Abstract
Un aparato de exhibicion comprende un tubo de rayos catodicos a colores que tiene un envolvente al vacío, con un panel de placa frontal sellado a un extremo de un embudo que está cerrado en el otro extremo por un cuello. El panel de placa frontal tiene una pantalla luminiscente ubicada en una superficie interior del mismo. Una máscara de sombra está ubicada cerca a la pantalla. La máscara de sombra comprende una hoja de metal que tiene una porcion central y una porcion exterior con una pluralidalectrones está dispuesto dentro del cuello para generar y dirigir haces de electrones hacia la pantalla. Un yugo de deflexion está dispuesto alrededor del envolvente en la union del cuello y el embudo. El yugo desvía los haces a fin de explorar una trama a través de la pantalla. El aparato de exhibicion está mejorado sobre otros dispositivos anteriores, en que las aberturas en la porcion exterior de la máscara, en el lado que ve a la pantalla de la misma, tienen orificios que están alargados en la direccion de los haces de electrones incidentes, y que están desplazados con relacion a los orificios correspondientes, en el lado que ve al cañon de electrones de la máscara. Un método de hacer la máscara emplea fotograbado.
