    • According to an aspect, to realize a transient correction circuit capable of performing a high-speed operation without being affected by low-frequency noise and allow to remove only the low-frequency noise without changing a reproducing waveform, an output from a HPF for removing the low-frequency noise of a reproduced signal is supplied to a waveform correction circuit for correcting the transient of the reproduced signal, which is generated by the HPF. The waveform correction circuit is constituted by a LPF, an adder for adding an output from the LPF and the output from the HPF, and a quantization circuit for quantizing an output from the adder. The HPF and the LPF have the same time constant. According to another aspect, to precisely compensate a DC component necessary for signal reproduction, which is lost by capacitive coupling, in reproduction of a signal recorded by high-density or high-transfer recording, the low-frequency component of the reproduced signal is removed by a HPF corresponding to a coupling capacitor. A comparison circuit compares an output from the HPF with a predetermined reference level by a comparator, thereby generating a binary output. A LPF performs time integration of the binary output through a gain adjustment circuit. An output whose sag is corrected is calculated by an operational amplifier according to the output from the LPF and the HPF.
    • 根据一个方面,为了实现能够进行高速运行而不受低频噪声影响的瞬态校正电路,并且仅在不改变再现波形的情况下仅移除低频噪声,则从用于去除的HPF的输出 再现信号的低频噪声被提供给用于校正由HPF产生的再现信号的瞬态的波形校正电路。 波形校正电路由LPF,用于将来自LPF的输出和HPF的输出相加的加法器和用于量化来自加法器的输出的量化电路构成。 HPF和LPF具有相同的时间常数。 根据另一方面,为了在由高密度或高转印记录记录的信号的再现中精确地补偿由电容耦合丢失的信号再现所需的DC分量,则再现信号的低频分量被去除 通过对应于耦合电容器的HPF。 比较电路通过比较器将来自HPF的输出与预定的参考电平进行比较,从而生成二进制输出。 LPF通过增益调整电路执行二进制输出的时间积分。 根据LPF和HPF的输出,通过运算放大器计算其下垂的校正的输出。

    • A guide apparatus has a standard end plate split into a pair of split parts that can be positioned with respect to each other with high accuracy and firmly secured to each axial end of a moving block body without fear of displacement during use. The guide apparatus has a moving block relatively movably attached to a track rail. The moving block body has in a section perpendicular to the axial direction a geometry that allows the moving block body to be assembled to the track rail at an intermediate part of the track rail. The end plate consists essentially of a pair of split parts that are splittable to right and left in the width direction of the end plate. One split part has a positioning pin projecting from a parting surface thereof. A positioning hole fittable with the positioning pin is provided in a parting surface of the other split part. The positioning pin is fitted into the positioning hole to form an end plate assembly. The end plate assembly is secured to one end of the moving block body in the direction of relative movement by using securing screws passed through securing screw holes provided in the split parts, respectively.
