摘要： PROBLEM TO BE SOLVED: To prevent a flaw detection result from being affected by the shape of the crack of a pipe, to accurately evaluate the degree of flaw detection of the crack, and improve reliability. SOLUTION: When an ultrasonic wave from the outer-periphery surface of a pipe 1 is given into a pipe and the crack of a pipe is subjected to flaw detection, the echo height of the ultrasonic wave being reflected by the crack of the pipe is measured by oblique probes (an axial oblique probe 3, a circumferential oblique probe 3a, and a vertical oblique probe 3b). Then, the repetition count of the ultrasonic wave being reflected by the crack is measured by the vertical oblique probe 3b, and the echo height and the repetition count of the ultrasonic wave are allowed to correspond each other for detecting the damage of the pipe 1.

摘要： PROBLEM TO BE SOLVED: To prevents leaks from an injection hole to achieve high performance and a long life by using an alumina sintered body as a positive active material injection pipe, and hermetically sealing its injection hole with glass. SOLUTION: An α-alumina pellet 1, a tungsten positive terminal bar 2', and an α-alumina positive active material injection pipe 15 are glass joined together at junctions 3, 3'. Next, the pellet 1 is joined to a β"-alumina tube 4 at a junction 5. The glass joining is performed with glass blazing filler metal used at the junctions 3, 3', 5 to obtain high airtightness. An α-alumina lid 16 is put on the upper injection hole of the injection pie 15, and glass blazing filler metal 17 for sealing the injection pipe is packed over it in powder form. To join the blazing filler metal 17, heating of only the blazing filler metal 17 should be taken into account since a positive active material, sodium, and the junctions 3, 3', 5 joined together exist inside the battery. By forming the injection pipe 15 from α-alumina that conforms to the blazing filler metal 17, the airtightness and durability of a sealed portion are enhanced, and then performance degradation will not occur even in a long period of operation exceeding 300 charge- discharge cycles.
