    摘要： A Group III nitride-based compound semiconductor light-emitting device having a quantum well structure, includes a well layer, a first layer formed on one surface of the well layer, a second layer formed on the other surface of the well layer, a first region provided in the vicinity of the interface between the first layer and the well layer, and a second region provided in the vicinity of the interface between the second layer and the well layer. A composition of the first and second regions gradually changes such that the lattice constants of the first and second layers approach the lattice constant of the well layer as a position approaches said well layer.

    摘要： A slide surface construction is formed of an aggregate of metal crystals. The area rate A of hexagonal pyramid-shaped metal crystals in a slide surface of the slide surface construction is in a range of A.gtoreq.40%, and the Co (cobalt) content in the aggregate is in a range of Co.gtoreq.13% by weight. The metal crystals are preferably Fe (ferrous) crystals. The slide surface takes on an intricate aspect due to the existing of a large number of hexagonal pyramid-shaped metal crystals and hence, has a good oil retention. In addition, the wearing of the hexagonal pyramid-shaped metal crystals is inhibited due to an increase in hardness resulting from the incorporation of Co and therefore, the oil retention is maintained. Thus, the slide surface construction exhibits an excellent seizure resistance.
