A system is provided to recover unutilized energy as electric power in hydraulic turbine power generation. The system includes a heat storage tank, a pump for pumping water from the heat storage tank and to air conditioning loads, a first water feed pipe connected between an outlet of the storage pump and the air conditioning loads, and a second water feed pipe for returning the water discharged from the air-conditioning loads. A hydraulic turbine driven generator is provided on a lower portion of the second water feed pipe at such a position as to recover the potential energy of the water discharged from the air conditioning loads.
摘要:
A method of fabricating a nitride semiconductor includes the steps of forming a nitride semiconductor doped with a p-type impurity, treating the surface of the nitride semiconductor in an atmosphere containing active oxygen to remove carbon remaining on the surface and form an oxide film thereon, and activating the p-type impurity to turn the conductive type of the nitride semiconductor into a p-type. Since carbon remaining on the surface of the nitride semiconductor is removed and the oxide film is formed thereon, the surface of the nitride semiconductor is prevented from being deteriorated by the activating treatment and the rate of activating the p-type impurity is enhanced. As a result, it is possible to reduce the contact resistance of the nitride semiconductor with an electrode and, hence, the variation in characteristics of the nitride semiconductor.

The invention discloses a method for counting foreign matter particles in a vinyl chloride resin powder comprising the steps of: forming an aqueous dispersion of the resin particles in a vessel having a transparent bottom, allowing the particles to settle forming a layer together with the foreign matter particles and viewing the layer of the deposited particles through the transparent bottom of the vessel to count the foreign matter particles in the deposited layer. The invention also provides an apparatus system for automatically counting foreign matter particles which comprises a vessel having a transparent bottom, a feed means for the resin powder, a water supply means, a stirrer means to form an aqueous dispersion in the vessel, a viewing means such as a CCD camera for recording the bottom image of the deposited layer through the transparent bottom of the vessel, and a control means for bringing the various parts of the system into a sequential linkage motion.
