Abstract

Perfeccionamientos en dispositivos de corrección de linealidad y punteamiento lateral combinado, caracterizados porque comprenden un núcleo magnético que comprende una primera y una segunda partes de núcleo; una primera bobina devanada alrededor de la primera parte del núcleo y adaptada para acoplamiento a una bobina de deflexión horizontal; una segunda bobina devanada alrededor de la segunda parte del núcleo y adaptado para recibir una corriente de corrección cuya corriente de corrección comprende una componente de régimen de deflexión vertical; y medios magnéticos de polarización para proporcionar un flujo de polarización magnética a la primera parte del núcleo, para proporcionar corrección de linealidad a la corriente de exploración horizontal que fluye en la bobina de deflexión horizontal, configurándose la primera y la segunda partes del núcleo para establecer un trayecto de elevado reluctancia par flujo mutuo que enlaza la primera y la segunda bobinas con el fin de acoplar solamente una parte del flujo generado por la segunda bobina a la primera parte del núcleo, siendo las polaridades de la primera y la segunda bobinas las necesarias para permitir que la parte del flujo generada por la segunda bobina compensen los cambios indeseables durante la exploración vertical de la polarización magnética de la primera parte del núcleo.
