    • There is provided a multilayer tube for transporting a fuel, a chemical liquid or a gas, which is based on a thermoplastic resin, in particular a polyamide resin, wherein its inner layer comprises an electroconductive thermoplastic resin in which a fine carbon fiber has been blended as an agent imparting an electroconductivity, and it excels in a molding processability, a fuel oil resistance and an antistatic property. This multilayer tube comprises at least two layers of (a) an outer layer comprising a thermoplastic resin, and (b) an inner layer comprising an electroconductive thermoplastic resin so that a surface resistivity is not more than 108 Ω; the electroconductive thermoplastic resin comprising a fine carbon fiber, wherein a graphite-net plane consisting solely of carbon atoms forms a temple-bell-shaped structural unit comprising closed head-top part and body-part with open lower-end, 2 to 30 of the temple-bell-shaped structural units are stacked sharing a common central axis to form an aggregate, and the aggregates are connected in head-to-tail style with a distance to form the fiber.

    • A floating magnetic head for use in a fixed-type magnetic disk drive has a slider with a coil groove defined therein and opening at the trailing end of the slider. The coil groove has a bottom remote whose width is smaller than the width of the coil groove at the trailing end. The coil groove may be tapered linearly or stepwise, and the bottom may be arcuate in shape. The slider has upper and lower walls between which the coil groove is defined, the upper and lower walls being progressively thicker toward the bottom of the coil groove. The progressively thicker upper and lower walls are mechanically strong against shocks and other excessive forces, and also against stresses applied from coils wound in multiple layers on a core tip inserted in a slit that is defined in the slider across the coil groove.
    • 用于固定式磁盘驱动器的浮动磁头具有限定在其中的线圈槽并在滑块的后端开口的滑块。 线圈槽具有底部遥控器,其宽度小于后端的线圈槽的宽度。 线圈槽可以是直线状或阶梯形的,并且底部可以是弓形的。 滑块具有限定线圈槽的上壁和下壁,上壁和下壁朝向线圈槽的底部逐渐变厚。 逐渐变厚的上壁和下壁机械强度抵抗冲击和其他过大的力,并且还抵抗在卷绕在多个层上的线圈上施加的应力上,该芯线插入插入在滑块上的狭缝中,该狭缝限定在线圈槽上。
