Patent EP-0332345-A2 (EP)
Inventor: GAY STEVEN LESLIE
IPC: H04Q3/42

Abstract: In a private telecommunications network, a plurality of digital PBXs are interconnected via pairs of codecs. The codecs of each pair, or "tandem", are each operative to encode 64 kilobit/second (kbps) mu-law speech so as to compress it to 16 kbps speech for transmission to the other codec in the tandem. The latter is operative to thereafter decompress the 16 kbps speech back to 64 kbps. Each codec has a second mode of operation in which, rather than decode the encoded speech, it preserves the bits thereof in its own output signal. The codec transitions to this mode whenever it recognizes the presence of another codec on its high-bit-rate side of the connection. As a result, only one encoding/decoding cycle is performed across the connection, thereby minimizing the speech-coding-induced distortion and delay therein. The mechanism enabling a codec to communicate its presence to another codec on its high-bit-rate side of the connection is based on the transmission of predetermined synchronization patterns inserted in the signals it outputs in that direction. In a second embodiment, codecs of the above-described type are used in a cellular mobile radio telecommunications system.

Abstract: A composite comprising a polyarylate or an aromatic polybenzimidazole article and a coating on at least one surface of the article comprised of a blend of from about 5 to about 95 weight percent of a polyarylate and from about 95 to about 5 weight percent of an aromatic polybenzimidazole. A process for preparing the composites comprises dissolving in a mutual solvent from about 5 to about 95 weight percent of the aromatic polybenzimidazole to about 95 to about 5 weight percent of the polyarylate, based on the total weight of those polymers, heating a polyarylate or aromatic polybenzimidazole article to a surface temperature over 100°C., e.g., from about 120°C. to about 180°C., and then coating the polyarylate or aromatic polybenzimidazole article with the solution and subsequently evaporating the solvent, thereby producing a dried coating of a blend of a polyarylate and an aromatic polybenzimidazole on at least one surface of the article. The composites, particularly in the form of films, fibers or fibrets, may be post-treated with heat or sulfuric acid in order to minimize their shrinkage when subsequently subjected to heat and in order to increase their resistance to solvents and acid.

Abstract: A multi-step plasma etch method for etching a tapered via having uniform bottom diameter ("CD") and extending through the resist and into the oxide layer of a coated semiconductor substrate, and a coated semiconductor substrate whose coating has been plasma etched to define such a tapered via. The first step of the inventive method is an anisotropic oxide plasma etch operation, preferably employing a plasma consisting primarily of CF₄, which produces a non-­tapered via having diameter substantially equal to CD and extending through the resist and into the oxide layer. A preferred embodiment of the inventive method includes a second step defining an upper sloping via portion without significantly increasing the diameter of a lower portion of the non-tapered via. This second step is a tapered resist plasma etch operation employing a mixture of oxygen (O₂) and CF₄. The slope of the upper sloping via portion may be controlled by varying the ratio of oxygen to CF₄. In an alternative embodiment, the method produces a "stepped" via having an upper non-tapered portion which extends through the resist and has an opening diameter substantially greater than CD, and a lower non-tapered portion which extends through the oxide and has diameter substantially equal to CD. This embodiment includes an isotropic resist plasma etch operation which enlarges the diameter of the upper via portion extending through the resist, but does not significantly enlarge the lower via portion extending into the oxide layer, followed by an anisotropic oxide plasma etch operation which vertically erodes the lower via portion extending into the oxide layer, and which may also increase the via depth to the desired total depth. Preferably, the   plasma used in the isotropic resist plasma etch step consists primarily of O₂ and the plasma used in the subsequent anisotropic oxide plasma etch step consists primarily of CF₄.

Abstract: This invention relates to a digital modulating method used for recording PCM audio signal, computer data, and etc. on a recording medium such as optical disc. The digital modulating method is constructed so that the minimum length between transition could be the maximum in encoding M bits into N bits (M < N), and can generate clocks with simple circuit arrangement by satisfying the relationship N = α M, where α is an integer equal to or larger than 2. 
     Further, by converting a predetermined unit of input data into a first code signal according to substantially the same conversion rule and selectively adding coupling bits of different bit number to each junction between a first code signal and an adjacent such signal, the digital modulating method is adaptable for various transmission systems with a simple arrangement.

Abstract: The present invention is a system that updates a pressurized water reactor core model, or data file describing the core, periodically using measured values determinable from core instrumentation. The system starts with a calibrated model (62) calibrated from a flux map and a boron concentration measurement both determined monthly (60). Reactor system measurements are performed and the model is updated from the measurements using a standard depletion calculation (66). Some of the measured values are also used to determine measured actual values of axial offset and pinch (70). Standard neutronics equations are used to calculate analytical values of axial offset and pinch from the model, and the measured and calculated values are compared. If a deviation beyond a certain magnitude is detected, buckling coefficients in the model are adjusted to compensate for model drift. The updated model is stored (74) and a time-out (76) period is entered until it is time for another drift compensation cycle to start. The adjustment overcompensates the coefficients until the difference between the measured values and calculated values is slightly less in magnitude than the deviation but of an opposite sign. The adjusted and updated model can be used for accurate initial values of a core predictor or for display to the operator.

Abstract: An electronic clock has a single Josephson junction connected in parallel to a resonant circuit, which is a delay line with a matching resistance at the input end to provide series termination. The opposite end of the delay line is an open end to reflect pulses, and the pulse transit time on the line determines the clock rate. A zero crossing detector is provided to initiate the clock operation when an input signal rises above a given threshold, and a reset circuit is included to turn off the clock when the input signal falls below this threshold. A flip-flop circuit allows the clock to be turned on by alternate initiating signal pulses. A modification includes a pulse rejuvenating circuit at the end of the delay line to offset pulse degradation. All of the circuits are fabricated with Josephson junction elements, and the zero crossing detector, reset circuit, flip-flop circuit and pulse rejuvenator circuits include dc-SQUID's. The clock is capable of operation at frequencies up to 100GHz and can sample input single frequencies as high as 15GHz.
