195.~ Resistance value varied by removing or adding material


DEFINITION

Classification: 338/195

(under subclass 68) Subject matter wherein a finished or completely manufactured resistor includes structure for removing or adding resistance material to or from the resistance element to change the resistance value of the resistor; or wherein the resistance element is peculiarly adapted for such removal on addition of material; or wherein the resistance element includes resistance or conducting material which may be removed or slit to alter the resistance value of the element.

(1) Note. The subject matter in this subclass includes finished or completed resistors, as opposed to those resistors to which material is added or subtracted in or as part of the manufacturing of the resistor.
