Title: Improvements in or relating to silicon semi-conductors
Inventor: MESSIER JEAN
IPC: H01L27/00
Filed: 1962-11-26
Abstract: 979, 844. Transmutation of elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 26, 1962 [Nov. 24, 1961; Nov. 14,1962], No. 44649/62. Heading G6P. [Also in Division H1] In a process of preparing intrinsic silicon from low P conductivity silicon formed by the floating zone method, an initial sample having a resistivity # of at least 900 ohm cm. is subjected to thermal neutron bombardment at an integrated flux per sq. cm. of 7 x 10<SP>19</SP>/#. The thermal neutrons convert some of the silicon into phosphorus which has sufficient N conductivity to balance the initial P conductivity. After irradiation the silicon should be annealed by heating to at least 500‹C., e.g. 550‹C., for at least 12 hours. In one example the initial resistivity is 5000 ohm cm. and after treatment as above the resistivity is 50, 000 ohm cm. Small quantities of donor and acceptor materials are then fixed to the faces 3, 4 of the silicon block 1 and diffused into the block by heat treatment in a neutral atmosphere followed by a cooling stage wherein the temperature is reduced by at least 5‹C. per minute. In this way there are formed N and P conduction regions at each end separated by a thick intrinsic region, the total thickness being 4 mm. Electrodes 9 and 11 are secured by gold eutectics, and the diode so formed can withstand high inverse voltages, e.g. 20 kV, and is suitable for use as an H.T. rectifier in a television receiver. Discharges between the electrodes along the surface of the element 1 .can be prevented by coating the surface with resin, by oxidising the surface, by immersion in a silicone oil, or by disposing the element in an evacuated envelope. The diqde may alternatively be used for detecting ionising radiation.

Title: Record storage system
IPC: G06F12/08
Filed: 1965-10-29
Abstract: 1,090,680. Storage system. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 29, 1965 [Nov. 13, 1964], No. 45801/65. Heading G4C. An hierarchical - organized record storage system, i.e. one having a plurality of storage levels having graded characteristics, e.g. of accessibility, each level having a plurality of record storage positions, includes means for storing an input record in at least one selected level, means for rearranging the stored records between the levels on an empirical basis, and means operative at any given time for determining the level and position in that level at which a desired record is stored, and for accessing the desired record. In the arrangement shown in Fig. 1 the plurality of storage levels comprise a magnetic drum HR0 and three loop (e.g. magnetic tape loop) stores HR1, HR2 and HR3. The access time increases progressively from store HR0 to HR3. When it is required to enter a new record from host core memory 52 hierarchy processor and directory 26 allocates a relative address (from a location address counter 156 Fig. 2, not shown) thereto and the record data is then transmitted along bus 32 to a loop write station 34 and also to the drum HR0. A directory of relative addresses and record names is compiled. After the writing is finished or (if several records can be accommodated on each loop) after a loop has been filled, the loop is physically transferred through tube 38 to store HR1. If store HR1 is full then the oldest loop is passed out through tube 40 to store HR2 where it occupies the first vacant position. If no vacancy exists in HR2 then the oldest loop is passed out through tube 42, and so on. Loops are eventually pushed out of the system through tube 44 to an archive store (not shown). The loop storage device (Fig. 5, not shown) is the subject of Specification 1,051,779. When it is required to read a record into memory 52, processor 26 obtains the absolute address of the record by a calculation involving the difference between the relative address being assigned to new records and that of the record to be retrieved (obtained from the directory). Bus 30 transmits the read address signals and bus 46 the data read. In a second embodiment, incoming records can be directed into levels as desired, a second directory being used to enable records to be read at a later time. Further storage capacity may be added to any level without upsetting the relative addresses already allocated. Circuit details for both embodiments are given. The loop stores, which are preferably magnetic, may be replaced by magnetic drums, core matrices or discs.

Abstract: 1,221,273. Colour television tubes. ZENITH RADIO CORP. 18 Sept., 1969 [24 Oct., 1968], No. 46126/69. Heading HID. A shadow mask 31 for a colour television tube is provided with an adjacent mesh electrode 32 having interstitial dimensions small compared with the aperture dimensions of the mask, the two electrodes being separately energized to form a lens focusing the beam or beams on to the fluorescent screen. In Fig. 2 the mask 31 is coated with insulation 33 which may be aluminium oxide formed by anodizing if the mask is of aluminium or aluminium-coated steel, and the insulation is coated with a semiconductor 34 such as chrome oxide to prevent charges accumulating on it. The electrode 32 may be a woven, knitted, expanded metal or electro-formed mesh and is secured to the layer 34 by means of an adhesive. In an alternative construction, Fig. 3 (not shown), insulation such as silicon dioxide or nitride is applied to one surface of the mesh 32 which is then secured by an adhesive directly to the mask 31 without the intervening layers 33 and 34. The mask is mounted in the tube with the mesh 32 facing the electron beams and electrically connected to a wall coating on the cone of the tube; the mask itself is electrically connected to a wall coating on the face panel of the tube, possibly through the usual support means. In operation the mesh may be maintained at 25 Kv. and the mask at 24-8 Kv., the lower potential of the mask and screen ensuring that any secondary emission is directed away from the screen. The arrangement described constitutes a two-element lens for focusing the beam or beams on the screen; a three-element lens may be formed by providing another mesh electrode on the opposite side of the mask.

Abstract: 1,211,970. Control of D.C. motors. SINGER CO. 23 Sept., 1969 [24 Oct., 1968], No. 46710/69. Heading H2J. A sewing machine has an armshaft 11 driven by motor 12, a reed switch 14 being influenced by a permanent magnet 15 to be held closed when the shaft is within a given angular range. The motor is supplied through SCR 20 when switch 35 is closed in the actuated position of a foot controller 29, the switch being linked with a potentiometer 32 for controlling the speed of the motor. When the switch 35 is opened, SCR 21 becomes conductive and current continues to be supplied to the motor under the control of SCR 20 for operation at a fixed low speed determined by a reference voltage derived from resistor 30. The SCR 21 is triggered by discharge of capacitor 25 through resistor 28 into gate 55. The switch 14 closes when the shaft 11 reaches a desired angular position and the SCR 21 is turned-off on the next occurrence of zero anode voltage, the switch 14 remaining closed for a number of degrees of shaft rotation to bring the machine to a full stop. Shortly afterwards, the capacitor 25 is fully discharged through switch 14 so that SCR 21 is not triggered into conduction even if the switch 14 is re-opened. In this condition the control system is isolated whereby the shaft 11 may be repositioned by rotation of handwheel 13 without danger of re-energizing the system. Subsequent actuation of the foot controller 29 re-closes the switch 35 and charges capacitor 25. Zener diode 34 stabilizes the reference voltage across lines 51, 52, whilst thermistor 23 stabilizes the operation of the SCR 20. In modifications, the SGR 21 is replaced by a transistor or a time-delay relay, Figs. 2, 3 (not shown).
