Abstract: An infrared temperature-measurement probe, including: a probe housing; a reflector; and a reflector adjusting mechanism. The probe housing includes an inner wall, an outer wall, a cooling channel sandwiched between the inner wall and the outer wall, a chamber surrounded by the inner wall, and a light transmission hole communicating with the chamber. The reflector includes a mirror and a mirror frame. The reflector adjusting mechanism includes a motion controller, a drive coupling, and three control rods. The reflector and the three control rods are disposed in the chamber of the probe housing. The motion controller is disposed outside the chamber of the probe housing. The drive coupling is disposed between the motion controller and the three control rods, and the motion controller is adapted to move each of the three control rods via the drive coupling. The mirror is imbedded in and is supported by the mirror frame.

Abstract: A thermoelectric conversion material having excellent thermoelectric performance over a wide temperature range, and a thermoelectric conversion module providing excellent junctions between thermoelectric conversion materials and electrodes. An R-T-M-X-N thermoelectric conversion material has a structure expressed by the following formula: RrTt-mMmXx-nNn (0?r?1, 3?t?m?5, 0?m?0.5, 10?x?15, 0?n?2), where R represents three or more elements selected from the group consisting of rare earth elements, alkali metal elements, alkaline-earth metal elements, group 4 elements, and group 13 elements, T represents at least one element selected from Fe and Co, M represents at least one element selected from the group consisting of Ru, Os, Rh, Ir, Ni, Pd, Pt, Cu, Ag, and Au, X represents at least one element selected from the group consisting of P, As, Sb, and Bi, and N represents at least one element selected from Se and Te.

Abstract: A thermal stress of electrode members (121 to 123) due to an operation temperature may be relaxed by thermal stress relaxation layers (141 to 144), and thus peeling of the electrode members (121 to 123) due to thermal stress at the operation temperature may be prevented in a satisfactory manner. Furthermore, diffusion of a constituent component of the thermoelectric conversion members (111 and 112) due to the operation temperature and the like may be prevented by diffusion prevention layers (151 to 154), and thus durability and stability of the thermoelectric conversion module (100) may be improved.
