An object of the invention is to provide a power supply controller for stopping an output of a power supply portion without adding a new circuit in the combined electronic equipment, and dispensing with ONOFF operation of a power supply each time for every electronic equipment. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. The methods can involve uniformly cold stretching the films by stretching the films to a draw of about one hundred and eighty percent, or less, of the films’ original length. An intensity of the light is based on the power level associated with the output signal. A feature identifying unit checks a decoded feature obtained as a result of decoding the feature stream against a search key from a user for a match so that a video content requested by the user is retrieved.
