The tube 1 of FIG. 1 is intended for use with an external magnetic deflection yoke, such as the yok

Cathode Ray Tube | Russian patents
Use: in cathode ray tubes (CRT). The inventive droog design CRT comprises a rectangular bottom flask with an outer surface having a curvature along its minor and major axes, and katodolyuminestsiruyuschy screen (EC) on its inner surface, wherein at least in the central part of the bottom of the flask curvature along the minor axis at at least 10% more than the curvature along the major axis. Points on the outer surface near the ends of the major axis (X - X) lying at the edge FE in a first plane (P1), perpendicular to the central longitudinal axis (Z - Z) of the tube, the points on the outer surfaces near the ends of the minor axis (Y - Y) on the edge TBE lie in a second plane (P2), parallel droog design to the first plane, a point on the outer surface near the ends of the diagonals of the rectangular bottom flask TBE lie on the edge of the third plane (P3), parallel to the first plane, the first, second, third and fourth plane spaced from the plane (P), parallel to them and tangent to the central part of the bottom of the flask, in the following order: second, first and third planes. Ratio of the distances between planes P2 - P and P3 - P is greater than the ratio of the square of the size of the minor axis of CE to the square the size of its diagonal, but less than one, and the ratio between the planes P1 - P and P3 - P is greater than the ratio of the square of the size of the major axis of TBE to the square of its diagonal size, but less than unity. 12 ill.

FIG. 1 shows a rectangular color CRT tube 1 having droog design a glass envelope 2 which comprises a rectangular bottom panel 3 and a tubular neck flask 4 connected rastrubok 5. Panel 6 includes droog design bottom flask for observation and a peripheral flange or sidewall 7 which is sealingly attached 5 to funnel 8 by means of sintering of the glass. Rectangular trichrome katodolyuminestsiruyuschy screen 9 located at the inner bottom surface 6 of the flask. The screen is preferably ruled 9, wherein the phosphor lines extend substantially parallel droog design to the minor axis YY tube (perpendicular to the plane of FIG. 1). Alternatively, the screen may be a dot. Color selection electrode with multiple openings or shadow mask 10 is removably mounted on the bottom of the bulb 3 at a predetermined distance from the screen 9. Linear electron gun 11 is mounted in the center of the neck 4 to generate and direct three electron beams 12 along coplanar convergent paths through the mask 10 to screen 9. Alternatively, the electron gun may have a triangular shape (a delta-configuration).
The tube 1 of FIG. 1 is intended for use with an external magnetic deflection yoke, such as the yoke 13 with the vertical and horizontal magnetic flux act on the three beams 12 to scan the beams horizontally in the direction of the major axis (X-X) and vertically in the direction of the minor axis (YY) respectively, on a rectangular pattern on the screen droog design ninth
Concrete panel according to the cross sections of the minor axis (YY), the major axis (X-X) and diagonals shown in FIGS. 3, 4 and 5. The outer surface droog design of the panel 3 along the curved bottom flask major and minor axes, and along the minor axis of curvature greater than the curvature droog design along the major axis, at least in the central droog design part of the bottom 3 of the flask. For example, in the center of the bottom of the flask 6, the ratio of the radius of curvature of the outer surface contour along the major axis to the radius of curvature along the minor axis greater than 1.1 (or greater than 10% difference). Sagittal height of the point on the contour of the panel measured from the plane (P) which is perpendicular to the longitudinal axis ZZ of the tube and the center involved in the panel 3 to the other plane (for example, P1, P2 or P3) which are parallel
