DEFINITION

Classification: 315/39.53

(under subclass 39.51) Devices provided with means for coupling oscillating electrical energy to or extracting oscillatory electrical energy from the distributed impedance structure of the discharge devices.

(1) Note. Many of the patents in this subclass show the combination of a magnetron with a coupling loop or other coupling means for transferring energy to or from the distributed impedance structure (e.g., resonator) of the discharge device. Where the coupling means includes significant transmission line structure, such as a coaxial cable, a parallel wire transmission line or a waveguide, the patent is classified in subclass 39 and cross-referenced to this subclass.
