First Claim
Patent Images
1. A ceramic resistor heating plate comprising:
- a) at least one ceramic resistor heating body having front and back sides with conductive film on both front and back sides;
b) a protruding insulating region protruding outwardly from both the front and back sides, the region extending along at least two opposite margins bounding the conductive films; and
, c) a plurality of elongated, serpentine conductive fin plates, each having a height less than a corresponding dimension of the at least one ceramic resistor heating body and equal to a distance between the opposite margins of the conductive films bounded by the protruding insulating regions such that, one serpentine conductive film plate contacts the conductive film on each of the front and back sides of the ceramic resistor heating body.

Abstract
Disclosed is a ceramic-resistor heating plate for preventing corona discharge which is characterized in that an extruded insulating part is provided around the peripheral of the plate-shaped heating body. Therefore, the distance between the electrodes of the fin plates sandwiching the heating body can be increased and the problem of corona discharge can be prevented with reduced cost and enhanced safety.
