摘要： PROBLEM TO BE SOLVED: To provide a wire in which a conductor cannot be easily separated from an insulting coating film even if for example the wire is pulled by increasing the coherency between the conductor and the insulating coating film. SOLUTION: The wire has a prevention means for preventing the relative position misalignment between the conductor 2 and the insulating coating film 3 when a pull in the direction of the axial center operates on the wire 1. One embodiment of the prevention means is an irregularity 2a artificially formed on the surface of the conductor. Other embodiments are a chemical coating film 4 formed by providing an irregularity 4a on the surface of the conductor, and a cation electrodeposited coating film 5 formed on the surface of the chemical coating film 4.

摘要： PROBLEM TO BE SOLVED: To provide a rotor having no gap between an insertion hole in itself and a magnet, and to provide a method of a manufacturing the rotor.
SOLUTION: The method of manufacturing a rotor 1 comprises the first process of manufacturing a resin-covered magnet 2 for insertion which has sectional area larger than the sectional area of at least an insertion hole 12 by forming a cover layer 22 around the magnet 21, and the second process of inserting the resin-covered magnet 2 for insertion into the insertion hole 12, while shaving the periphery of the cover layer 22 for insertion with the edge part of the insertion hole 12. In the first process, a cover layer is formed by electrodeposition. This layer is such that the cover layer 22 is provided with a rib 23, extending in the direction of insertion and that a cut 12, to be engaged with the rib 23, is bored in the insertion hole 12.

摘要： PURPOSE:To provide a double layer plated steel sheet where excellent coating finish performance is obtained and a method for manufacturing the same. CONSTITUTION:A zinc plated layer as an lower layer is formed at least on one surface of a steel sheet to produce a zinc plated steel sheet and an iron-zinc alloy electroplated layer as an upper layer is formed on the zinc plated steel sheet to produce a double layer plated steel sheet. At this time, the iron-zinc alloy electroplated layer as the upper layer is formed under condition that zinc ion concentration in a plating bath is >=1.5g/l pH of the plating bath is 0.5-2.0, current density is 10-200A/dm , relative flow velocity is >=2m/s, and just after the upper layer plating is formed, the surface is forcibly washed. Consequently a double layer plated steel sheet where the coating weight of zinc oxide and zinc hydroxide existing in the upper layer plating and on the surface is >=100mg/m in terms of zinc is produced.
