    摘要: A bidirectional switching device includes a semiconductor multilayer structure made of a nitride semiconductor, a first ohmic electrode and a second ohmic electrode which are formed on the semiconductor multilayer structure, and a first gate electrode and a second gate electrode. The first gate electrode is covered with a first shield electrode having a potential substantially equal to that of the first ohmic electrode. The second gate electrode is covered with the second shield electrode having a potential substantially equal to that of the second ohmic electrode. An end of the first shield electrode is positioned between the first gate electrode and the second gate electrode, and an end of the second shield electrode is positioned between the second gate electrode and the first gate electrode.

    摘要: An object of the present invention is to provide a method for desalinating saltwater with a desalination device.The desalination device comprises inside a vessel, a breathable sheet, a water-repellent particle layer and a tank layer. The tank layer is positioned at the lower portion inside the vessel and the breathable sheet is interposed between the water-repellent particle layer and the tank layer. The breathable sheet comprises a through-hole, the water-repellent particle layer is composed of a plurality of water-repellent particles, and the surface of the respective water-repellent particles comprises a water-repellent film.The saltwater is desalted by a step of pouring saltwater into the vessel to dispose the saltwater on the surface of the water-repellent particle layer, a step of heating the saltwater to evaporate the saltwater into vapor; and a step of liquefying the vapor to obtain fresh water in the tank layer.
