Abstract: A network facsimile system is configured such that telephone numbers which a relay server can user are assigned to communication terminals. When a image is transmitted from the communication terminals to destinations outside the network facsimile system via the relaying server, the assigned telephone numbers are used as station signal numbers. When an image is transmitted to the relaying server from origins outside the network facsimile system, destination communication terminals are identified based on the telephone numbers assigned thereto and receiving telephone numbers. Then, the image received by the relaying server is transmitted to the identified communication terminals.

Abstract: A network facsimile system has a communication terminal and relaying server. The network facsimile system is configured such that the communication terminal can transmit an image, through the relaying server, to a destination terminal outside the network facsimile system, that the communication terminal transmits an image to the relaying server in accordance with a predetermined communication protocol. The relaying server transmits an image to the destination terminal in accordance with a facsimile communication protocol. The communication terminal includes a notification system that notifies a user of the communication terminal of an operation status information indicating an operation status of the network facsimile system during a relaying server side operation period.

Abstract: One end of a thin-tube type solid phase in which a receptor specific for a material or an organism to be measured which can induce a pH-change of substrate solution is immobilized is soaked in a sample solution and then taken out therefrom. The one end of the thin-tube type solid phase is disposed in a measurement cell and a sensing portion of a pH electrode disposed in the measurement cell is in the vicinity of the one end of the thin-tube type solid phase. The measurement cell and the thin-tube type solid phase are filled with a substrate solution so that a reaction takes place. Thereafter, the substrate solution in the thin-tube type solid phase is moved to the sensing portion by a solution feed pump. The output of the pH electrode at this timing is detected.

Abstract: The conduit tube 3 and the conduit tube 4 to flow the carrier solution to the gas exchanger 7 are provided, and in the conduit tube 3, the reference pH electrode 14 is provided, and in the conduit tube 4, the measuring pH electrode 16 is provided, both pH electrodes preferably being chosen of the ISFET type (Ion-Sensitive Field-Effect-Transistor). The gas exchanger 7 is partitioned from the outside by the gas permeable membrane 6. Initially, the gas exchange section 1 is inserted into the test substance, and next, the carrier solution is flowed at the speed of a degree in which the gas exchange is not conducted in the gas exchanger 7. The output potential difference &Dgr;V(0) between the reference pH electrode 14 and the measuring pH electrode 16 at this time, is found.
