Abstract

Procedimiento y aparato imanador para establecer la pureza de color de tres haces electrónicos en tubos de rayos catódicos, caracterizado porque para establecer la pureza de los colores de tres cañones electrónicos en línea de un tubo de rayos catódicos, se disponen las fases de, colocar un material magnético adyacente a la parte del cuello del tubo de rayos catódicos, colocar alrededor de dicha parte del cuello por lo menos dos bucles conductores alargado, siguiendo una parte alargada de cada uno de los bucles conductores a lo largo de una parte de la periferia de la parte del cuello para crear regiones permanentes imanadas dentro del material magnético al acoplar corriente imanante a los bucles conductores alargados, determinar la cantidad de corrección de pureza de los colores necesaria, y alimentar corriente imanante de magnitudes y direcciones predeterminadas a los bucles conductores alargados para establecer la pureza del color de los tres cañones electrónicos en línea.
