Patent EP-0309428-A2 (EP)
Inventor: PENCE JERRY W
IPC: G06F13/18
Filed: 1988-09-12
Abstract: A multiported resource(ll), such as a tape or disk media library with ports (13) being drives or record players-­recorders, is connected to a plurality of host processors (10). The host processors access the resource using short duration accesses for on-going data processing operations. Such short duration accesses usually are for one or a few data sets and take a relatively short time to complete. The host processor also access the resource for data volume (many, many data sets) dumping, volume backup, volume recovery (return volume contents to one or more host pro­cessors), volume migration (transfer contents of one volume to another volume) and the like. Such extensive data transfers require extended times to complete, such as one or more orders of magnitude longer than the short accesses. Access priorities are setup for ensuring efficient usage of the host processors and the multiport resources.

Abstract: A semiconductor device for operation under cryogenic conditions has a structure similar to that of conventional bipolar transistors, but a different impurity doping profile. The impurity concentration for a "base" layer (14) of the device is controlled to be larger than 5 x 10¹⁸ cm⁻³, preferably 1 x 10¹⁹ cm⁻³ or more, and the impurity concentration for an "emitter" layer (15) is controlled to be in a limited range less than the above value, but greater than 1 x 10¹⁷ cm⁻³. The above doping profile enables the device to operate satisfactorily from temperatures below about minus 100 decrees centigrade down to liquid nitrogen temperatures and further makes it suitable for a high-speed operation.

Abstract: When rewinding from unwinding bobbins to cross-wound bobbins on winding devices of an automatic winder, difficulties may arise when pulling off the thread if there are only a few layers of yarn on the tube of the unwinding bobbin, such difficulties being manifested as thread entanglements and, as a consequence of these, as stress breakages. …<??>To overcome these difficulties, a method for detecting unwinding bobbins is presented, the unwinding properties of which do not correspond to a predeterminable quality. For this purpose, the winding speed is measured and a thread breakage in relation to the winding speed is used for detecting the quality of the unwinding bobbin and, if it falls below the given quality, the corresponding unwinding bobbin is rejected and the winding operation is continued using a new unwinding bobbin. …<??>The device according to the invention for carrying out the method provides for a signal processing apparatus (11), in which the winding speed signal up to a predeterminable winding speed and the thread breakage signal can be input. The signal processing apparatus (11) then produces a signal and transmits it if the signal of the winding speed below the predeterminable winding signal and the thread breakage signal are present at the same time. …<IMAGE>…

Abstract: There is provided a method for impregnating antibodies or antigens into a matrix. The method comprises the steps of passing a solution of antibodies or antigens through a nozzle, so as to form free liquid droplets containing the antibodies or antigens, and directing the liquid droplets through the air toward a matrix whereby the antibodies or antigens are deposited on the matrix according to a predetermined macroscopic pattern. Suitably this is achieved by the droplets being electrostatically charged so that they may be deflected into the predetermined macroscopic pattern on the matrix by means of an electrostatic field.

Abstract: In order to sense the temperature of an integrated circuit chip, a semiconductor junction device (D1) integrated on the chip is used to generate a first signal (V₁) having a known variation with temperature. A second signal (V₂) is generated by passing a PTAT current (I₂) through a resistor (R1) so that the second signal (V₂) has a known variation with temperature which is opposite in sign to that of the first signal (V₁). The two signals are compared (42) to generate an output signal (0T) which is dependent on whether the temperature of the chip is below or above a predetermined threshold temperature. The current (I₁) through the junction device (D1) is also PTAT, enabling a more accurate definition of the threshold temperature in terms of integrated circuit parameters.

Abstract: An illumination system for an LCD projection display system to increase the brightness of the system. The system includes a polarizing beam splitter (26) which splits a beam of light (24) from a light source (20) into two orthogonally polarized beams (28,30). The beam of the desired polarization direction (28) is directed through a first face (A) of a prism (10) so that it reflects off of a second face (B) of the prism and exists through a third face (C) . The other beam (30) of the non-desired polarization direction is passed through a device (36) for rotating its polarization 90° and towards the underside of the second face (B) of the prism (10) at an angle such that it is refracted into the prism. Both beams (28,30) then exit the prism (10) through its third face (C) , have the same polarization direction, and are only slightly divergent. The recombined beam may be thereafter directed towards the light modulation system. The illumination system minimizes the number of air-glass interfaces and the number of reflecting surfaces.

Abstract: A short range, high resolution, radar system of particular use in training radar operators. The system transmits very short pulses of a radio-frequency (RF) signal at a very high pulse repetition frequency, PRF o . A signal pre-processor samples a received baseband radar signal and generates a time-expanded signal which is a replica of the real received radar signal, but with a much lower nominal pulse repetition frequency, PRF n . The signal pre-processor includes a sampling circuit which receives the baseband signal, and a timing circuit which controls the sampling circuit. The timing circuit operates by causing samples of the baseband signal to be taken at progressively later portions of subsequent pulses. While the radar system is particularly useful in demonstrating radar principles in a classroom setting, it has other applications.

Abstract: An improved apparatus and method for regulating transmembrane ion movement through a biochemical membrane. The apparatus includes a magnetic field generator and a magnetic field detector for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through the membrane. The field detector samples the magnetic flux density along the predetermined access and provides a signal to a microprocessor which determines the average value of the flux density. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target membrane is subjected. By maintaining these precise predetermined ratios of frequency to average magnetic flux density, ion transport is controlled.

Abstract: A compliant electrical connector pin for press-fit connection to a plated hole in a circuit board is disclosed. A compliant section (14) is provided on the pin (12,14) to frictionally engage the hole walls, thereby retaining the pin within the hole. The compliant section includes two V-shaped throughs (40,42) having flat bottom faces (58,58). These faces define a web (68) which compresses when the compliant section is pressed into the hole. Barrier walls (60,62,64,66) in the bottom of each trough normal to the flat bottom face guide the compression of the web and prevent the web from splitting or shearing. The sides of the trough define two flanges (70,72), the exterior of which contact the hole in the circuit board. The outer corners (84,86,88,90) of the flanges are angled to match more closely the circular shape of the hole, thereby reducing hole damage from sharp corners on the compliant section and enabling the pin to fit smaller diameter holes.
