DEFINITION

Classification: 315/53

(under subclass 52) Subject matter, wherein one of the impedance elements is of a diverse type with respect to another of the impedance elements.

(1) Note. Impedance elements differing only in size, value,

or in the manner of connection to the load device are not considered to be of diverse types. Examples of impedance elements considered to be of diverse types with respect to each other are resistances, condensers and inductances.

SEE OR SEARCH THIS CLASS, SUBCLASS:

44, where there is an inductance and a condenser structurally combined with a discharge control discharge device, the inductance and the impedance each being connected between the control electrode and another electrode of the discharge device.

45, where one of the impedances is an inductance which is electrically connected between two electrodes of a discharge device load.
