Abstract

L'invention concerne une unité de commande de convergence destinée à un tube à rayons cathodiques du type à masque. Plusieurs paires d'aimants en anneau, réalisés en matière plastique magnétique, peuvent tourner autour du col d'un tube à rayons cathodiques. Les paires d'aimants peuvent tourner ensemble dans la même direction ou dans des sens opposés. Pour faciliter cette dernière rotation, une denture est formée directement sur les aimants. L'invention s'applique notamment aux tubes de télévision en couleurs.Provided is a convergence control unit for a mask type cathode ray tube. Several pairs of ring magnets, made of magnetic plastic, can rotate around the neck of a cathode ray tube. Pairs of magnets can rotate together in the same direction or in opposite directions. To facilitate this last rotation, a toothing is formed directly on the magnets. The invention applies in particular to color television tubes.
