    • The present invention provides a mold for fine electroforming M having a simple structure. In order to improve the productivity of a metal product, an electrode portion can be arranged with a much higher density, and a metal thin film formed on the electrode portion can easily be peeled off. The present invention provides a manufacturing method for manufacturing the mold M with a higher accuracy and by an easier way.The mold for fine electroforming M has a conductive substrate 1 to function as a cathode during electroforming and insulation layer 2 having an opening 21, which has a shape corresponding to a shape of a plane shape of the metal product P and is through to the conductive substrate 1, and composed of an inorganic insulation material having a thickness T2 of not less than 10 nm and less than one-half the thickness T1 of the metal product P. The surface of the conductive substrate 1 exposed at the opening 21 is adapted to serve as the electrode portion.The manufacturing method of the mold M has steps of: forming an inorganic thin film 2′ to grow into the insulation layer 2 in an area excluding an area, where resist film R is pattern-formed, on the surface of the conductive substrate 1; and removing the resist film R to form the opening 21.

    • A cold-cathode fluorescent lamp having high brightness with long life and an electrode for this lamp are offered. The electrode comprises a base and a covering layer that covers the surface of the base. The base is formed of one metal selected from nickel, a nickel alloy, iron, and an iron alloy. Consequently, a base having a shape, such as a cup, can be easily produced. The covering layer comprises (a) a surface layer made of tungsten or molybdenum and (b) a bonding layer that is made of zinc alloy and that is placed between the base and the surface layer. In comparison with nickel and iron, tungsten and molybdenum are resistant to sputtering, have a small work function, and have a high melting point. The presence of the bonding layer enables sufficient bonding between the surface layer and base. A cold-cathode fluorescent lamp provided with the foregoing electrode can suppress the reduction in brightness and the consumption of the electrode. Therefore, it has high brightness and long life.
    • 提供具有高亮度和长寿命的冷阴极荧光灯和用于该灯的电极。 电极包括覆盖基底表面的基底和覆盖层。 基体由选自镍,镍合金,铁和铁合金中的一种金属形成。 因此,可以容易地制造具有诸如杯子的形状的底座。 覆盖层包括(a)由钨或钼制成的表面层和(b)由锌合金制成的并且位于基底和表面层之间的粘合层。 与镍和铁相比,钨和钼耐溅射,功函数小,熔点高。 结合层的存在使得表面层和基底之间能够充分地结合。 设置有上述电极的冷阴极荧光灯可以抑制亮度的降低和电极的消耗。 因此,它具有高亮度和长寿命。

    • A cold-cathode fluorescent lamp having high brightness with long life and an electrode for this lamp are offered. At least one part of the electrode surface is formed by using one material selected from the group consisting of rhodium, palladium, and alloys of these. For example, a surface layer made of the foregoing material is formed on a base. To increase the bonding strength between the surface layer and the base, a bonding layer made of gold or gold alloy is formed on the base. Because a metal such as rhodium is resistant to alloying with mercury and has a high melting point, a cold-cathode fluorescent lamp provided with an electrode made of the foregoing metal can suppress not only the consumption of the mercury due to the formation of an amalgam but also the reduction in brightness due to insufficient discharging. Furthermore, because the lamp can suppress the consumption of the mercury and electrode, the lamp has long life.
    • 提供具有高亮度和长寿命的冷阴极荧光灯和用于该灯的电极。 电极表面的至少一部分通过使用选自铑,钯及其合金中的一种材料形成。 例如,在基材上形成由上述材料制成的表面层。 为了增加表面层与基体的接合强度,在基材上形成由金或金合金构成的接合层。 由于诸如铑的金属对汞的合金化具有高熔点,所以设置有由上述金属制成的电极的冷阴极荧光灯不仅可以抑制由汞齐形成的汞的消耗 而且由于放电不足导致的亮度降低。 此外,因为灯可以抑制水银和电极的消耗,所以灯寿命长。
