.~ Three or more nonemissive electrodes (e.g., plural anodes)
DEFINITION
Classification: 313/303
(under subclass 293) Discharge devices which have a plurality of separate nonemissive electrodes (e.g., anodes) in addition to the interposed apertured or grid-like electrode.
(1) Note. In the discharge devices in this subclass which have a plurality of anodes, the apertured or grid-like electrode may be interposed in only one of the inter-electrode spaces (e.g., the device having a triode section and a diode section) or the apertured or grid-like electrode may be interposed in a plurality of the inter-electrode spaces.
(2) Note. This subclass includes discharge devices which have a cathode, an anode, an apertured or grid-like electrode interposed between the cathode and anode, and an electrode or shield (e.g., shield grid) disposed outside of the inter-electrode discharge space (e.g., having a shield grid which surrounds a cylindrical anode).
SEE OR SEARCH THIS CLASS, SUBCLASS:
5+, for plural unit discharge devices which have at least two anodes and a cathode for each anode, one or more of the inter-electrode spaces having an apertured or grid-like electrode therein.
245, for discharge devices which include significant supporting and/or spacing structure for a plurality of discharge electrodes which form a plurality of separate discharge spaces.
298, for this subject matter where the discharge device has a plurality of apertured or grid-like electrodes interposed between two other electrodes in superimposed relation with respect to each other.
301, where the discharge device has a plurality of apertured or grid-like electrodes, the discharge device having either an apertured or grid-like electrode in each inter-electrode space or a plurality of apertured or grid-like electrodes in one discharge space in nonsuperimposed relation.
302, for discharge devices provided with a plurality of cathodes and an apertured or grid-like electrode interposed in one of the discharge spaces.
306+, and the subclasses specified in the notes thereto for other discharge devices provided with a plurality of anodes.
