摘要： A chain-like self-moving robot includes three or more capsule units (a 1 , a 2 , ..., a N ) connected to one another in a string by means of couplers (b 1 , b 2 , ..., b N ; 112K). By expanding and contracting intercapsule spaces in a predetermined sequence so that a smaller number of the capsules are moved while a larger number of capsules remain stationary, the chain-like robot can move forwardly or backwardly.

摘要： Method and apparatus for evaluating location (P) of an ! unknown sound generated in a structure (1) such as a pressure vessel. A plurality of sound detectors (S) are mounted on the structure for detecting sounds generated in the structure. On the basis of sound information of the unknown sound source derived from the outputs of the detectors, the location where the unknown sound is produced is determined. To this end, reference sounds (A, B, C, I) are first generated at a plurality of known reference sound source positions, wherein information of the reference sounds derived from the outputs of the detectors are stored in a storage unit (140). Equi-pattern-distance curves each of which is in an equal pattern distance between a supposed unknown sound source and each of the reference sound sources are calculated on the basis of the reference sound information. The equi-pattern-distance curves are further corrected in accordance with the reference sound information. Upon occurrence of an unknown sound, pattern distances between the desired reference sound source positions and the unknown sound source position are calculated through pattern recognition procedure from the sound information derived from the outputs of the detector and the reference sound information stored. On the basis of the calculated pattern distances and the equi-pattern-distance curves, the position of the unknown sound source is determined. On the basis of the position of the unknown sound source, kinetic energy thereof may be arithmetically determined.

摘要： Method and apparatus for estimating the location of an unknown sound source (B) in a structure (1) to be monitored, wherein sounds from at least three known sound sources (A i ) are detected by a plurality of detectors (S). At least one of peak value data and signal arrival time data derived from the outputs of the detectors (S) are classified for each of the known sound sources (A i ) and stored in a storage (191). Pattern distances from each of the known sound sources to a number of predetermined position (A i ) respectively, are calculated to prepare for each of the known sound sources a correspondence table indicating relationships between the calculated pattern distance and real distances from the known sound source positions to the predetermined positions, the correspondence table being stored in a storage (192). The pattern distances for each of the known sound source positions are calculated on the basis of the sound signal data derived through detection of a sound from an unknown sound source and the data stored in the storage. The real distances each for the known sound source are read out from the correspondence table on the basis of the calculated pattern distances and displayed on a display device to thereby estimate the location of the unknown sound source.

摘要： A system for discriminating radiation-contaminated fragements (1) on the basis of a predetermined radioactive concentration includes a detection device (7) for detecting the radiation of the fragments (1), the detection device (7) having a path (88) of transfer of the fragments (1), at least one radiation detector (2) disposed at one of the inside and outside of said transfer path (88), and a transfer device (83; 90; 98) for sequentially transferring the fragments (1) in the transfer path (88); a convey device (42) for conveying the fragments (1) to said detection device (7); and a controller (100) for determining the radioactive concentration of the fragments (1) in accordance with the radiation detected by the detection device (7) and for judging whether or not the radioactive concentration of the fragments (1) is the predetermined radioactive concentration. The controller (100) is also operable to control the transfer device (83; 90; 95; 98) so as to adjust the speed of transfer of the fragments (1) in the transfer path (88). The system further includes a density detecting device (39) for detecting the density of the fragments (1) to be conveyed to the detection device (7). The controller (100) corrects the above determined radioactive concentration by the density detected by the density detecting device (39).
