Title: Convergence deflection system for a color picture tube
IPC: H04N9/28
Filed: 1969-06-16
Abstract: 1,242,465. Cathode-ray tube circuits. SONY CORP. 16 June, 1969 [15 June, 1968], No. 30388/69. Heading H4T. In a single-gun three beam colour television cathode-ray tube in which the beams are focused on the tube screen by means of an electron lens through the optical centre of which all of the beams pass with two of the beams emerging from the lens along paths which are divergent to the optical axis whilst the third beam travels along this axis, convergence of the three beams at the screen is effected by means of electrostatic deflecting means acting on the two divergent beams the deflecting means being supplied with a fraction of the EHT operating D.C. voltage to provide for static convergence and with a parabolic wave of line scanning frequency modulated by a sawtooth wave, also at line scanning frequency, to provide for dynamic convergence. As shown in Fig. 1 the divergent beams B B  (Blue) and B R  (Red) emerging from lens L are converged with the axial beam B G  (Green) to pass through a common opening in an aperture grill (or shadow-mask) and then diverge to fall on respective colour dot or stripe elements S R  (Red), S G  (Green) and S B  (Blue) on the colour screen S by the application of the static and dynamic deflecting voltages to pairs of electrostatic deflecting plates P, Q and P<SP>1</SP>, Q<SP>1</SP> acting on the beams B B  and B R  respectively. For static convergence a voltage V Q  derived from a potential divider 30, 32 connected across the EHT supply V p  is supplied to the plates Q, Q<SP>1</SP> whilst the full voltage V p  (=V Q +200 to 300 V) is supplied to the plates P, P<SP>1</SP> (and also to the electrodes G3, G5 and to the screen S) the arrangement resulting in a static convergence voltage V c  adjustable by means of resistor 32 appearing between the plates P, P<SP>1</SP> and Q, Q<SP>1</SP>. For dynamic convergence a parabolic wave derived from a capacitor 27 in series with the line deflection coil 26 is supplied via an amplitude adjusting inductor 43 to one end of the primary 31a of a transformer 31 in which it is combined with a sawtooth wave at line frequency derived by the integrating effect of an inductor 35 and the resistance of a potentiometer 36 on line frequency pulse in a secondary winding 25C on the line transformer 25. A portion of the parabolic wave from a capacitance divider 38, 39 is fed to the centre tap of potentiometer 36 and the output from the slider 42 is fed to the other end of primary 31a. The dynamic convergence wave thus derived, the tilt of which is adjustable by potentiometer 42 and the magnitude by inductor 43, is then combined via the transformer 31 (which serves to isolate the EHT circuitry) with the static convergence voltage V c  to provide a composite convergence voltage V c  + e c . In a modification the adjustable resistor 32 is connected to the junction of resistor 30 and capacitor 44 (Fig. 3, not shown).

The contrast resolving power of an electronically produced image is increased at the expense of the detail resolving power by integrating the image elements over relatively large image elements, i.e. having, or being effectively equivalent to, an area with a maximum dimension between 5 mm. and 1 mm., e.g. 1 mm.<SP>2</SP>. The image may be of light, X- or γ-rays or corpuscular rays. As shown, an X-ray camera tube of the image orthicon type, is provided with a scintillation screen 11 and comprising scintillation bars (which may form part of the bulb) separated from one another by reflecting coatings 12 and of a length, e.g. 5 mm., providing optimum light yield with respect to X-ray quantum absorption, and a cross-section corresponding to the resolution required. A " light stop raster " to prevent dispersion may be fused into the end of the bulb beneath the screen 11. An electron lens system 9 provides variable demagnification of the electron image from photo-cathode 7 and focuses it on to a storage target 6 comprising a glass layer with mosaic storage electrodes 5 on the scanned side, the size of electrodes 5 also corresponding to the resolution required. Alternatively, the photo-cathode and lens 9 may be omitted, the X-ray image being focused directly on to a photo-conductive target provided with a mosaic storage electrode having large mosaic elements. Contrast may also be increased with reduced resolution by integrating electronically the video signal obtained by scanning a charge storage screen with normal elements, the signal associated with these elements being summated in a storage system so as to give an output equivalent to that which would be given by large elements.

Abstract: 932,624. Copying telegraphy. CREED & CO. Ltd. Sept. 8, 1961 [Sept. 9, 1960], No. 31171/60. Class 40 (3). Auxiliary photo-electric scanners 33-37, Fig. 1, examining the five lines 22-26 ahead of the line 20 being analysed and transmitted by the main scanner 16 produce signals in the presence of marks which, by means of a logic circuit, Fig. 2 (not shown), cause actuation of a selected one or more of five electromagnets, the electromagnets presetting a line advance mechanism (see below) whereby, at the completion of the scanning of the line by the main scanner, the scanning mechanism either advances to the next line, if a mark exists therein, or advances so as to skip, as appropriate in accordance with the marks detected, from one to five lines. The apparatus thus speeds the transmitting operation by skipping over blank lines. The logic circuit also causes the operation of a selected one or none of five relays and these are employed to cause the transmission to the receiver by pulse code or a combination of three frequencies, Fig. 4 (not shown), of a signal by means of which a mechanism identical with that at the transmitter is preset to cause the recorder to execute a similar line skipping motion. The invention is stated to be of application with flat-bed scanning apparatus, but is described only as applied to drum-type apparatus where a motor 6 drives the message drum 1 through gears 7, 8 and drives via gears 10, 11 a shaft 9 for advancing the scanning mechanism 14. Cam-operated switches 69, 112 and 130 for operating the line skipping mechanism and sending the signal from transmitter and receiver are driven from the drum shaft 4. The line advance mechanism, Fig. 3, comprises a member 75 which is pivoted at 76 so as to be displaceable by energization of an electromagnet 72. One part, 77, of the member carries toothed segment 78 which, through a gear train 79, 85, 86 including ratchet assembly 81-84, advances the scanning mechanism 14 by rotation of shaft 9. Another part, 87, allows movement to a predetermined extent from a rest stop 88 in order to determine the extent to which the scanning mechanism is advanced. For this purpose, the maximum movement corresponding to an advance of six lines is limited by a stop 110 and intermediate movements corresponding to advance through any number of lines between 0 and 5 are introduced by positioning an appropriate one of the members 90-94 in the path of the movement of end of part 87. The members 90-94 are carried by arms 95-99 which are spring-urged against stops 105-109 respectively, so that the members are normally out of the path of part 87, and a selected one is displaced into the path of part 87 by energization of an electromagnet 49, 52, 56, 60 or 64, as determined by the operation of the logic circuit.
