Abstract: A dopant-opaque layer of polysilicon (32) is deposited on gate oxide (26) on a silicon substrate (18, 20) to serve as a pattern definer. It controls successive P and N doping steps used to form operative DMOSFET regions within the substrate, a trench (63) in the silicon surface, and conductive structures (28, 30) atop the substrate. A source conductive layer 28 is deposited in the trench to electrically contact source region (24) as a gate conductive layer (30) is deposited atop the gate oxide 26. The trench sidewall (64, 65) is profile tailored using a novel O2-SF6 plasma etch technique. An oxide sidewall spacer (62) is formed on the sides of the pattern definer (32) and gate oxide (26), before depositing the conductive material (28, 32). A planarizing layer (72) is used as a mask for selectively removing any conductive material deposited atop the oxide spacer.

Abstract: A system enabling the frequency, and if desired, phase control of an oscillator which generates a standard signal useful as a carrier which is modulated by modulation signals. A multiplicity of such oscillators and associated transmitters may be used in a simulcast transmission system which covers a large area, for example in paging applications where the transmissions must be of the same frequency or with predetermined frequency offsets and be matched in modulation in order to prevent interference and distortion in areas where the transmissions from different transmitters overlap. The transmissions originate from a station which may be remote from the transmitters. The station has a system controller and the transmitters have transmitter controllers. For frequency control a reference signal generated in the system controller is transmitted over the same link and band width (e.g. the voice band width) with the voice modulating signals to the transmitter controllers of all of the transmitters. This reference signal may be corrupted by noise and other error signals. It also may be transmitted or received intermittently during periods when transmissions are quiet and traffic is light. At the transmitter controllers, multiplicities of phase measurements are made a plurality of times, each time during an interval of predetermined length and at predetermined rates. From these measurements statistical values of phase, deviations and times of occurrence are collected and used to provide error control signals in terms of the ratio of phase difference to time, notwithstanding that the reference signals may jitter in phase and amplitude due to noise and other errors and also notwithstanding that the phase measured at various of the times may include a multiplicity of phase wraps (the phase difference being greater than one cycle or 360 DEG .) A frequency error may be offset, or if offsets are not used, the frequency errors may be applied to the standard oscillator to lock the phase thereof in predetermined relationship with the reference. For modulation control, each transmitter is keyed with modulation calibration signals. These signals are transmitted to the system controller where they are correlated, and codes representing deviations from matched correlation characteristics (delay, gain and frequency spectrum) are transmitted to each transmitter where modulation signal correction circuits are conditioned to process the modulating signals so that the transmissions from each transmitter will be matched in modulation characteristics.

Abstract: A deflection yoke liner for mounting deflection coils on a cathode ray tube ; the liner has at least two interconnectable sections (30) with interengaging snap fasteners (40) in the form of a tab (50) and block (80) that position and fix together the liner sections. The tab has a stop or hook (62) adjacent a distal end for clasping over the block (80). The block (80) has an inlet groove (84) for guiding the tab (50) and thereby positioning the liner sections relative to one another. One of the groove and tab tapers inwardly and the other is complementary and tapers outwardly. Preferably the tapering sections of the groove and tab engage near a point of full abutment of the liner sections, by way of tapered shoulders (64) at the proximal end of the tab (50) and a narrowing inlet (88) taper on the block (80). The liner sections (30) are positively positioned as the tab (50) is advanced in the groove (84) until the hook (62) snaps over the abutment upon bringing together the liner sections (30). The block (80) can be discrete or formed by a continuous ridge. The block (80) and the tab (50) protrude axially above a surface of the flange (22), the tab width being oriented along a flange of the respective liner section (30). This mechanism gives an accurate and quick positionning of the supporting liner parts and finds use in deflection yokes for cathode ray tubes displays. <IMAGE>

Abstract: An improved vacuum sewerage system for transmitting sewage through an intermittently opened sewage control valve of a transport conduit by means of differential pressure. The vacuum conduit is laid out in a saw-toothed fashion, having a riser, a low point, and a downslope. When no sewage is being transported through the conduit, any residual sewage in the conduit collects in the low point, with minimal intermittent closure of the conduit over time to permit minimal drop in vacuum or subatmospheric pressure throughout the conduit such that there is more than adequate vacuum or subatmospheric pressure available to operate the control valve. When the control valve is opened, the sewage transported through the vacuum conduit forms a generally hollow cylindrical mass, which is propelled toward a vacuum collection tank. The system includes an electric air admission controller ("EAAC"), which automatically opens and closes an air control valve independently of the level of accumulated sewage upstream of the sewage control valve, in order to inject additional air at atmospheric pressure into the vacuum transport lines to apply additional fluid pressure to a mass of sewage therein, and to avoid a waterlogged condition by supplementary transport. A conduit line having more than 13 feet of total lift is thereby possible, provided that the sum of the pressure losses across all the risers equals or exceeds the sum of the minimum subatmospheric pressure condition available at the vacuum collection station minus the pressure head required to operate the control valve.
