Abstract: A valve configured for use with a fuel cell in both a disengaged position, in which the valve has not established fluid communication with the fuel cell, and an engaged position, in which the valve has established fluid communication with the fuel cell. The valve includes a body having a first formation for maintaining the disengaged position, and a second formation for maintaining the engaged position.

Abstract: An improved fastener driving tool is provided that is especially adapted to the application of fasteners in trim applications, such as the fastening of wood trim and decorative pieces. The preferred embodiment is a combustion tool, and includes an incrementally adjustable fastener driving depth setting mechanism. The incremental control permits an operator to select from a number of discrete depth settings over a limited range. The preferred tool also includes a distance amplifying fastener lockout. The lockout amplifies a fastener follower movement permitting the blocking of movement of a linkage necessary to tool operation in response to the movement associated with an individual small fastener being dispensed. A trigger and handle of the preferred tool are proximate to the driver blade axis, and the trigger is disposed within an imaginary extension of a fuel canister held within the tool housing.

Abstract: The method includes forming in one surface of an N+ silicon wafer a matrix of uniformly deep V-shaped grooves, growing one SiO.sub.2 over the one surface and the walls of the grooves, forming over the opposite wafer surface a thick self-supporting polycrystalline layer, progressively removing portions of the original silicon wafer until the bottoms of the grooves are detected to leave separate patches of the original N+ silicon wafer material and then growing a thin (e.g. 6 microns) P-doped layer of epitaxial silicon on the exposed N+ silicon layer patch portions now isolated and defined by the grooves. A figure-eight pattern of trenches is formed in each silicon island completely through the P epitaxial layer and each of the underlying N+ buried patches but stopped at the SiO.sub.2 layer. An N+ plug is formed through the epitaxial layer to each N+ patch.

Abstract: A simple silicon integrated circuit consists of two identical Schottky diodes formed in epitaxial pockets that are defined by P-N junction isolation walls. Metallization is provided to connect the diodes back-to-back in parallel and to provide terminal pads at the two nodes of the parallel circuit. Another metal film makes contact with the isolation wall and has an enlarged termination pad portion. This component may be connected across the input of an A/D converter to limit input signals to a small value.
