摘要： PURPOSE:To record an effective detect signal out of sound detecting elements which are more in number than input channels, in accordance with locations where loose parts are generated, by recording output signals of sound detecting elements which are decided by the content of input signals to a storing device. CONSTITUTION:When output signals a1-an of(n) pieces of sound detecting elements are supplied to a signal selector 2 as the input, and an external signal(c)is supplied to an ROM1 whose signal ratio of input//output is 1:1, a signal (d) is read, and, based on the content of the signal (d), a part signals b1-bm out of the signals a1-an are recorded in a recording device 3. Therefore, it is possible to correlate contents 1 -n of the input signal (c) to the ROM1 with detect channels for loose parts, and to selectively record signals from sound detecting elements near the loose parts in accordance with the detected channels for loose parts.

摘要： PURPOSE: To detect the lowering of function of a foreign matter detecting apparatus, by producing a shock sound forcibly on a housing of a nuclear reactor pressure receptacle or a vapor generator by a shock giving instrument and comparing this shock sound with the characteristic of preliminarily memorized shock sound. CONSTITUTION:Shock sounds are produced by operating shock giving instruments 81-8n and these shock sounds are detected by sound detectors 31-3n. The detected waveform is analyzed by a characteristic extractor 9 provided with a microcomputer and the analyzed results are compared with the comparison data of shock given on the same place and then, whether there is a difference more than the set value or not is examined. If anything unusual occurs in a course from the sensor 3 to a filter 5, the detected signal of an abnormal detection system is varied to a low crest value. Also, the variation of the same tendency appears on the whole detected signal if there is anything unusual about the instruments 81-8n.

摘要： PURPOSE:To locate the loose parts accurately by a method wherein the relative crest value and the relative time gap are determined for each detector from the detection signals obtained at plural detectors, and the two kinds of measurements thus determined are combined so as to locate the loose parts. CONSTITUTION:The signal from each detector is fed into a time gap measuring device 5 and a relative crest value measuring device 6. The time gap measuring device 5 determines the time at which each detector detects the signal, utilizing as a reference the time at which the first-arriving detection signal was detected by the detector. The relative crest value measuring device 6 determins the relative crest value of the peak appearing in the detection signal obtained at each detector, taking as the maximum crest value the largest one of the peaks in the detection signals obtained at the detectors. A display unit 7 display the distribution pattern for each detector on a coordinate system of the relative crest value and the time gap, utilizing the relative values and the time gaps obtained for each detector. Based on the displayed results, the operator recognizes the locations of the loose parts.
