Abstract
FIELD: TV equipment. SUBSTANCE: gear for static convergence of rays and adjustment of COLOR purity in COLOR kinescopes with coplaner arrangement of electron guns has magnetic system composed of pair of two-pole magnets 8 and 9, two pairs of six-pole ring magnets 2, 3 and 5, 6 which centers are located on axial line of neck of kinescope 11. Two-pole ring magnets 8 and 9 are intended for adjustment of color purity. Six-pole ring magnets 2, 3 and 5, 6 are meant for convergence of side rays with central ray. Six-pole ring magnets 2, 3 and 5, 6 are magnetized in asymmetry to their centers and each pair has zero magnetic field correspondingly in zone of second and central rays and in zone of central and first side rays. EFFECT: increased efficiency of adjustment of color purity. 1 cl, 4 dwg
