摘要： PROBLEM TO BE SOLVED: To make a plan for an efficient periodic inspection even by a person other than an expert by offering algorithm necessary to develop software on a computer system to diagnose a removing function of decay heat generated from fuel at periodic inspection time. SOLUTION: In an inspection or the like, a fuel direct cooling system on which a function of the system is not lost is selected (101) by screening, and whether or not a series of cooling system to introduce heat generated from fuel to the sea can be secured is judged (102). That is, in order close to the sea to which heat of the fuel is finally released, whether or not an inlet channel is secured (103), whether or not a seawater cooling system corresponding to a direct cooling system is secured (104) and whether or not an intermediate fresh water cooling system corresponding to the direct cooling system is secured (105 and 107), are judged in order, and when finally judged that a series of these cooling equipments are not inspected (106 and 108) and a function is maintained, it is judged that a cooling function exists (109). This routine is judged every day in the whole period of a periodic inspection.

摘要： PROBLEM TO BE SOLVED: To prevent the erroneous release of a main steam relief safety valve by providing a test signal circuit on a start signal circuit in conducting a test of the start signal circuit of an automatic decompression system. SOLUTION: A start signal circuit is provided with AND gates 39a, 39d, 39g, 39i, 39j and OR gates 39b, 39c, 39e, 39f, 39h. During the test of an automatic decompression system start signal circuit, start signals of a group A of a container pressure high (A) signal and a nuclear reactor water level low (A) signal and a group C of a container pressure high (C) signal and a nuclear reactor water level low (C) signal are not outputted concurrently. A test signal circuit is provided with switches, relays, and contact points. When the automatic decompression system start signal circuit is tested with a simulated start signal during the operation of the nuclear reactor of an automatic decompression system, a group C test is started after a group A test of the start signal is conducted, however the signal of the group C is not outputted unless the self-hold signal circuit of the group A is reset.

摘要： PROBLEM TO BE SOLVED: To provide a computer management device capable of rapidly performing start and stop of a screen saver, while improving the sureness of security against unauthorized use. SOLUTION: An IC tag 9 stores ID data of a use permitted person and is carried by a user. A screen saver control part 6 starts and stops the screen saver laying a computer 1 in an disabled state. A database 7a stores management data (ID data) of the user who is permitted to use the computer. An IC tag transmitting and receiving part 8 transmits radio waves to the IC tag 9 to read the ID data. A use propriety determination part 7c collates the ID data read by the transmitting and receiving part 8 with the management data in the database 7a to determine the use propriety. A screen saver operation instruction part 7d makes the control part 6 start the screen saver when the determination part 7c determines that the use is improper. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an abnormality detection method and system that can relieve the load on a supervisor with high precision in order to solve problems of conventional systems in many of which among various ways of image supervision the supervisor always supervises the entire image and discriminates whether or not abnormality is in the image thereby making less improvement of accuracy of the supervisory. SOLUTION: In this method, an area surrounded on an image of a supervisory object by line segments is set as a supervisory notice area, the supervisor takes notice of the line segments set as the supervisory area for the abnormity of the supervisory area, supervises a state change in the line segments for a predetermined period and discriminates whether or not the supervisory notice area is abnormal based on the state change of the line segments. Furthermore, time series image data for a predetermined period before and after the occurrence of abnormity are stored.
