Abstract

Un dispositivo para la correccion de error de coma diferencial negativo en bobinas de desviacion exentas de convergencia. La bobina de desviacion encierra una porcion de un tubo de rayos catodicos incluyendo una porcion de cuello del tubo de rayos catodicos e incluye: un separador alrededor del cual se provee una bobina de desviacion horizontal para proporcionar un campo de desviacion magnético horizontal; un nucleo alrededor del cual se enrolla una bobina de desviacion magnético vertical, el nucleo rodea parcialmente el separador; y una cubierta posterior que fija la bobina de desviacion al tubo de rayos catodicos, la cubierta posterior se coloca alrededor del cuello del tubo de rayos catodicos y tiene una primer lado orientado hacia la direccion de la pantalla del tubo de rayos catodicos y que descansa contra un extremo posterior del separador. De conformidad con la presente invencion, las derivaciones arqueadas que de preferencia son en forma de "C" y tienen radios internos que quedan paralelos al cuello del tubo de rayos catodicos, se colocan en el primer lado de la cubierta posterior y se centran de preferencia en un primer eje del cuello del tubo de rayos catodicos y este eje de la pantalla del tubo de rayos catodicos. El uso de estas derivaciones en forma de "C" se encuentra que corrige el error de coma diferencial negativo introducido mediante la bobina de desviacion exenta de convergencia.
