摘要： PURPOSE:To obtain a supply and recovery mechanism for a contacting medium which is indepedent of an inspection device by supplying and collecting the contacting medium from the tube end flange part of a small-diameter tube by a supply device and a recovery device which are independent. CONSTITUTION:An ultrasonic probe 6 is fitted to a flaw detection head 7 and coupled with a driving device 9 through a rod 8. A flange 10 where a hole for supplying the contacting medium is formed is fitted below a housing flange 5. A packing 11 for sealing is fitted in the flange 10 to prevent the contacting medium from leaking. Then the contacting medium supply device 14 sends the contacting medium to the flange 10 to fill a neutron flux detector housing 3. A supply valve 15 is closed when the supply device 14 is stopped to prevent the contacting medium from flowing backward. When the contacting medium becomes unnecessary, the contacting medium recovery device 16 opens a recovery valve 17 to collect the contacting medium.

摘要： PURPOSE:To control automatically molten slag to an optimum depth and to enable full automation of electroslag welding by comparing the depth of the molten slag detected by utilizing ultrasonic vibrators and optimum depth and controlling the amt. of the flux to be charged. CONSTITUTION:The surface and depth of molten slag 3 are detected by utilizing plural pieces of ultrasonic vibrators 11 arranged on the side of a sliding partition plate 8 for the slag 3 on the side opposite from the slag 3. The detected depth and the preset optimum depth are compared. The amt. of the flux to be charged is caluclated from the deviation thereof and a control device 6 for charging the flux is controlled according to the calculated amt. The control quan tity of the plate 8 is calculated frm the surface of the slag 3 detected in the above-mentioned way. A device 10 for driving the plate 8 is controlled according to the calculated value, by which the slag is automatically controlled to the optimum depth.

摘要： PURPOSE: To perform the surface flaw inspection of a machined component which is mass-produced without providing any special inspecting process by adding a high-brightness fluorescent material to cutting fluid, and irradiating it with ultraviolet rays after cleaning and making an observation.
CONSTITUTION: A component to be machine is cut in a machining process S
1 while applied with the cutting fluid. Then, the fluorescent material which fluoresces when irradiated with ultraviolet rays is added to the cutting fluid, and then if the component has a surface flaw, the cutting fluid containing the fluorescent material penetrates the flaw and also sticks on the surface. Further, the cutting fluid sticking on the surface is removed in the cleaning process S
2 after the machining, but the cutting fluid in the flaw remains unless a special cleaning process is performed. The fluid is irradiated with ultraviolet rays in an inspecting process S
3 , and then the cutting fluid remaining in the flaw fluoresces, so the surface flaw is easily inspected. Further, no special processing is required for the inspection, so this is suitable to the quality control over machined components, such as bolts and pipe joint, which are mass-produced.

摘要翻译：目的：通过向切削液中添加高亮度荧光体而进行大量生产的加工部件的表面缺陷检查而不进行特殊检查，并在清洗后进行紫外线照射。构成：在加工切削液的同时，在机械加工S1中切割要成形的部件。然后，将通过紫外线照射发荧光的荧光物质添加到切削液中，然后如果该部件具有表面缺陷，则含有荧光材料的切削液渗入该缺陷并粘附在该表面上。此外，在机械加工之后，在清洗工序S2中去除粘附在表面上的切削液，但是除非进行特殊的清洗处理，否则缺陷中的切削液保持不动。在检查过程S3中用紫外线照射流体，然后残留在缺陷中的切削液发荧光，因此容易检查表面缺陷。此外，检查不需要特殊的处理，因此适合于大量生产的诸如螺栓和管接头的加工部件的质量控制。

摘要： PURPOSE:To carry out all test processes by single-time insertion by assembling treating devices, which are required for a preprocess, a penetration process, a cleaning process, and a drying process, in one insert rod in one body. CONSTITUTION:A solvent of cleaning liquid supplied from a feeding pipe 73 is blown to a test surface of a tube 61 to be tested by a preprocess nozzle 11 to remove foreign matter and the test surface is dried with a hot blast from a dry air nozzle 31. Then a penetrant spraying nozzle 21 blows a penetrant to the test surface of the tube 61 to be tested and the penetrant penetrates a material flaw. Then water is blown by a cleaning spraying nozzle 12 to flush and remove an excessive penetrant on the test surface other than the penetrant in the material flow. The treating devices which are necessary for those processes are assembled in the one insert rod 51 integrally. Then the series of processes can be performed by inserting the rod into a test unit 100 only once and the device is applicable even to a narrow part.

摘要： PURPOSE:To use effectively an image integrating processing apparatus, by, in a control system using the image integrating processing system, silencing quantizing noise and improving image clearness. CONSTITUTION:An image control apparatus 13 controls filter adjustor 14, light image intensifier adjustor 15 and X-ray adjustor 16. Further, when an X-ray penetration image of monitor TV 10 is brightened with halation, X-ray control volage and current is dropped by the adjustor 16. By this, X-ray energy to an X-ray penetration camera 3 is limited to a small value for silencing the quantizing noise. Further, by adjusting filter 6 and light image intensifier 8 by adjustors 14, 15, the clearness of image is improved. Thus, as the quantizing noise can further be silenced, effective use of the image integrating processing apparatus 11 can be achieved.

摘要： PURPOSE:To improve the degree of identification of defect by moving an incident image to a solid-state image pickup element so as to reduce quantized noise and improve the contrast of a picture. CONSTITUTION:When a dynamic picture input 18 is obtained by moving a fluoroscopic picture input 17 displayed on a picture element 16 of a solid-state image pickup element 12, a large current flows just after the movement and a dynamic picture input 18 is emphasized, the contrast of the picture is increased and the degree of identification of defect is improved. Further, in moving the incident image to the solid-state image pickup element 12, the quantized noise generated at random is averaged and a quantized noise spike at random is eliminated in the dynamic picture input 18 so as to improve the contrast of picture.
