(under subclass 364) Subject matter wherein the deflection means is a pair of electrostatic plates and the electrical circuit, connected to the pair of plates, includes a space discharge device, the electrostatic plates when energized by
the circuit causes an electrostatic field which interacts with the beam to move the beam in a directing transverse to and simultaneously with the movement of the beam within the tube.
(1) Note. The term "space discharge device" includes diodes and tube type amplifiers wherein an electric current flows between two spaced electrodes in an envelope and the space is constituted by a gas, vapor, or a vacuum.
