Patent EP-0381325-A2 (EP)
Inventor: ARNOLD SCOTT
IPC: G06F9/46
Filed: 1990-01-12
Abstract: A synchronising scheme for processing "locked" memory access requests from various computer system units is provided by a System Control Unit (SCU) (14). The SCU is provided with a directory of lock bits in such a way that each memory address associated with a memory access request is mapped to a corresponding location in the lock directory. Incoming requests for a given memory location are processed by interrogating the corresponding lock bit in the lock directory. If the lock bit is not set, the request is granted. The lock bit is subsequently set and maintained in that state until the unit requesting the lock has completed its memory access operation and sends an "unlock" request. If the interrogated lock bit is found to be set, the lock request is denied and the requesting port is notified of the denial and requested to try again. Fairness is incorporated in the processing of denied lock requests by means of a reserve list onto which denied requests are sequentially positioned on a first-­come-first-served basis.

Title: Overhead optical transmission system
Inventor: ROWLAND SIMON MARK
IPC: H02G7/20
Filed: 1990-06-14
Abstract: In an overhead optical transmission system in which an optical cable 1 is freely supported between towers employed to support overhead electric power transmission lines and in which each end of the suspended length of optical cable is secured to a tower by means of a metal termination fitting 3 which surrounds and is clamped on a part of a length of the optical cable at or near this end, each metal termination fitting of the cable over a part of the length of the fitting extending to the end of the fitting remote from the tower and an immediately adjacent part of the length of the optical cable are surrounded by a shield 6 of an electrically conductive metal or of a semi-conductive plastics material sufficiently conductive to reduce arcing and/or joule heating. Preferably, a preformed helix 8 constituting a damper extends lengthwise of the shield and may extend lengthwise of the part of the length of the fitting 3, the overall outer diameter of the preformed helix over a part of its length remote from the fitting increasing smoothly in a direction away from the fitting. Where the shield 6 is a preformed helix of a semi-conductive plastics material, the preformed helix may be so shaped over a part of its length remote from the fitting 3 that the preformed helix serves the dual purposes of a shield and a damper.

Abstract: An electrical appliance such as a vacuum cleaner has a power outlet socket (18) to which an accessory such as a drill or sander is connectable, and a power control circuit which senses flow of current through the power outlet to the accessory (22) so as to actuate a switching means (TR) for supplying current to a load (M2) of the main appliance. A delay means (C1, R3) causes the switching means (TR) to continue supplying current to the load (M2) of the main appliance for a predetermined period after the flow of current to the accessory (22) ceases. Thus the accessory may be switched on using its own manual switch (28), in response to which the control circuit energises the main appliance itself and maintains this appliance energised for a period after the accessory is switched off.

Abstract: A high value, precision resistor (10) includes a doped region (18) having a boustrophedonic (folded or meandering) shape formed in a substrate (12). At least one section of the doped region (18) is formed by implantation using a focused ion beam. Where the entire doped region (18) is formed by the focused ion beam, the length thereof is selected to be large (10 to 100 times the width of the boustrophedonic shape) to maximize the accuracy of the resistor (10) by averaging over variations in grain sizes and implant dose. Alternatively, a probe resistor (32) and a plurality of similar unconnected doped sections (28) may be formed by means such as photolithography and flood ion implantation. The probe resistor (32) is measured at the desired operating temperature to determine the ratio of the measured resistance to the desired design resistance value. The unconnected doped sections (28) are then interconnected by plugs (40, 42, 44, 46), formed with a focussed ion beam, to program the fabricated resistor to exactly the designed resistance value at the desired operating temperature.

