摘要： PROBLEM TO BE SOLVED: To provide an electrode and a method for manufacturing the electrode that can contribute to the improvement of luminance of a cold-cathode fluorescent lamp and to the extension of a service life.
SOLUTION: The electrode is an electrode of bottomed cylinder shape used for the cold-cathode fluorescent lamp, and formed of a nickel alloy containing pure nickel and Y excelling in plastic working property. When the integrated intensity of X-ray diffraction of a (220) plane on the inner surface of the electrode is I(220) and the integrated intensity of X-ray diffraction of a (111) plane is I(111), the electrode satisfies I(220)/I(111)≥0.41. Since the presence ratio of the (111) plane is small, a work function and an etching rate of the electrode are small, and electric discharge property and sputtering resistance are enhanced. The electrode satisfying I(220)/I(111)≥0.41 can be obtained by performing impact molding to a linear material formed of the nickel alloy containing pure nickel and Y.

摘要翻译：要解决的问题：提供一种可以有助于提高冷阴极荧光灯的亮度和延长使用寿命的电极和电极的制造方法。
解决方案：电极是用于冷阴极荧光灯的有底圆柱形电极，由含有纯镍和镍的镍合金形成，具有优异的塑性加工性能。当电极内表面上的（220）面的X射线衍射的积分强度为I（220），（111）面的X射线衍射的积分强度为I（111）时，电极满足I（220）/ I（111）≥0.41。由于（111）面的存在比例小，电极的功函数和蚀刻速度小，因此放电特性和溅射电阻提高。满足I（220）/ I（111）≥0.41的电极可以通过对由含有纯镍和Y的镍合金形成的线性材料进行冲压成型获得。（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ultrafine Cu-Ag alloy wire suitable for a shield conductor of a coaxial cable and method for manufacturing the same, and also to provide a coaxial cable. SOLUTION: The Cu-Ag alloy wire is used for a shield conductor of a coaxial cable, and contains 1-20 mass% of Ag, with the rest being Cu and an impurity, and has a conductivity of 82%IACS or above, a tensile strength of 800 MPa or above, and a wire diameter of 0.05 mm or below. By using the Cu-Ag alloy wire for the shield conductor, a coaxial cable having a superior shield property can be obtained. In manufacturing the Cu-Ag alloy wire, an intermediate heat treatment is applied at a heating temperature of 350-550°C to a rolling material in the middle of a rolling process. For the intermediate heat treatment, a relationship between the wire diameter of the rolling material to be applied with the intermediate heat treatment and the conductivity and tensile strength of a final wire obtained by applying a rolling process to the heat-treated material applied with the intermediate heat treatment is preliminarily found. The intermediate heat treatment is conducted when the wire has a predetermined diameter inversely calculated from the final wire diameter based on the relationship so that the Cu-Ag alloy wire having the final wire diameter may have a conductivity of 82%IACS or above and a tensile strength of 800 MPa or above.
