DEFINITION

Classification: 315/364

(under subclass 1) Subject matter which includes a cathode-ray tube including a cathode-ray beam source, cathode-ray deflection means operably connected with the cathode tube and an electrical circuit connected to the deflection means to deliver, when energized, voltage or current to the deflection means to move the cathode-ray beam from one position to another within the tube and methods corresponding to the above apparatus.

(1) Note. Included in this group of subclasses are subcombinations which include the deflection means and the electrical circuit to energize the deflection means when not elsewhere classified.

(2) Note. The electric circuit connected to the deflection means, instead of directly causing a cathode-ray to be deflected may, when acting in conjunction with another electrical force on a cathode-ray beam cause, by a change of current or potential, deflection of the cathode-ray beam.
