Abstract: A hydrogen generator having a reforming catalyst that causes hydrocarbon gas and steam to carry out a reforming reaction and reform into a hydrogen rich reformed gas, a reformer that is filled with said reforming catalyst and in which said reforming reaction is carried out, and a combustion chamber for combusting a fuel gas and obtaining reaction heat that is applied to said reforming reaction. At least the reforming region carrying out the reforming reaction is disposed inside the combustion chamber. A steam generator that introduces steam into the reformer is provided outside the combustion chamber.

Abstract: The present invention is to provide a high-speed image pickup apparatus, which can easily obtain the same image quality as that of the standard-speed image pickup by simply converting a high-speed video signal into a plurality of standard-speed video signals. Since the video camera system comprises a video camera for outputting a video signal by picking up an object at a high speed, a transmitting path for transmitting the video signal and a CCU for signal-processing the transmitted video signal, and divides the high-speed video signal into a plurality of standard-speed video signals directly or by providing a blank field as an additional period by the video camera, transmits the plurality of standard-speed video signals by the transmitting path, and arranges and outputs the plurality of standard-speed video signals at every unit period T by the CCU.

Abstract: In a color television camera of the type having a single image pickup tube with red, green and blue stripe filters for providing an electrical signal indicative of the image of an object, a luminance signal is separated by a low pass filter from the electrical signal, and a chrominance signal is also separated therefrom. A color difference signal is derived from the chrominance signal and is mixed with the luminance signal such that the polarity of the color difference signal is inverted relative to the luminance signal and a magnitude of the color difference signal is adjusted by a predetermined amount. The corrected luminance signal and a carrier chrominance signal are then combined to form a composite color video signal. A noise eliminating circuit is provided for improving the signal to noise ratio of the color difference signal used to correct the luminance signal.
