Abstract: Thin semiconductor wafers and components manufactured therefrom, for instance solar cells of crystalline silicon, are subject to an increased breakage risk because of the brittle nature of the material and require a minimum thickness for the wafer in order to assure reliable handling. For improving the handling, a semiconductor wafer is provided surface-wide with a mechanical protective layer and this semiconductor wafer is subsequently subjected to a shaping treatment.

Abstract: A terminal device, such as a computer, workstation or smart phone, incorporates a memory structure which simplifies and facilitates communications between a host computer and the terminal device. The host computer and the terminal device exchange application interface information via a communications protocol in which the host computer associates different types of objects with respective identifiers and then transmits an object type and its associated identifier to the terminal device. The terminal device, in turn, displays the object in a form determined solely by the terminal device but in accordance with respective predefined policies determined by the memory structure. If a user manipulates a displayed object type, then data representative of such manipulation is generated and transmitted with the associated object identifier to the host processor.

Abstract: A modular solid-state mass data storage device providing high-density, high capacity storage of numerous full-length movies for video server applications. The mass data storage device employs a modular pipeline architecture in which a distributed array of controller/memory modules is arranged in parallel controller/memory channels on one or more controller/memory cards. The modular pipeline architecture, in which each controller/memory channel has multiple controller/memory modules connected in a serial chain by address, data and control buses, allows the number of controller/memory modules in each channel and the number of controller/memory channels to be selected to accommodate a desired storage size and transfer rate, without an undesirably high latency time. An asynchronous transfer mode (ATM) switch allows multiple viewers to access the movies stored in the mass data storage device with independent video cassette recorder (VCR)-like control of the movie being watched.

Abstract: A superconductive-magnet electrical circuit includes a superconductive-coil assemblage having first, second, third, and fourth coil portions sequentially coupled together in series. A bipolar current-bypass electrical-circuit element (such as a pair of diodes opposingly coupled together in parallel) has:an impedance less than generally one-thousandth that of the coil portions; a first terminal coupled in parallel with the first and second coil portions; and a second terminal coupled in parallel with the third and fourth coil portions. A localized quench in one coil portion is quickly shared with the other coil portions to reduce damage from the quench. A resistor has a lead coupled in parallel with the second and third coil portions to limit quench voltages.

Abstract: An initiator, for use in a gas generator, includes an enclosed volume in communication with apertures for introducing liquid propellant and pre-pressurization gas into a propellant ignition chamber, and an aperture for introducing combusted gasses into a gas generator. A mechanism for controlling when the gases are allowed to enter the gas generator, and a heater/electrode to initiate combustion of the liquid propellant, also communicate with the enclosed volume. The propellant and the pre-pressurization gas may be introduced together or through separate ports. The heater/electrode thermally decomposes and vaporizes the propellant causing pressurization of the ignition chamber until a critical value is reached and the propellant ignites and burns. The burning propellant increases the chamber pressure beyond a predetermined value thereby opening the controlling mechanism and allowing the combusted gases to be introduced into the gas generator combustion chamber.

Abstract: A programmable data acquisition system including a plurality of input signal channels for receiving a respective input signal during a normal mode of operation is provided. Individual test circuits are used for selecting respective ones of the plurality of channels to receive predetermined reference signals during a test mode of operation while uninterruptedly providing the normal mode of operation in any remaining unselected channels in the data acquisition system. An analog-to-digital (A/D) converter system allows for supplying quantized electrical signals at a predetermined rate. The A/D converter is responsive to any signals carried in the plurality of signal channels as selected by the individual test circuits. A control unit allows for supplying respective control signals to the test circuits and to the converter system.

