Title: Memory cells for a programmable read-only memory
IPC: G11C17/06
Filed: 1981-12-24
Abstract: A semiconductor memory cell for a programmable read-only memory includes a polysilicon layer (14) formed with laterally-spaced surface regions (22, 36, 18) the outer two of which differ in impurity concentration and which form two back-to- back series diodes (34, 36) functioning as a programmable diode (34) and an isolating diode (36). Because of the different impurity concentration, the diodes (34, 36) have different reverse-bias breakdown voltages. The programmable diode (34) has the lower reverse- bias breakdown voltage. The high reverse-bias breakdown voltage of the isolating diode (36) has the effect of blocking the parasitic current drain on the programming current. Many different configurations of laterally-spaced regions are described. <IMAGE>

Title: Release mechanism for parachute loads
Inventor: OASTLER GILBERT EDWARD
IPC: B64D17/38
Filed: 1982-05-04
Abstract: A mechanism for releasing a load from a parachute on landing is disclosed. A sleeve (10) mounted in a body member (2), attached to a parachute, is urged by coil spring (13) towards an extreme position in which a split collet (14) is supported, in an assembled condition and fills a conical cavity defined by a recess (9) in the sleeve and a nose portion (6) of the body member. An anchorage (16), attached to the load, is held in a stable position by the collet. When the parachute and load exert opposing forces on the mechanism the sleeve moves relative to the body member against the action of spring (13) thus increasing the size of the cavity and is locked by a double acting, spring loaded plunger (8). When the forces are removed after landing the collet is urged by spring (15) away from its sealing in the sleeve and can assume an unassembled condition in the enlarged cavity, thus releasing the anchorage and the load. <IMAGE>

Title: Printed circuit board inspection
Inventor: COLLINS RODERICK JEFFREY WATER
IPC: G01N21/956
Filed: 1982-07-22
Abstract: Computer-controlled Automatic Visual Inspection offers a solution to the present-day difficulties of checking modern high density printed circuit boards (and their artwork masters) if only there can be found a way of reducing the masses of data involved. The present invention provides a visual inspection method (suitable for computer-controlled operation) in which, instead of comparing the whole board (or artwork master) with the "master version" on a smallest- point-by-smallest-point basis, portions of the whole are examined one by one for track/space faults, and are compared with the "master version" of that portion not as regards the totality of information within that portion but as regards specific features of the circuit therewithin that are in themselves sufficient to define the circuit, namely the location of track junctions and track nodes. The figure shows the sequence of portions 1-18 examined in the case of a master, providing node and junction positions, the track interconnection pattern, and the position of any width fault. For the corresponding circuit board, the portion sequence follows a boustrophedral scan pattern. <IMAGE>

Title: Method and apparatus for the production of rod-shaped articles of the tobacco processing industry
Inventor: HELMS DR ADOLF
IPC: G01N24/00
Filed: 1983-04-28
Abstract: Filter rod sections are automatically diverted at intervals from a file of filter rod sections into the testing station of a nuclear magnetic resonance testing device which ascertains the percentage of plasticizer in the sections and generates signals which are used to indicate the percentage of plasticizer and/or to automatically regulate the rate of admission of plasticizer to the solid component of the filler which is thereupon converted into a filter rod. The filter rod is severed to produce the file of filter rod sections. Freshly tested filter rod sections are automatically removed from the testing station and are reintroduced into the file. The testing station can also receive batches of tobacco particles which are automatically diverted from a continuous tobacco stream, and the results of tests are indicative of the moisture content of tobacco which is about to be converted into the filler of a cigarette rod. <IMAGE>
