The electric resistance value of the electro-conductive fibers ranges from 1×10?2 to 1×1010 ?/cm, and the standard deviation of the logarithm of the electric resistance value is less than 1.0. The thickness of the electro-conductive layer ranges from 0.1 to 5 ?m, and the ratio of the carbon nanotubes may be 0.1 to 50 parts by mass relative to 100 parts by mass of the synthetic fibers. The electro-conductive layer may further contain a binder. The electro-conductive fibers may be produced by immersing the synthetic fibers in a dispersion with vibrating the synthetic fibers to form the electro-conductive layer adhered to the surface of the synthetic fibers.

  • Patent number: 8234322
    Abstract: The present invention relates to a random-number generating apparatus and method for generating physical random numbers in accordance with noises randomly generated by a noise generating element, and allows for generating true random numbers at a high speed and uniformizing the generation frequency of each random number value, even in a simplified circuit configuration. The random-number generating apparatus is operable to amplify a waveform based on thermal noises generated in a thermal-noise generating element, and generate a random pulse at the time when the amplified output signal exceeds a given threshold from the state of being less than the threshold. The random-number generating apparatus is also provided with a reference-pulse generator for generating a reference pulse having a constant period, and a timer for measuring a time interval between the reference pulse and the random pulse. The measured value in the timer is output as a random number value.
