摘要:
The selection range of antenna candidates effective for MIMO communication is widened in a base station to increase the throughput of MIMO communication. A terminal sends a sounding signal at given time intervals with the maximum transmission power or with an antenna selection transmission power threshold or larger. With this transmission, since the number of antenna candidates that receive the signal is increased at a base station in the distributed antenna system, the radio propagation channel state between the terminal and the base station apparatus is checked to select the combination of antennas having good orthogonality. Before the terminal sends the sounding signal, the terminal reserves beforehand the transmission timing of the sounding signal or performs carrier sensing to determine whether a surrounding terminal is sending a signal to avoid the collision/interference of packets of sounding signals between terminals.

摘要:
An impact tool for simultaneously providing a rotational force and an impact force to an object has an output shaft rotated by a motor, hammer for intermittently providing an impact force to the output shaft, hammer holder for movably holding the hammer, and an impact force generator for generating the impact force from an output of the motor. An air chamber is formed between the hammer and the hammer holder such that a volume of the air chamber is variable in response to a position of the hammer relative to the hammer holder. In addition, the hammer receives a bias force generated in a direction toward the output shaft by a biasing device. This bias force effectively increases the impact force in cooperation with an air pressure caused by a volume change of the air chamber.
