Abstract: The present invention separates radiation from an object by a polarization filter 3 into polarized light beams, causes one of the beams to enter a spectrum analyzer 7 through a first optical path, causes the other to enter the spectrum analyzer 7 through a second optical path, and measures the two-color ratio, while causes radiation of a blackbody 2 placed in a vacuum ultralow temperature thermostatic chamber 1 in a quasi-thermal equilibrium state at an ultralow temperature in vacuo to enter the polarization filter 3 through a third optical path, separates the radiation into polarized light beams, causes the beams to each enter the same optical paths as the respective optical paths for the radiation of the object, causes the beams to enter the spectrum analyzer 7, measures the two-color ratio, and accurately obtains the temperature of the object on the basis of these two two-color ratios.

Abstract: A radio wave measurement device enabling highly sensitive measurements of radio waves at an extremely low temperature is disclosed. The radio wave measurement device has a radiation-blocking filter through which a targeted radio wave is transmitted, a radio wave-transparent material to reflect a non-targeted electromagnetic wave included in radio waves, and a radio wave detector which are placed in a vacuum vessel, in which the radio waves are transmitted through the radiation-blocking filter, the non-targeted electromagnetic wave included in the radio waves is reflected toward the radiation-blocking filter by the radio wave-transparent material and collected as heat into the radiation-blocking filter, and the heat is exhausted out of the system, allowing the radio waves transmitted through the radio wave-transparent material to be measured with high sensitivity by the radio wave detector.

Abstract: A grid interconnection device includes a relay controller configured to control separation or interconnection of a relay; a receiver configured to receive, from a predetermined transmission path, power failure information containing at least local area information indicating an area in which a power failure occurs; a determination unit configured to determine an occurrence of a power failure in a power distribution system, when the power failure information includes local area information of an area to which the power distribution system belongs; and a detector configured to detect an islanding state. The detector increases detection sensitivity of the islanding state when the determination unit determines the power failure in the power distribution system. The relay controller performs separation control for the relay when the islanding state is detected by the detector.

Abstract: A plurality of distributed power generation systems are connected via the Internet to a managing apparatus in a managing company. A power company communicates with the managing apparatus via another line. At peak times of power consumption in the midsummer and so forth, the power company requests the managing company to supply the power. The managing company controls to remotely set generation capacity of the distributed generation systems at maximum so as to reverse surplus power therefrom to a power system. A normal power rate is discounted for a user of the distributed generation system for his/her cooperation with the power company. The managing company charges the power company based on the surplus electric energy supplied to the power company.

Abstract: Proton-exchange membrane fuel-cell power generating equipment includes a heat exchanger coupled to a process burner and, therethrough, to a fan. When water needs to be heated, such as during startup, the water is circulated through the heat exchanger and the process burner is operated (ignited) to heat the water. When the water needs to be cooled, such as when a hot water reserving tank is full, the water is circulated through the heat exchanger and the fan is operated, but the process burner is not operated, to cool the water. Water is circulated through part or all of a water system to prevent freezing while the system is stopped. Optionally, the process burner is operated to heat the circulated water. The heat exchanger and other heat exchangers in the system are arranged to efficiently recover heat from burners, a fuel-cell cooling system and exothermic processes.

Abstract: Corrosion of metals such as silver and copper by sulfur and chlorine containing entities are substantially prevented by surrounding these materials with a suitable polymeric structure. The structure should be a polymer containing a material such as copper or aluminum that reacts readily with corrosive gases. In one advantageous embodiment a polymer bag containing approximately 35 weight percent of dispersed, powdered copper is employed to enclose a metal containing structure such as a printed circuit board. Use of this expedient substantially reduces corrosion of the printed circuit board.
