A recording and reproducing apparatus for reproducing information recorded on a recording medium concurrently while recording the information, includes a compression section, a temporary storage section, a reproducing process section, and a storage section. The compression section reads the information recorded on the recording medium and compresses read information. The temporary storage section stores compressed information provided by the compression process. The reproducing process section decompresses the compressed information output thereto from the temporary storage section and reproduces decompressed information. The storage section stores the compressed information output thereto from the temporary storage section.

摘要:
In a fuel cell power generation system for use with a fuel gas which is prepared by desulfurizing a raw fuel material such as naphtha, LPG, town gas, or the like and then, processing it by steam reforming reaction and thus, consists mainly of hydrogen or a process of producing the fuel gas, the desulfurization of the raw fuel material is implemented using a copper/zinc desulfurizing agent. As a result of the desulfurization, the raw fuel material is desulfurized at a higher level and the deterioration of a steam reforming catalyst employed is prevented. Accordingly, steady long-run operation of the fuel cell will be ensured. Also, upon the steam reforming reaction, the S/C (the mole number of steam per one mole of carbon in a raw fuel material) is reduced and thus, the concentration of hydrogen in the fuel gas will be increased providing an improvement in the efficiency of power generation.

In a gas separation apparatus that separates carbon dioxide and water vapor from a first mixture gas containing a predetermined major component gas, carbon dioxide, and water vapor, the energy utilization efficiency thereof is improved. Also, by utilizing the function of this gas separation apparatus, a membrane reactor and a hydrogen production apparatus exhibiting high energy utilization efficiency are provided. The gas separation apparatus is constructed to include a first separation membrane 33 and a second separation membrane 34 that are made of different materials. When the first mixture gas is supplied at a temperature of 100° C. or higher, the first separation membrane 33 separates a second mixture gas containing carbon dioxide and water vapor that permeate through the first separation membrane by allowing carbon dioxide and water vapor to permeate selectively. When the second mixture gas is supplied, the second separation membrane 34 separates water vapor that permeates through the second separation membrane 34 by allowing water vapor to permeate selectively.
