Title: Microprogramming control apparatus
IPC: G06F9/28
Filed: 1974-12-06
Abstract: 1465159 Addressing memories FUJITSU Ltd 6 Dec 1974 [7 Dec 1973] 52954/74 Heading G4A Control memory banks holding micro instructions are accessed sequentially, with overlapping operations on the memory banks. In the embodiment of Fig. 4 the address section AR of a micro instruction held in data register DR is applied at time t 1  in dependence on the value of a bank designation bit to one of two address registers AHR0, AHR1, each associated with a memory bank BK0, BK1 respectively to cause read-out at time t 3  of a pair of micro instructions, one of which is selected (in accordance with whether a previous instruction has necessitated a branch) for read-in to the data register DR to provide the address for the next micro instruction for the same bank. Alternatively, at time t 2 , a second of the address registers accesses its memory bank so that at time t 4  the address of the next micro instruction may be applied to this other memory bank. A branch operation results in a bi-stable ID being set to enable one of two sets of 32 AND gates AND 1, AND 2 to apply the selected micro instruction to data register DR. Thirteen bits (0-12) of the instruction which represent a new address are fed to address register AR, 12 of these bits being fed via AND gates AND 3, AND 4 to one of the registers in accordance with the value of the 13th bit (the bank designation bit). Bits 13-16 are branch function controlled-for example 0100 indicates the bi-stable ID is to be set if a carry occurs-and bits 17-31 are applied to a decoder to provide control signals for arithmetic and logic operations. In a second embodiment (Fig. 12, not shown), in which 4 memory banks are used, with 2 bits of the 13 bit address being used for bank designation, the accessing of 4 micro instructions over-lap.

Title: Semiconductor light emitting devices
IPC: H01L33/16
Filed: 1974-12-09
Abstract: 1494348 Electroluminescence WESTERN ELECTRIC CO Inc 9 Dec 1974 [10 Dec 1973] 53088/74 Heading C4S [Also in Division H1] The N type zone of an indium phosphide PN junction diode capable of emitting infra-red radiation contains tin donor atoms partially compensated by cadmium acceptor atoms the doping being such as to shift the wavelength peak emission intensity to a value between 0À925 and 1À1 Á. In a preferred embodiment the N type zone is deposited by liquid phase epitaxy on a 100, 111 or 110 orientated face of a cadmium or zinc doped P type indium phosphide body having a hole concentration of not more than 5 Î 10<SP>17</SP> holes/cm.<SP>3</SP>. The deposition step is performed in a sealed capsule as described in Specification 1,450,433 but using a presaturated melt richer in indium phosphide. After flooding the body the melt is cooled, typically at from 4-15 C. per hour. The cadmium and tin doping lowers the band gap of the P type region to give high quantum efficiency production of radiation having a wavelength up to 1À1 Á, which matches the low loss window of a fused silica glass optic fibre. Forward resistance of the diode may be lowered by substituting for the P type body a thin layer on a low resistivity substrate of indium phosphide.

The glass fibres 24 are drawn through a perforated orifice plate 23 of Ti, Pt or ceramic in the bottom of a glass melting tank 10 by means of two rollers 26 and 27, the fibres being guided to and from the rollers by guide blocks 44 and 45 located above and below the rollers, respectively and each having a plurality of orifices therein, one for each fibre 4. Roller 26 is rotatably driven by a motor 43 acting through a pulley and belt 40, while the roller 27 is spring biased against roller 26. Each roller has a resilient covering of, for example, neoprene rubber. A burner 50 located below the block 45, which produces a high temperature, low velocity flame, thus heating the glass fibre ends to produce molten beads, and providing a gas flow which causes the beads to separate from the fibre ends and directs them into a liquid quenching medium 56. The quenching medium may be water, oil or an organic solvent. The rollers 26, 27 may be cooled either by an internal liquid or gas cooling means or by spraying the space between the rollers with water. The production of the glass fibres can be a separate step and the fibres subsequently being fed through a guide block into the heating zone.

Abstract: 1462844 Tachogenerators EATON CORP 19 Dec 1974 [27 Dec 1973] 54938/74 Heading G1N A transducer for measuring the angular velocity of a wheel 50, Fig. 2, comprises a toothed ring rotor 26 attached to the wheel, spaced by an airgap 64 from a stator assembly 28, wherein the induced voltage in a pick-up coil has a frequency proportional to the angular velocity. The stator 28 comprises an E-shaped core 100, Fig. 3,  whose centre leg 106 is a permanent magnet, and the spacing between the outer legs 104, 108 is such that when one faces a rotor tooth 70, the other faces a gap 66. Each outer leg carries a winding 162, 164, connected in series opposition, so that when the wheel is rotating an increase in flux in leg 104 coincides with a decrease in flux in leg 106, the induced voltages in coils 162, 164 are opposite in phase and therefore added by the series opposition connection. Changes in the air-gap 64 due to axial vibration produce in phase flux changes in the legs 104, 106 and are thus automatically cancelled out in the induced voltages. Alternative forms of the stator core are shown, and the stator assembly is suitably encapsulated.

The master file text may be a statute, regulation or the like which is divided into numbered sections, sub-sections, clauses and so on, each line having an ordered set of identifiers e.g. from section number down to line number, and the master file is updated from the processed revision file.  The revision file is analysed to determine which part of the master file is to be revised and the operations which have to be performed on the master file text. Statements from the revision file are stored for comparison with a stored table of descriptors to identify the descriptors in the revision file and to effect storage of the immediately following word containing the value of the descriptor. Similar comparisons with stored data to identify text to be revised and operations to be performed are also made. Addition, deletion and replacement of individual words or text passages may be effected by merging text from the master and revision files to form a new master file, and a history trace file is also kept to enable the text existant at any given time to be determined.
