Patent EP-0455472-A1 (EP)
Inventor: JOVE STEPHEN ALAN
IPC: G11B5/39
Filed: 1991-05-01
Abstract: An amplifier circuit produces an electrical output signal whose magnitude is representative of a signal produced by a magnetoresistive (MR) element (Rmr) and also protects the MR element (Rmr) from electrical short circuits between the element (Rmr) and on adjacent conductive surface. A first feedback loop biases the MR element (Rmr) with a bias current and amplifies a signal current for causing the MR element (Rmr) to produce a circuit output signal corresponding to dRh/Rh and in which any dc offset error is minimized R h is the resistance of the MR element and dRh is the magnetic-signal-induced change in the resistance of the MR element. A second feedback loop insures that the MR element (Rmr) is held at a preselected reference potential and that no current will flow sufficiently to damage the element in the event of a short circuit between the element and the surface. The feedback loops are interconnected by outputs of the respective feedback loops being commonly connected to the bases of a pair of input bipolar transistors (Q1,Q2), whose respective emitters are connected to opposite terminals of the MR element (Rmr).

Abstract: A system and method for cleaning a water intake screen (3) of the type disposed between a manmade channel (5) which leads to a nuclear power plant, and a body of water (7) such as a lake or ocean. The system generally includes a pressure pulse generator (30) including an elongated manifold (32) for generating shock waves in the water surrounding the screen (3) in order to loosen and remove debris therefrom, and a debris removal assembly (36) including a net (40) circumscribed by a frame (94) which is placed in opposition to the apertures (34) of the manifold (32) on the other side of the screen (3) for capturing and removing the debris loosened. For a bandtype intake screen (3) on rollers (11, 13), the manifold (32) is placed within the loop of screen material with the apertures (34) directed toward the downstream section (27) of the screen (3) and into the net (40) of the debris removal assembly (36). The foraminous nature of the net (40) allows it to capture debris dislodged by the shock waves without in turn being damaged by the shock waves. When the net (40) becomes filled with debris, the drive assembly that rotates the rollers (11, 13) that turn the band-type screen (3) is stopped, and the frame (94) that supports the net (40) is craned above the water (7) in the channel (5), pivoted over a trough (109) to dump the debris, and is then repositioned in opposition to the manifold (32).

Abstract: An initializing circuit (20) for setting the initial state of a latching circuit (30) in a semiconductor device when switching on a power supply. The initializing circuit is provided with a sensing circuit (TR1, TR2, R, 21) which operates according to switching on the power supply and senses that the power supply voltage (Vcc) increases to a predetermined voltage, and a circuit (22) for controlling output levels which responds to a sense signal (V1) outputted from the sensing circuit and pulls up the level of the output signal (Vout) of the initializing circuit to a high potential level or pulls down it to a low potential level. After the power is interrupted and when the power is supplied again, the latching circuit (30) is fed with the output signal controlled by the circuit (22) as its power source voltage. Consequently the latching circuit can be reliably initialized, and the malfunction on restart is prevented.

Abstract: A plasma reactor (10) preferably uses a split electrode (26) which surrounds a plasma dome (17) region of the reactor, is driven by high frequency energy selected from VHF and UHF and produces an electric field inside the reactor, parallel to the wafer support electrode (32c). A static axial magnetic field may be used which is perpendicular to the electric field. The above apparatus generates a high density, low energy plasma inside a vacuum chamber (16) for etching metals, dielectrics and semiconductor materials. Relatively lower frequency, preferably RF frequency, auxiliary bias energy applied to the wafer support cathode (32c) controls the cathode sheath voltage and controls the ion energy independent of density. Various etch processes, deposition processes and combined etch/deposition processes (for example, sputter/facet deposition) are disclosed. The triode (VHF/UHF split electrode plus RF wafer support electrode) provides processing of sensitive devices without damage and without microloading, thus providing increased yields.

Abstract: An apparatus for transferring data in a time-sharing mode includes a plurality of modules connected to a common bus line for transferring data therethrough, a bus controller for controlling a time-sharing transfer of data between the modules, and a system controller connected to the modules and bus controller through a bidirectional command line. The system controller is operable, upon receipt of a data transfer request or data transfer completion notice from certain of the modules, to command the bus controller to generate or eliminate a bus slot. Then, the bus controller sets a new bus slot to a bus cycle, or eliminates a designated slot from the bus cycle, thereby to vary the number of slots constituting the bus cycle. Slot enable signals corresponding to the respective slots are transmitted to the modules through the bus line. Each module successively compares a slot number and slot enable signals, and exchanges data with the bus line upon agreement between the slot number and slot enable signals.

Abstract: Apparatus for the non-contact drying of a web of material with a combination of infrared radiation and heated air. The apparatus includes a dryer enclosure (10) in which is mounted a plurality of air bars (18a-n,19a-n) in air-receiving communication with upper and lower headers (14,15) both above and below the web (13) for the contactless convection drying of the web. Mounted between the air bars are infrared gas fired burners (22a-n,23a-n). In order to accommodate the infrared burners between the air bars, spacers (16a-n,17a-n) are fitted on the header system supplying air to the air bars. The drying surface of the web is thus alternately heated by infrared radiation and then scrubbed by high velocity air to remove the moist boundary layer. Since the burners are completely enclosed, all heat energy is captured in the exhaust system of the dryer assembly and a portion can be used to supply hot convection air back to the dryer. The remaining air is hot enough to be used in other convection dryers in series with the instant combination dryer, or have its heat recovered through the use of heat exchanger.
