Patent EP-0458490-A2 (EP)
Inventor: PATEL ARVIND MOTIBHAI
IPC: H03M5/14
Filed: 1991-05-09
Abstract: A signal processing channel and method are described for processing digital sample values corresponding to an incoming analog signal representative of coded binary data. An eight-sample look-ahead algorithm is used to precompute the values of functional expressions for a baseline check and for a peak-position check. These precomputed values are compared against appropriate thresholds to provide respective binary decision outputs which, with state values corresponding to the current state, are used to determine state values for the next state, which become the current state values for the next iteration of the clock cycle. During each of a series of successive clock cycles, one successive bit of coded binary data corresponding to said current sample value is decoded, and at the next clock cycle, the computed next state becomes the new current state. 
     Sensitivity to missing or extra-bit errors is minimized and full advantage of a (1,7) run-length-limited code constraint is achieved. A phase check is not necessary.

Abstract: The press device for pressing together workpieces has two press units (3, 5) which can be pressed against one another and mounted in an articulated manner on in each case one of the two legs (18a, 18b) of a C-shaped force-absorbing unit for absorbing the reaction forces. One press unit (3) is firmly connected to the machine frame (1) and the other press unit (5) is displaceable in the feed direction (7) on guide rails (8a) fixed to the machine frame (1). Although, as a result of this arrangement, the legs (18a, 18b) of the C-shaped force-absorbing unit can be bent up due to the feed pressure during the pressing-together, tilting or inclination of the press rams (11, 12), mounted on them, of the press units (3, 5) does not occur. The press device can be used wherever the two press rams (11, 12) of the press units (3, 5) have to be moved towards one another under high pressures and in exact alignment and lateral feeding of the workpieces to be pressed is to be possible. Consequently, it can be used in flash butt-welding machines, pressure-welding machines, ... and also in machine tools, such as, for example, drilling machines, milling machines, and in a large number of presses and the like. <IMAGE>

Abstract: A diskette container for receiving a compact disc with a flat housing, comprising a bottom plate and a top plate. The diskette container has a disc carrier, which can be displaced in the manner of a drawer against the force of a spring. The spring is a spring clip, which is arranged transversely to the direction of displacement of the disc carrier and acts on the underside of the disc carrier. When the disc carrier is displaced, the spring clip passes over a dead centre, after which it then takes the disc carrier along with it until it reaches its relaxed position.

Abstract: A method for treating wastes from working ferromagnetic materials is proposed. In this method, the wastes are mixed in a first vessel with a washing solution, and the oil or the oil-water emulsion adhering to the wastes is dissolved. In this vessel, the ferromagnetic constituents of the wastes are then separated by means of a magnetic field, and the further constituents are subjected to a second washing step in the next vessel. The ferromagnetic constituents are fed to a further vessel and likewise subjected therein to a second washing step. The separated and deoiled constituents can then be filtered out of the appropriate washing liquids in suitable filter devices. <IMAGE>

Abstract: A BICMOS passgate circuit (PSGT3) (PSGT3A) for use in latches and flip-flops incorporates a bipolar output circuit (Q1,Q3) comprising a bipolar pullup transistor element (Q1) and a bipolar pulldown transistor element (Q3) coupled to the passgate output (V OUT ) for transient charging and discharging of load capacitance (C L ) at the passgate output (V OUT ). The bipolar output circuit provides increased sinking and sourcing output drive current and ß amplification of sinking and sourcing drive current at the passgate output V OUT  in response to data signals at the passgate input (V′ IN ) in the transparent operating mode.

The MOS input logic circuit (QP3,QP4,QP5,QP6,NAND1) is coupled to the bipolar output circuit (Q1,Q3) and is constructed to control the conducting states of the bipolar pullup (Q1) and pulldown (Q3) transistor elements for transient turn on of one of the respective bipolar pullup and pulldown transistor elements during respective switching transitions at the passgate output (V OUT ). The MOS input logic circuit is also connstructed for turn off of the bipolar pullup (Q1) and pulldown (Q3) transistor elements follow switching transitions at the output (V OUT ) and during the blocking operating mode. A final latchback circuit (LTBK2) (INV3,INV4) is coupled to the passgate output to latch an output data signal and for pulling up the final output (V OUT ) to a high potential level power rail (V CC ).

Abstract: An ultrasonic Doppler imaging apparatus emits ultrasonic pulse waves to an object body under test and provides information on blood flow in the body based on Doppler shifts of ultrasonic waves reflected back from the object body. The ultrasonic pulse waves emitted by a probe (1) to the object body undergo Doppler shifts by being reflected by the blood stream, and the reflected ultrasonic waves received by the probe are decomposed with an A/D converter (8) in synchronism with emission. The decomposed data are transformed into complex Doppler data through a quadrature addition/subtraction by quadrature addition/subtraction means (9). The complex Doppler data is subjected to frequency analysis through the correlative computation or the like, and resulting data is stored in a frame memory (16) and displayed. The apparatus is capable of measuring the Doppler shift frequency accurately.

Abstract: An etch stop layer of chromium (24) is initially deposited on the circuit elements of the CMOS silicon substrate. Next, a conductive layer of tungsten (26) is non-selectively deposited on the chromium layer (24). A photoresist mask (28) is then lithographically patterned over the tungsten layer (26). The tungsten layer (26) is then etched down to, and stopping at, the chromium layer (24), after which the photoresist mask (28) is stripped. The stripping preferably uses a low temperature plasma etch in O₂ at a temperature of less than 100°C. Finally, a directional O₂ reactive ion etch is used to remove the chromium layer (24) selectively to the silicon substrate.

Abstract: This invention encompasses using anisotropic plasma at a low temperature to strip resist from a semiconductor wafer. A semiconductor wafer  10  is placed in a reactor  26  which contains an oxygen plasma source  28 . The oxygen plasma source  28  emits oxygen plasma  32  which is drawn towards the biased wafer  10 , exposing the resist layer  22  of the wafer to anisotropic oxygen plasma. A sensor  30  detects when the ashing of the resist is complete, and then the plasma source is turned off. 
     Advantages of the invention include the ability to remove resist from wafers without damaging polymeric dielectric layers, which are sensitive to the harsh effects of traditional resist removal methods. With the present invention, very little damage occurs to the material on the sidewalls of vias.
