Abstract: A photovoltaic element includes at least an anode, a photoelectric conversion layer, an electron extraction layer and a cathode in this order, wherein the electron extraction layer contains a compound represented by formula (1): R—X?M+??(1) wherein R is selected from among hydrogen, and alkyl group which may have a substituent, X? is selected from among —COO?, —SO3?, —PO4H?, —PO42?, —O—SO3?, and M is selected from among alkali metals, alkaline-earth metals, and ammonium ion.

Abstract: Disclosed is an inductance part including a coiled conductor formed from a metal conductor, a magnetic body formed by pressure-molding a mixture of metal magnetic powder and bonding material in such a manner that the coiled conductor is embedded in the mixture, and a terminal derived from the coiled conductor. The coiled conductor is formed in a single layer with no insulating film on its surface. The metal magnetic powder of the magnetic body penetrates into the surface of the coiled conductor so as to make the filling factor of the metal magnetic powder in the magnetic body not less than 80% by volume.

Abstract: One object of the present invention is to provide a dissolved ozone decomposing apparatus which efficiently decomposes dissolved ozone in ozone water. The dissolved ozone decomposing apparatus comprises a case 2 and a first decomposing column 30 and a second decomposing column 40 in the case. The first decomposing column 30 comprises a flow pipe 31 in communication with a supply port 21, an adjustment plate 35 fixed in the flow pipe 31, a protection pipe 32 provided in the flow pipe 31 and made of a material transparent to ultraviolet rays, and a ultraviolet lamp 33 housed in the protection pipe 32, and when ozone water flows in the flow pipe 31, it strikes the adjustment plate 35 and stays in the pipe, so that the ozone water can be irradiated by light energy from the ultraviolet lamp 33 for decomposition of dissolved ozone in the ozone water.
