Filed: 1972-06-27
Abstract: 1345658 Semi-conductor data storage cells COMPAGNIE INTERNATIONALE POUK L'INFORMATIQUE 27 June 1972 [29 June 1971] 30134/72 Heading H3T [Also in Division G4] A column of complementary transistor storage cells Fig. 2 and PM, Fig. 10, share a common load resistor R c  whose value is effectively reduced during reading and writing to reduce the switching time of a selected cell. The resistor R c  is shunted by a transistor T cc  when column select circuitry SC raises T cs  emitters' voltages. Selection of a particular cell in a column for writing purposes is by supplying from SL a pulse which is long enough to switch on the transistors of a cell whose switching time has been reduced, but not long enough to affect the other cells. Absence of such a pulse writes "0". To read, the appropriate gate G 0  to G 7  is enabled by SL, and the increase of current in a conductive cell when its associated R c  is reduced, is detected by an OR gate U. The NPN transistor of each cell may have two emitters (Fig. 3, not shown) one of which (6) is connected to the transistor T cc  (Fig. 11, not shown) and the other (2) to the load resistor whereby groups of cells may share respective load resistors (R co ). The matrix is integrated.

Title: Improvements in and relating to high frequency electrical coils, more particularly applicable to wireless aerial coils
IPC: H01F27/36
Filed: 1921-11-11
Abstract: 192,795. Preston, L. G., and Shuttleworth, N. Nov. 11, 1921. Transmitting systems and apparatus; coupling oscillating and radiating circuits.-Inductance coils carrying large high-frequency currents, more especially coils employed in wireless transmitting apparatus, are protected from the deleterious effects of outside influences such as metalwork, by partially or wholly enclosing them by coils, bars, strips or boxes of copper or other conducting metal; or a combination of coils and boxes may be used. When coils are employed the wire used is finely stranded, the strands being insulated from one another. Fig. 1 (Prov.) shows an aerial inductance A enclosed by a cylindrical short-circuited coil B and short-circuited pancake coils C. Aiternatively, the coils may be reduced to a common potential by connecting them to one point, conveniently earth. According to a modification, the cylindrical coil B and a pancake coil C are continuously wound from one piece of wire. A modification is also described in which the coil A is surrounded by a copper box. Fig. 1 (Comp.) illustrates a further modification in which the projecting coil B is shortcircuited through an inductance H which is coupled to the grid circuit G of a valve transmitter. If the coil H is of high inductance it is stated further to decrease losses due to disturbing factors. An aerial coil with its protecting coil may also be enclosed in a copper box filled with insulating oil, in which case the protecting coil is short-circuited as before, or is connected to the box and both earthed.

Title: Control apparatus

Filed: 1972-06-28
Abstract: 1428126 Retro-active position control SPERRY RAND Ltd 8 June 1973 [28 June 1972] 30237/72 Heading G3N In a position controlling servo system an error signal is derived representing the difference between a desired position and an actual position; the error signal is converted into a pulsed control signal and to ensure that unwanted long period fluctuations do not occur in the control signal its integral is compared with that of the error signal and any differences are used to correct the control signal. In Fig. 1 a desired position is fed to input 9 and passes via amplifier 8 to comparator 5. At the comparator the input signal is combined with a triangular wave 13 to give a pulse length modulated control signal which is amplified at 17 and drives a hydraulic or pneumatic valve 1 to operate actuator 2. A movable body 3 is thus driven towards a desired position, its actual position being detected by potentiometer 6 and subtracted from the input signal at 8 to give an error signal on line 12. This error signal and the control signal are fed to integrator 11 where their integrals are substracted to form a correction signal on line 14 which determines the production of the control signal at comparator 5. In the alternative embodiment of Fig. 2 the error signal from subtractor 8 is fed to integrator 11, the output of which controls a flip-flop 18. This latter generates the control signal which passes to amplifier 17 as above and also to the integrator 11. In this case the frequency of the control signal varies with the magnitude of the error signal, while in Fig. 1 the frequency is constant.

Title: Improvements in or relating to the production of oxide layers on silicon bodies
IPC: H01L21/00
Filed: 1965-07-19
Abstract: A layer of SiO2 is produced on the surface of a monocrystalline Si body by first subjecting the body to the action of a gaseous reactant to remove a surface layer of Si, then rinsing with an inert gas, and oxidizing the Si surface with O2 or H2O vapour.  The gaseous reactant may be a halogen or a hydrogen halide, e.g. HCL, and may be diluted with H2 or Ar.  The removal of the Si layer may be effected by a transport reaction between the Si surface and the adjacent surface of a parallel cover-plate spaced at a distance of 0.1-1 mm. away and maintained at a temperature 15-30 DEG  C. lower than the Si body. In this case, a halogen compound of Si, e.g. SiCl4 or SiHCl3 may be used, preferably mixed with H2 in the ratio 0.01 : 1 to 0.05 : 1; it decomposes in the hot parts of the vessel to deposit Si and form HCl, which then acts as the transport gas.  The cover-plate may be made of Si, or quartz, SiC, or graphite, which may be coated with Si.  It may rest on the Si body, be separated by a spacer, or be arranged freely, and is preferably removed before oxidation. A plurality of Si bodies may be treated by using a single cover-plate with slots between the bodies, or by stacking the bodies vertically so that each acts as a cover-plate for the next. The inert rinsing gas may be N2, H2 or a rare gas, e.g. Ar.  The water vapour oxidant may be carried by H2 or a rare gas.  The temperature of the Si body may be 1100-1250 DEG  C. during etching, 1150-1200 DEG  C. during rinsing, and 900-1150 DEG C. during oxidation.  A continuous flow or closed system may be used.
