摘要： PURPOSE:To make it possible to continuously and automatically perform the flaw detection of a stud bolt with good efficiency, by attaching a plurality of stud bolts to the periphery of a support in a detachable manner and holding a probe to the arm revolving around the support. CONSTITUTION:A plurality of receiving stands are provided on the circle of circumference around a support 4 on a base plate and stud bolts 5 for clamping the lid of the vessel of an atomic reactor are provided to said receiving stands in a detachable manner. A support stand 15 is attached to the support 4 and an arm 21 is attached to the support 4 so as to be rotated around said support 4. A rack 40 moving up and down through a guide 27 is attached to the leading end of the arm 21 and an ultrasonic probe 43 is attached to the lower end of the rack 40. The probe 43 is successively driven by pulse motors 19, 31 to continuously perform flaw detection.
摘要翻译：目的：为了能够以高效率连续自动地执行双头螺栓的缺陷检测，通过将多个双头螺栓以可拆卸的方式安装到支撑件的周边并将探头保持在围绕支撑件旋转的臂上。构成：在基板上的支撑体4周围的圆周上设置有多个接收台，并且以可拆卸的方式将用于夹紧原子反应堆的容器的盖的双头螺栓5提供给所述接收台。支撑架15附接到支撑件4上，并且臂21被附接到支撑件4上以围绕所述支撑件4旋转。通过引导件27上下移动的齿条40被附接到臂的前端 21，超声波探头43安装在齿条40的下端。探头43由脉冲电动机19,31依次驱动，以连续进行缺陷检测。

摘要： PURPOSE:To expands an observation range by positioning a light guide at both ends of an image guide, and setting the sideway view part of the image guide and projection parts of two light guides in the same direction at the same position along a probe. CONSTITUTION:One image guide and two light guides l are put together, all guides are arrayed laterally as to the tip probe 1, and the light guides l are positioned at both sides of the image guide (i). Then, the sideway view part of the image guide (i) and the projection parts of the two light guides are set at the same position in the same direction along the probe 1. When a fuel rod (b) is observed, light from the image guides l and l is projected to the distance between the probe and a fuel rod surface, i.e. nearly overall visual field width (w) of the image guide (i) at observation distance DELTAh (

摘要： PURPOSE:To perform high-precision measurement by sticking a strain gauge to the bottom of a channel-shaped elastically deformed plate which has the bottom part thinner than other parts, and making a scan while allowing both end parts of the deformed plate to abut on the internal surface of a tube to be checked. CONSTITUTION:To the bottom part 56 of the channel-shaped elastically deformed plate 50 having the bottom part 56 thinner than other parts, the strain gauge 57 is stuck and at both end parts of the deformed plate, bearings 53 abutting on the internal surface of the tube T to be checked are provided. Coupling rings 61 and 64, on the other hand, retrain the displacement of the deformed plate 50 in the axial directions of the tube T to be checked and allow the bearings 53 to be displaced freely at right angles to the surface of the tube T, and a feed shaft 60 is connected to the coupling rings 61 and 64 through universal joints 62 and 63. Further, a means for feeding the feed shaft 60 in axial and rotational directions and a means for detecting the extents of axial feeding and the extent of rotation are provided.
