Abstract: A sensor having a detecting part for detecting an environmental value representing change in physical amount of circumference environment by a fluid flowing into externally and a controlling part for discriminating abnormality in circumference environment based on the environmental value detected by the detecting part. A separating plate is provided inside a housing so as to separate two spaces in the height direction. A detection unit is provided in one space and a sounding body is provided in the other space. Apertures are provided in a side wall, thereby opening one space to the outside environment and letting the fluid to be measured flow into the space. Then, a flow path is formed inside the space in the housing, from the side wall forming the housing toward the detection unit, thereby proactively channeling the fluid to the detection unit.

Abstract: A call center system is composed of stations connected with each other through a WAN, and each station has the function of executing the waiting control of an incoming call and the function of executing the distribution control of the incoming call. A call history information transmitting and receiving control unit attaches call history information for indicating the state of waiting control and the state of transfer of the incoming call, to the incoming call to be transferred to another station, and conversely receives call history information attached to the incoming call transferred from another station. A waiting control unit executes the waiting control and distribution control of the incoming call corresponding to the call history information based on the call history information received by the call history information transmitting and receiving control unit.

The control part in the switching system, when being requested to establish an ACD call, selects a responsible main-operator terminal among plural responsible main-operator terminals and controls the switching part and the MXT in a manner that the selected main-operator terminal receives the ACD call, and selects a responsible sub-operator terminal among plural responsible sub-operator terminals and controls the switching part and the MXT in a manner that information transmitted with the established call can be listened by using the selected sub-operator terminal.

Abstract: When requests to attend a conference or requests to withdraw from a conference are issued from user terminals or voice input/output units, network equipment refers to connection addresses of these user terminals or voice input/output terminals to obtain user identification information (names, posts, etc.) from a table and communicates this user identification information to a conference server. The conference server collects conference-attendee information and conference-withdrawee information based upon the communicated user identification information. Further, a list of planned attendees at the conference is entered into the conference server via network equipment before the conference convenes, and the conference server compares the planned attendees and actual attendees at the conference and creates a list of conference absentees.

Abstract: A ferrite-type hot-rolled stainless steel sheet is composed of a selected class of elements in specified amounts. Even when cold rolling and its subsequent process steps are omitted, the hot-rolled steel sheet is sufficiently workable and excellent in surface roughening resistance and high-temperature fatigue properties after working. The steel sheet is easy to produce with a wide range of annealing temperatures.

Abstract: A LAN-to-LAN connecting unit sends a node-status confirmation packet PKTC to LAN terminals under its command to confirm the status of each terminal. Upon receiving the confirmation packet, a normal terminal sends a response packet PKTR back to the LAN-to-LAN connecting unit. However, a LAN terminal incapable of receiving data because of a pulled cable or some other problem cannot send back the response packet. The LAN-to-LAN connecting unit identifies and stores information indicating whether a LAN terminal is capable or incapable of reception depending upon whether the response packet is received. In a case where an incoming call has been terminated at a prescribed LAN terminal and this terminal is capable of reception, the LAN-to-LAN connecting unit receives the data sent from the other party's LAN terminal and transmits this data to the LAN. In a case where the prescribed LAN terminal is incapable of reception, the connecting unit disconnects the line immediately.

Abstract: A method of recovering and reproducing a tinning liquid containing Fe ions and other detrimental cations by the steps of removing cations from the tinning liquid by passing the tinning liquid or a diluted liquid of the tinning liquid through a strong-acid cation exchange resin to obtain a recovered acid, thereafter reproducing the strong-acid cation exchange resin and desorbing adsorbed cations into a solution containing an acid by passing the acid through the exchange resin to which the cations have been adsorbed, precipitating and separating Sn ions in the form of a precipitate of an Sn compound from the solution into which the cations have been desorbed while maintaining Fe ions as ions in this solution, mixing and dissolving the precipitate of the Sn compound or a compound reduced from the same in the recovered acid to reproduce and reuse the mixture of the Sn compound and the recovered acid as a tinning liquid, and discharging the solution containing Fe ions out of the system of the tinning liquid.
