摘要:
A complex crystal is composed of anion of triiodine and cation of a fused compound consisting essentially of at least one nitrogen atom and at least 3 aromatic fused rings. Since the complex crystal has such a stable structure, it shows excellent heat resistance and excellent moisture resisting property. Furthermore, the complex crystal has light-polarizing performance because of an arrangement of the molecular chain of iodine. Moreover, the complex crystal exhibits excellent polarization because of an interaction between the fused compound and iodine. Therefore, the complex crystal is suitable for use as light-adjusting particles of a light valve or a light-adjusting glass.

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.

A terminal assembling structure includes a terminal metal fitting having a tinning layer on a surface thereof, a connecting portion overlapped with the terminal metal fitting, and a fastening member fastening the terminal metal fitting and the connecting portion. An adhesion phenomenon of metal is generated between the terminal metal fitting and the connecting portion by the fastening of the terminal member.
