Abstract: A microprocessor integrated circuit chip includes a plurality of functional areas containing a large number of widely distributed signal sources. An on-chip selection network is distributed on the chip which enables the selection of signals from the large number of sources under microinstruction control without any decrease in chip performance. The network includes an access bus which is distributed to the functional areas as a function of the concentration of signals provided by the sources. Individual decoders are strategically located on the chip and connect in common to a control bus. Each decoder connects to a plurality of switches for linking the sources of a functional area to the access bus. A selector circuit terminates the access bus at one end. Under microprogram control, the selector circuit is enabled to select which final source signal is applied to the functional area containing branching circuits for selecting a next microinstruction to be executed by the microprocessor.

IPC: H01H83/12

Abstract: A switch has contacts constructed so that an electro-dynamic force is created by the current flowing through the switch which tends to maintain the switch in a closed state. This force counteracts other electro-dynamic forces which tend to open the switch. The contact design is particularly adapted from use in a single pole-double throw switch having a contact arm that is movable between two fixed contacts. The electro-dynamic force compensation exists between the contact arm and whichever one of the fixed con­tacts the contact arm is against. The fixed contacts also include arc runners so that any arc that develops as the contacts separate eliminates electro-dyanmic force which tends to maintain the switch in a closed state.

Abstract: Raw feature sensors (110) are arranged in rank order for sensing raw features which exceed a respective set of raw feature values. Each raw feature sensor (110) determines if a feature exists which falls within its range. The raw feature sensors have ranges which are exponentially separated by a constant factor, which may be chosen to allow easy approximate calculation of small integer ratios or other important ratios. A contrast enhancer may be used in the case of visual data to improve the operation of the raw feature sensors. A ratio-detector network is responsive to the raw feature sensors and calculates ratios of the raw feature data. The ratio-detector network pairwise ANDs each possible pair of results from the raw feature sensors and combines these pairwise AND results with OR gates to generate a set of outputs, each of which indicates the detection of a single ratio.

Abstract: In a fuel injection system having a distribution-type fuel injection pump (1), fuel is supplied successively to cylinders (C₀-C₅) of an engine (E) from a pressurizing chamber (17) of the pump. The pressurizing chamber communicates with a low-pressure chamber (11) through a relief passageway (24a) opened and closed by an electromagnetic valve (2). During a stroke in which volume of the pressurizing chamber is reduced by each forward stroke of a plunger (13), opening and closing of the valve are controlled, to control starting timing and/or termination timing of fuel injection to the cylinders. A delay occurs in the starting timing and/or the termination timing with respect to drive pulses supplied to the valve, due to an operation delay of the valve. A plurality of memory sections (TSDV₀-TSDV₅, TEDV₀-TEDV₅) are provided for storing therein delay times for the respective cylinders. A starting point or a termination point of the drive pulse is advanced correspondingly to the delay times stored respectively in the memory sections, at fuel injections with respect to the respective cylinders.

Abstract: A reagent which can couple with the 5' hydroxy position of a nucleotide, typically the terminal nucleotide in a nucleotide multimer, under the same conditions used in known standard solid-phase nucleotide multimer synthesis. When so coupled, the reagent produces a substituted nucleotide multimer with a protected linking moiety which is deprotected under the same alkaline conditions typically used to deprotect nucleotide exocyclic amines of a completed synthetic nucleotide multimer. A single one of the class of reagents can be so coupled to any nucleotide, and since the reagents have a non-nucleotide skeleton, the resulting substituted nucleotide multimer does not have an additional nucleotide which could potentially interfere with hybridization with a target nucleotide sequence.

Abstract: On the one hand, an injection moulding method for plastic materials is specified, in which the injection mould is heated before injection of the material to a temperature lying above the melting point of the material with the aid of a heat transfer medium, preferably a liquid heat transfer medium, the flow of the heat transfer medium through the injection mould is blocked during injection, in order to additionally support the parts made with thin walls bounding the mould cavity of the injection mould, and in which, after complete filling of the mould cavity of the injection mould with material, the injection mould is cooled to a temperature lying below the freezing point of the material by the heat transfer medium flowing through. The cooling can be controlled in such a way as to compensate effectively for material shrinkage occurring upon cooling down. On the other hand, an injection mould is described, in which the mould cavity is bounded by thin-walled parts, and the through-flow channels for the heat transfer medium run on the side of the thin-walled parts facing away from the mould cavity. Two heat-transfer medium circuits are expediently provided, an inner heat-transfer medium circuit and an outer heat-transfer medium circuit, which are separately controllable in order to commence cooling away from the sprue and then proceed with the cooling gradually up to the gating bush of the injection mould in a controlled way.

Abstract: An integrated, self-aligned trench-transistor structure including trench CMOS devices and vertical "strapping transistors" wherein the shallow trench transistors and the strapping trench-transistors are built on top of buried source junctions. A p- epitaxial layer (12) is grown on a substrate (10) and contains an n-well (14), and n+ source (16) and p+ source regions (18). Shallow trenches (20, 22) are disposed in the epitaxial layer (12) and contain n+ polysilicon or metal, such as tungsten, to provide the trench CMOS gates. A gate contact region (24) connects the trenches (20, 22) and the n+ polysilicon or metal in the trenches. The n+ polysilicon or metal in the trenches are isolated by a thin layer (26) of silicon dioxide on the trench walls of the gates. The p+ drain region (28), along with the filled trench gate element and the p+ source region (18), form a vertical p-channel (PMOS) trench-transistor. The n+ drain region (30), along with filled trench gate element and the n+ source (16) form a vertical n-channel (NMOS) transistor. The PMOS and NMOS trench transistors are isolated by shallow trench isolation regions (34) and an oxide layer (38).

Celui-ci comprend des passages faisant communiquer les compartiments arrière et avant. Lorsqu'un poussoir actionné par le percuteur pousse le piston vers l'avant, le renflement percuteur déforme la paroi transversale de cuvette d'amorce (60) et provoque l'explosion de la charge propulsive (66). Les gaz de propulsion déplacent en premier le piston (54) vers l'arrière, pour dégager le boîtier de la cuvette d'amorce (60), de sorte que les gaz subissent une expansion dans le compartiment arrière avant d'atteindre l'arrière du projectile (18) dans le compartiment avant. Dès lors, le projectile est propulsé sans être rupturé.
