Abstract: A supersonic centrifugal compressor comprising an impeller (2), a plurality of vanes (13) radially extending in the impeller to form a plurality of radially extending flow channels therebetween, and a diffuser (3) circumferentially surrounding the impeller and having a circumferential flow channel communicating with the flow channels of the impeller. In the impeller (2), at least one nozzle (18) is provided at the outlet of the flow channel and a contraction (20) is provided at the inlet of the flow channel, so that the flow channel is a low speed flow channel (21). Thus the speed of the fluid is low in the low speed flow channel (21) and high at the outlet of the nozzle (18). Also, in the diffuser (3), backflow preventing and friction reducing projections (33) are provided concentrically in the inner surface of the casing (11). Also, leakage preventing and pressure reducing vanes (37) are provided between the side disc (14,15) of the impeller (2) and the casing (11),   rotatably with the rotatable drive shaft (6). Also, the diffuser (3) comprises a concentric annular contraction (41) and an annular divergent channel (42) on the downstream side thereof. A cross-sectional area of the flow channel at the outlet of the annular divergent channel (42) is greater than that of the flow channel at the largest cross-sectional region (44) on the upstream side of the annular contraction (41), to allow control of the shock wave.

Abstract: A method of manufacturing surface acoustic wave devices includes providing a dielectric substrate (11') with a plurality of channels (12') which open onto a substrate surface region and each of which accommodates a metallic electrode (14), the electrodes being recessed below the substrate surface region by an actual distance which at least equals a desired distance at which the electrodes have a minimum acoustic reflectivity, testing the performance of the device to ascertain at least the acoustic reflectivity of the electrodes, and etching at least the dielectric substrate, when it is ascertained during the testing that the acoustic electrode reflectivity is excessive, at least at the substrate surface region to a predetermined etching depth. The use of this method results in a device having reduced post-etching acoustic electrode reflectivity as a result of the thus obtained reduction in the difference between the actual and desired distances.

Filed: 1990-03-13
Abstract: This invention relates to semiconductor memories and includes a sense amplifier architecture in which sensed data bit lines (e.g. BL2, BL2′) are electrically isolated and shielded from their immediately adjacent active neighbors by utilization of non-selected bit lines (e.g. BL1, BL1′ and/or BL3, BL3′) as an AC ground bus. In its simplest embodiment, shielded bit line (SBL) architecture includes two pairs of opposed bit lines (BL1, BL2; BL1′, BL2′)associated with a common sense amplifier (10). One of each of the bit line pairs is multiplexed into the sense amplifier and the other unselected bit line pair is clamped to AC ground to shield the selected bit line pair from all dynamic line-to-line coupling.

Abstract: A relief image scanner scans successive linear areas on an information-carrying medium such as a plastic card, illuminating each area from two different directions. The reflected light is converted to first gray-level data when the illumination is from one direction, and to second gray-­level data when the illumination is from the other direction. The second gray-level data are subtracted from the first gray-level data; then the difference, and its additive inverse, are compared with a threshold to detect edges of relief patterns on the card, and pairs of edges are connected to create an accurate, distortion-free image of the relief. Additional facilities may be provided to extract edge skeletons before joining the edges, and to capture printed information by binarizing the gray-level data.

IPC: H01H13/18
Filed: 1990-07-26
Abstract: In door switches for vehicles, the operating movement in general corresponds directly to the switching movement, that is to say a large operating movement also results in a large switching movement. This often results in space problems. In addition, a long switching movement also exacerbates reliable sealing of the switches and often necessitates a number of switch variants as a function of the size of the vehicle door gap. These problems in such a switch are avoided in that a switching lever (3) for operating the switching pin (5) on the switch housing (2) or switch flange (11) is supported such that it can pivot about a pivoting axis (12) arranged at right angles to the longitudinal axis of the switching pin (5), and offset laterally therefrom, and has a switching cam (4) resting on the head of the switching pin (5), the switching pin (5) being sealed on the operating side of the switch with respect to the switch housing (2) by means of a diaphragm seal (10) which is self-bracing both on the switch housing (2) and on the switching pin (5). <IMAGE>

