    • Embodiments of the invention provide the manufacturing method for a magnetic disk drive that includes the process steps of detecting and processing in a simplified way the defective sectors causing a reading error at low operating environmental temperatures. In one embodiment, defective sectors are detected by read/write testing at high operating environmental temperatures from, for example, 40° C. to 65° C. Reading the data written on the defective sectors makes it obvious that the gain in a high-frequency band is reduced. After test data has been written onto each sector, the filtering coefficient of an FIR element that is set for a data-reading system is changed from the optimum value. The frequency gain is thus reduced. Next, the test data is read and the sectors that have caused a reading error are registered as defectives. Modifying a filtering coefficient value of the FIR filter reduces the gain of the data-reading system in the high-frequency band, thus allowing detection of the defective sectors at which the reading error emerges at low operating environmental temperatures.
    • 本发明的实施例提供了一种用于磁盘驱动器的制造方法,其包括以简单的方式检测和处理在低操作环境温度下引起读取误差的缺陷扇区的处理步骤。 在一个实施例中,通过在例如40℃至65℃的高操作环境温度下的读/写测试来检测缺陷扇区。读取在缺陷扇区上写入的数据使得显而易见的是, 频带减少。 在将测试数据写入每个扇区之后,将为数据读取系统设置的FIR元件的滤波系数从最佳值改变。 频率增益因此降低。 接下来,读取测试数据,并将引起读取错误的扇区注册为缺陷。 修改FIR滤波器的滤波系数值降低了高频带中的数据读取系统的增益,从而允许检测在低操作环境温度下出现读出误差的缺陷扇区。

    • A vehicle steering telescopic shaft having a male shaft and a female shaft so fitted to each other as not to be rotatable but to be slidable. First torque transmitting members are disposed between the male shaft and the female shaft, and roll when the male shaft and the female shaft make relative movements in axial directions. Elastic members are disposed adjacent in a radial direction to the first torque transmitting members and restrict them when rotated and apply a pre-load to the male shaft and the female shaft through the first torque transmitting members when not rotated. Second torque transmitting members are provided between the male shaft and the female shaft, and slide when the male shaft and the female shaft make the relative movements in the axial directions, and transmit a torque when rotated.

    • A glow plug according to one embodiment of the present invention includes a cylindrical metallic shell, an electrode rod disposed in a rear portion of the metallic shell, a heater disposed in a front portion of the metallic shell, and an electric insulator provided between an inner surface of the metallic shell and a circumferential surface of the electrode rod to keep the electrode rod insulated from the metallic shell. The metallic shell has a portion caulked to the electrode rod at a location axially corresponding to the electric insulator so that the circumferential surface of the electrode rod becomes deformed to define therein a recessed portion. The caulked portion is engaged in the recessed portion with the caulked portion with the electric insulator interposed between the caulked portion and the recessed portion, thereby securing the electrode rod in the metallic shell.
