    摘要: A self converging, widescreen color picture tube system includes a widescreen, in-line color picture tube having a funnel, an electron gun assembly (28) for three in-line electron beams located in a neck at one end of the picture tube, and a faceplate with a viewing screen at the other end. The picture tube has a wide aspect ratio. A self converging widescreen deflection yoke (40) for deflecting the electron beams in the wide aspect ratio picture tube includes horizontal and vertical deflection windings. The yoke (40) is located by an initial flare section of the funnel and positioned along the longitudinal axis of the picture tube to make the tube reference line and the yoke deflection plane substantially coincident. To achieve substantial horizontal astigmatism correction at the extremes of the major axis of the wide viewing screen, the horizontal deflection winding is constructed to have a generally pincushion-shaped horizontal deflection field over the effective length of the field. The field is modified from that required of the horizontal deflection field in a comparable self converging narrowscreen yoke. The modification is made in accordance with the differences in centerscreen slope angles and S-spacing.

    摘要: In a deflection yoke mounted on a cathode ray tube, a pair of silicon steel field harmonic enhancers are placed over rear portions of a horizontal deflection coil of a saddle coil type near an electron beam entrance region of the coils such that portions of the saddle coils are interposed between the field harmonic enhancers and a neck portion of the cathode ray tube. The field harmonic enhancers reduce horizontal coma error by making the horizontal deflection field in the rear portion of the saddle coils more pincushion shaped.

    摘要: A self converging deflection yoke includes saddle coils having tabs mounted on or, alternatively, spaces formed in the windings. The tabs or spaces are located intermediate a gun end and a screen end of the deflection yoke. The tabs or spaces correct misconvergence at, the 2:30, 4:30, 8:30 and 10:30 hour points of a crosshatch pattern.

    摘要: A deviator associated with an autoconvergent color image tube is modified so that it may be used in combination with a tube of the same type, but having an image screen of smaller size, the horizontal and/or vertical deviation center being displaced. According to the invention, a magnetic screen is placed across the magnetic field lines produced by the vertical and horizontal deviation coils whereby the deviation centers are displaced without any modification of the coils.
