    摘要： Disclosed herein are a cone valve and a manufacturing method thereof, wherein a cone which is installed inside a hollow body unit through which fluid flows, wherein the body unit is provided with left and right bodies, and the cone is disposed between the left and right bodies, left and right valve inclination surfaces are defined, inclined corresponding to an inclination surface of the cone, at the front ends of the left and right bodies, whereupon the cone can reciprocate forward and backward, thus opening or closing a flow passage.

    摘要： A servo track writer for use in a hard disc drive is provided, which includes a plate-shaped base member, a hard disc drive fixed on the upper surface of the base member, and a clock head unit spaced by a predetermined distance apart from the hard disc drive, for recording and reading out a clock signal on and from the hard disc drive, respectively. The servo track writer includes a sliding transfer unit for transferring the clock head unit toward or far from the hard disc drive, and an adjusting screw which extends from one side of a supporting member supporting the clock head unit toward the hard disc drive and adaptively contacts the side surface of the hard disc drive functioning as a stopper when the clock head unit moves toward the hard disc drive. The servo track writer can maintain the constant distance between a clock head unit and the hard disc drive since the adjusting screw installed in the supporting member supporting the clock head unit adaptively contacts one side of the hard disc drive functioning as a stopper, although the hard disc drive moves by a certain distance apart from the clock head unit due to an external force, to thereby detect a clock signal recorded on the hard disc drive with ease.

    摘要翻译： 提供了一种用于硬盘驱动器的伺服记录器，其包括板状基座部件，固定在基部部件的上表面上的硬盘驱动器以及与该部件间隔开预定距离的时钟头部件 用于分别在硬盘驱动器上记录和读出时钟信号的硬盘驱动器。 伺服轨迹写入器包括用于将时钟头单元朝向或远离硬盘驱动器传送的滑动转移单元和从支撑时钟头单元的支撑构件的一侧朝向硬盘驱动器自适应地接触的调节螺钉 当时钟头单元向硬盘驱动器移动时，硬盘驱动器的侧表面用作止动器。 由于安装在支撑时钟头单元的支撑构件中的调节螺钉自适应地接触用作止动器的硬盘驱动器的一侧，所以伺服轨迹写入器可以保持时钟头单元和硬盘驱动器之间的恒定距离，尽管硬 磁盘驱动器由于外力而离开时钟头单元移动一定距离，从而容易地检测记录在硬盘驱动器上的时钟信号。
