Abstract: PURPOSE:To obtain an electrode material of Fe-Cr battery which suppresses generation of hydrogen at the negative terminal during the charging and enhances a total energy efficiency of battery by utilizing a carbon property material having a particular pseudo graphite fine crystal structure. CONSTITUTION:A carbon property material, which provides pseudo graphite fine crystal structure where the <002> plane interval obtained from the wide range X-ray analysis is 3.70Angstrom  or less in average and orientation of graphite layer for fiber axis is 30 or more and provides a number of combined oxygen atoms at the carbon material surface which is 3% or more of the carbon stoms, is used as the electrode material. Fur example, a cloth obtained by spinning and clothing from the recovered cellulose fiber of 1.5 deniel is subjected to the ammonium chloride processing, followed by flame resistant processing under the nitrogen gas flow at 270 deg.C. Thereafter, a temperature rise rate per hour of 400 deg.C is iraised up to 850 deg.C. The cloth is held under such condition for 30min and thereafter is cooled in order to obtain a carbon fiber cloth in the thickness of 1.3mm.. The cloth is then subjected again to the heat processing of 1,600 deg.C in the inactive gas ambient and is cooled. Thereafter, the cloth is subjected to the heat processing for 13min at 850 deg.C under the inactive gas having partial pressure of oxygen of 200Torr and is then taken out from such processing. Thereby, a cloth H, where d002=3.67Angstrom , z>=50, O/C=10.2%, can be obtained.

Abstract: PURPOSE:To obtain sufficient time delay accuracy and to reduce the scale of hardware by adjusting sample times of received sensor signals of a sample holding (S/H) circuit by the beam forming(BF) circuit which puts received beams having specific directivity together. CONSTITUTION:When the received sensor signals themselves are high in frequency and the received signal band is narrow in the BF circuit, the sampling frequency of the signals decreases almost to the signal band width. Further, time quantization accuracy for accurately obtaining time delay is affected by the sampling frequency. For the purpose, a filter circuit 1 which limits the band of signals from a receiving sensor array and the S/H circuit 2 which samples its output are provided to process the signals, which are further multiplexed by a multiplexer circuit 3 and then converted by an A/D converter 4. Then the respective converted received sensor signals are beam-added by an adding circuit 5 to obtain the quantization accuracy with sufficient time delay for the BF.
