摘要： PURPOSE:To prevent the increase of overhead as well as the deterioration of the system performance by measuring the ratio of the updated pages by transactions at an optional interval larger than the check point interval and switching the assuring system of a residence table according to the measured updating ratio. CONSTITUTION:A residence table group 42 which is resident in a main memory 31 is divided into optional input/output units. When the contents of a residence table are stored in nonvolatile memories 34 and 35 at start of a system, the input/output units updated for running transactions are monitored at an interval larger than the check point interval. When the updating ratio per check point interval is low, only the input/output unit including the updated part is written into memories 34 and 35 respectively. While the contents of the residence table are all written into the memories 34 and 35 when said updating ratio is high. In such a way, the overhead is reduced when the contents of the residence table are written at the check point and the deterioration of the system performance can be avoided by switching the assuring system for the contents of the residence table.

摘要： PROBLEM TO BE SOLVED: To surely perform radiation and temperature measurement by finding the incident position and intensity of optical fiber radiation for radiation from the arrival time difference of discriminated scintillation light, and besides, finding a temperature position from the arrival time difference between Stokes light and antiStokes light. SOLUTION: Scintillation light 10 of one end side of a scintillation fiber 8 is input to a time difference measuring circuit 17 through a connector 9a, an optical fiber 15a and the like, and on the other hand, the scintillation light 10 of the other end side is input to the circuit 17 through a connector 9b, an optical fiber 15b and the like. A signal processing circuit 14 finds the incident position and intensity of radiation 100 in the scintillation fiber 8 on the basis of a time difference. The circuit 14 measures temperature of the optical fibers 6a, 6b by the ratio of Stokes light 11a to anti-Stokes light 11b, and the pulse generation time of a pulse generator 1 and a measuring temperature position of the optical fibers 6a, 6b are specified on the basis of the time difference in which rear scattering light 70 reaches through light/electricity converters 13a, 13b.

摘要： PROBLEM TO BE SOLVED: To correctly measure a local temperature of an object. SOLUTION: An optical fiber 1 is fixed by an optical fiber-fixing layer 3 onto a plate-like body 2. A case 4 of a shape capable of enclosing the optical fiber 1 is mounted to the plate-like body 2 via a space 5 separated from the optical fiber 1. The case 4 not only prevents the optical fiber 1 from being influenced by surrounding temperatures, but protects the optical fiber 1 mechanically. No torsional stress acts to the optical fiber 1, thereby preventing the optical fiber as much as possible from being bent at random. A transmission loss is never increased. Accordingly, the optical fiber can surely function as a spot sensor part.

摘要： PROBLEM TO BE SOLVED: To facilitate conveying operation and to reduce an installation area for a module aggregate by installing a support structural body on the side wall of an adiabatic containers housing a plurality of pieces of high-temperature sodium secondary batteries such as sodium-sulfur batteries. SOLUTION: Because of installation of a support structural body 31, an installation area for a high-temperature sodium secondary battery module may be increased in comparison with that having no support structure 31, however, the support structure 31 is directly installed on the side wall of an adiabatic container 2 and a lateral clearance 40 between a base and the module is eliminated between the support structure 31 and the module, so that the installation area can be greatly reduced as against that for an existing structure module aggregate. A lid is mounted on each adiabatic container 2 for each high- temperature sodium secondary battery module, and the module can be handled independently of each other. Therefore, after a plurality of modules is conveyed to a field, the modules can be laminated so as to be installed by fixing between the support structures 31 together in the field.

摘要： PROBLEM TO BE SOLVED: To reduce the change processing of group constitution and to enable early detection concerning a remote procedure call(RPC) processing system for calling a group server. SOLUTION: When adding a server to a server group 80, an additional report is outputted from a group constitution change reporting part 70 to a processor provided with a server in the group such as a processor 5, for example. An RPC processing part 50, which receives this report, holds group constitution change information reporting the addition of new procedure. An RPC request source such as a client 15 of processor 2, for example, issues the RPC request of 'QSORT' to servers 25, 35 and 45 in the server group 80 and correspondent servers in the group are respectively executed. When executing a server 421 and transmitting the executed result to the request source, the processor 5 adds this group constitution change information. When any change in group constitution is detected out of a response message, an RPC processing part 10 at the request source updates its own address information by calling all the address information from an address managing part 60.

摘要： PROBLEM TO BE SOLVED: To improve the throughput of a distributed processing system in a network system where terminals of plural data of endian forms exist mixedly and data are communicated by broadcasting. SOLUTION: A terminal has a weighting value transmission means 112 of the terminal itself to periodically transmit contents of a weighting value hold means 111 of the terminal itself. A weighting value reception means 113 receives a weighting value from another terminal. An endian form determination means of communication data 114 and an endian form determination value of communication data hold means of communication data 115 are provided. When being started from a data communication means 117 or an application 118, an endian form conversion means of communication data 116 performs the conversion processing if the endian form of a broadcasting group and that of the terminal itself are different from each other.
