Abstract

Perfeccionamientos en los circuitos para el mando o maniobra de la deflexión vertical en los receptores televisores, especialmente los dotados de cinescopio de gran ángulo, caracterizados porque comprenden conexiones de contrareacción que tienen el objeto de deformar la forma de onda de la tensión de deflexión de dientes de sierra generada por el correspondiente generador sincronizado, antes de enviarla al amplificador de la deflexión, ejecutándose dicha contra-reacción mediante maniobra de la corriente de modo que reduzca además la influencia sobre la amplitud de la deflexión de las variaciones de la resistencia ohmica de las bobinas de deflexión, debidas a su recalentamiento durante el funcionamiento.
