摘要： PURPOSE:To enhance a generating efficiency by providing a return tube for returning Na condensed in second regions of a plurality of generating elements to first regions by a common pump, further coupling the first regions by hollow connecting tubes, and disposing the open ends of the connecting tubes in spaces inside the first regions. CONSTITUTION:Na condensed in second regions 151 of generating elements is returned to wicks 112 of first regions 150 by a common pump 107. In this case, a pumping force operating the Na is total sum of the discharge pressure of the pump 107 and capillary tube forces of wicks 112 of the regions 150. The capillary tube forces are operated only when the wicks 112 are not filled with the Na. Accordingly, since the capillary tube forces always operate in a direction of filling the wicks 112 with the Na, even if the Na is returned by the pump 107, the Na amounts of the elements are not exceeded and not insufficient.

摘要： PURPOSE:To make it possible to manufacture a thermoelectric element having high energy transducing efficiency, by including 1 or more atomic % of oxygen in a fused material in quickIy cooling the melt of Fe-Si group alloy. CONSTITUTION:Pure material or mixed material, in which iron, silicon and oxygen are main components, is fused, and the fused material, in which the iron and the silicon are the main component end 1 atomic % or more of oxygen is included, is obtained. The fused material is quickly cooled, and an amorphous thermoelectric material is formed. Thus a critical cooling speed required for obtaining the amorphous state of iron silicide can be decreased. Amorphous Fe-Si based alloy, whose manufacture has been difficult except a thin film in a micron order in a conventional method, can be manufactured in a large quantity at a high speed. At this manufacturing speed, an amorphous ribbon having a thickness of 100mum-1 mm and a width of 3-10 mm can be formed at a rate of 10-30 m/sec. The ribbon formed in this way is molded into a bulk state having a thickness of 3-10 mm. Or the ribbon is sintered at a crystallizing temperature (-1,000 deg.C) or less. Thus the thermoelectric element having high energy transducing efficiency can be manufactured in a large quantity at a relatively low cost.
