(JP8251957-A)      The generator includes two kinds of corrugated sheets or foils(10,11) laminated together and connected alternately at one end and the other to form several thermocouples connected in series in zigzag folds. The sheets are selected from combinations of alumel/chromel, iron/constantan and chromel/constantan and insulated from one another.    When hot junctions(12) are held at a high temp., a temp. gap along the thermal flux is generated in the sheets. Electromotive force at every thermocouple derived from the gap is summed up to a voltage level effective for outputting electric power through takeoff leads(13,14).    ADVANTAGE -   Has high efficiency.    (JP8254468-A)      The element has a number of thermo couples formed in a pair of metallic boards (10,11) which are set up in the zig-zag form with a laminated structure. A high temperature side junction part (12) and a low temperature side junction part (13) are formed in the metal boards. Two extraction electrodes (13,14) are provided on either end of metal boards. An outer barrier plate divides the high and low temperature sides of the junction part.    ADVANTAGE -   Increases electricity generation efficiency. Provides compact structure. Increases output voltage.
