摘要:
The present invention provides a heat-shrinkable polyphenylene sulfide-based tube containing a resin composition (A) including a thermoplastic polyphenylene sulfide-based resin (a) as a main constituent, having a difference of 35° C. or more between the cold crystallization temperature Tc as measured by a differential scanning calorimetry in accordance with JIS-K7121 and the glass transition temperature Tg measured in the same manner, and having the glass transition temperature Tg between 65° C. and 85° C.; and the invention provides a component covered with the tube. The heat-shrinkable polyphenylene sulfide-based tube fulfills the characteristics required for a heat-shrinkable tube, such as heat resistance, low-temperature shrinkage characteristics, electrical characteristics, chemical resistance, and electrolytic solution resistance.

摘要:
A first bit-sequence, which is to be transmitted from a control section to an authentication chip according to an encoding scheme that transmits each one and zero by a pulse with a width of 200 μsec and 100 μsec respectively, is converted to a second bit-sequence to be transmitted according to NRZ encoding. The converted second bit-sequence is stored in a register with the MSB of the second bit-sequence aligned in the MSB of the register. Timing to set the pulse width for transmission of a one or zero by NRZ encoding is performed repeatedly, and at the start of each timed interval, the signal transmission level output to the authentication chip is set corresponding to the value of the bit stored in the MSB of the register. After setting the signal transmission level, the register is shifted left one bit.
