DEFINITION

Classification: 315/372

(under subclass 364) Subject matter wherein the cathode-ray tube includes a cathode-ray beam source and a plurality of spaced targets to receive the cathode-ray beam under the control of the deflection means when the cathode-ray tube and its deflection means are energized.

(1) Note. The term "target" includes anodes, collectors, and electrodes.

(2) Note. Under this group, no fluorescent targets are included. For color fluorescent targets are include. For color fluorescent screens wherein phosphors emit various colors when energized, see subclass 375.
