Patent EP-0247901-A2 (EP)
Inventor: BERNARDON EDWARD
IPC: B25J15/06
Filed: 1987-06-01
Abstract: An apparatus for controlling the shape of an elongated flexible spline (218) to substantially match a third order polynomial curve extending between first and second end points where the spline extends along a deformable central axis (212). A spline support member (210) extends along the central axis. The spline is pivotably coupled to the support member at a first point along said central axis, and is slidingly coupled to the support member at second, third and fourth points along the central axis. The support member establishes a first predetermined distance (L) along a reference line passing through the interior two of said first, second, third and fourth points. A first spline deflector (230) select­ively deflects one of the exterior two of the first, second, third and fourth points by a distance D L  in a direction perpendicular to the reference line. A second spline deflector (232) selectively deflects the other of the exterior two of the first, second, third and fourth points by a distance D R  in a direction perpendicular to the reference line. A controller controls the first and second spline deflectors so that the central axis of the spline is deformed and the intermediate two points substantially match points of the polynomial curve and so that the exterior two points are offset with respect to the reference line and the spline central axis overlies the first and second end points of the curve.

Abstract: A multinode parallel-processing computer comprises a plurality of interconnected, large capacity nodes (12) each including a reconfigurable pipeline of functional units such as Integer Arithmetic Logic Processors, Floating Point Arithmetic Processors, Special Purpose Processors, etc.. The reconfigurable pipeline of each node (12) is connected to a multiplane memory (28) by a Memory-Alu Switch NETwork (MASNET) (26). The reconfigurable pipeline conveniently includes three basic substructures formed from functional units which have been found to be suffic­ient to perform the bulk of all calculations. The MASNET (26) controls the flow of signals from the memory planes (30) to the reconfigurable pipeline (24) and vice versa. The nodes (12) are connectable together by an internode data router (Hyperspace router) so as to form a hypercube configuration. The capability of the nodes (12) to con­ditionally reconfigure the pipeline (24) at each tick of the clock, without requiring a pipeline flush, permits many powerful algorithms to be implemented directly.

Abstract: A constant current semiconductor device comprises a first semiconductor active layer (22, 23) and a second semiconductor active layer (24, 25) which is of a different material from the first active layer and forms a heterojunction together with the first active layer. An intervalley energy difference ΔE₁ of the first active layer which is a difference in energy between bottoms of L and Γ valleys of the conduction band of the first active layer is different from an intervalley energy difference ΔE₂ of the second active layer which is a difference in energy between bottoms of L and Γ valleys of the conduction band of the second active layer. A current saturating voltage at which a current passing through the semiconductor device is saturated is set so as to be equal to or greater than ΔE₂/e, where  e  is an absolute value of charge of an electron.

IPC: C08G63/685

Abstract: Multidimensional oligomers of the present invention are surprisingly useful for advanced composites because each generally has a use temperature greatly in excess of its curing temperature. The oligomers have essentially no arms, and comprise crosslinking phenylimide end caps condensed directly onto an aromatic hub (preferably, phenyl) through "commodity" polymeric linkages, such as amide, diimide, ether, or ester. For example, p-nadicimido­benzoylchloride can be condensed with triaminobenzene to yield a multidimensional, crosslinking amide oligomer. Short chains of ether/carbonyl aromatic chains can be included, if desired. Methods for making these high-­performance oligomers with ether/carbonyl aromatic chains use an Uhlman ether synthesis followed by a Friedel-Crafts reaction.

Abstract: A switching system is disclosed in which a plurality of incoming highways are multiplexed in time division cells that have arrived are written into a buffer memory (105), the cells thus written are read in an appropriate order, separated in a multiplex way and distributed among a plurality of outgoing highways thereby to perform an exchange operation. An FIFO (First In First Out) buffer (103) stores an empty address of the buffer memory (105). The address in busy state is controlled in a manner corresponding to the outgoing highways. When a cell is written in the buffer memory (105), the empty address is taken out of the data output of the FIFO buffer. When the cell is read of the buffer memory (105) the address already read is returned to the data input of the FIFO buffer by an idle address chain (103-104-105-104-110-103).

Abstract: A control system comprises a liquid crystal display panel; a light source; light detector means; and means for directing light through at least a portion of the liquid crystal display panel to the light detector means. Control means are provided for holding the liquid crystal display in generally opaque condition while preferably sequentially momentarily clarifying segments of the portion, whereby momentary, sequential, transversely spaced light beams are generated between the light source and the light detector means. Timer and logic means are provided for correlating signals received from the light detector means with generated, individual, spaced light beams that create said signals. Accordingly, occlusion of at least one of the individual light beams with an opaque member causes a specific characteristic response by the timer and logic means. In other words, when one of the individual light beams is occluded, the timer and logic means emits a characteristic signal which might activate a relay, send an instruction to a microprocessor, or cause some other action.

Abstract: An apparatus for calculating a filter factor for a digital filter which can be made with a simple construction and in which the time period for calculation can be shortened as compared with conventional techniques. The apparatus comprises an inputting circuit (1) for inputting a desirable frequency property, a division circuit (2) for dividing the inputted frequency property into a plurality of frequency bands, and a calculating circuit for obtaining filter factors for realizing a frequency property of each of the divided frequency bands. The inputting circuit inputs the frequency property with a frequency resolution corresponding to the number of the filter factors. The division circuit performs a correction for a division so that the frequency property becomes zero from a frequency over the high cut-off frequency of a band-pass filter toward the Nyquist frequency of the frequency band corresponding to the transversal filter, the Nyquist frequency being 1/2 of the sampling frequency. The calculating circuit has a transformation unit (3) for performing a Hilbert transformation or a linear phase transformation with respect to the respective frequency properties divided by said division means.

Abstract: This invention applies the linkage connected between the interaxle yokes(16,18) of a truck and a railroad vehicle car body so as to create radially steered alignment of wheelsets(12,14) on circular curves without reference to the truck frame. Forces exchanged between the wheelsets and the car body are essentially longitudinal and no significant lateral forces are created on the truck frame or car body from the steering action. The steering linkage (34,40,46) utilizes the longitudinal component of relative motion of a point on the car body with reference to the vehicle truck to cause relative pivotal movement of the interaxle yokes thereby guiding the wheelsets to a radial alignment. Radial alignment is achieved by suitable proportioning of the links of the mechanism.
