摘要： A piezoelectric/electrostrictive device is formed with a connecting plate, a diaphragm, and a substrate which are mutually joined. A joining direction of the connecting plate with the substrate and a joining direction of the connecting plate with the diaphragm are mutually intersected to form a cross. The diaphragm is straddled between the connecting plate and the substrate. A piezoelectric element is arranged on a surface of the diaphragm, and the diaphragm is convexly curved in a direction perpendicular to the two directions forming the cross. The piezoelectric/electrostrictive device is an element for converting electrical energy into mechanical energy such as a mechanical displacement, force or vibrations. Conversely, the piezoelectric/electrostrictive device may be employed to convert mechanical energy into electrical energy, as well as improve the operational characteristics thereof.

摘要： The present invention relates to a cross flow type cooling tower with which it is possible to prevent emission of white vapor in cold weather. In order to accomplish the above object, the cooling tower of the present invention is constructed of heat exchange units each of which having plates arranged vertically and parallel from each other so as to form passages therebetween, which are separated into wet air passages and switchable air passages capable of switching from dry air passages and wet air passages; a water bath divided into upper and lower baths by a partition plate with holes, the upper bath is provided with spray nozzles for spraying water into the switchable passages, the lower bath provided with spray nozzles for spraying water into the wet passages. When the weather is warm, hot water is supplied into the upper bath, and both the upper and lower baths are filled with water and cooling is performed in every passage. However, when the weather is cold, then the water is supplied to the lower bath, and only the wet passages are used for heat dissipation and the switchable passages are uses to produce dry air to prevent generation of white vapor by mixing the dry air with the moist air.
