Patent EP-0515809-A2 (EP)
Inventor: FREDERICKS EDWARD C
IPC: H01L21/20
Filed: 1992-04-10
Abstract: A method of providing sublayer contacts in vertical walled trenches is proposed. In accordance with the present invention, the phosphorus doped amorphous silicon is deposited at temperatures less than 570°C. The conversion into the extremely large crystal low resistivity polysilicon is accomplished by a low temperature anneal at 400°C to 500°C for several hours and the short RTA treatment at a high temperature approximately 850°C for twenty seconds. These two conversion heat treatments are done at sufficiently thermal budget to prevent any significant dopant movement within a shallow junction transistor. After anneal, the excess low resistivity silicon is planarized away by known techniques such as chemical/mechanical polishing. In addition, due to the trench filling abilities of the amorphous silicon CVD process, in one preferred embodiment of the invention the capability of accessing subsurface silicon layers at different trench depths is demonstrated.

Abstract: The socket is used for the connection of flat contact pins as are used in plug connecting devices for test purposes, especially in car construction. The socket (1), which allows frequent plug-in cycles with low insertion forces, comprises a contact spring support having two supporting walls (2, 3) which are essentially parallel to one another. Said walls (2, 3) are fitted, preferably on both inner sides, in each case with one row of contact springs (4) which are domed in such a manner that a gap (5) is formed by the domes which point towards one another, which gap (5) expands elastically when a flat contact pin is inserted, thus making contact. The ends (6, 7) of each contact spring (4) are bent around towards one another on the outside of the associated supporting wall (2, 3). The two supporting walls (2, 3) are connected to one another via a lateral wall (12) which determines the distance between them. A bearing wall (14) which bounds the insertion gap (5) for the flat contact pins is provided on the edges (13) of the supporting walls (2, 3) which are placed on the lateral wall (12).

Abstract: The invention relates to a multiantenna VHF receiver, the RF signal received by each antenna being mixed in a mixing stage assigned to the respective antenna with a signal of a first oscillator, generated in the receiver, and the mixed signals thus obtained, with controllable phase position, being added to form an aggregate signal. The alternative frequencies supplied by an RDS demodulator are stored. One of the mixing stages is used briefly at predetermined points in time for updating the stored frequencies with the associated values for the level of reception quality. If they fall below a predetermined level of reception quality, the receiver switches over to a stored alternative frequency which is accepted as suitable for reception. <IMAGE>

Abstract: 5 n7 A modular ATE system includes a plurality of test modules and a receiver for use with a variety of fixtures to which printed circuit boards are to be coupled. Each test module includes a plurality of pin cards controlled by a single module controller. Multiple test module are included for testing a variety of functions. Test signals are generated by discrete sets of pin cards and controllers, then output to the receiver for interconnection to a fixture and printed circuit board(s) under test. A substantially wireless receiver is provided, including a translation board for electrically coupling test module pin cards to the fixture. By eliminating wiring and cabling by using a prefabricated translation board, noise is substantially reduced and test signal quality improved. The translation board defines prescribed signal mapping for interconnecting the I/O pins of ATE pin cards to the underside of the fixture. Different translation boards may have different mappings. The ATE can be adapted for use with fixtures having different underside layouts by changing the test modules and/or the receiver. As a result, the ATE can be adapted to emulate many conventional ATE's which are limited to a fixed fixture underside layout.

Abstract: The injector (10) for intermittently injecting fuel under high pressure in an internal combustion engine is provided with an injector valve member (18). The movement of this injector valve member (18) to open and close a fuel discharge orifice (24) is controlled by the fuel pressure in a control chamber (40) acting on a valve piston (26) on the side opposite to the discharge orifice (24). A cylindrical member (36) surrounds the upper part (30) of the valve piston (26). Energization of a solenoid (44) results in the opening of a pilot valve (46) and a subsequent quick drop of the fuel pressure in the control chamber (40). The solenoid (44) in addition to its function as a high speed actuator for the pilot valve (46) is also used to carry and transmit the force resulting from the fuel pressure in the control chamber (40) and acting on the cylindrical member (36), on the solenoid (44) and on further members (48, 50, 52, 14). Since the solenoid (44) can therefore be mounted directly within the injector housing (14), the design of the injector (10) can be very compact and simple.

