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

Устройство для статического сведения лучей и выставления чистоты цвета в цветных кинескопах с компланарным расположением прожекторов содержит магнитную систему из пары двухполюсных магнитов 8 и 9, две пары шестиполюсных кольцевых магнитов 2,3 и 5,6, центры которых расположены на осевой линии горловины кинескопа 11. Двухполюсные кольцевые магниты 8 и 9 предназначены для выставления чистоты цвета, шестиполюсные кольцевые магниты 2,3 и 5,6 для сведения боковых лучей с центральным лучем. Шестиполюсные кольцевые магниты 2,3 и 5,6 намагничены асимметрично их центров и каждая пара имеет нулевое магнитное поле соответственно в зоне второго и центрального лучей, и в зоне центрального и первого бокового лучей.

A device for static beam reduction and color purity setting in color picture tubes with coplanar arrangement of searchlights contains a magnetic system of a pair of bipolar magnets 8 and 9, two pairs of six-pole ring magnets 2,3 and 5,6, the centers of which are located on the centerline of the neck of the tube 11. Bipolar ring magnets 8 and 9 are designed to set the color purity, six-pole ring magnets 2,3 and 5,6 to reduce the side rays with a central beam. The six-pole ring magnets 2.3 and 5.6 are magnetized asymmetrically to their centers and each pair has a zero magnetic field, respectively, in the zone of the second and central rays, and in the zone of the central and first side rays.
