Abstract

Perfeccionamientos introducidos en una unidad de deflexión para un tubo de rayos catódicos, que comprende una armadura que está destinada a ser montada alrededor del cuello de un tubo de rayos catódicos, un sistema de bobinas consistente en un conjunto de bobinas de deflexión horizontal y un conjunto de bobinas de deflexión vertical que están soportadas por la armadura, y un anillo magnético de alta permeabilidad que rodea la parte activa del sistema de bobinas, comprendiendo la armadura medios de ajuste para desplazar relativamente el anillo magnético con respecto a las bobinas de deflexión al menos en una dirección perpendicular al eje geométrico de la unidad de deflexión, y medios para fijar el anillo magnético en la dirección axial, caracterizados porque en su lado que ha de estar enfrentado con la pantalla del tubo de rayos catódicos el anillo magnético está dispuesto en forma desplazable entre un miembro elástico y una superficie de aplicación ajustable situada diametralmente en oposición.
