    • The polyvinyl chloride-based fiber of the present invention is a polyvinyl chloride-based fiber formed of a vinyl chloride-based resin composition that is obtained by blending, with respect to 100 parts by weight of a mixture (a) containing 95 wt % to 50 wt % of a vinyl chloride-based resin and 5 wt % to 50 wt % of a chlorinated vinyl chloride resin, 0.5 parts by weight to 3 parts by weight of a hydrotalcite-based thermostabilizer (b), 0.5 parts by weight to 2 parts by weight of a metallic soap-based thermostabilizer (c), and 0.5 parts by weight to 1.2 parts by weight of β-diketone as a stabilizing aid (d). This polyvinyl chloride-based fiber has excellent spinnability, excellent transparency, small initial coloration and excellent colorability, and thus has a high commercial value as artificial hair for hair adornment, and can be used widely for practical goods and fashion purposes. Moreover, due to this property, the polyvinyl chloride-based fiber also can be applied to a field of industrial materials and the like besides artificial hair.
    • 本发明的聚氯乙烯系纤维是由氯乙烯系树脂组合物形成的聚氯乙烯系纤维,其相对于100重量份的含有95重量%以上的混合物(a)〜 50重量%的氯乙烯类树脂和5重量%〜50重量%的氯化氯乙烯树脂,0.5重量份〜3重量份的水滑石类热稳定剂(b),0.5重量份〜2重量% 重量份的金属皂基热稳定剂(c)和0.5重量份至1.2重量份的作为稳定助剂的β-二酮(d)。 该聚氯乙烯类纤维具有优异的可纺性,优异的透明性,初期着色性和着色性优异,作为头发装饰用的人造​​毛发具有高的商业价值,可广泛用于实用的商品和时尚用途。 此外,由于该性能,聚氯乙烯系纤维也可以应用于除人造毛发以外的工业材料等领域。

    • A first signal generator and a second signal generator for setting measuring conditions of a connection pin of a device under test are disposed in each of a number of signal transmission circuits. Each of the signal generators stores therein information for setting a measuring condition in the form of a digital data, which is D-A converted, and this D-A converted output determines the measuring condition. Analog switches are disposed for selecting as a measuring condition of the connection pin either the D-A converted output of the first signal generator or that of the second signal generator. A first discriminator and a second discriminator for discriminating the quality of measured results of the connection pin of the device under test are disposed in each of the signal transmission circuits. In each of the discriminators, reference value information for discriminating the quality is stored in the form of digital data, which is D-A converted, and this D-A converted output and a measured result of the connection pin are compared with each other. A controller controls the operation of each of the signal transmission circuits.
    • 设置在多个信号传输电路的每一个中的第一信号发生器和用于设置被测器件的连接引脚的测量条件的第二信号发生器。 每个信号发生器存储用于设置D-A转换的数字数据形式的测量条件的信息,并且该D-A转换的输出确定测量条件。 配置模拟开关用于选择连接引脚的测量条件,即第一信号发生器的D-A转换输出或第二信号发生器的输出。 在每个信号传输电路中设置用于区分被测器件的连接引脚的测量结果的质量的第一鉴别器和第二鉴别器。 在每个鉴别器中,用于识别质量的参考值信息以D-A转换的数字数据的形式存储,并且将该D-A转换输出和连接引脚的测量结果相互比较。 控制器控制每个信号传输电路的操作。
