Abstract

Perfeccionamientos en yugos de deflexión con un imán para producir la sensibilidad de convergencia a la posición del yugo, del tipo de yugos de deflexión convergente pare ser utilizado con un cinescopio de televisión en color graángular, que tiene una pluralidad de haces dispuestos en una línea horizontal, cuyo yugo dispone de medios para producir campos de deflexión que tienen una desuniformidad por términio medio que no es nula para hacer converger prácticamente los haces electrónicos en todos los puntos sobre la trama, caracterizados porque se dispone una región alrededor del extremo de entrada del yugo en la cuál el promedio de desuniformidad del campo es prácticamente nulo para reducir el efecto de la posición del yugo con relación a los haces electrónicos.
