Patent GB-1411795-A (GB)
Title: Storage elements
IPC: H01L27/04
Filed: 1972-09-29
Abstract: 1411795 Semi-conductor devices SIEMENS AG 29 Sept 1972 [30 Sept 1971] 45015/72 Heading H1K A single transistor storage element comprises a transistor, e.g. F.E.T. 32 formed in a surface of semi-conductor substrate 31 and a capacitor formed by an insulating layer 25 on substrate 31 and a conductive coating 28, with terminal 8, extending substantially to the periphery of layer 25, diffused zone 9 of opposite conductivity type to substrate 31 constituting the drain of transistor 32 and extending under the periphery of conductive coating 28. A voltage of appropriate magnitude and polarity applied between terminals 8 and 12 produces inversion boundary layer 14 in electrical connection with zone 9 and the device has blocking layer capacitance between layer 14 and substrate 31 as well as the capacitance between substrate 31 and conductive layer 28. Diffused zone 22 limits the extent of inversion layer 14 and preferably is continuous with zone 9 as an annular zone surrounding conductive layer 28. Alternatively (Fig. 1, not shown) the extent of layer 14 is limited by a thickening of the insulating layer. The source of transistor 32 is constituted by a further doped zone 35. In a storage matrix based on the Fig. 3 arrangement and shown in Fig. 4 (see also Fig. 5, not shown) an array of digit lines 135, 1135 and selector lines 60 are arranged at right angles to each other in different planes and insulated from each other, the digit lines comprising regions in the semi-conductor body doped to make them conductive, and each source electrode 35 of a transistor is a branch of a digit line. The capacitors are arranged in columns and rows with the conductive layers electrically interconnected, and the capacitors in a column are connected alternately through the transistors, to a digit line lying to the left and a digit line lying to the right. The gate electrode 34 of each transistor is connected to a selector line lying above the conductive layers 28 of a row of capacitors, which row is adjacent to and below the row of conductive layers containing that of the capacitor with the gate electrode is associated. Reference has been directed by the Comptroller to Specification 1,254,899.

Title: Conveyor belt system with positional transformation of  weight data
IPC: G01G11/18
Filed: 1974-10-18
Abstract: 1475180 Conveyer-belt weighing HYER INDUSTRIES Inc 18 Oct 1974 [21 Nov 1973] 45176/74 Heading G1N Position compensation apparatus for a conveyer belt comprises means for providing a first signal representing a characteristic of material on a portion of the belt when adjacent a first reference point; and means responsive to the first signal and to the belt motion to generate a train of pulses, each pulse representing a unit of weight of material on a belt portion adjacent a second reference point at the time of that pulse. A scale input sensor 52, for providing, e.g., a D.C. signal 52a proportional to the weight of material 21 on a unit length of a portion of a belt 12, is located at a first reference point 31 favourable to weighing accuracy, e.g. near the low-tension tail end 14 of the belt. An integrator 54, receiving the analogue weight signal 52a together with pulses 36a from a signal generator 36 representing units of belt travel, provides a train of pulses 30a, each pulse representing a unit of material weight passing the first point 31. The belt travel pulses 36a, which are arranged always to have more than twice the recurrence frequency of the weight pulses 30a, also gate a series of type D flip-flops SR-1, SR-2,... SR-D each constituting a stage of a shift register 42 and representing a unit increment of a distance L between the first point 31 and a second reference point 32 which may be the discharge end 16 of the belt. The repetition frequency of the pulses 40a emerging from the shift register 42 this represents the rate at which the material, accurately weighed as it passed the first reference point 31, is currently passing the second reference point 32. The apparatus may be coupled to a control subsystem, Fig. 3 (not shown), to enable material to be delivered at a predetermined rate or up to a predetermined quantity, or to blend materials in a predetermined ratio, Fig. 4 (not shown). The belt travel signal generator 36, Fig. 2, may be coupled to a tail-pulley shaft encoder at 22,  or, if the belt is driven by a synchronous motor 18, may respond to the frequency of the A.C. supply. In a modification, (not shown), a suitable first weight signal may be fed directly into the shift register, the integrator then receiving the outputs of the shift register and of the belt signal generator, to convert them into the stream of mass-flow pulses.

