摘要：The heater includes a paper or plastic substrate on which is printed a semi-conductor pattern (typically a colloidal graphite ink) having (a) a pair of longitudinalstripes extending parallel to and spaced apart from each other and (b) a plurality ofidentical bars spaced apart from each other and extending between and electricallyconnected to the stripes. A metallic conductor (typically copper stripping) overlies eachof the longitudinal stripes in face-to-face engagement therewith, and the conductors areheld in tight engagement with the stripes by a sealing layer that overlies the metallicconductors and is sealed, at opposite sides of the semi-conductor stripe associated withthe particular metallic conductor, to portions of the substrate that are free from theprinted semi-conductor pattern.
