    摘要: A thermoelectric conversion material is provided, in which only a desired crystal is selectively precipitated. An M x V 2 O 5 crystal is selectively precipitated in vanadium-based glass, wherein M is one metal element selected from the group consisting of iron, arsenic, antimony, bismuth, tungsten, molybdenum, manganese, nickel, copper, silver, an alkali metal and an alkaline earth metal, and 0
    The glass may comprise in mol% 10 Cu 2 O, 70 V 2 O 5 , 10 Fe 2 O 3 , 10 P 2 O 5 . The glass is converted to a glass-ceramic using microwave heating.

    摘要: The invention relates to a millimeter wave radar (1) that is used for the purpose of automatic operation or collision prevention of a vehicle, it is intended to solve the Problem that a side lobe (8) of a transmitted electromagnetic wave is reflected by surrounding bodies and the reflected wave is received, with the result that unnecessary bodies may also be detected. A layer higher in dielectric loss than a radome (2) or a magnetic loss layer (9) and a conductor layer (10) in a mesh form are embedded in a part of the inside surface of the radome (2), whereby it is possible to provide a millimeter wave radar (1) which is light in weight, excellent in weathering performance, inexpensive, and excellent in detection performance.
