Abstract: An improved cct. for obtaining a parabolical waveform signal, which can be used in deflection cct. of a TV, is disclosed. the bridge cct. (14) connected to the conventional saw-tooth waveform generator(10) is modified. First diodes(16,17) are connected in parallel with the second diode(24) and the variable resistor. Thus, parabolical waveform having required slope is obtained by the improved cct. First and second diodes had a different voltage barrier height each other.

Abstract: A large screen, wide deflection angle color picture tube(20) utilizes three coplanar electron beams(B,G,R). Convergence of horizontal lines on the picture tube viewing screen is accomplished by positioning a deflection yoke exihibiting particular astigmatism characteristics relative to the electron beams of the picture tube. Convergence of vertical lines is accomplished by energizing quadrupole magnetic field producing windings disposed in the picture tube neck at a vertical scanning rate.

Abstract: A color television display system is described which requires no dynamic convergence apparatus for small and medium size screen color picture tubes and which requires relatively simple dynamic convergence apparatus for large screen color picture tubes. The color picture tube includes an electron gun assembly for producing three adjacent horizontal in-line coplanar beams. The electron gun assembly includes a common three-aperture beam forming electrode for establishing precise alignment of the beams. The beams are substantially converged at all points in the scanned raster as they are deflected by a deflection yoke providing negative horizontal isotropic astigmatism and positive vertical isotropic astigmatism. The gun assembly includes magnetic shield members disposed around the two outside beam paths to shield those beams from a portion of the deflection field so that the rasters scanned by the three beams are of the same size. In addition, the color picture tube includes a faceplate having repeating groups of three different color phosphor strips and an aperture mask including a plurality of elongated slit apertures disposed adjacent the phosphor strips to enhance the light output from the picture tube.

Abstract: A deflection yoke for a television picture tube utilizing coplanar horizontal in-line electron guns includes vertical and horizontal coil windings selected for producing positive vertical isotropic astigmatism and negative horizontal isotropic astigmatism which underconverges the electron beams along the vertical deflection axis such that the beams are substantially converged at all points on a scanned raster of the picture tube. The desired convergence characteristics are achieved by winding the vertical and horizontal coil conductors such that the conductor distribution in each quadrant of a cross-section of the yoke is least in a region between 25* and 45* measured from the vertical deflection axis of the yoke.
