Disclosed is a method for forming a photocatalyst thin film, which is characterized in that a photocatalyst thin film containing a niobium-alkali metal complex oxide is formed by forming and then firing a layer containing a niobia nanosheet on the surface of a base containing an alkali metal.

An air purification system includes an internally hollow cylindrical casing made of a non-conducting material; an inner electrode arranged on an inner surface of the supporting member; an outer electrode arranged on an outer surface of the supporting member; a photocatalyst filter arranged on an outer surface of the outer electrode for purifying air inside a plasma generation zone; and a power source for supplying power of opposite polarities to each of the inner electrode and the outer electrode so as to generate plasma. The photocatalyst filter includes a filter element, and the filter element includes a porous titanium foil having a non-periodic spongy structure impregnated with anatase titanium dioxide particles as a photocatalyst.

Air purification system

An anode () and a cathode (), interposing a solid polymer film (), are disposed. While supplying purified water from a supply port () of an anode chamber (), wherein the anode () is disposed, and a supply port () of a cathode chamber (), wherein the cathode () is disposed, direct electric current is applied between the anode () and the cathode (). As a result, ozone-water is discharged from an outlet port () of the anode chamber (). In such an electrolysis cell (), a free-standing conductive diamond plate, formed by microwave plasma assisted CVD so as to have a thickness of 0.8 mm, is used as the anode (). The diamond plate is provided with holes, having a diameter of 1 mm and disposed such that a center distance therebetween becomes 2 mm. Therefore, the electrolysis cell () can stably produce ozone without causing exfoliation of the anode (), even when high voltage and large current are applied between the anode () and the cathode ().

In a mobile communication system, which has a plurality of radio network controllers and a number of radio base stations connected to each of the radio network controllers, for sending and receiving user data between a host network and mobile stations via the radio network controllers and radio base stations, a plurality of transmission paths that pass through one or more radio network controllers are set up between a base station, which sends and receives radio signals to and from a mobile station, and the host network. When data is being sent and received using one transmission path from the host network to a base station through a radio network controller, traffic conditions on this transmission path are monitored. When traffic has increased, the user data is dispersed by being passed through a plurality of transmission paths.
