    摘要: A switching apparatus for constructing a system integrating a telephone switching network and a LAN includes: line interface sections, each connected to a transmission line for transmitting a signal on which low-speed data and high-speed data are multiplexed; a low-speed data switch for switching low-speed data demultiplexed in each line interface section; a high-speed data switch for switching high-speed data demultiplexed in each line interface section; and a processor for monitoring and controlling the data traffic passing through the low-speed data switch and high-speed data switch. An address in a designated position in the high-speed data demultiplexed in each line interface section is read out, whereby the association between the low-speed data terminal and high-speed data terminal is identified and stored. By referring to this association, management of LAN terminals can be performed using the maintenance operation procedures used in a conventional electronic switching apparatus.

    摘要: A mist eliminator comprises a plurality of blades spaced apart in parallel with each other. Each blade has a step-like portion which curves smoothly up to a single plateau. An elimination chamber is located on the plateau. The length from the eliminating chambers to gas outlets is less than that from gas inlets to the eliminating chambers and the parts of the blades from the eliminating chambers to the gas outlets is substantially parallel with a direction in which a gas enters the eliminator. The eliminator is provided at least in the rear of the blades with washing water nozzles for spraying washing water against the gas outlets. The eliminator is capable of effectively collecting fine mist and removing solid particles adhered to the blades by washing water with ease and therefore has no risk of clogging of gas passages.
