摘要： A dental magnetic attachment which has a superior magnetic attractive force with a small nonmagnetic welded part and a flat welded surface to be polished. The dental magnetic attachment including a magnet, a yoke with a pit to hold the magnet, a sealing disk placed on the opening of the pit to cover the magnet and a nonmagnetic welded part between the yoke and the disk. The yoke and the disk are made from soft magnetic material. The nonmagnetic welded part, which joins the yoke and the disk, is formed by welding the yoke, the sealing disk, the sealing ring made from nonmagnetic austenitic stainless steel and a Ni coat between the sealing disk and the sealing ring together. Here, it is preferably that there remains a part of the nonmagnetic sealing ring. The welded surface of the dental magnetic attachment is polished to be flat.

摘要： A process for the preparation of disubstituted adamantine derivatives characterized by the factor that the aromatic receptors can be a series of halide anisole, phenol, toluene, naphthalene, thiophene, or furan and their substituted derivatives. The synthesized disubstituted adamantine derivatives were subsequently converted into a new class of synthetic retinoids of pharmaceutical importance.
