DEFINITION

Classification: 315/14

(under subclass 1) Subject matter wherein the cathode-ray tube is provided with a plurality of means for either concentrating, accelerating and/or de-accelerating the cathode-ray, and the system includes means for supplying electric current and/or potential to such means.

(1) Note. The concentrating, accelerating, and/or de-accelerating means may be electrostatic, electromagnetic, or both.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5+, for cathode-ray tube circuits wherein the ray passes through or in a hollow distributed parameter device, the ray being accelerated or decelerated while so passing, and especially subclasses 5.16+, 5.27, 5.28, and 5.41 where the ray passes through a plurality of such devices; and subclasses 5.34+ where structure is included for

concentrating the ray.

13.1, for cathode-ray tube systems wherein the cathode-ray tube is provided with means for forming a plurality of cath-ode-ray beams in the tube, each of the beams being provided with concentrating, accelerating, and/or de-accelerating means.

SEE OR SEARCH CLASS 313, Electric Lamp and Discharge Devices,

441+, for cathode-ray tube structures which have a plurality of electrodes between the cathode and the target (e.g., a plurality of accelerating and/or decelerating electrodes, and/or concentrating electrodes, and/or modulating electrodes).
