The difference between: a hardness H(5.0) at a point located at a distance of 5 mm from the central point of the core 4; and a hardness Ho at the central point is 6.0 or greater. The difference between: a hardness H(12.5) at a point located at a distance of 12.5 mm from the central point; and the hardness H(5.0) is 4.0 or less. The difference between a hardness Hs at the surface of the core 4 and the hardness H(12.5) is 10.0 or greater. The difference between the hardness Hs and the hardness Ho is 22.0 or greater. In the core 4, there is no zone in which a hardness decreases from the central point to the surface. A hardness H3 of the cover 8 is greater than a hardness H2 of the mid layer 6. The cover 8 is formed from a resin composition containing a polyamide copolymer including a polymerized fatty acid (a-1), sebacic acid and/or azelaic acid (a-2), and a polyamine component (a-3).

摘要： In the present invention, unlike a conventional circuit, discrimination is not made by integrating a logical code that includes “0” and “1” to some extent and produced from a random code, but repetition of an identical pattern of a well-known preamble signal added to a head portion of a signal is discriminated when a bit-rate of the signal is changed. More specifically, the repetition of the identical pattern is converted into a consecutive identical signal to generate the consecutive identical signal (having a length of tens bits to thousands bits). Although the consecutive identical signal is longer than a same-code continuation length included in the signal, and is shorter than a time constant necessary to the conventional circuit by about one to three digits. Therefore, an integration time can be shortened to the same degree as the generated consecutive identical signal length, and the bit-rate can be discriminated at high speed within a preamble signal receiving time.

摘要翻译： 在本发明中，与传统电路不同，不是通过将包含“0”和“1”的逻辑码在某种程度上进行积分而产生的，而是由随机码产生，而是重复公知前导码的相同模式 当信号的比特率改变时，鉴别加到信号头部的信号。 更具体地，将相同图案的重复转换为连续的相同信号，以产生连续相同的信号（具有十位至数千比特的长度）。 虽然连续相同的信号比包括在信号中的相同代码连续长度更长，并且比常规电路所需的时间常数大约一到三位数。 因此，可以将积分时间缩短到与所生成的连续相同的信号长度相同的程度，并且可以在前导码信号接收时间内以高速判别比特率。
