    摘要： A wireless LAN system which allows the transmission and reception of various data without lowering the transmission efficiency and the transmission quality even in an overlapping environment of areas of a plurality of wireless LANs and a base station apparatus therefor are provided. The wireless LAN system has a plurality of wireless LANs including base stations and wireless terminal devices, and the base stations and the wireless terminal devices in the wireless LANs communicate while sequentially hopping carrier frequencies to conduct the intercommunication between the base stations in the wireless LANs through inter-base station communication units. Each base station includes a unit for transmitting and receiving a specific frame to and from other base stations through the inter-base station communication unit to determine whether its own base station is a master base station or not and a unit for assigning different hopping start frequencies to its own base station and other base stations when its own base station is determined as the master base station.

    摘要： An optical amplification system capable of operating without being affected by the waveform of the incoming optical signal is provided for amplifying the optical signal in its optical waveguide by the effect of stimulated emission of a fluorescent substance induced by pumped light. According to a first aspect of the invention, an optical amplification system turns on its pumping source 8 when there is an optical signal s1 in the optical waveguide 5 whereas the pumping source 8 is kept off as long as no optical signal s1 is found in the optical waveguide 5 so that, when the pumping source 8 is turned on, pumped light from the pumping source 8 is fed to the optical waveguide 5 with a delay of time relative to the incoming optical signal s1. According to a second aspect of the invention, the inside of the optical waveguide 5 is constantly kept under an excited condition so that, when no optical signal s1 is found in the optical waveguide 5, dummy light s3 is fed to the optical waveguide 5, whereas no dummy light s3 is fed to the optical waveguide 5 once an optical signal s1 is introduced to the optical waveguide 5. With such an arrangement, since no optical amplification takes place at the rising edge of an incoming optical signal and hence the operation of optical amplification is not dependent on the waveform of the incoming optical signal, a safe and stable optical amplification system can be established.

    摘要： A hydraulic drive system for a civil-engineering and construction machine, includes an unloading valve connected to a discharge line of a hydraulic pump for relieving a hydraulic fluid from the hydraulic pump to a tank when a differential pressure between a delivery pressure of the hydraulic pump and a load pressure of an actuator exceeds a first predetermined value, for controlling the differential pressure. The unloading valve has a spool, a first receiving chamber arranged adjacent to one end of the spool, and a second pressure receiving chamber arranged adjacent to the other end of the spool, the delivery pressure of the hydraulic pump being introduced into the first pressure receiving chamber and the load pressure of the hydraulic actuator being introduced into the second pressure receiving chamber. The unloading valve is provided with a restrictive communication path for selectively communicating the first pressure receiving chamber and the second pressure receiving chamber with each other, whereby when a phase deviation exists between the delivery pressure P.sub.s of the hydraulic pump and the maximum load pressure P.sub.L transmitted to the unloading valve as signal pressures, oscillation of the unloading valve is prevented.
