Abstract: The invention relates to variable-threshold semiconductor memory elements, and to memory arrays of such elements. The elements 117 may be arranged in an array 115 of rows 118 and columns 119. Each element comprises source and drain electrodes 130, fixed threshold access gate regions 38 and 39 respectively connected to row conductor 124 and column conductors 122 and a variable-threshold memory gate 31 connected to a row conductor 44. The conductors 122 and 124 permit adjoining elements to be written at different times, so that adjacent columns 119 need not be isolated from each other, and a common source-drain line 130 can serve as the drain electrode of one element and the source electrode of the next.

Title: Portable gas-powered tool with linear motor
Inventor: NIKOLICH MILOVAN
IPC: B25F/
Filed: 1982-01-21
Abstract: An efficient, portable, easy to operate tool employing a linear motor (130) is disclosed that is powered by the gases produced from the internal combustion of a fuel and air mixture. A supply of liquified gas stored under pressure in a cylinder (104) provides the source of power. The linear motor (130) is slidably mounted within a cylinder (104) to move reciprocally downwardly and upwardly through a driving and return stroke. A combustion chamber (120) is formed at the upper end of the cylinder (104). A spark plug (164) powered by a piezo-electric firing device (182) is located within the combustion chamber (30). The combustion chamber (120) features a turbulence generator, such as a fan (122), driven by an electric motor (122) which is continuously in operation when the tool is in use. A main valve mechanism (136) actuated by a set of lifting rods (144A, 144B) that are moved upwardly and downwardly when the tool is moved towards and away from the workpiece, is used to control the opening and closing of the combustion chamber (120) and to control the flow of fresh airthrough the combustion chamber (120). When the combustion chamber (120) is isolated from the atmosphere and the fuel and air are thoroughly mixed, the spark plug (164) is fired to explode the fuel and air mixture and force the linear motor (130) through its driving stroke. The linear motor (130) is returned to its driving position by a spring (148) or air acting against the underside of the linear motor (130). The unique use of the electric fan (122) improves the overall operational efficiency of the tool and the utilization of the liquified combustible gas.

Abstract: A bar-code label has a combination of a plurality of narrower slots and a plurality of wider slots encoded to represent specific binary data containing information and/or instructions. The slotted bar-code is encoded on a rigid label member, such as a metal sheet. A bar-code encoding device used to encode the slotted bar-code has a pair of punches, one of which is adapted to form the narrower slots and the other of which is adapted to form the wider slots. Both of the punches are operated simultaneously whenever one of the narrower orwider slots is formed. The blank label is fed past one of the punches to form all of the narrower or wider slots before forming the rest of the wider or narrower slots with the other punch. The encoded label thus formed is suitable for use in painting or coating processes which would obscure a conventionally printed bar-code label.

Abstract: A document indexing apparatus and method is disclosed that facilitates access to sequentially stored documents in a diskette (11) of a word processing system. The invention uses random access memory (12) to build a page index (36) when the sequential data stream is first processed. The page index (36) is then available so that subsequent access to previously processed pages is faster than conventional sequential access. The page index (36) has associated with it an offset index (36) having pointers to the actual entries in the page index (36). If the page index (36) proves too small to store an index entry for every single page of a document, the offset index (34) is reorganized to point to every other entry in the page index (36). Reorganization effectively doubles the span of pages covered by the page index (36) and may be repeated a plurality of times to allow a sequentially stored document of arbitrary length to be indexed by a fixed length page index (36).
