The asynchronous data burst transfer circuit includes a data burst transfer oscillation circuit which outputs n strobe signals of mutually different phases, plural parallel-serial conversion circuits which convert n-bit parallel signals into serial signals, and plural serial-parallel conversion circuits which convert serial signals into n-bit parallel signals. The resulting sampled signals are used for power system-wide protection, control, monitoring and metering. The lever actuates the sliding hood to compressively secure a fishing reel to the fishing rod.
