Abstract: A sinker is P which is self-aligned with the oxide isolating trench which is used to define the tub in which the complete bipolar device is located. In a preferred approach to the process for forming the sinker of this invention, an initial definition of the isolating trench only cuts the trench down to the top surface of the buried layer. The walls of the trench are doped, and the sinker diffused laterally through the sidewalls of the trench so that a sinker that is self-aligned with the isolating trench is created from the surface of the epitaxial layer in which the remainder of the bipolar device has yet to be defined down and into the buried layer. The trench is then defined for the remainder of the desired depth down through the buried layer and into the substrate layer below the buried layer. Thereafter, the device is formed in the tub preferably with the collector adjacent the trench and thereby aligned with the sinker. By following this sequence, little additional diffusion of the sinker occurs during subsequent processing, whereby an effective sinker, aligned with the collector of the bipolar device, is achieved without additional masking steps. 
     In an alternative approach, a hole may be cut in the surface oxide to define the area where the trench will be cut, but cutting of the trench is preceded by a diffusion of the sinker through the same hole. The sinker diffuses downward through the epitaxial layer to the buried layer, and also diffuses laterally to extend somewhat beneath the oxide immediately adjacent the trench and beyond the region where the trench will be defined. The trench is then cut in a single step through the epitaxial layer and the buried layer and into the underlying substrate, cutting directly through the region in which the sinker has been previously diffused. However, because of the lateral diffusion of the sinker, a portion of the heavily doped region which shall   function as the sinker remains, now self-aligned with the edges of the tub defining trench.

Abstract: Type III TGF-β receptor is identified in and purified from normal human embryonic palatal mesenchyme (HEPM) cells and the purified product characterized structurally and functionally. HEPM cells were found to express high levels of the type III TGF-β receptor and were found to significantly down-regulate two classes of TGF-β receptor binding site. Purification of the type III TGF-β receptor from solubilized HEPM cell membranes by affinity chromatography yielded a biologically active protein of about 205 kd which specifically binds both the recombinant and natural forms of TGF-β1 and TGF-β2, with affinity dissociation constants in the picomolar range.

Abstract: The distribution nozzle for attaching to the outlet opening of a mixing head 1 for liquid plastic mixtures, particularly for polyurethane, serves for continuous surface coating, preferably on a continuously moving substrate, the inner space of the distribution nozzle being bounded by two side walls. This inner space is designed in a simple way as an essentially smooth and straight gap 9, which is open on its narrow sides, the contour of the side walls 7, 8 being designed in such a way that the liquid plastic mixture is distributed as evenly as possible or in accordance with a predetermined pattern in the application plane. The distribution nozzle with its smooth gap without any internal fittings has a high service life, since it does not tend to clog and, in a surprising way, produces a very wide fan for the emerging plastic mixture, so that in by far the most applications the distribution nozzle no longer has to be moved back and forth over the substrate web in order to ensure coating over the entire width of the substrate web. <IMAGE>

Abstract: A system is disclosed for measuring and correcting for waveform modulation errors in a radar system employing FM signals and a digitally controlled waveform generator (58). The system relies on the assumption that the transmitter and other waveform phase and amplitude error contributions are slowly varying with respect to the radar mode data collection time and that instantaneous pulse-by-pulse correction is not necessary. During a calibration mode, a small portion of the transmitter output is input into the receiver (100) and mixed with the waveform generator signal, with the waveform modulation being removed from the mixer signal, such that the mixer signal is at a constant IF but with phase and amplitude variations that result from the distortions. The radar digital processor (120) measures these distortions, and during normal radar operation predistorts the waveform generator signal with phase distortions in antiphase with the measured distortions to compensate for the measured distortions. Amplitude distortions are compensated by control of a variable attenuator device (64). As a result, the system compensates for the exciter and transmitter distortions as well as distortions introduced by the receiver input circuitry.

Abstract: Primary (101) and secondary (102) data are communicated from a transmitter to a receiver in a communication system. The value of an individual primary data word is communicated by transmitting an individual one of a first plurality of channel symbols associated with that value while the value of a combined data word comprising an individual primary data word and an individual secondary data word is communicated by transmitting an individual one of a second plurality of channel symbols associated with that value. In the receiver, both the primary and secondary data word values are recovered from the channel symbols thus transmitted. The approach of alternating two sets of channel symbols for transmission depending on the data word size can further apply to data communications at various fallback speeds.

Abstract: A two-step process for characterization of peaks in a chromatogram is disclosed. In a first step, data corresponding to each peak or each pair of peaks in the chromatogram is identified. A unique filter apparatus locates extrema of the curvature of the chromatographic data and a data file is generated containing characteristics of the extrema. A pattern recognition apparatus analyzes the characteristics of the located extrema and classifies the peak or peak combination represented by the data in the file as one peak or peak combination in a set of resolved peaks and selected combinations of resolved peaks. A portion of the chromatographic data, which corresponds to the peak or peak combination identified by the pattern recognition apparatus, is identified. This portion of the data includes both the signal for said peak and the signal for the baseline upon which the peak is superimposed. 
     In the second step, data for a peak or a peak combination identified as described above, or in the alternative, identified by some other process, is processed and a set of characterizing parameters for the peak or the first peak in the peak combination is generated without a prior baseline correction to the data. The peak data including the baseline level upon which the peak is supenmposed is analyzed using one of lookup tables, neural nets, curve fitting, or combinations of lookup tables, neural nets and curve fitting. Each of these characterization processes, using information about the peak crest and the peak inflection points, determines a set of characterizing parameters and a baseline estimate that best fit the identified data. Thus, the peak characterization according to the principles of this invention is not biased by a prior baseline correction.
