ABSTRACT:
A tapered resistor device which includes generally a tapered resistive film comprising a semiconducting material or other suitable material with a negative temperature coefficient of resistivity is provided. It is apparent with reference to the curves which show the variation of .DELTA.E that large energy savings are possible at the narrow end of the taper with relatively small concomitant degradation in the temperature profile of the region of interest. It is therefore seen that employing a material with a negative temperature coefficient of resistivity provides an improvement in reducing power usage according to the principles of the instant invention.
