Abstract: 1,234,583. Colour television tubes. SONY CORP. 18 Sept.. 1968 [20 Sept., 1967 (2)], No. 44315/68. Heading H1D. In a colour television tube using red, blue and green phosphors, a larger exciting beam current must be applied to the green phosphor than to the other two phosphors to produce white light, and this is achieved by making the control grid aperture for the green beam of larger diameter than the apertures for the other two beams. A triple electron gun may have a common cathode and separate control grids, Figs. 4 and 5 (not shown), or separate cathodes and a common control grid, Figs. 6 and 7 (not shown). The larger aperture for the green beam makes the cut-off voltage lower, and this is avoided by covering the aperture with a diametral strip (Figs. 8 and 9, not shown) or with a.spider's web arrangement (Figs. 10-13, not -shown). As described the gun is applied to a tube using coplanar beams, the outer beams being converged at the plane of a beam selecting grid or mask by a fixed deflecting system, Fig. 1 (not shown). The central beam is the green beam, and the outer beams pass through the peripheral :portions of - an electrostatic focusing lens so that they are subject to spherical aberration, and consequently the spot sizes of the three beams are about the same.

Abstract: 1,238,815. Automatic gain control. SYLVANIA ELECTRIC PRODUCTS Inc. 1 April, 1970 [1 April, 1969], No. 15479/70. Heading H3T. An automatic gain control circuit for a television receiver comprises a first input terminal for connection to a video signal source, a second input terminal for connection to a gating pulse source, an amplifier having an input connected to the first input terminal, a first diode connecting the second input terminal to the amplifier, and a second diode connecting the amplifier to an output terminal. Video signals, of which the sync. pulses comprise the most negative-going component, are applied from detector 11 to the base of an amplifier 23, the collector circuit of which feeds the picture tube. Signals are also taken from the emitter circuit and fed to the base of an A.G.C. gate transistor 37, via a resistor 29, to which is coupled a noise-suppression transistor 33. Transistor 33 is normally saturated but is driven from detector 11 so that on noise impulses corresponding positive-going pulses appear in its collector circuit and cancel out the corresponding negative-going noise pulses derived from transistor 23. The collector of the A.G.C. gate transistor 37 is driven with pulses comprising either line flyback or colour burst pulses, via diode 43, and the resultant changes in collector potential are passed by a diode 51 to smoothing circuit 53, 55. The smoothed potential across this is fed via emitterfollower 57 to control the R.F. and I.F. stages of the receiver.

Abstract: 1,251,378. Semi-conductor devices. MARCONI CO. Ltd. 14 March, 1969 [30 April, 1968] No. 20335/68. Heading H1K. In making a semi-conductor device a surface of a silicon wafer is oxidized and the oxide coated with a glass which while allowing access of oxygen to form a further oxide layer beneath the existing oxide bars the entry of detrimental impurities. The glass is subsequently removed and contacts formed on the silicon. Contact formation and any other processes subsequent to removal of the glass are performed in such a way as to avoid contamination of the further oxide. The invention is described applied to manufacture of a MOSFET. The oxide, glass and further oxide layers are first formed on an N- type Si wafer to respective thicknesses of 2000 Š, 1000 Š and 1 Á. Holes are cut through the layers by photolithography and boron deposited and diffused in to form source and drain regions overlain by thin layers of oxide. The layers overlying the gate region are then removed to a thickness of 1300 Š and aluminium deposited to form source, drain and gate contacts to which lead wires are welded.

The angle of the taper surface 2 may be 24 degrees and the breadth of the face of the annular edge 8a may be 2/3 of the breadth of the annular face 7a, the spacing between the edges being 4 times the breadth of the face 7a.
