摘要:
In a pre-replacement process, a replacement battery module is provided with a memory effect before being dispatched, by performing at least one of the process of performing a cyclic charge/discharge operation on the replacement battery module while limiting the width of SOC change to an intermediate range, and the process of setting an initial SOC and then letting the replacement battery module stand for a predetermined time in an environment of temperature above normal temperature. This pre-replacement process substantially eliminates the difference between the voltage characteristic of the replacement battery module yet to be used and the voltage characteristic of a battery module having a history of use, thereby achieving a uniform voltage characteristic of a battery pack as a whole.

A battery ECU includes a central processing unit (CPU). The CPU calculates plural deterioration degrees based on data input from a thermistor, an ammeter, and a voltmeter which detect state quantities of a nickel-hydrogen battery, and reads, from a memory, contribution degrees each of which corresponds to each of the calculated plural deterioration degrees. Then the CPU calculates a total deterioration degree of the nickel-hydrogen battery based on the deterioration degrees and the contribution degrees, calculates the contribution degrees based on the calculated total deterioration degree, and stores the contribution degrees in the memory.

Disclosed is a method for forming a water-repellent film on the surface of a transparent substrate (e.g., sheet glass). While the film on the coated substrate is dried, the temperature is controlled to fall between 15.degree. C. and 25.degree. C., the relative humidity is controlled to be 30% or preferably from 15% to 20%, and the speed of the air stream to be applied to the coated substrate is controlled to be 0.5 m/min or lower. The water-repellent film formed by the invention has a uniform thickness and good abrasion resistance.

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.

Disclosed is a dichroic crystal including at least one member selected from the group consisting of phtharocyanine, a phtharocyanine derivative, phtharocyanine with a central metal introduced therein, a phtharocyanine derivative with a central metal introduced therein, and iodine. It is precipitated when the iodine is added to a solution containing the member, and it includes the iodine in a form of I.sub.3.sup.- and I.sub.5.sup.- ions. It not only has a high dichroic property but also superb heat resistance and weatherability, so that it is applicable to suspended particles display devices used in severe environments.

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.
