Abstract

Un método para fabricar una unidad de desviación para un tubo de presentación de televisión en color del tipo que tiene una parte de cuello que contiene medios para generar una pluralidad de haces de electrones y una parte de cono con una pantalla de presentación alejada de dicha parte de cuello, y que tiene además un imán de pureza de color preajustado, comprendiendo dicha unidad de desviación bobinas de desviación de línea y campo y un núcleo magnético que coopera con dichas bobinas de desviación, caracterizado porque las bobinas de desviación y el núcleo magnético están colocados alrededor de la parte de la transición cuello-cono del tubo de presentación en color de tal manera que las bobinas de desviación se apliquen o sustancialmente se apliquen al tubo, después de los cual el tubo es ajustado de modo que sea puro de color, excitando dichas bobinas de desviación y dicho tubo de presentación y moviendo el núcleo magnético a lo largo del eje longitudinal del tubo, después de lo cual, sise desea, el núcleo magnético es movido de manera conocida en un plano perpendicular al eje del tubo, de modo que se eliminen los errores dinámicos de convergencia y el núcleo magnético y las bobinas son entonces asegurados juntos.
