    摘要: The invention provides a noncontact measuring system for electrical conductivity, which uses a microwave. In the measuring system for electrical conductivity, the microwave generated in a network analyzer (NA) 110 is guided to a surface of a silicon wafer (sample) 160 through a waveguide 130 and a sensor 140. The surface of the silicon wafer 160 is irradiated with the microwave, and the sensor 140 receives the reflected microwave. The electrical conductivity of the silicon wafer 160 is measured in such a manner that a computer (personal computer) 120 calculates the electrical conductivity from an amplitude ratio A and phase difference null to a reflected wave of the silicon wafer 160, which is determined with the network analyzer 110. The computer 120 performs not only the calculation of the measurement but also whole control of the measuring system such as positioning of the sample.

    摘要: A damper in which magnetic particles are difficult to sediment irrespective of the kind of a magnetic fluid is provided. A damper is constituted of a vessel in which the magnetic fluid is accommodated and a slider (piston). As the piston, one that is made of a laminated body of a paramagnetic substance and a non-magnetic substance is used. When thus constituted, the magnetic particles stick to the piston. Accordingly, whatever magnetic fluid is used, the particles do not sediment. The laminated body that is used as the piston has the non-magnetic substance at both ends thereof. When the laminated body is thus constituted, the magnetic particles sticks uniformly. When the laminated body has the magnetic substance at both ends, magnetic particles stick to both ends needle-like.

    摘要: [Problems] To provide a thermoelectric power generation system that has a relatively simple configuration, is not prone to failure, and is capable of efficiently generating power from temperature changes in the surrounding environment alone, even where there is no heat source.
    [SOLUTION] A thermoelectric power generation device 13 is arranged between a heat storage body 11 having a phase-change material 11b and a heat exchange body 12 whose heat dissipation rate and/or heat absorption rate is greater than that of the heat storage body 11. The thermoelectric power generation device 13 is configured to generate electricity from the temperature difference between the heat storage body 11 and the heat exchange body 12. The thermoelectric power generation device 13 is plate-shaped, and one surface may be in contact with the heat storage body 11 and the other surface may be in contact with the heat exchange body 12.

    摘要: A novel method for producing a porous carbon material which makes it possible to easily produce a porous carbon material having a desired shape. The method includes immersing a carbon-containing material having a desired shape and composed of a compound, alloy or non-equilibrium alloy containing carbon in a metal bath, the metal bath having a solidification point that is lower than a melting point of the carbon-containing material, the metal bath being controlled to a lower temperature than a minimum value of a liquidus temperature within a compositional fluctuation range extending from the carbon-containing material to carbon by decreasing the other non-carbon main components, to thereby selectively elute the other non-carbon main components into the metal bath while maintaining an external shape of the carbon-containing material to give a porous carbon material having microvoids.

    摘要: A method for producing a nano-composite metal member, by which a nano-composite metal member can be readily produced and the production cost can be reduced, and a method for joining phase-separated metal solids using the principle same as that of the former method are provided. A nano-composite metal member is obtained by bringing a solid metal body comprising a first component into contact with a solid metal material comprising a compound, an alloy or a non-equilibrium alloy that simultaneously contains a second component and a third component having a positive heat of mixing and a negative heat of mixing, respectively, relative to the first component, and then performing heat treatment at a predetermined temperature for a predetermined length of time, so as to cause interdiffusion between the first component and the third component.
