Title: A process for use in the production of a semi-conductor device
IPC: H01L21/00
Filed: 1960-11-21
Abstract: 935,484. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. Nov. 21, 1960 [Nov. 21, 1959], No. 40026/60. Class 37. During manufacture of a semi-conductor device a semi-conductor body is so doped that a doping layer extends into and over an entire surface of the body, the rest of the body being substantially unaffected by the doping, and a marginal region of the layer is subsequently removed so that a portion of the body surrounding the layer is left unexposed. In the construction shown in Fig. 4 a body of silicon of resistivity 200 ohm cms. has a layer 4 of goldantimony alloyed to it, the resistivity of this region being 80 ohm cms. and in the centre of the region is a more heavily doped (0.01 ohm cms.) N-type region 2. The edge of layer 4 is removed where shown dotted by centrifugal etching before or after the production of region 2, and this is said to maintain the width of the space charge zone even though negative ions are adsorbed on the surface. A P region 7 may be alloyed to the opposite face of the device. The conductivity type of the various regions may be reversed.

Title: Logic array with testing circuitry
IPC: G06F11/10
Filed: 1975-10-01
Abstract: 1475255 Selective signalling INTERNATIONAL BUSINESS MACHINES CORP 1 Oct 1975 [18 Dec 1974] 40080/75 Heading G4H A logic array with testing apparatus comprises a plurality of decoders feeding input lines of a logic-performing matrix, the matrix incorporating a check line intersecting the input lines for storing information on the number of operative logic means located along each of the input lines.  In Fig. 1, input bits at 14 are decoded in pairs by decoders 12a, 12b ... 12, each decoder selecting one of a respective 4 row lines of an AND array 10. The array 10 has FETs at selected row-column intersections to provide on each column line the AND of a respective combination of the row lines. The column lines feed an OR array 24 which similarly has FETs at selected row-column intersections and feeds latches via its row lines. The AND array has an extra column line 21 specifying a parity bit for each row line according to the number of FETs which should be present in it, and the OR array has an extra row line 19 specifying a parity bit for each column line. To test the AND array, a command decoder 36 is used to enable the decoders 12a, 12b ... 12 in turn, each decoder, when enabled, being supplied with appropriate inputs to select all its outputs in turn. As each row line of the AND array is thus selected, the column outputs are loaded into a shift register 48 and parity-checked by an EXCL-OR tree 50. The OR array is then tested by decoupling the two arrays using a mask output 40 of the command decoder 36, and inserting a 1 into the shift register 48 and shifting it along thus selecting the column lines of the OR array in turn, the row outputs being parity-checked in each case by an EXCL-OR tree 54. Another output 42 of the command decoder 36 (used e.g. for normal operation) enables all the decoders 12a, 12b ... 12 and resets the shift register 48. EXCL-ORing may be done serially. Extra redundancy lines could be provided in the arrays.

Title: Tube connecting members
Inventor: HEATHCOTE JOHN
IPC: F28F9/26
Filed: 1962-10-24
Abstract: 991,914. Tube connectors. FOSTER WHEELER Ltd. Oct. 18, 1963 [Oct. 24, 1962], No. 40293/62. Heading F2G. [Also in Division F4] A tube connector 12 comprises a base plate 14 having formed in one of its faces an opentopped groove 16 which does not extend to the edge of the plate and a closure plate 18 adapted to be fixed to the base plate and having in it holes communicating with the groove so that tubes 10 fixed to the closure plate in communication with the holes will be in communication with each other through the groove. In the embodiment shown in Fig. 1, tube connectors 12 are connected by tubes 10, forming a two-dimensional cluster, and as the tube connectors are arranged their grooves are off-set by one tube pitch with the result that each tube 10 is put into series connection with an adjacent tube, the circulating fluid entering by a hole 24 in one base plate and leaving by a hole 24 in the other base plate. The ends of the tubes are welded to tubular studs machined on the plates 18 and counterbored to receive the ends of the tubes, this construction allowing the tubes to be close together and so being advantageous for heat exchange. Grooves may be arranged to put any number of tubes in series connection with an equal or different number of tubes, or to connect tubes in parallel. The base plate, instead of having grooves, may have a depression of other geometrical shape, e.g. triangular (Fig. 7, not shown), in which two tubes are put in communication with a third. In an embodiment illustrated in Fig. 4 (not shown) a composite heat exchange unit comprises three clusters of tubes and connectors, the end two clusters each having nineteen tubes connected in series, the central cluster having nineteen tubes connected in parallel. The inlet and outlet manifolds of the heat exchange unit require adequate wall thickness for the pressure, and the tube pitch in the manifold may be less than the tube pitch in the cluster. To accommodate this difference the tubes may be bent and spacers used as disclosed in Specification 991,915. A base-plate for connecting 19 tubes in series, wherein the grooves are so arranged that tubes fixed to a closure plate having pairs of holes communicating with the opposite ends of each groove will be uniformly pitched and will form a hexagonal cluster is illustrated in Fig. 3 (not shown). Specification 934,485 also is referred to.

Filed: 1969-08-18
Abstract: 1284937 Knitting; finishing pile fabrics W BINDER 18 Aug 1969 [26 Aug 1968 17 Dec 1968] 41145/69 Headings D1C D1K and D1S A pile fabric comprises a thermoplastic yarn knitted to form long loops which are set, cut in one limb to form a barb and errected. The errected barbs so formed engage a loop pile fabric so that they together form a fastener. A weft knitted fabric comprises a basic yarn 3 knit on one bed only of a two bed machine and the thermoplastic yarn 6 knitted on that bed but held over several courses in wales 6" knit on the other. Courses of the thermoplastic yarn may be joined by an additional removable yarn 7. The fabric is then stretched and heated to take the desired shape, and cooled whereafter the held loops are cut at one side of the loop head, after removal of the additional thread if present. The fabric is stretched again to errect the barbs and then sized. Some or all of the courses of basic yarn may be knit with elastic yarn. Warp knitted fabrics may be knitted on a single or a double needle bed machine. In fabrics knit on a single bed the pile yarn is knit in spaced courses, and loops are formed by laps around pile instruments. If the fabric is knit on a two bed machine the pile-forming yarn 16 is anchored in the base fabric by knitting in one bed, and forms open loops 16" in spaced courses on the other. The open, pile-forming loops may be joined by a further yarn 17, which is removed to release the loops. Alternatively the pile loops joining one-another are run. In one arrangement for knitting a warp fabric the long loops are passed around hooks 102 when they lap the needles. Sets of hooks are mounted in a rotatable drum 105 and projected by oil pressure. The oil is heated so that the loops are set as they are drawn by the hooks. In an alternative embodiment the long loops are layed around members (132 Fig. 16 not shown) behind the needles and projecting above the comb plate. The loops are set by a heater while on the members.
