Abstract

1505564 Cathode ray display tubes TEKTRONIX Inc 16 May 1975 [5 July 1974] 8492/77 Divided out of 1505563 Heading H1D A horizontal deflection system for a dual electron beam apparatus comprises side-by-side pairs 40, 41 of horizontal deflection plates, each pair including an inner and outer plate 40alpha, 40b and 41a, 41b, the axis of symmetry 44, 45 of each pair converging towards each other, a support structure including insulating legs 134, 135, an isolation shield structure including an intergun isolation shield 80 between the deflection plate pairs and supported by the structure, and inner and outer shields 82, 84, 85 carried by the structure and disposed adjacent the exit of the deflection plates for correcting keystone distortion. The remaining disclosure corresponds generally to that of the parent Specification.
