This invention provides a method for suitably using a method for collectively receiving at a high voltage and distributing at a low voltage in collective housing. In this method for collectively receiving at a high voltage and distributing at a low voltage to a plurality of users, a distribution control part for collectively receiving power and distributing the power at a low voltage includes a serverand a control devicefor controlling information on power consumed by the users. The control deviceand the server are connected via a network. The servergrasps a maximum current capacity necessary for each user, determines a contracted current depending on the grasped maximum current capacity, and distributes power to each user.

Method for collectively receiving at high voltage and distributing at low voltage, and collective housing using same

A system for reducing power without making users feel inconvenience and discomfort in collective housing or the like. The system includes a plurality of air conditioners and a central control unit connected with the air conditioners via a communication line. The central control unit controls the plurality of air conditioners to operate in time or alternately to prevent electric current concentration.

Power load control system

A method of making a semiconductor film on a substrate having a non-flat surface, by placing the substrate in a reaction chamber including at least a pair of discharge electrodes, an inlet of a reaction gas for producing a desired semiconductor film, and an outlet for reduced pressure, and performing a discharge in the presence of said reacrion gas for producing said semiconductor film, while arranging said non-flat surface of said substrate outside a plasma region formed between said discharge electrodes and further locating said non-flat surface substantially in a vertical direction with respect to electrode surfaces of said discharge electrodes, thereby semiconductor film being directly and uniformly deposited on said non-flat surface of said substrate, which is of worth in the production of, e.g., roofing tile-shaped photovoltaic devices.
