  • Patent number: 6680566
    Abstract: There is now provided a television cathode ray tube having a faceplate, an electron gun means, and a glass funnel to configure the cathode ray tube as a wide-angle, shallow-depth, implosion-resistant television cathode ray tube. The glass funnel has a solder edge, a funnel throat, a parabolic area and a funnel body and the external contour between the solder edge and the parabolic area along a first section which is defined by the direction of the diagonal of the television glass funnel is essentially a steeply descending straight line, along a second section which is defined by the direction of the major axis of the television glass funnel, is essentially a flat descending straight line, which descends steeply in a curve in the area of the solder edge, and along a third section which is defined by the direction of the small axis of the television glass funnel, is essentially a steeply descending straight line.

  • Patent number: 6570316
    Abstract: The invention relates to a television tube having a screen and a flare. In accordance with the invention at least the front surface of the screen has the shape of a geometric rectangle or at least approximately said shape. The flare has a corresponding contour in the area where they are joined.

  • Patent number: 6353284
    Abstract: The glass funnel for a cathode ray tube includes a cylindrical funnel neck (2); a funnel body (4) having successive transverse cross-sections that change over from a substantially circular shape to a substantially rectangular shape with cross-sectional areas growing continuously in a direction moving away from the funnel neck and a parabolic region (3) arranged between the funnel neck and the funnel body and having respective connecting sections to the funnel neck and the funnel body having corresponding substantially circular cross-sections. The parabolic region (3) has at least one part with a substantially rectangular cross-section and the at least one part is located between the respective connecting sections to the funnel neck and the funnel body. When a cathode ray tube is made from the glass funnel the electron gun is located in the funnel neck and the deflecting coil is arranged around to the parabolic section so that it is substantially closer than in the prior art cathode ray tube.
