RESISTIVE UNIT FOR FAN'S ENGINE Russian patent published in 1994 - IPC

Abstract RU 2018987 C1

FIELD: engines of fans. SUBSTANCE: resistive unit has one plate made of semiconductor material with positive temperature coefficient. The plate has two side surfaces and many electrodes, disposed onto one of two side surfaces at least. As a result, many different values of resistance may be achieved from one plate, that permits to design small and compact construction of resistive unit. EFFECT: improved efficiency. 11 cl, 8 dwg
