Production manner null of denture attachment magnet

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a denture attachment which can improve productivity and production yield and can increase magnetic attracting force by securing a stable non-magnetic area. ;SOLUTION: In forming a non-magnetic seal ring part 17 of a seal plate 18 of this denture attachment magnet structure 1 to be attracted to a keeper attached at the root part by magnetic attracting force, Ni, Mn, or Ni-Mn alloy film is formed on the circumference side of the seal plate 18, and after that, it is alloyed by thermal diffusion and the non-magnetic seal ring part 17 is formed. Then the real plate 18 is brought into contact with a yoke 12 and the magnet 11, and the contact part of the yoke 12 and the seal plate 18 is connected.;COPYRIGHT: (C)1998,JPO
