DEFINITION

Classification: 315/39.63

(under subclass 39.51) Devices which are provided with a control electrode, an auxiliary anode, an auxiliary cathode or a secondary emitter electrode.

(1) Note. The secondary emitter electrode may be upon the same support as the primary cathode. The auxiliary electrode need not be formed so as to provide a portion of the distributed impedance structure.

(2) Note. This subclass includes either as originals or as cross-references substantially all magnetrons which are provided with more than two electrodes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

39.55, for magnetrons under subclass 39.51 which have an electrode designed for use in tuning or varying the reactance of the distributed impedance of the structure.

39.57, for devices under subclass 39.51 which are provided with an auxiliary cathode for use in tuning the distributed impedance structure.

miscellaneous discharge devices which are provided with a control electrode interposed in the discharge space between the cathode and the anode, subclass 306 for miscellaneous discharge devices having three or more electrodes (e.g., plural anodes or plural cathodes), and subclass 308 for miscellaneous discharge devices which are provided with a discharge control electrode.
