    摘要: A herapathite has a capillary crystal form in which its iodine atoms are oriented in a major axis direction of the capillary crystal form. The herapathite obtained is expressed by a chemical formula, xC.sub.20 H.sub.24 N.sub.2 O.sub.2.yH.sub.2 SO.sub.4.zHI.sub.3, in which a ratio of a number of the sulfuric acid molecules (y) with respect to a number of the iodine atoms (3z), i.e., (y/3z), is less than 0.5. The production process includes a reaction step, a first separating step, a recrystallizing step and a second separating step. A solvent used in the recrystallizing step is at least one of water and alcohol. A mixing weight ratio of water with respect to alcohol of the solvent is more than 50/50 or less than 10/90. The herapathite does not degrade even after it is heated up to 130.degree. C., and it is applicable to an automobile light shielding glass which should show a high transparency when a voltage is applied thereto.

    摘要: During use of a secondary battery, a concentration change ratio estimating unit estimates a ratio of change in electrolytic solution concentration based on a charging/discharging current. According to the estimated ratio of change, a concentration estimated value calculating unit sequentially calculates an electrolytic solution concentration estimated value during the use of the secondary battery. Based on the estimated electrolytic solution concentration estimated value, a determining unit determines whether or not the electrolytic solution concentration is within a normal range. When the electrolytic solution concentration is outside the normal range, a charging/discharging condition modifying unit modifies a charging/discharging condition of the secondary battery to bring the electrolytic solution concentration back to the normal range, thus avoiding a tendency of overcharge or a tendency of overdischarge.