Abstract: A communications system such as a digital cordless telephone system comprises primary (or base) stations (PS) and secondary stations (SS), the primary stations over a local area being coupled to a system controller (14 or 15) which interfaces with the PSTN. A TDMA method is used for forward and reverse transmissions between a primary and a secondary station. For digitised speech transmission normally one duplex voice channel formed by one forward time slot (or physical channel) and one reverse time slot (or physical channel) in each frame is allocated for the transaction. For fast data rates it is desirable that additional duplex voice channels be made available quickly for the transmission of a fast data message after which the additional duplex voice channels can be relinquished. In order to facilitate the rapid setting-up of a data transaction, a map store in each data secondary station lists the usage and quality of all the duplex voice channels and the secondary station, when ready to transmit data, immediately uses additional duplex voice channels from those listed, thus avoiding the necessity of scanning all the duplex voice channels before deciding on which additional duplex voice channels to attempt to transmit in.

Abstract: In a digital PLMN network, the short message service of the network can be used for reporting a break-in into a vehicle and for monitoring the movements of the vehicle. An excitation signal arriving at the telephone, for example from a sensor at the driving wheel lock, causes the telephone to form and transmit a short message which includes the clock time, the identification data of a support station, the address of the short message terminal which is to receive the message, and possibly the identification data of the vehicle. The location of the vehicle can be determined from the support station identification data, which support stations transmit as system parameters.

Abstract: A Josephson junction apparatus comprises a polymeric film (1) having flexibility, and a Josephson junction circuit (4) formed on the polymeric film (1). The Josephson junction circuit (4) includes a Josephson junction device (2) and a wiring (5) for connecting to the Josephson junction device (2). Namely, the Josephson junction apparatus has flexibility, and thus the Josephson junction apparatus can be placed not only on a flat surface but also it can be placed on a curved surface in practice. Furthermore, in the Josephson junction apparatus, when a functional polymeric film (11) is used as a substrate of a Josephson junction of the Josephson junction device (2), a protective film is previously formed over the functional polymeric film (11), so that a wetting of the functional polymeric film (11), which is caused by water or organic solvents being used repeatedly during the manufacturing process, can be prevented and a dimensional stability of the film can be increased. Therefore, a minute Josephson junction can be formed onto the polymeric film (11) without causing a dimentional discrepancy in pattern, and a reliability thereof can be increased.

Abstract: The operating latitude of the tri-level xerographic process is improved by replacing the standard DC bias that is applied to one or both of the developer housings (32, 34) in conventional tri-level imaging with a chopped DC (CDC) developer bias (41, 43). Chopped DC biasing is the alternate application of two discrete bias voltages to a developer strucrute in a periodic fashion at a given frequency, with the period of each cycle divided up between the two bias levels at a duty cycle of from 5-10% or 90-95% depending upon which of the two developer structures is being biased. In the case of the DAD developer structure (32) the duty cycle of the higher of the two biases is 5-10% and in the case of a CAD developer structure (34) the duty cycle of the higher of the two biases is 90-95%. The apparatus can be switched to operate in a black monochrome mode, in which only the black developer structure (34) is biased using a standard momchrome bias (4-5).

Abstract: Method and apparatus are disclosed for a programmable multiplexer for converting each of one or more input data signals, with individual data rates, into a second higher data rate signal by mapping contiguously arbitrarily assigned Capacity Time Slots (CTSs) in a capacity domain frame to Time Slots in a Time Domain frame (TDTSs) so the TDTSs for each input signal are substantially uniformly spread throughout the TD frame. The programmable multiplexer receives separate input data rate signals which are clock synchronized to the multiplexer clock from separate synchronizers, and maps the capacity domain of the input signals to the time domain frame format using a 2-step or 3-step digit reverse technique. Both techniques decompose the capacity domain address into predetermined digits from predetermined number bases and then combine the digits to perform a similar computation using the number bases in reverse order. The 3-step technique uses an intermediate step of translating the initially determined values for each the predetermined digits using a bit reversal technique.
