IPC: H03M1/34
Filed: 1966-10-17
Abstract: 1,128,084. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 17 Oct., 1966, No. 46295/66. Heading G4H. [Also in Division H1] An analogue-to-digital converter comprises a body 1, Fig. 6, of semi-conductive material exhibiting high field instability effects, the resistance of the conducting cross-sectional area being increased along the major axis, there being electrodes 2, 3 between which is applied a potential difference to produce a steady electric field which is normally less than the instability threshold, the field being increased in response to an input signal to a value exceeding the instability threshold value, at least locally within the body, to form a high field domain within the body which propagates therealong before extinguishing a distance determined by the magnitude of the input signal. Pulse generating means are provided which when encountered by the propagating high field domain produces a series of output pulses. It is arranged that the last n of these pulses before the high field domain extinguishes are in the form of a digital pattern representing the magnitude of the input signal. The output pulses may be produced by grooves 4 air-abraded or etched into the body. Two sets 'of grooves may be made, Fig. 10, to form a coded pattern of "1"s and "0"s. Alternatively the regions of different resistivity may be made by doping alternate areas 8, 9, 10 etc., Fig. 7. The intermediate areas 7 all have the same value. Extra electrodes 15, Fig. 8, may be provided insulated from the body by layer 22. The high field domain takes the form of sharp current pulses and it is sensed capacitively by the electrodes 15 in turn. To obtain the last n digits the output from the converter 16, Fig. 11 is applied via a delay 17 to a gate 18. The delay stores the last n digits, the gate being operated when the high field domain extinguishes to pass them to the output.

Filed: 1968-10-15
Abstract: 1,243,831. Resiliently-mounted seats. K. G. NYSTROM. 15 Oct., 1968 [17 Oct., 1967; 23 Aug., 1968], No. 48902/68. Heading A4U. In a tractor seat which is counterbalanced by a tension spring 26, pulling down on the end of lever 24, the mechanical advantage of the lever, which is fulcrummed on a fixed pivot 30, is selfadjusting in accordance with the static weight of the seat occupant. Locks are provided to block the actions of tension springs 23 and 26, alternatively. Thus, spring 23 is normally blocked by the frictional engagement of tapered pivot head 30 with the edges of slot 29, while spring 26 is free to counterbalance the weight of the seat 16 and occupant. On raising latch 54, the blocking is reversed, through Bowden cable (53) turning lever 62 into the full-line position (to abut nose 61 and thereby block spring 26) and moving pivot 30 axially, to release the edges of slot 29. If the seat is unoccupied, spring 23 pulls lever 24 into the full-line position. On applying a load to the seat, lever 57 it tilted about the tip of lever 62, so that the parts move towards the dotted line position; the extent of movement depending on the extension of spring 23, which is required to counterbalance the load applied to the seat. On lowering latch 54, pivot 30 again grips the edges of slot 29 to block the action of spring 23 and lever 62 is retracted, to re-enable spring 26 to support the seat. In another form, levers (19, 20, Figs. 1-6, not shown) are mounted on an intermediate mounting plate (13) and replace lever 57, which is carried directly on the seat 16. In an alternative construction, a triangular plate (116, Figs. 9-12, not shown) replaces lever 24.

Abstract: 1453723 Addressing systems HONEYWELL INFORMATION SYSTEMS Inc 22 Oct 1973 [29 Dec 1972] 49121/73 Heading G4A To extend the address for a main memory address register 76 (Fig. 2) in a digital computer system, the address from an instruction register 78 may be combined in a base address adder 170 with the address from base address register 120, extension register 110, or master base address registers 130, 140. The system permits the span of the address field to be extended beyond the span of the instruction address field for both operands and instructions. When the processor is executing instructions in the core resident operating system the absolute address is the same as the effective address from the instruction register. The processor may execute either a user slave program instruction in which case the instruction and operand addresses (i.e. the effective addresses) fed via switch 19 are modified in base address adder 170 by the contents of base address register 120 or an operating system master mode program instruction in which case the addresses are normally modified by the contents of master base address register 130, master mode base address register 140 being used for special accumulator load/store operation. Control logic (the control for one bit being given in Fig. 4, not shown) receives as its input the output of decoder 79 connected to instruction register 78 and derives an output signal from one of three gates (52, 58, 57) indicating that modification is to be effected by the contents of registers 110, 130, 140 respectively. The control logic also generates signals to control the loading of the four registers 110, 120, 130, 140.

Abstract: 1,074,287. Semi-conductor devices. MULLARD Ltd. Dec. 13, 1963, No. 49355/63. Heading H1K. [Also in Division H3] A transistor has a base region comprising a thicker part and a thinner part situated beneath the emitter region and two base contacts, the arrangement being such that the major part of the emitter current can be caused to flow through either the thicker or the thinner part of the base region depending on the bias voltage between the base contacts. As shown, Figs. 1 and 2, a transistor similar to that described in Specification 1,074,032 but with the base region arranged as above is manufactured using the planar process. Boron is diffused into a P-type silicon wafer 2, doped with phosphorus, to form the thicker part 8 of the base region. Phosphorus is then diffused into the surface of the wafer, except the portions enclosed by chain-cross lines in Fig. 1, to form a more highly doped collector region 1. Boron is again diffused into the surface to form the thinner part 4 of the base region and phosphorus is again diffused-in to form the emitter region 3. Aluminium contacts 9, 10, 11 are then alloyed to the emitter region and to both ends of the base region respectively. A plurality of devices may be simultaneously manufactured in a single slice of semi-conductor and then divided up. Gold wires are attached to contacts 9, 10, 11 by thermocompression bonding and the lower face of the wafer is ground to the required thickness and secured to a gold-plated Ni-Fe header. In a second embodiment, Figs. 4, 5 and 6 (not shown) the regions are formed, in plan view, as concentric circles. In a further embodiment, Fig. 7, a wafer 2 of N-type silicon has a more highly doped N-type layer 1 produced by diffusing-in phosphorus. Base regions 4D, 4S are formed by diffusing boron into the surface in two separate stages. Phosphorus is then diffused-in to form emitter region 3. In any of the embodiments one or more of the regions may be formed by epitaxial deposition. The relative bias on the two base contacts determines the proportion of the emitter current which passes through the two parts of the base region and hence controls the gain of the transistor. An automatic gain control circuit using this characteristic is described (see Division H3).

Before cross-coupled FETs 3, 4 are set by input signals at 1, 2, the feedback cross-couplings are disabled by turning off FETs 12, 13; and further FETs 14, 15 are turned on to connect T3, T4 drains to their own gates. The voltage supply at 9, 8 is then reversed to turn off the bi-stable, and the further FETs 14, 15 are then turned off. The inputs 1, 2 are now permitted to change, and the voltage supply is restored. Finally, cross-coupling through FETs 12, 13 is re-established. The inputs may be applied alternatively to FETs 3, 4 gates (Fig. 6, not shown). These inputs are derived from a data storage cell (not shown) whose state is thereby refreshed.
