摘要： PROBLEM TO BE SOLVED: To objectively judge whether an emulsifier is usable. SOLUTION: Penetration liquids various in concn. are premixed with an emulsifier to prepare standard solns. (step I) and the absorbancies of the standard solns. are measured (step III) and a calibration curve is formed from the absorbancies of the standard solns. (step III). The absorbancy of a sample of an emulsifier to be evaluated is measured (step IV) and applied to the calibration curve to calculate the concn. of the penetration liquid mixed with the sample (step V). On the basis of the calculated concn. of the penetration liquid, it is judged whether the emulsifier to be evaluatd is usable (step VI).

摘要： PROBLEM TO BE SOLVED: To provide a metal surface high-speed inspection device for speedily inspecting the defects of a continuous metal surface such as a railroad rail during running. SOLUTION: A device is provided with a fluorescent agent permeating device 12 that is installed on a vehicle 11, a UV pulse laser device 14 and an image pickup device 16, and an analytical device 18 for analyzing an image that is picked up by the image pickup device 16. The fluorescent agent permeation device 12 applies a fluorescent agent 2 to a metal surface 1a of an object 1 to be inspected, eliminates the fluorescent agent 2 adhering on the surface, applies a developing agent 3 to the surface, and allows the fluorescent agent 2 to remain only at a defective part. An ultraviolet pulse laser beam 5 with a wavelength of approximately 355 nm is applied to the metal surface, that is treated by the fluorescent agent permeation device 12 by the UV pulse laser device 14, the image of the metal surface is picked up in synchronization with the oscillation of the ultraviolet pulse laser beam by the image pickup device 16, and a fluorescent position (defective position) on the metal surface is detected by the analytical apparatus 18.

摘要： PROBLEM TO BE SOLVED: To efficiently and surely apply a flaw detect solution in a short time and improve a detect accuracy for cracks, by letting the flaw detect solution applied to a ceramics substrate penetrate a crack by a porous roller, then washing off the unwanted flaw detect solution, and drying the substrate. SOLUTION: While a ceramics substrate 1 is transferred by a transfer roller 14, a flaw detect solution 2 is supplied by a circulation pump 16 from a flaw detect solution tank 15 to a spray nozzle 5, sprayed and applied from above and below the substrate 1. A pair of porous rollers 8 are pressed from above and below the substrate 1 to rub the flaw detect solution 2 into a crack of the substrate 1. Then water is sprayed at a cleaning part B by a spray nozzle 6 from above and below the substrate 1, thereby washing out the extra flaw detect solution 2. Moisture on the surface of the substrate 1 is squeezed out by a porous moisture-removing roller 9. At a drying part C, the water remaining on the surface of the substrate 1 is removed by a moisture-removing roller 10, and air is sprayed from above and below the substrate 1 to remove the moisture remaining in holes and on the surface of the substrate 1. Hot wind is sprayed from the nozzle of a dryer 11 to have the substrate dried.
