DEFINITION

Classification: 315/56

(under subclass 32) Subject matter, wherein the load device is a space discharge device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

33, for portable, self-contained apparatus which includes a discharge device load.

34, for discharge devices combined with an antenna.

35, and indented subclasses, for plural discharge devices structurally combined with a circuit element.

39+, for other discharge devices which have structurally combined therewith a transmission line of the distributed parameter type (e.g., waveguide, coaxial cable, etc).

39.51, for discharge devices which have an electrode formed so as to provide both inductive and capacitive impedance (e.g., resonator) and which are provided with an electromagnet for subjecting the discharge space to a magnetic field. 40, for discharge devices having an electrode formed as an inductive impedance or formed to provide both inductance and capacitance (e.g., a resonator).

41, and indented subclasses, for discharge devices combined with an inductive impedance connected between two or more electrodes of the discharge device.

46, and indented subclasses, for discharge device combined with a filament, heater, or resistance in shunt with the discharge electrodes.

49, for discharge devices combined with an electric heater or filament in electrical series with the discharge electrodes.

50, for discharge devices combined with temperature modifying means, the temperature modifying means being either designed to function as a circuit element or combined with the circuit element.

51, and indented subclasses, for discharge devices combined with plural circuit elements.

55, for discharge devices combined with an electric current generator or piezoelectric device.
