Abstract: Left and right cup portions and a base portion are separated at a bust perimeter position. A border frame made of a resin of a necessary rigidity and flexibility is attached along a separation edge of the base portion. A joining portion is provided unitarily on the border frame. A joiner portion is provided on the cup portion. The cup portion and the base portion are detachably connected by a female-male interconnection of the joiner portion with the joining portion.

Abstract: A tape-like connecting device adapted to firmly connect a plurality of parts of a textile product in a detachable manner, and a women's clothing product with cups using the same are provided. Both left and right cup portions are connected to each other by the tape-like connecting device. The tape-like connecting device has tape members and a connector, while the base portions of the connector are formed with depressions. The front end portions of the tape members are sewn to the center front cloths and the front end portions of the under tape by way of the depression to each other. Further, the base end portions of the tape members are sewn to cup wire portions, whereby the tape-like connecting device fulfills a main role of connecting both cup portions to each other.

Abstract: Using a chrome plating bath containing organic sulfonic acid, plating is conducted by application of a pulse current to thereby form a crack-free lower chrome layer on a steel substrate. The lower chrome layer has a compressive residual stress of 100 MPa or more and a crystal grain size of from 9 nm to less than 16 nm. Subsequently, by application of a direct current, a cracked upper chrome layer is formed on the lower chrome layer, to thereby obtain a chrome plated part. The lower chrome layer imparts the chrome plated part with heat resistance and corrosion resistance, and the upper chrome layer imparts the chrome plated part with wear resistance and good sliding properties.
