Abstract

Mejoras en dispositivos electrónicos que comprenden dentro de una cubierta un aparato para producir un haz, medios para hacer girara el haz, y una pluralidad de blancos sobre los cuales puede incidir sucesivamente el haz de ser girado, caracterizado por el hecho de que los blancos están dispuestos en una pluralidad de hileras espaciadas a lo largo del eje de rotación del haz, consistiendo cada hilera en una pluralidad de elementos de blanco equidistantes del ápice de rotación y espaciados a lo largo de la periferia interna de la cubierta, y de que una fuente de potencial variable escalonado, está conectada a un elemento de desviación para el haz, siendo operable la referida fuente, un sincronismo con los medios para hacer girar el haz.Improvements in electronic devices that comprise within a cover an apparatus for producing a beam, means for making the beam rotate, and a plurality of targets on which the beam can successively impinge upon being rotated, characterized by the fact that the targets are arranged in a plurality of rows spaced along the axis of rotation of the beam, each row consisting of a plurality of target elements equidistant from the apex of rotation and spaced along the inner periphery of the cover, and that a source of stepped variable potential, it is connected to a deflection element for the beam, said source being operable, a synchronism with the means for rotating the beam.
