In addition, at step S15, an integer string bi (i=1 to (n−1)) and a real number C are used to calculate an initial value B01 (i=1 to n) of an adjustment parameter Bi (i=1 to n).

摘要： The invention provides a battery condition estimating method and a power system permitting to estimate aging level or discharge ability of a battery in high precision by reducing transient changes of response voltages caused by repetitive discharges. A recovery time after a discharge is prolonged with a number of times of discharge and a relationship between the number of times of discharge and the recovery time is approximated by using an exponential function in the battery condition estimating method of the invention. A discharge pattern as shown in FIG. 1 is formed by using the recovery time obtained from this approximation and substantially constant response voltage is obtained by discharging the battery in accordance to this discharge pattern. Then, impedance during a metastable condition is calculated from the measured response voltage and the discharge current and the aging level or the discharge ability of the battery is determined from the impedance.

摘要： The invention relates to a small-sized multiple-core optical connector having high reliability, which can be easily assembled and manufactured. A plurality of array guide grooves (22) are arrayed and formed on a flat substrate (21). The array pitch interval of the array guide grooves is roughly coincident with the outer diameter of bare optical fibers (4a), (4b). The first optical fiber tape (6a) and the second optical fiber tape (6b) are disposed at the rear end side of the flat substrate (21) so as to overlap each other, wherein the first bare optical fibers (4a) of the first optical fiber tape (6a) and the second bare optical fibers (4b) of the second optical fiber tape (6b) are alternately array-converted and accommodated in the array guide grooves (22). The bare optical fibers (4a), (4b) are pressed from the upside of the bare optical fibers (4a),(4b) at the tip end side of the array, and they are placed and fixed in the array guide grooves. A filter insertion groove (17) is formed in the direction crossing the corresponding array guide grooves (22) at an area where the array guide grooves (22) are formed, a filter (16) is inserted into the filter insertion groove (17), and the filter (16) is attached to each of the second bare optical fibers (4b) at the second optical fiber tape (6b) side.
