Abstract: An objective is to provide a call center system operable in accordance with various signaling specifications without causing an automatic call distributor to cope with the various signaling specifications. A call-originator terminal 101 includes a virtual call device 105 transmitting a different signal to a call center 100 from signaling. The call center 100 includes an automatic call distributor 118 selecting a terminal in a call-center-terminal group 102 upon receiving the signal from the virtual call device 105. In addition, the call-originator terminal 101 and the call center 100 include respective telecommunication-device control devices 107, 115, giving, to either one of the call-destination terminal 113 selected by the automatic call distributor 118 and the call-originator terminal 101, a telecommunication device ID of the other terminal, and causing the one terminal to start signaling for transmitting an actual call to the other terminal based on the telecommunication device ID.

Abstract: It is an objective of the present disclosure to provide a controlling apparatus for communication-quality measuring which suppresses a reduction of a service communication quality in measurement of a communication quality through data transfer. A communication apparatus 100 is provided with a controlling apparatus for communication-quality measuring 102 that includes a communication-quality measuring unit 106 performing the data transfer with a communication load at a predetermined repetition to measure a communication quality value, a measurement-environment memory 107 storing the communication quality value, a measurement-environment monitor 108 monitoring a change in the stored value in the measurement-environment memory 107, and a measurement-load controlling unit 109 changing the communication load according to the change in stored value.

Abstract: A cryogenic vessel for a superconducting apparatus has an inner vessel which houses a freezing mixture and a winding of a superconducting apparatus. The inner vessel is surrounded by a vacuum insulating vessel which thermally insulates the inner vessel. A connecting pipe connects the inside of the inner vessel with the outside of the vacuum insulating vessel. A cylindrical dividing pipe which surrounds the connecting pipe with a radial clearance therebetween extends into the inner vessel and is connected between the inner end of the connecting pipe and the inner vessel. A gas flow passageway is formed between the inner end and the outer end of the connecting pipe, the passageway bordering on the inner or outer surface of the connecting pipe.
