    摘要: Bimetallic plate is produced by providing a substrate of a first metal and, with the preheated substrate positioned in a mold cavity with a major surface of the substrate facing upwardly and to fill a portion of the depth of the cavity, a second metal is cast against that surface to form a cladding component and, with the substrate, to form the bimetallic plate. Prior to the cladding being cast, the major surface is rendered substantially oxide-free and is protected against oxidation. The cladding is cast by a melt, of a composition required for it, being poured at a superheated temperature whereby, with the preheating of the substrate, an overall heat energy balance is achieved between the substrate and the cladding. The heat energy balance causes a diffusion bond to be achieved between the major surface of the substrate and the cladding, and attainment of the energy balance is facilitated by causing the melt to enter the mold cavity through a series of gates which provide communication between at least one runner and the mold cavity. The series of gates is disposed laterally with respect to flow of the melt therethrough whereby the melt forms a laterally extending melt front. Attainment of the heat energy balance is further facilitated by causing the melt front to advance away from the gates, over the substrate surface, at a rate which is substantially uniform across the lateral extent of the front.

    摘要: Creating genetic devices for use in micro-organisms or other biological systems is described. In an embodiment a computer system receives at a program editor, input specifying a plurality of part designs, at least some of which comprise part properties expressed as logical variables; and the input also specifies constraints on the logical variables. For example, the input is a computer program which specifies constraints on the logical variables which, for example, relate to properties of the DNA sequences such as reactions and biological behaviors. In an example, a compiler resolves the constraints using a database of genetic parts in order to generate candidate parts for the proposed genetic device. In examples the sequences of genetic parts are translated into reactions and simulated using an automated simulator and/or implemented in a living cell or other biological system. In embodiments the compiler also uses a database of reactions.

    摘要: An effective sensor for indicating exposure to a toxic gas includes a non-conductive, inert substrate such as glass or polyethylene, a two-dimensional film of nanoparticles of a conductive metal such as silver or copper on the substrate and an electrode connected to each end of the film. When an electrical current passes through the film and the sensor is exposed to a toxic gas, changes in the electrical resistance of the film provides an indication of the presence of the toxic gas.

    摘要: Techniques for performing wafer-level burn-in and test of semiconductor devices include a test substrate having active electronic components such as ASICs mounted to an interconnection substrate or incorporated therein, metallic spring contact elements effecting interconnections between the ASICs and a plurality of devices-under-test (DUTs) on a wafer-under-test (WUT), all disposed in a vacuum vessel so that the ASICs can be operated at temperatures independent from and significantly lower than the burn-in temperature of the DUTs. The spring contact elements may be mounted to either the DUTs or to the ASICs, and may fan out to relax tolerance constraints on aligning and interconnecting the ASICs and the DUTs. Physical alignment techniques are also described.

    摘要: One embodiment of the present invention concerns an integrated circuit that includes bond pads and special contact pads or points. The bond pads are for interfacing the integrated circuit as a whole with an external circuit, and are to be bonded to a package or circuit board. The bond pads are disposed on the die in a predetermined alignment such as a peripheral, grid, or lead-on-center alignment. The special contact pads are used to provide external test patterns to internal circuits and/or to externally monitor results from testing the internal circuits. The special contact pads may be advantageously located on the integrated circuit with a high degree of positional freedom. For one embodiment, the special contact pads may be disposed on the die at a location that is not in the same alignment as the bond pads. The special contact pads may be smaller than the bond pads so as not to increase the die size due to the special contact pads. The special contact points may also be used to externally program internal circuits (e.g., nonvolatile circuits) at the die or package level. The special contact points may also be used to select redundant circuits for faulty circuits.

    摘要: A method and system for allocating distributed resources connected to a computer network to application programs running on computers attached to the communications network. The distributed resource allocator system comprises a number of identical processes running on one or more computers attached to the communications network. Application programs request allocation of resources from a local distributed resource allocator system process running using a resource allocator applications programming interface. Application programs request allocation of resource from a remote distributed resource allocator system process via a resource allocator access protocol. The distributed resource allocator system is fault-tolerant and provides contention control and load balancing. The resource allocator system also manages information about the capacities and capabilities of resources connected to the communications network. Application programs can thus be easily written to make use of distributed resources connected to a communications network without having to manage global network information and without needing complex contention control and load balancing subroutines.
