摘要： Method of manufacturing a metal gasket including a base plate having at least fluid passage holes and circular beads surrounding the fluid passage holes, the base plate being formed by providing a rubber coating layer on a surface of a metal plate with a base coat and an adhesive interposed therebetween. A metal plate having low-temperature age-hardening characteristics is used as the metal plate of the base plate. After the base coat is applied to the metal plate and dried at a temperature lower than a low aging temperature of the metal plate, press-working of the circular beads is performed on the metal plate. Thereafter, the metal plate is age-hardened while burning the base coat at the low aging temperature of the metal plate. A metal gasket having excellent durability and circular beads which are hardly broken even when crushed, is obtained.

摘要： There is provided a rare-earth permanent magnet optimized to an IPM type motor for a car, capable of improving corrosion resistance, abrasion resistance, and impact resistance. The rare-earth permanent magnet 16 is configured by forming an electroplated Ni coating film 21, of which thickness is 15 μm or more and 30 μm or less and of which shape is a columnar crystal structure, on a surface of a R—Fe—B system permanent magnet (R is a rare-earth element) 22. The electroplated Ni coating film 21 has a high hardness region, where the Vickers hardness is 300 or more and 600 or less, and a low hardness region, where the Vickers hardness is 150 or more and 300 or less. The rare-earth permanent magnet 16 is used in a state where the rare-earth permanent magnet 16 is inserted into a slot of a yoke in a rotor of an IPM type motor for a car.
