Title: Multi-level circuit card structure
Inventor: BREGMAN MARK FIELDING
IPC: H05K3/32
Filed: 1990-03-21
Abstract: Structure for mounting electronic devices thereon. The structure is fabricated from a plurality of substrates (4, 6, 8, 10) each having a thermally and/or electric­ally conductive core (12) surrounded by a dielectric material (13). The substrates can be adherently placed together with the electrically conductive cores provid­ing ground and power planes or the substrates can be mounted together with connectors (42) electrically interconnecting adjacent substrates and spacing the ad­jacent substrates apart providing a space through which a fluid can flow to extract heat generated by the electronic devices mounted thereon. The conductive cores provide both power and ground planes to the structure and a means for thermally dissipating the generated heat.

Abstract: This apparatus and method distinguish component leads which have been defectively inserted through holes in printed circuit boards from properly inserted ones on the basis of an imaging pattern. The pattern is produced by projecting different colors of light onto the parts of the circuit board where the leads are inserted in such a way that the light illuminates the board at different angles of incidence. The leads are inspected automatically as to proper insertion on the basis of patterns in polar coordinates generated from the imaging data.

Inventor: STAFAST HERBERT DR
IPC: H01B3/00
Filed: 1991-10-30
Abstract: To improve the coating growth in pulsed deposition processes, in particular by pulsed laser or pseudo-spark ablation, gas pulses (8) are applied to the substrate (5) or the film surface in the form of supersonic molecular beams (or atomic beams) having a duration of 1 mu s to 10 ms. The gas pulses are coordinated with the ablation pulses (2) in time in such a way that, for example, a gas pulse reaches the substrate shortly after the ablated particles. As a result of the pulsed gas supply, the pressure at the substrate may be markedly higher than the maximum possible steady-state background pressure for a short time, thereby appreciably improving its incorporation in the case of a reactive gas. In addition, the steady-state background pressure can be much lower in the case of the process according to the invention than with a steady-state gas supply, as a result of which large-area substrates can be coated. In many systems, the invention makes it possible to reduce the substrate temperature appreciably if pulses of the reactive gas are blown onto the substrate in activated form (as ions and/or radicals). <IMAGE>

Abstract: Apparatus for priming a centrifugal pump (1) comprises a closed circuit connected to the casing of the pump and consisting of a priming pipe (12) connected to a vertical section (10) of an outlet pipe (4) from the pump downstream of a non-return valve (8) in the outlet and to the pump outlet upstream of the non-return valve (8). A valve (13) is provided in the priming pipe (12). A second part of the closed circuit consists of an air displacement pipe (14) which is connected to an upper part of the pump casing (1) and to the upper end of the outlet section (10). A non-return valve (17) is provided in the pipe (14) and a further valve (15) is provided in the pipe (14) adjacent the pump casing. The valves (13, 15) are closed during normal operation of the pump. When the pump is stopped, liquid is retained in the outlet pipe and in the priming pipe (12). The pump can be primed by opening the valves (13, 15). Liquid flows along the pipe (12) and into the pump casing (1) and air displaced from the casing can pass along the air-displacement pipe (14). In this manner the pump can be primed, i.e. filled with liquid, without recourse to secondary priming means.

Abstract: A semiconductor memory device is provided comprising a nonvolatile memory cell through which an LSI and a higher operating speed are achieved. A drain region, and a gate electrode formed on the insulating layer are formed on a semiconductor substrate thereby making up a memory cell without a source region. An energy gap between the conduction and valence bands of a semiconductor section is preset to a value corresponding to a first set voltage difference between the drain and the gate. The energy gap between the valence bands and the semiconductor section at the interface between the semiconductor section and the insulating layer is preset to a value corresponding to a second set voltage difference between the drain and the substrate. Write operations are done by trapping a charge which has jumped the valence band of the insulating layer at a voltage not less than the second set voltage difference. Read operations are done at a voltage not less than the first set voltage but not more than the second set voltage. Erase operations are done by releasing a charge trapped or by implanting a reverse charge.
