Abstract

Unité de déflexion pour tubes d'image de télévision en couleurs pourvue d'une bague magnétique déplaçable suivant deux directions perpendiculaires entre elles et perpendiculairement à l'axe du tube d'image à l'effet de compenser les erreurs de convergence, cette bague magnétique étant immobilisée, dans chaque sens de réglage, dans un support entre un organe élastique et une surface de butée réglable (de préférence de biais). Application aux récepteurs de télévision en couleur.Deflection unit for color television picture tubes provided with a magnetic ring movable in two directions perpendicular to each other and perpendicular to the axis of the picture tube in order to compensate for convergence errors, this magnetic ring being immobilized, in each direction of adjustment, in a support between an elastic member and an adjustable stop surface (preferably at an angle). Application to color television receivers.
