DEFINITION

Classification: 315/39

(under subclass 32) Subject matter having an electric discharge device load structurally combined with an electric wave transmission device or line having or acting as if it had distributed inductance or capacitance.

(1) Note. See (8) Note to subclass 32.

(2) Note. The transmission device or line may be a waveguide, a coaxial line or a parallel wire transmission line.

SEE OR SEARCH THIS CLASS, SUBCLASS:

3.5+, and 4+, for this subject matter where the discharge device includes means to focus or otherwise shape the electron stream into a beam. See subclasses 3.5+ where the

transmission line or device includes means to exhibit a wave component of a traveling wave, the velocity of which is reduced in comparison to the wave velocity in free space.

331, Oscillators,

5, 6+, 79+, 86+, 93, and 96+ for electrical oscillation systems wherein a space discharge device is combined with a distributed parameter impedance device.
