In some aspects, an encryption key setting method includes inputting a code string, selecting a generating procedure for generating a code string from a plurality of generating procedures that were previously set, generating a code string using the inputted code string based upon the selected generating procedure, and setting the generated code string as an encryption key.
摘要:
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.

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. Next, the carrier solution is slowly flowed at a predetermined speed, so that the gas exchange is fully conducted in the gas exchanger 7, the output potential difference &Dgr;V(t) between the reference pH electrode 14 and the measuring pH electrode 16 at time t is found, and the difference &Dgr;&Dgr;V(t) between the &Dgr;V(t) measured at this time and the &Dgr;V(0)obtained at the last time, is obtained. This value corresponds to the correct gas partial pressure change.

摘要:
A method for measuring trace amounts of analyte substance(s), which utilize a pH electrode is disclosed. This method is by far simpler than conventional optical detecting systems. The apparatus for practicing the method is also disclosed. By the use of pH electrode, the apparatus is compact, inexpensive and easy to operate, and hence usable in small-size and medium-size hospitals or clinical laboratories and by patient's bedside.
