Abstract: ABSTRACT OF THE DISCLOSURE            An  assembly  of waveguides  and coupling  apertures located  within  walls  separating  the  waveguides  is formed within a planar configuration.   The coupling apertures are arranged either singly or in pairs, with one  coupling  aperture  behind  the  other  coupling aperture, to provide for a division of power between waveguides and to provide for a crossing over of power from one waveguide to another waveguide. The waveguide assembly is reciprocal in operation so that the single coupling apertures may be employed for a distribution as well as for a combination of electromagnetic waves. Phase  shifters  may  also  be  included  to  provide  a desired phase relationship among waves outputted by various ones of the waveguides.  The waveguides,  the walls separating the waveguides, the coupling apertures and the phase shifters may all be  fabricated  in a parallel  array  within  a common  metallic  plate  by automated milling machines for facile,  accurate,  and reproducible manufacture of the waveguide assembly. The waveguide assembly including the matrix of passages for electromagnetic waves is readily structured to serve as a Butler matrix.

Abstract: POLYSILICON THIN FILM PROCESS AND PRODUCT                 ABSTRACT OF THE DISCLOSURE   Polycrystalline silicon is deposited in a film onto the surface of a substrate which has been carefully prepared to eliminate any defects or contaminants which could nucleate crystal growth on the substrate.  The deposition is carried out by low pressure decomposition of silane at substantially 580°C to cause a film of fine grained crystals of polysilicon to be formed having grain sizes averaging less than about 300 Angstroms after annealing.  Such a film is very uniform and smooth, having a surface roughness less than about 100 Angstroms RMS. Annealing of the film and substrate at a low temperature results in a compressive strain in the field that decreases over the annealing time, annealing at high temperatures (e.g., over 1050°C) yields substantially zero strain in the film, and annealing at intermediate temperatures (e.g., 650°C to 950°C) yields tensile strain at varying strain levels depending on the annealing temperature and time.  Further processing of the polysilicon films and the substrate can yield isolated diaphragms of the polysilicon film which are supported only at edges by the substrate and which have substantial lateral dimensions, e.g., 1 cm by 1 cm.  Such that structures can be used as pressure sensor diaphragms, X-ray masks, and optical filters, and can be provided with holes of varying sizes, shape and number, which can serve as X-ray mask patterns.  The diaphragms can be provided with numerous holes of uniform size and spacing which allows the diaphragms to be used as filters in ultrafiltration applications.

Title: Computer look-ahead instruction issue control

IPC: G06F9/38

Granted: 1993-08-03
Abstract: ABSTRACT   A system for scheduling instruction issuance in a vector register computer achieves increased efficiency of operation by performing pre-issuance checks to determine if resources requested by the instruction will be available when the instruction issues. A decoding apparatus first determines particular resources requested by the instruction, which includes apparatus for decoding vector register requests, functional unit requests, and address and scalar register path requests. Following decoding, a conflict resolution apparatus checks resource reservation flags to determine if the requested resources will be available when the instruction issues. If any requested resources will be busy, the system issues a primary conflict signal. At the scheduled instruction issuance time, the system again checks the resource reservation flags in response to the primary conflict signal. If the requested resources are still busy, the system generates a secondary conflict signal for as long as the requested resources remain busy. Finally, when the instruction issues, the system sets the resource reservation flags to reserve the requested resources for the instruction.

Abstract: A press for converting work pieces into finished parts has an elongated bolster mounted on a press bed. The bolster supports columns on which a ram is slidable. The bolster also supports the lower die shoe of the press tooling.          A conveyor transfer system mounted on the bolster carries work pieces into and out of the area of the tooling. The bolster is a unitary piece which integrates support of the die shoe, columns and conveyor to assure proper cooperation and alignment among them. A pivotable carrier mounts a feed mechanism for feeding a stock strip into the tooling. Power to the feed mechanism supplied through a shaft which is coaxial with the hinge line of the carrier, so that the carrier can be swung away from the tooling for service access without requiring disconnection of the power supply. A traveling vacuum box on the lower die shoe supports the conveyor for vertical as well as longitudinal motion, and retains the work pieces on the conveyor.

Abstract: The present invention relates to a method for producing a continuous web of material (36) on an endless belt (24). Fibres suspended in a carrier gas are transported from a transport conduit (12) through a transition part (38) of zig-zag configuration, having cross-section which tapers or narrows in the flow direction . Arranged at the outlet aperture of the transition part is a coarse-particle separator means (22) which incorporates a curved, convex surface (60), an accept outlet (48), and a reject outlet (54). The carrier gas is deflected around the convex surface, as a result of the ensuing Coanda-effect, and transports fine fibres to the accept outlet, while coarse particles, due to their greater kinetic energy, pass in a straighter path to the reject outlet (54). The accept outlet leads directly to a distribution chamber (52) which is located above the endless belt (24), and opposite which there is provided a suction box (32) for extraction of the carrier gas.

Abstract: The invention relates to a dipole curtain antenna for radiating short-waves, in which the dipoles are arranged in columns and rows. Dipole curtain antennas are known. They consist of horizontally polarised dipoles which are arranged in a vertical plane, to be precise in columns and rows. They are used for producing short-wave radio links with the aid of the ionosphere. The requirement exists to supply different destination areas in successive periods of time with one antenna, or to reach the same destination area when the ionosphere is at different heights. This necessitates a change to the vertical polar diagram and, since the number of dipoles determines the type of directivity of the polar diagram, it is intended to create a dipole curtain antenna (e.g. a 4/6) with a high number of dipoles in which it is intended that different operating modes should be possible, e.g. 2/2, 2/4 or 4/4, without the polar diagram having been distorted. It is also intended to be possible to change the polarity of some dipoles. According to the invention, the dipole curtain is constructed of individual dipole modules, each dipole module consisting of two horizontal and/or two vertical dipoles and the vertical interval in each case between adjacent dipoles being less than  lambda /2 inside the module and greater than  lambda /2 outside the module, and the horizontal interval from dipole centre to dipole centre (centre interval) in each case between adjacent dipoles being equal to lambda /2 inside the module and greater than  lambda /2 outside the module, the vertical interval between adjacent dipoles preferably being approximately 0.4 lambda  inside the module and approximately 0.6 lambda  outside the module, and the centre interval between adjacent dipoles outside the module being 1.2 lambda .
