DEFINITION

Classification: 315/4

(under subclass 3) Subject matter wherein the circuit element structurally combined with the cathode-ray tube is an inductor or a structure formed so as to act as if it possessed inductance with or without capacitance.

(1) Note. The inductive circuit structure may be a waveguide, a coaxial line, a hollow resonator, or a parallel wire transmission line or any other structure having or acting as if it had inductance or inductance and capacitance.

SEE OR SEARCH THIS CLASS, SUBCLASS:

39+, for other discharge devices which have structurally combined therewith a waveguide, coaxial cable, or other transmission line having distributed inductance and capacitance.

39.51+, for magnetrons which have an electrode with a portion formed to provide both distributed inductance and capacitance and a magnetic means for influencing the space discharge.

40, for other discharge devices having an electrode formed as an inductor or as a structure having inductive impedance.

62, and the subclasses specified in the notes to the definition of that subclass, for other discharge devices which are structurally combined with an inductive impedance. SEE OR SEARCH CLASS

219+, for electric resonators of the distributed parameter type, per se, and subclasses 236+ for other transmission line structure having distributed inductance and capacitance such as waveguides, coaxial cables, etc.
