Title: Colour video signal generating apparatus
Inventor: KUROKAWA HIROMICHI
IPC: H04N9/077
Filed: 1968-06-10
Abstract: 1,224,902. Colour television. SONY CORP. 10 June, 1968 [10 June, 1967], No. 27482/68. Heading H4F. A filter 27 (Fig. 8) and a screen 8 combine to form images of an object O on a photo-conductive screen 2 of an image pick-up tube 3 in such a way that the images comprise a series of coloured areas corresponding to the various colour components of the light from the object, resulting in the production of a chrominance signal comprising component colour signals all included within the same frequency band. Means are also provided for forming index images on the photo-conductive screen 2 and for deriving therefrom amplitude-modulated index signals indicative of the position of the colour components in the chrominance signal, which signals have a frequency band different from that of the chrominance signal. In the embodiment shown the filter 27 comprises an array 27a (Fig. 6) of parallel red, green and blue stripes perpendicular to the line-scanning direction of the tube 3, and the screen 8 comprises a series of spaced cylindrical lenses parallel to these stripes, producing on the photo-conductive screen 2 a series of images of the object O divided into separate colour components. The spaces in the screen between the lenses provide a series of panchromatic images superimposed upon the colour stripes from which images luminance signal is derived. A portion 27c of the filter 27 provides the necessary colour correction for this signal. The index image is formed by a portion 27b of the filter 27, in which transparent areas 27w, 27W produce images on the screen 2 which respectively give rise to the amplitude-modulated index signal and a constant D.C. level superimposed upon this signal. In another embodiment the index signal is amplitude-modulated by a square wave by the provision of a different pattern of transparent areas in the portion (47b), Fig. 9 (not shown), of the filter (47). The composite colour video signal from the pick-up tube 3, Fig. 8, is amplified by a video amplifier 12 and passes to a low-pass filter 13 which selects the luminance signal for frequency correction by a circuit 16 and delay by a delay line 17, to a band pass filter 15 which selects the chrominance signal and applies it to synchronized demodulator circuits 19R, 19G, 19B, and to a band-pass filter 14 which selects the amplitude-modulated index signal. The index signal passes to a demodulator circuit 20 to select the envelope of the index signal, a band-pass filter 21, amplitude limiting means 22, frequency multiplying means 23 to triple the index signal frequency and a phaseshifting circuit 24 to provide three carrier signals of differing phase for application to the respective demodulator circuits 19R, 19G, 19B. Colour difference signals are then obtained at terminals 18R, 18G, 18B, the luminance signal being obtained at terminal 18Y.

Title: Improvements in semiconductor devices
IPC: H01L29/87
Filed: 1960-08-10
Abstract: 880,216. Semiconductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 10, 1960 [Nov. 17, 1959], No. 27744/60. Class 37. [Also in Group XL (c)] One of the outer junctions of a PNPN diode is shunted by an Esaki diode which may be formed separately from or integral with the semiconductor body of the PNPN diode. A typical device (Fig. 2) including an integrally formed Esaki diode is made from an NPN germanium body by first diffusing arsenic from the vapour phase into its opposed surfaces for a period of 5 hours at 850‹ C. to form degenerate N+ zones, one of which is then removed by lapping. The body, in the form of a large sheet is later subdivided. Alternatively, the sheet may be subdivided prior to its exposure to arsenic vapour, in which case it is masked so that an N+ zone is formed in only one surface. An indium dot is next heated at 550 ‹ C in contact with the N+ zone for 15 minutes to form a P zone extending through the N+ zone to form a junction with the underlying N type material. Finally, a tin-gallium dot is alloyed to the N+ zone adjacent the indium dot in a short heating step to form a degenerate P+ zone on top of the N+ zone. The two dots are subsequently joined by a heavy conductor or preferably are arranged to touch or overlap (Fig. 9).

Abstract: 634,461. Gas turbine plant. NAPIER & SON, Ltd., D., and WYNNE, C. H. L. Oct. 20, 1947, No. 27987. [Class 110(iii)] In the control of a combustion chamber for gas turbines comprising spill-type burners, fuel is supplied to the .burners from a constant pressure source and that supply of fuel and the spill flow are simultaneously regulated in opposite senses in accordance with variations in the air-inlet pressure and in the same sense in accordance with variations in the airinlet temperature. The flow of fuel from a supply pipe A, Fig. 1, to the burner G. is determined by a metering orifice B<2> provided by a slot in a cylinder B<3> which' fits tightly on a cylinder B<1>. The pressure drop across the orifice is maintained constant under constant conditions by a device D. This comprises a fixed valve E and a valve-seating in a piston D<3> which is subjected to the inlet and outlet pressures of the metering device B and to the pressure of a spring D<2>. The fuel passes by the valve E to the pipe F. The spillflow from the burner is determined by a metering orifice K<5> provided by a triangular slot K<4>, in a cylinder K<3> where it is open between the adjacent ends of the cylinders K<1>, K2. The pressure drop across this orifice is controlled by a device J similar to the device D. Power control is effected by movement of a rod O which varies the width of the orifice K<5>. The cylinders B<3>, K<2> are moved together to vary both metering orifices by a temperature - responsive device Q<4> acting through levers Q<3>, Q and Q<1>. The spring loading on the pistons D<3>, J<3> are varied in opposite senses by movement of a rod R under the control of a device R<2> which is responsive to variations in the air-inlet pressure. A second orifice P, in parallel with the metering orifice K<5>, opens into the slot K<4> when the cylinder K<3> is in its extreme left position and provides a fine adjustment for the spillflow at no load. The spring-loading of the pistons D<3>, J<3> may be replaced by hydraulic loading by means of fuel from the spillflow pipe H which is passed through a pressure-regulating valve responsive to the air-inlet pressure.
