A battery charging control unit which controls electric power and supplies it to a battery via a charger. The battery charging control unit includes: a charging capacity insufficiency detection unit, a charging capacity restoring determination unit, and a supplemental charging unit. The charging capacity insufficiency detection unit detects an insufficiency in charging capacity of the battery based on the previous charging condition of the battery. The charging capacity restoring determination unit determines if the insufficiency in charging capacity of the battery will be restored by carrying out a supplemental charging process on the battery. The supplemental charging unit carries out the supplemental charging process for the battery if the charging capacity insufficiency detection unit detects the insufficiency in charging capacity of the battery and the charging capacity restoring determination unit determines that the insufficiency in charging capacity of the battery will be restored by the supplemental charging process.

Battery charging control unit and method for controlling battery charging

A slide surface construction is formed of an aggregate of Ni crystals having a face-centered cubic structure. The aggregate includes {220} oriented Ni crystals with their {220} planes (by Miller indices) oriented toward a slide surface and having a content S in a range represented by S&lt;25%. If the content of the {220 } oriented Ni crystals is set in such a range, a large number of quadrangular Ni crystals are precipitated in the slide surface, so that the oil retention and the initial conformability are improved by the Ni crystals. Thus, the slide surface construction exhibits an excellent seizure resistance.

Slide surface construction

A slide surface construction is formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes {222} oriented Fe crystals with their {222} planes by Miller indices oriented toward a slide surface. The content S of the {222} oriented Fe crystals is in a range represented by S.gtoreq.20%, preferably in a range represented by S.gtoreq.40%. The {222} oriented Fe crystals form a trigonal pyramid shape on the slide surface, which provides good oil retention for the slide surface construction. Thus, the slide surface construction exhibits an excellent seizure resistance.

Slide surface construction having orientation specific B.C.C. metal layer

A slide member includes a surface layer having a slide surface for sliding on a mating member, wherein the surface layer has metal crystals belonging to a cubic system with a crystal plane of high atomic density directed toward the slide surface and form the slide surface.

Slide member

A slide surface construction is formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes at least one of two types of metal crystals selected from the group consisting of (1) (h00) oriented metal crystals with their (h00) planes (by Miller indices) oriented toward a slide surface and having a content S in a range represented by S&lt;25%, and (2) (3hh0) oriented metal crystals with their (3hh0) planes (by Miller indices) oriented toward the slide surface and having a content S in a range represented by S&lt;25%. If both the types of the oriented Fe crystals are present, a large number of trigonal pyramid-shaped Fe crystals are precipitated in the slide surface, thereby providing improved oil retention and initial conformability. Thus, the slide surface construction exhibits an excellent seizure resistance.

A slide surface construction is formed of an aggregate of Fe crystals having a body-centered cubic structure. The aggregate includes (3hh0) oriented metal crystals with their (3hh0) planes (by Miller indices) oriented toward a slide surface. The content S of said (3hh0) oriented metal crystals is set in a range represented by S.gtoreq.40%. This makes it possible to provide a slide surface construction which has a predetermined hardness and an excellent wear resistance and ensures that the wearing of a mating member having a lower hardness can be suppressed.

A slide surface construction is formed of an aggregate of Ni crystals having a face-centered cubic structure. The aggregate includes {311} oriented Ni crystals with their {311} planes (by Miller indices) oriented toward a slide surface. The content S of the {311} oriented Ni crystals is set in a range represented by S.gtoreq.40%. The {311} oriented Ni crystals are of a quadrangular pyramid shape on the slide surface, and provide good oil retention for the slide surface construction. Thus, the slide surface construction exhibits an excellent seizure resistance.