Abstract: When a moving image is processed, after an input video signal is supplied to an image inputter, the image inputter time-divisionally converts the input video signal to a digital signal and outputs a control signal such as a vertical synchronous signal. A multiplexer reads image data converted by the image inputter into the digital signal and stores them into a plurality of temporary storers unique for frames according to the control signal from the image inputter. The plurality of temporary storers are respectively connected with a plurality of processor elements. The plurality of processor elements process the memory contents of the plurality of temporary storers and re-store the processing results back in the plurality of temporary storers. A multiplexer sequentially retrieves the memory contents from the plurality of temporary storers, and has an image outputter for converting a digital signal to a video signal output them. An addition of a switch signal generator for generating from the control signal a switch signal for dividing a frame enables the frame to be divided into a plurality to be stored in the plurality of temporary storers, thereby allowing the plurality of processor elements to independently perform their processes in parallel. An arbitrator judges whether or not the plurality of processor elements have completed their processes. If the processes are incomplete, the arbitrator delays the multiplexer in retrieving the memory contents from the plurality of temporary storers.

Abstract: An apparatus for the quantitative determination of individual components of optically active substances comprises two light-emitting diodes (1, 21), a polarisation filter (31), a collimator lens (32), a twin-compartment cuvette (10;14,15) which is filled with a dialysate (11) and a reference liquid (11'), an analyser (36), and line detectors (54, 64) with downstream measuring and analysis electronics (39). The pulsed light of the light-emitting diodes (1, 21) is linearly polarised by the beam splitter cube (31). The resulting polarisation directions differ by 45 degrees. The polarisation direction of the analyser (36) is essentially perpendicular to the polarising cube (31) so that the radiation of the two light-emitting diodes (1, 21) which passes through an optically non-rotating reference liquid (11') generates an identical photosignal in a pulsed manner in the line detector (64). In contrast, the polarisation of the radiation passing through an optically rotating dialysate (11) is rotated further in the same direction, so that the line detector (54) receives two different photosignals from the light-emitting diodes (1, 21), the comparison of which signals permits inferences regarding the concentration of optically active substances. As a result of the dispersing effect of the prismatic cuvette (10:33), enhanced by a wedge (38) and a grating (37), the extinction and the optical rotation can be resolved spectrally, which makes it possible, based on the dispersion, to measure the concentration of individual optically active substances and thus to determine the desired signal by correction calculations from the total optical rotation signal. <IMAGE>

Abstract: A vehicle transmission system having shift levers (92,96) coupled to couplers (65,55) for selection of ranges of gear speed ratios and electro-hydraulic powershift clutches (60) for selection of a gear speed ratio within the selected range is provided with controls for avoiding unexpected speeds or speed changes under certain conditions. If the vehicle is moving at start-up as a result of a stall or accidental reset of the microprocessor (80), and the shift levers (92,96) have not been moved since the stall or reset, the microprocessor retrieves from a non-volatile memory an indication of the last selected powershift gear prior to the reset and uses it for the initial powershift gear selection. When an operator depresses a clutch (79), shifts a shift lever (92,96) and then changes his mind and shifts the shift lever back to its original position before releasing the clutch above a threshold point, the microprocessor (80) selects the powershift gear in effect at the time the clutch pedal was depressed.

Abstract: A memory (20) for performing read cycles and write cycles has memory cells (30) located at intersections of word lines (32) and bit line pairs (34). A write control circuit (44) receives a write enable signal. The logic state of the write enable signal determines whether memory (20) writes data into, or reads data from, memory (20). Memory (20) includes row address decoding for selecting a word line (32). During a write cycle, a control signal generated by write control circuit (44) and single-sided delay circuit (45) is provided to row predecoder (42). The old row address is latched, and a new address is prevented from selecting a new word line (32) until the write enable signal changes state to begin a read cycle. Controlling word line selection with the write enable signal ensures that bit line equalization occurs before the beginning of a read cycle.

IPC: H05K1/03
Filed: 1993-07-28
Abstract: The invention concerns base (basic) materials and prepregs from epoxy resin glass fibre fabric for manufacturing circuit boards. The dimensional stabilities of base material and prepreg differs according to type. Attempts to minimise this difference are heat-treatment (temper) processes above the glass transition point and correction factors applied to the production masters (pressing tools). The invention is to improve the dimensional stability of such materials. Using unidirectional weaves in which the ratio of the glass strands in the warp and weft direction, or vice versa, is greater than 70:30 and/or the ratio of the yarn weights in the warp and weft direction, or vice versa, is greater than 1.5:1, and/or have a satin construction brings about a distinct improvement in the dimensional stability at only minimally increased cost.
