Abstract:
An electron beam controller to be disposed in the neck of a color Braun tube, in which the four-pole and six-pole convergence magnets and the two-pole purity controller magnets constituting it are a flame-resistant resin magnet material free of halogens, consisting essentially of:(A) a non-halogen polyamide resin composition;(B) a metal oxide hydrate of aluminum or magnesium having a mean grain size, r, of 1 .mu.m<r<5 .mu.m and present in an amount sufficient to provide the resin material with flame retardancy but not so much that the resin material will easily glow;(C) at least one member selected from the group consisting of antimony trioxide and zinc borate present in an amount sufficient to provide the resin material with flame retardancy but not so much that the resin material will easily glow; and(D) 20% to 50% by volume of a magnetic material.
