DEFINITION

Classification: 315/42

(under subclass 41) Subject matter, wherein the discharge device is provided with a plurality of anodes or a plurality of cathodes, and the inductive impedance is electrically connected between (1) at least two of such anodes, or (2) at least two of such cathodes.

39.51+, and 40, for discharge devices which have an electrode formed so as to function as an inductive impedance, or as a combined inductance and capacitance, see subclass 39.51 where the electrode is formed to provide distributed inductance and capacitance and an electromagnet is provided for subjecting the discharge space to a magnetic field. Subclasses 39.51+, 40 and 42 all include magnetrons, those in subclasses 39.51+ having an electrode formed to provide distributed inductance and capacitance (e.g., resonator), those in subclass 40 having an electrode formed to provide only an inductive impedance (a separate capacitor being used), and those in subclass 42 having both a separate inductor and capacitor. Subclass 40 also provides for the devices where the electrode

is formed to provide both distributed inductance and capacitance, but which are not designed to operate in a magnetic field.
