  • Cathode ray tube with flexible mount for deflection unit
    Patent number: 5804913
    Abstract: A cathode ray tube (1) including an electron gun (6) for generating at least one electron beam and a deflection unit for deflecting the electron beam(s) across a display screen. The deflection unit (11) includes a first system (21) and a second system (22, 32) of saddle-shaped deflection coils. Which are interconnected via connecting pieces (41, 51, 63, 64) which are flexibly arranged with respect to each other.

  • Cathode ray tube with temperature compensated deflection unit
    Patent number: 5714834
    Abstract: A cathode ray tube is provided with a deflection unit. The yoke is secured to a flange of a coil holder by means of connecting elements. These connecting elements are flexible in the radial direction so that differences in thermal expansion between the yoke and the rest of the deflection unit are compensated in a flexible manner. By virtue thereof, movement of the yoke relative to the coils, which leads to an irreversible change of the deflection fields, is precluded or is at least less likely.
