    摘要: A deflection yoke for a color cathode ray tube includes a saddle shaped vertical deflection coil and a saddle shaped horizontal deflection coil. The horizontal deflection coil includes winding turns forming a pair of side portions having a winding window therebetween extending free of conductor wires. Each of the side portions has first and second winding spaces. The first winding space forms an aperture occupying an angular range between 30 and 45 degrees and having a length dimension greater than one half a length dimension of the window. A corner portion of the second winding space is disposed in a Z-axis coordinate selected in a range between a Z-axis coordinate of an end of the window, close to the electron gun of the tube, and a Z-axis coordinate, closer to the screen of the tube. The length of the range is approximately 10 % of a length of the window. Correction of convergence error, horizontal coma error, coma parabola error and trapezium error is obtained without using field shapers such as shunts or magnets.

    摘要: A video display deflection apparatus includes a vertical deflection coil. A separator is used for mounting the vertical deflection coil thereon. The separator has a funnel shaped first part conforming to a shape of a neck of the cathode ray tube and a second part forming a front portion of the separator close to the screen. A degree of flare of the first and second parts is substantially different. A saddle shaped, horizontal deflection coil (3) is mounted on the separator (2) for producing a deflection field to scan the electron beam along a horizontal axis of the display screen (9). The horizontal deflection coil includes a plurality of winding turns forming a pair of side portions, a rear end turn portion (19), close to an electron gun of the tube and a front end turn portion (29), close to the screen (9). At least a portion of the front end turn portion, in a radial angular position ranging between 0 and 30 degrees, is supported on the second part of said separator away from the boundary. Consequently, an effective length of the horizontal deflection coil is extended in a direction of the screen to provide north-south raster distortion correction. A magnetically permeable core (5) cooperates with the deflection coils to form a deflection yoke free of permanent magnets upfront.

    摘要: Electromagnetic deflection unit for colour cathode-ray tubes, comprising a pair of horizontal deflection coils and a pair of vertical deflection coils, the saddle-shaped vertical deflection coils having a rear bundle on the electron-gun side and a front bundle located on the screen side, lateral conductor harnesses 120 connecting the two bundles so as to produce a main window in the intermediate region lying between these said bundles, the conductor harnesses being arranged so that, at the front end of the main window 18, on the screen side, the window 18 extends over a radial angular aperture Φ of greater than 38°.
    This arrangement of the conductors in the rear part of the window makes it possible to minimize the vertical convergence errors between the red and blue beams, so as to avoid the use of additional field shapers to correct the said errors.

    摘要: A deflection yoke for a cathode ray tube having a large, flat faceplate and a 4:3 aspect ratio includes a saddle-shaped vertical deflection coil. Most of the winding turns at a rear end portion are concentrated close to the beam entrance end of the coil. Both the position of the peak and the vertical deflection center of the vertical deflection field are shifted toward the gun entrance end with respect to the corresponding peak and deflection center of the horizontal deflection field. Consequently, North-South magnets are not required for reducing North-South pincushion distortion. Also, a much shortened yoke is obtained than if the peak were not shifted.
