Abstract
We, now, ought to correct disorders that were found in No.6, Vol.32, of our journal.
Three figures, in the thesis by T. Nonaka, A. Iijima and S. Sato (p313-318), should belong to the one by T. Nonaka, T. Watanabe, S. Sato and T. Shimada (p. 319-328), and the converse should also be available.
