to selectively activate and deactivate a predetermined pump-displacement limit between physical displacement limits of a variable-displacement pump. The pump-displacement controls may be configured to adjust an operating displacement of the variable-displacement pump within a range bounded by the predetermined pump-displacement limit when the predetermined pump-displacement limit has been activated. Further, the pump-displacement controls may be configured to adjust the operating displacement of the variable-displacement pump without restriction from the predetermined pump-displacement limit when the predetermined pump-displacement limit has been deactivated.

Abstract: A fuel supply system includes a source of oxidizer providing oxidizer at an oxidizer pressure, a source of fuel providing fuel at a fuel pressure, and a fuel pressure regulator referenced to the oxidizer pressure. The fuel pressure regulator receives the fuel from the source of fuel at the fuel pressure, and discharges the fuel at an outlet pressure that is lower than the fuel pressure and proportional to the oxidizer pressure.

Abstract: A document scanning system includes a preview sensor that is dedicated to document previewing and distinct from any other sensor that is involved in the document scanning process. The preview sensor is preferably a two-dimensional sensor array that captures the outline of an entire document in parallel. The captured document outline is previewed on a display device relative to an actual image area that is defined by the scanning system. In an enhanced embodiment of the scanning system, the preview sensor captures an image that is printed on the document in addition to the outline of the document, so that the image of the document is also previewed relative to the image area. Providing a dedicated preview sensor that captures document position and image data in parallel enables real-time display of a document relative to the image area.

The preview sensor is preferably a two-dimensional sensor array that captures the outline of an entire document in parallel. The captured document outline is previewed on a display device relative to an actual print area that is defined by the copy system. In an enhanced embodiment of the copy system, the preview sensor captures an image that is printed on the document in addition to the outline of the document, so that the image of the document is also previewed relative to the print area. Providing a dedicated preview sensor that captures document position and image data in parallel enables real-time display of a document relative to the print area.

Abstract: This invention relates to a process and a device for the deposition of thin layers on a substrate using a plasma-CVD technique. The substrate itself, which previously has been made conductive by the deposition of conductive layers, is used as an electrode to create the discharge. In particular, the technique can be applied to the deposition of organosilicon layers on glass plates of large dimensions. The invention also relates to a glass substrate covered by thin layers including at least one metal layer, in particular silver, on which the organosilicon layer is deposited according to the process.

Abstract: A logic circuit family derived from the conventional 2 level single-ended cascode logic circuit. The basic logic circuit performing a 2--2 OA/AI logic function shown in the attached drawing is given for illustration purposes. It comprises: a logic tree 35 comprised of top and bottom stages 37, 36 dotted at the tree output 38 to perform a determined logic function; the top stage 37 includes a current switch comprised of two input transistors TX34, TX35 connected in a differential amplifier configuration with a reference transistor TX36. The bases of input transistors TX34, TX35 are provided with at least two level shifter devices. Preferably, input level shifter devices are Schottky diodes P31, . . . which move the voltages towards the more positive voltage VPP, to add an AND function on each of these input transistors.

Abstract: A latch that can serve as a bit storage cell in a random-access store. The latch includes an AND gate (diodes D1 and D2) the input IN of which receives the bit to be stored and the other input of which is connected to a write control line WRL. When no write operation is being performed, transistor T1 is turned off and the state of transistor T2 is dependent on output potential OUT. To perform a write operation, line WRL is activated (goes high) and the state of transistor T3 will depend on the value of the bit applied to input IN. Read operations are performed by means of another AND gate (diodes D4 and D5) and an emitter follower (transistor T4) connected via a bit line BL to an output circuit 2. By adding input transistors and emitter followers to the latch, a multi-port storage can be realized, several rows of which can be simultaneously written into and/or read out.
