摘要： PROBLEM TO BE SOLVED: To remotely and easily identify the component or the like of an object member with high accuracy without directly touching it with hands or approaching it by identifying the object member by irradiating that object member with light and detecting reflected light. SOLUTION: Radiation light is outputted from two light emitting diode flood instruments 4a and 4b and a marking area 3 on the surface of an object member 2 is irradiated with that light. The reflected light reflected by the marking area 3 is converged by a lens 5a and narrowed by a diaphragm member 5b and afterwards, the image of marking 3 is formed on a photoelectric transducing plane 6a of a CCD image sensor 6. The sampling of reflected light due to an optical system 5 for sampling is performed out of the direction of regular reflection (mirror reflection direction). Then, difference is generated between the quantity of detected light diffused and reflected from the smooth area of marking area 3 and the quantity of detected light diffused and reflected from the rough area. A data processor 7 can discriminate this difference and remotely read the marking 3 corresponding to the difference in roughness on the surface.

摘要： PURPOSE:To judge the timing to start the precision inspection of a member to be diagnosed so that the deterioration thereof can be diagnosed early by measuring the size of the initial microdefects, such as atom holes and lattice defects, existing internally in the member and the change in the density thereof. CONSTITUTION:For example, test pieces consisting of the same material as the member to be diagnosed are used and the initial defects of the atomic and molecular levels in the test pieces or the sizes of the expanded defects and the concn. are measured by a positron life measuring method. On the other hand, the same test pieces are subjected to destructive inspections, such as fatigue tests and acceleration test, etc., to obtain the relations between the growing speeds of the defects and the time when the defects grow to about several 10 to several 100 mum defects which can be detected by ordinary nondestructive inspections as well as the sizes of the defects. Namely, the changes are measured in accordance with the life diagnosis chart indicting the relations between the size and density of the defects and the expanding progression of the defects by which the initial defects existing internally in the member to be diagnosed are expanded and the service time of the member until the ordinary nondestructive inspections become effective is derived. Thus, the deterioration of the member is diagnosed in an early period.

摘要： PURPOSE:To enable a substantial saving of time and labor required for an inspection by collecting an inert gas discharged from a failed nuclear fuel element, by measuring and analyzing a mass to electric charge ratio (m/e) of the gas. CONSTITUTION:A device in this invention is composed of an inert gas collector 12, an inert gas analyzer 13 and a radioactivity detector. As a Kr (krypton 80) which is a stable isotope of Kr (krypton) is sealed into a nuclear fuel element as a part of the inert gas, an amount of the Kr discharged from the fuel element and a discharged amount of Kr which is produced by the Kr absorbing a neutron are measured when a clad tube of the nuclear fuel element is failed. Furthermore, by obtaining a ratio to a discharged amount of a Kr being generated as a fission product of the fuel, a burnup of the failed nuclear fuel element can be estimated and therewith a time for identifying a fuel assembly that contains the failed fuel element can be substantially shortened.

摘要： PROBLEM TO BE SOLVED: To introduce a microcrack into the surface of a brittle member with high accuracy. SOLUTION: A laser light 50 oscillated from a laser oscillator 10 is emitted to the surface of a brittle material 60 covered with a liquid 52 via an optical fiber 18, a lens 20 or the like. At this time, the distance d between the lens 20 and the surface of the brittle material 60 is adjusted, and the laser light 50 at the emission edge face of the optical fiber 18 is imaged at the surface of the brittle material 60. Then, the circumferential part in which the output density of the laser light 50 has been raised is emitted to a desired surface part of the brittle material 60. COPYRIGHT: (C)2011,JPO&INPIT
