Abstract

PURPOSE:To reduce crystal grains through which signal current should be passed and to apply image/acoustic signal current surely without a phase difference by providing the titled winding with crystal construction extended like a fiber in the longitudinal direction. CONSTITUTION:At least one kind of metal out of Ag, Cr and Zr is contained in Cu. The oxygen content is <=300ppm and the conductivity is >=90% IACS. The orientated crystal structure is maintained also after enamel glazing. If the Ag content is <0.03%, the maintaining effect of the fiber-like construction is reduced, and when the Ag content exceeds 0.3%, said effect reaches almost saturation and further improvement can not be expected. When the Cr content is <0.01%, the effect is reduced, and if the Cr content exceeds 0.09%, excess Cr may be crystallized as deposit and inverse influence may be exerted upon sound and images. When the Zr content is <0.01%, said maintaining effect is reduced, and when exceeding 0.1%, excess Zr may be crystallized as deposit and the inverse influence may be exerted upon sound or images.

[Problem to be solved by the invention 1 The winding wire (magnet wire) generally has an insulating film n! Apply J. This insulating film is formed by dissolving a resin such as poly-1 stellate, 1-boxy, silicone, or polyimide resin in a solvent, applying it to the conductor, and then baking it. In the case of tough pitch copper, oxygen-free copper, etc., when it goes through this heating process called baking, it recrystallizes. Therefore, even if tough pitch copper or oxygen-free copper has a crystal structure extending in an mIffI shape in the longitudinal direction, it cannot exhibit an oriented crystal structure after the baking process, that is, as a final product. .

By containing at least one member selected from the group consisting of 80, Or, and 7r, the oriented crystal structure as described above is maintained even when printed on the Institute of Technology Mel baking model. The reason why the content of A9 is set between 0.03% and 0.3% is that if it is less than 0.03%, the effect of maintaining the fibrous fiber will be reduced, and if it exceeds 0°3%, it will be 1JJf/f.
This is because the effect of the i-shaped fiber retention is almost saturated and no further improvement can be expected. In addition, containing excessive Ag not only becomes unnecessarily expensive, but also contains excess Ag.

When the Cr content was set to 0.01% to 0.09%, it was 0.0%.
If it is less than 0.01%, the effect of retaining the fibrous fibers will be small, and if it exceeds 0.09%, there is a risk that excess Cr will become precipitates, which will have a negative effect on the appearance and images. It is from. Furthermore, the Z r content is 0.01
The reason why Zr is set at ~0.1% is that if it is less than 0.01%, the effect of retaining the fibrous fibers will be small, and if it exceeds 0.1%, there is a risk that excess Zr will become a precipitate. This is because it adversely affects sound and images.