Abstract: A fault recovery system and method that deterministically reconstructs the instruction stream of a multiple execution stage ("pipelined") processor. A log ("queue") is provided for each critical data item to record the instructions, operations and effects as processing proceeds. Also, rather than merely freezing the execution of a specific stage upon occurrence of a fault, all stages are stopped so that each stage does not overwrite log information that is needed to reconstruct the instruction flow immediately preceding the invocation of any fault recovery operation. The fault recovery operation may then serially reconstruct the instruction flow, advantageously starting with the instruction where the fault occurred, working to reconstruct from that instruction to the last instruction that was executing before the fault recovery operation began.

Abstract: A method for joining carbon-carbon composites to metals by brazing. Conventional brazing of recently developed carbon-bonded carbon fiber (CBCF) material to a metal substrate is limited by the tendency of the braze alloy to "wick" into the CBCF composite rather than to form a strong bond. The surface of the CBCF composite that is to be bonded is first sealed with a fairly dense carbonaceous layer achieved by any of several methods. The sealed surface is then brazed to the metal substrate by vacuum brazing with a Ti-Cu-Be alloy.

Abstract: Tris-aryl-s-triazines of formula V ##STR1## which contain from one one to three resorcinol derived moieties with at least one of said moieties substituted in the 5-position with a group such as, for example, alkyl or phenylalkyl have UV spectra which are red-shifted to the near UV range and provide excellent stabilization to polymeric substrates against the deleterious effects of actinic light.

Abstract: A binder composition of a phenolic novolac resin and a (lower) alkoxylated triazine-formaldehyde resin curing agent is disclosed. The triazine resins have sufficient carbon atoms in the alkoxy groups so as to provide a curing agent having a water solubility of less than 15%. The binder cures at high temperatures so as to provide improved flow and prolonged workability to the composition. The compositions are useful in refractory applications having a need for high temperature curing agents such as for maintenance and repair within refractory vessels by gunning/spraying, manufacture of electrodes by the Soderberg method, and for use in blast furnace tap holes.

Abstract: A radio communication system (100) includes a system control display interface (201) to provide operational control. A radio system control panel (261) is automatically arranged in a relative pattern with respect to other control panels (260) on the display interface (201), such that when operating in a mode that expands beyond predefined borders, the control panel (261) covers a non-critical display area (282) defined on another control panel (262) formed on the display interface (201), but does not cover a critical display area (282) defined on that control panel (262).

By using the disclosed system and assemblage, the geometric configuration and the dimensions of the microtexturized surfaces can be pre-determined to impart a customized design texture on the implant or substrate surface thereby optimizing implant acceptance by and durability in the host tissue and the in vitro promotion of the growth and development of various types of cell tissue on substrates.

Abstract: A method of making a microelectronic circuit and the connection pattern therefor including the steps of providing a substrate (3), preferably silicon and preferably including a layer of nickel (38) under a layer of gold (36) thereon. Regions are formed on the substrate for connection of electrical components to the substrate using a first metallurgy, preferably gold and a pattern of bumps (5, 7) is formed of a second metallurgy different from the first metallurgy, preferably lead/tin solder. An interconnection pattern is formed on the substrate contacting at least one bump and at least one pad. The pattern of solder bumps is formed by providing a coupon (31) and patterning the bumps on the coupon and applied to the substrate while attached to the coupon, then heated to cause flow of the bumps onto the substrate. The coupon is then removed from the bumps with the bumps remaining on the substrate.

Abstract: A portable slitter for selectively roll slitting rib forming or perforating sheet metal workpieces and having a beam-type frame, a pair of spaced thin walled and light weight rotary torque tube roll shafts mounted in the frame and supporting the work rolls, and a plurality of pairs of opposed stabilizing support blocks disposed between the shafts and the associated frame beams and providing further strength to the shafts by functioning as intermediate span shaft journal supports carrying the roll work loads imposed on shafts directly into the frame beams. The bearing members can be readily removed and adjusted longitudinally of the shafts without taking the frame apart. The slitter can be readily manually transported to the work site because it has a high strength-to-weight ratio and is light in overall weight. The slitter has substantial operational strength and improved work roll registry and alignment under continuous and/or adverse on-site operating conditions.