Title: Improvements relating to sound recording and transmission systems
Inventor: TRENDELL EDWARD GEORGE
IPC: H03G9/18
Filed: 1964-11-06
Abstract: 1,124,507. Compandors. ELECTRIC & MUSICAL INDUSTRIES Ltd. 5 Nov., 1965 [6 Nov., 1964], No. 45256/64. Addition to 1,044,003. Heading H4R. Transistor circuits are described for the compressor and expander of Specification 1,044,003, in which the signal is split into high and low frequency bands and only the high frequency band is compressed for transmission or recording. Compressor, Fig. 1, the high and low frequency bands are split by Norton filters the low frequency band being applied direct to a summing circuit while the high frequency band is applied to the summing circuit via a capacitor C6 and a divider circuit which includes a transformer T2 which shunts the signal feed path to an extent dependent on the impedance in the secondary circuit, which impedance is controlled by a signal derived from the output of the divider amplifier. The control signal is derived by feeding the output of the divider amplifier to a phase splitter comprising a pair of partial collector followers the antiphase outputs of which are fed to a D.C. restoring circuit, comprising capacitors C15 and C16 and the diodes they feed, so that the signals applied to the bases of the emitter coupled pair appears with its most positive excursion at earth potential. The output at the common emitter connection follows the more negative of the voltages set up across the diodes and this voltage is fed via an emitter follower to two different circuits, one, including capacitor C17, providing a short rise time and a long fall time, and the other providing an elongator circuit followed by an A.C. coupling so that the leading edge of the signal is selected, these signals being passed to a further emitter coupled circuit to select the most negative signal which is applied via a limiter and current drive circuit to control the impedance of the secondary of T2 and therefore the divider ratio. Expander, Fig. 2, is similar to the compressor except that the high frequency signal from the Norton filter is fed to the summing circuit via a multiplier which includes the primary of a transformer in series with the signal path, the loading on the secondary of the transformer being controlled by a signal derived from the output of the high pass section of the Norton filter via a control circuit similar to that used in the compressor.

Abstract: 1320412 Semi-conductor devices GENERAL ELECTRIC CO 25 Sept 1970 [2 Oct 1969] 45895/70 Heading H1K A subassembly consisting of a stack of semiconductor junction elements bonded together in series between a pair of junctionless low resistivity semi-conductor connectors is mounted with the connectors making low-resistance connection with the formed ends of conductors projecting up from a substrate into which they are moulded or stuck, or with conductors extending on to lands projecting from the surface of a substrate and on to which the connectors also extend, the low-resistance connections in either case being made by a mass of curable plastics containing conductive particles. The curing temperature of the plastics is below the softening temperature of the stack bonding material. In all cases the stack has a passivating coating and is encapsulated in a fabricated housing or in moulded plastics. The elements are etched and rinsed and the passivation applied after attaching the stack to the conductors. In assembling the Fig. 1 arrangement notched conductors 106 are forced apart to permit insertion of the stack between them. The conductive bonding material supplements the resulting pressure contact or, Fig. 2 (not shown), may replace it entirely. A cold setting resin loaded with silver, gold, or aluminium particles may be used but to avoid thermal stress in operation it is preferred to use a resin which is cured at a temperature above those occurring in operation. Suitable passivants are resins, glass and silicon oxide or nitride over oxide but silicone varnish with an overcoat of cold setting silicone resin is preferred. The moulded encapsulation is preferably of epoxy, silicone or phenolic resin. As shown the junction elements are of PN type, but use of PIN, PNP, NPN, and NPNP elements is also suggested.
