Abstract: A fluid container unit including: a container coupling for coupling a supply/discharge port of a first container with a supply/discharge port of a second container; a single nozzle member having a nozzle tube; a connection cap having a first end for holding a base portion of the nozzle member and a second end for covering one side of the container coupling by fitting around an outer periphery thereof; an intermediate adaptor having a pair of pusher elements facing the first and the second supply/discharge ports, respectively; and a supply/discharge port opening mechanism for moving the intermediate adaptor toward the container coupling and opening the supply/discharge ports by the pusher elements. The pusher elements are movably held in a direction along a longitudinal axis of the nozzle tube in the connection cap.

Abstract: A communication apparatus having a temporary managing portion for controlling a temporary memory, a main managing portion for controlling a main memory and an operation control portion.

Abstract: A communication apparatus having a temporary managing portion for controlling a temporary memory, a main managing portion for controlling a main memory and an operation control portion. The operation control portion causes the temporary managing portion and the main managing portion to utilize the state information or the history and state information for obtaining probability of deletion or transmission and probability of delay with regard to each data frame of framed data for discharge and to control, on the basis of the obtained probability of deletion or transmission and the obtained probability of delay, deletion or transmission of the data frame of the framed data for discharge and delay for transmission of the data frame of the framed data for discharge on the occasion of the transmission thereof.

Abstract: A communication apparatus according to the invention can be applied to constitute each of relay nodes in a novel wireless communication network, in which the number of relaying stages formed with the relay nodes can be freely set without restriction by the amount of communication information to be processed, and consequently, a multistage-relayed communication extending over a long distance can be carried out to realize a long-distance communication.

Abstract: A communication apparatus according to the invention can be applied to constitute each of relay nodes provided to constitute a novel communication network which avoids problems brought about by one or more bottlenecks formed in the communication network to result from the convergence of communication traffic induced in one or more relay nodes in the communication network. The communication apparatus comprises a temporary managing portion 16 for controlling a temporary memory means 15a, a main managing portion 18 for controlling a main memory means 17 and an operation control portion 20.

Abstract: A communication apparatus according to the invention can be applied to constitute each of relay nodes provided to constitute a novel communication network which avoids electric wave collision arising on a communication channel without carrying out “carrier sense” or operations for transmitting and receiving control information, such as “RTS”, “CTS”, and so no. The communication apparatus comprises a temporary managing portion 16 for controlling temporary memory means 15, a main managing portion 18 for controlling main memory means 17 and an operation control portion 20.
