摘要： A structure of semiconductor radiation detector element having a p-n junction comprises a substrate layer (1) including a radiation absorbing layer having a silicon equivalent thickness (dʹ) not smaller than 140 µm and located adjacent to a depletion layer (5) formed at the p-n junction. With the simplified structure, both the detection sensitivity and the energy compensating performance are enhanced significantly.

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.
