Patent EP-0510976-A2 (EP)
Inventor: HERSHBERGER DAVID L
IPC: H04N21/61
Filed: 1992-04-23
Abstract: A multiple section cable equalizer with a signal level detector (700-800) produces a clipping control signal (4) for amplifiers in each equalizer section (200,220,240), so that a variable level input signal (5,6) is restored to an equalized output signal (87,88) that is free of distortion and attendant bit errors. A fixed reference clipping stage (300) after the last equalizing stage (240) produces a signal clipped to a final output level. A feedback path (500,600) restores DC and low frequencies lost due to AC coupling. A test output stage (400) permits monitoring (110,111) of the operation of the equalizer stages (200,220,240). The signal level detector contains (in series), a differential amplifier (700) with low pass filtering (R22,C1,R18), a balanced modulator detector (710), a voltage amplifier (720), a comparator and peak detector (730,CX4), a transconductance amplifier (740) and a plurality of current mirrots (750,760,770,800) operatively connected to determine a difference current (59) from the output (48,49) of the transconductance amplifier (740) and convert this to a clipping control signal (4) voltage level. A defeat comparator (790) monitors the output (37) of the comparator and peak detector (790) and replaces the variable difference current (59) with a fixed reference current (800) when an external capacitor (CX4) used by the peak detector (730) appears to be shorted.

Abstract: In a process for manufacturing a semiconductor device having a multi-layer wiring structure, a silicon oxide film is deposited on the surface of second level wiring conductors formed on a power supply layer for electroplating, and then, the deposited silicon oxide film is etched back so that the silicon oxide film remains only on the side surfaces of the second level wiring conductors. Thereafter, the power supply layer is removed by the sputter etching, and the silicon oxide film is etch-removed together with the metal deposit adhered to the surface of the silicon oxide film at the time of the sputter etching. Accordingly, the short-circuiting of adjacent second level wiring conductors which would be caused because of peeling-off of the metal deposit is prevented.

Abstract: A ball joint assembly (5) includes a ball stud (7) and bearing sub-assembly (9) that is economical to manufacture, strong, durable and long-lasting. The bearing is molded directly on the ball surface (15) of the ball (6), thereby eliminating the need for precise tolerances in machining the ball.

Abstract: The cutting head (8) is displaceable in the longitudinal and transverse direction over a machining table (1) along a cutting bridge (7), in turn displaceable along cross guides (6), in order to cut out parts (4) from flat material (3). The flat material or the parts lie on a supporting grid (2), and a second supporting grid (2) can be unloaded during the machining operation and be loaded with a new plate (3). The two supporting grids (2) can be moved into any desired position. In particular, both supporting grids can be removed from the machining table (1) in order to make its inner space accessible and free. By means of a rotary spindle (13) mounted on the table frame, a tube or profile can then be fed from a loading device (15) through the hollow rotary spindle and can be machined. The machining installation is consequently very versatile, permits efficient machining and, owing to good accessibility, permits easy work when changing over from one mode of operation to the other. The laser beam can preferably be guided by a movable scissor arrangement with tubes of constant length, whereby the optical distance between laser source (9) and cutting head (8) can be kept constant. <IMAGE>

Abstract: In modern mercerising processes, strong liquor is applied to the moist, mechanically dewatered cloth by the addition method and becomes mixed with the water already in the cloth to produce a liquor which has the desired concentration. The recirculating strong liquor is replenished by admixture with fresh liquor of a high concentration and with weak liquor from downstream stages. The object of the invention is to reduce the consumption of caustic while maintaining an exactly uniform loading density. To this end, the moist or dry cloth is preimpregnated with weak liquor before the strong liquor is applied. The loading density of the preimpregnated cloth is continuously measured, as are the volume stream of weak liquor being added while the volume of the strong liquor is kept constant, and the concentration of the weak liquor. The volume stream of the high-concentration liquor to be added is controlled according to the NaOH balance on the basis of the measurements obtained.

Abstract: A video tape recorder (10) includes first and second magnetic heads (12a, 12b) to which reference pilot signals f₁ and/or f₃ produced by a programmable counter (14a) and reference pilot signals f₂ and/or f₄ produced by a programmable counter (14b) are applied, respectively, in a recording mode. In a reproducing mode, the reference pilot signals are reproduced and applied to mixers (28a, 28b) to which the reference pilot signals reproduced by the programmable counters (14a, 14b) are also applied. Therefore, frequency reference signals between the reproduced reference pilot signals and the produced reference pilot signals are outputted from the mixers (28a, 28b) and applied to amplitude detectors (34a, 34b, 34c, 34d) via bandpass filters (30a, 30b, 32a, 32b). A level difference between levels detected by the amplitude detectors (34a, 34b) is evaluated by an operational amplifier (38a), and a level difference between levels detected by the amplitude detectors (34c, 34d) is evaluated by an operational amplifier (38b). On the basis of the level differences, it is possible to determine whether or not index signals are recorded.

Abstract: A mounting (20) which provides superior isolation yet which eliminates damaging edge-induced shear strain (ENT) buildup in the elastomer sections (28) and (30) when exposed to high temperatures by having a first elastomer section (28) loaded in compression and a second elastomer section (30) loaded in shear. Exposing the mounting (20) to elevated temperature environments allows the first elastomer section (28) to expand in height and places the second elastomer section (30) in shear to accommodate the height change. The instant invention compensates for fluid and elastomer expansion due to high temperatures by providing a mechanical type compensator (37) which takes up less space and eliminates the pressure loss associated with air-charged compensators (99). Further, a unique combination of fluorinated fluids and polysiloxane polymer enables the mounting (20) to withstand temperatures of greater than 200 deg F for extended periods of time.

Adjacent to the insulative layer of ceramic is a layer of conductive metal (24) vapor deposited onto the ceramic.

On top of the layer of conductive material is a lead frame (34) separated by a layer of insulative polyimide material. The polyimide material has a plurality of holes filled with a conductive material (38), which electrically couple the layer of conductive material with the leads of the lead frame. The power and ground pads of the integrated circuit are connected to the layer of vapor deposited conductive material and conductive plate, which are also coupled to the corresponding leads of the lead frame, thereby connecting the IC to the leads of the lead frame. The signal pads of the IC are connected to the lead frame and/or signal lines formed within the layer of vapor deposited conductive material. The IC and attached circuit package can then be encapsulated in a plastic shell.

Abstract: A method and system for gamut-mapping color images from device-independent form to device-dependent gamut in a Cartesian color space. Digital images are mapped to any device-dependent gamut in a manner that minimizes the human visual response both to the luminance and the chrominance changes necessary to force out-of-gamut pixels into the specified device-dependent gamut. A "neighborhood gamut mapping" technique considers the subjective visual effects of nearby pixels on the mapping of each pixel. Image luminance is biased toward the luminance in the device-dependent gamut at which the greatest chroma-magnitude is available for a fixed hue angle. The chrominance of the mapped image is thereby imperceptibly adjusted to compensate for the human visual effects of luminance changes. Spatial filtering exploits the differing spatial frequency regions of insensitive human visual response to both luminance and chrominance changes.
