Filed: 2002-09-03
Abstract: <P>PROBLEM TO BE SOLVED: To prevent deterioration in reliability of set cells through early detection of cell block, corresponding to single battery having pin holes and cracks.  <P>SOLUTION: A means for detecting defective cells 12 determines a cell, having great internal resistance, when overcharging after an abnormal cell has been detected, that is, the difference in voltage change from the voltage change of normal cells, when overcharging is larger than the constant obtained from cell characteristics, as a leakage defective cell, and determines a cell, of which the internal resistance does not increase, when overcharging as a slightly short-circuited cell. The reason is that in leakage defective cells, the cell voltage is larger when charging, because internal resistance rises, while cell voltage is smaller, when discharging; and in a slightly short-circuited cell, because of its reduction in capacity, the cell voltage is smaller, when discharging but is not larger when charging.  <P>COPYRIGHT: (C)2003,JPO

In this way, the multi-pulse sequence can be adjusted from the front pulse side and the rear pulse side so that an overall consistency can be realized in the mark shape upon recording the mark. At the same time, when n≥4, the fall of the first pulse is synchronized with a basic clock, and the fall of the second pulse and the rest of the pulses except for the last pulse are also synchronized with the basic clock by irradiating the pulses at periods of 2.5T or 2T.
