    Abstract: PURPOSE: To provide a thermoelectric element performance evaluation method and a device, wherein a one-dimensional heat flow condition can be realized so as to accurately evaluate the performance of a thermoelectric element of gradient structure under a condition of large temperature difference. CONSTITUTION: A thermoelectric element arranged between a primary heat source 2 and a cooling source to measure a thermoelectromotive force or the like is surrounded with a heat shield 7, and an auxiliary heat source 3 is provided to heat the outside of the heat shield 7 from across so as to make the temperature distribution of the heat shield 7 nearly equal to a temperature distribution induced in the thermoelectric element due to a temperature difference between the primary heat source 2 and the cooling source. A temperature distribution around the thermoelectric element is set nearly equal to that of the element, whereby the thermoelectric element is kept under a condition of one-dimensional heat flow.

    Abstract: PROBLEM TO BE SOLVED: To provide a stress-testing method and a stress-testing apparatus for greatly improving the evaluation of a light material such as a compound material by allowing a stress state to be solved in a state of including the lamination structure of a shell-like specimen and end face treatment and obtaining the temperature dependency of the amount of permeation of helium. SOLUTION: A shell-like specimen 1 comprising a carbon-fiber reinforced resin-based compound material that is used for a thin shell structure is fixed to an apparatus body 11, and the pressure of a helium gas supplied to a pressure chamber 21 is allowed to operate on the recessed surface side of a dome section 2 in the shell-like specimen 1. The displacement in a top section 2a of the dome section 2 is detected by a laser displacement meter 12. The shell-like specimen 1 is cooled to an arbitrary temperature via a partition board 18 that is cooled by an extremely low-temperature fluid supplied to a cooling chamber 22. The amount of the helium gas through the shell-like specimen 1 is detected by a helium leakage detector 33 for sucking through a negative pressure chamber 30. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To avoid the breakdown of each part and improve thermoelectric conversion property and reliability by constituting the heat conductive part of a thermoelectric conversion module out of a metallic plate or a metallic layer coated with a ceramic layer. SOLUTION: Heat conducting parts 26H and 26L are constituted of a metallic plate 28 or a metallic layer coated with a ceramic layer 27, so as to materialize electric insulation or good heat conduction between metallic segments 15A and 15B of a thermoelectric covering element 10 and heat conductive parts 26H and 26L. For example, after boring a through screw hole or the like in the required place of the metallic plate 28, the whole surface is flame-coated with Al2 O3 which is high in heat conductivity into a thickness in the range 10μm-50μm to coat it with a ceramic layer 27. Then, the heat conducting part 26H on high temperature side and the heat conducting part 26L on the cooling side made that way are fixed by fixing screws 18 such as insulating ceramic, teflon, or the like, so as to set up a thermoelectric conversion module.