Abstract: An improved sample and hold signal generator produces very short delay intervals between successive sample-to-hold transitions that are both collectively and individually adjustable. A plurality of capacitors (C₀, C₁A-C n A, Q c ) are charged to a precharge level (V₁-V n,   v c, V p ) upon the occurrence of a precharge signal and discharged to the threshold level (V th ) of a plurality of amplifiers (A₁-A n , IA₁, A st ) through a plurality of constant current sources (Q cs1 -Q csn , Q₂, Q₂') upon the occurrence of a discharge signal. When the voltage (V₁-V n,   v c, V p ) on a particular capacitor (C₀, C₁A-C n A, Q c ) is discharged to the threshold level (V th ), the associated amplifier (A₁-A n , IA₁, A st ) produces a sample-to-hold signal transition and the voltage level of a signal being sampled is stored on a capacitor (C₁B-C n B, C₁,C₂). In successive cells (HGC x ) of the sample and hold generating means the threshold level (V th ) is reached at incrementally varying delay times (t₁-t n ) that are separated by approximately equal time intervals (Δt). Varying the precharge voltage (V₁-V n,   v c), the constant current that discharges the capacitor (C₀, C₁A-C n A, Q c ), and, in one version, the threshold (V nl1 -V nln ) of non-linearity of a non-linear capacitor (source-drain coupled MOS FET transistor(Q c )), can be used in different combinations to control the timing of individual cells or the delay of the whole set of cells.

Abstract: In the field of, e.g., mail processing apparatus, it is known to provide encoding marks on settable members such as thumbwheels for setting the date to be printed on envelopes. The encoding marks in known apparatuses are detectable by retro reflective sensors to determine the setting of the settable members. 
     Previous such apparatuses are disadvantageous because it is necessary to provide a sensor circuit and a set of encoding marks for each thumbwheel, etc. Thus, the arrangement is complicated and the processing of the resulting signals time consuming. 
     The disclosure relates to a settable apparatus for use in a mail processing apparatus, in which at least one settable member (10) includes encoding marks such as digits marked thereon. A charge coupled device (17) is arranged to detect the encoding mark of one or more settable members simultaneously. A lens (18) is disposed between the settable member and the charge coupled device to focus the image of the encoding marks onto the surface of the charge coupled device. 
     Thus, the settings of a number of settable members such as thumbwheels may be determined simultaneously. 
     An optional feature of the invention is a shutter which may be closed across the charge coupled device to protect it from damage, dust contamination etc.

Abstract: A pair of plastic tubes are welded together by mounting each tube in the clamp jaws of a holder. A heated wafer is movably mounted in the gap between the tubes to cause the ends of the tubes to melt. The melted ends of the opposed tubes are pressed into contact with each other to form a welded connection. Each side of the wafer has a scoop to remove excess plastic material at the ends of the tubes to control the size of the weld connection. A pair of structural cam elements is used to create a precise spacing between each set of clamp jaws for guiding the wafer to control the plastic volume of the weld. The resulting weld is independent of rheology of plastic. The same device could also be used for disconnect purposes by cutting through a single tube and forming two tube sections. Unique double jaw construction is also disclosed.

Abstract: An equalization technique for the compensation of degradation caused by multipath Rayleigh fading channels to the transmission of digitally modulated signals such as -. Differential Quadrature Phase Shift Keying (DQPSK) modulated signals. The technique is applicable to both linear and nonlinear transversal equalizers. Based on the Method of Projection onto Convex Sets (POCS), the technique is realized in an iterative form. The convergence speed of equalization depends on the magnitude of a look-back parameter, and is comparable to the speed of recursive least square based equalizers. The computational complexity of the technique also is variable and is adaptable to the convergence speed requirements. For achieving convergence speeds as recursive least square techniques, the computational load required of the presented equalization is of the order of the load required of the recursive least square techniques, but its program implementation is exceedingly simpler. At the same time the code size, memory and power consumption requirements are lower.

Abstract: The present invention provides real time call control within a telecommunications network, using a call selection processor separate from the switches carrying the call, which responds to incoming calls and uses information carried in the associated signaling messages to determine what application processor, if any, should be involved on the call. One embodiment of the present invention includes a call selection processor called a signaling director", or "SD" for short, for recognizing certain signaling messages, typically SS7 initial address messages (IAM's), as the messages flow through the signaling network. Alternatively, particular signaling messages may be recognized in a signaling message processing element within the signaling network, such as the signal transfer point (STP) associated with the switch that receives the telephone calls, and a copy of those particular messages forwarded to the SD.
