摘要： PROBLEM TO BE SOLVED: To enable a high-power operation and enhance safety of a battery.
SOLUTION: A safety tube 12 can be prevented from being directly contacted to a beta-alumina tube 1 by providing a positioning spacer 14 at least at one place at the beta-alumina tube 1, so that an area in which a gap width 11 becomes extremely wide can be decreased, and a momentary direct reaction amount is suppressed. A subsequent sodium flow amount to a direct reaction area can be reduced by pressure control in the safety tube 12 and a vessel or by a reduction in a sodium supplying hole diameter 8, and the safety is increased in such a manner that a differential pressure between a sodium pole 6 and a sulfur pole 5 is controlled and the direct reaction is limited to the sulfur pole 5 and especially to a gap portion. Furthermore, since a sodium flow is not interrupted due to a direct contact of the safety tube 12 to the beta-alumina tube 1, it becomes possible to flow a large current and perform the high-power operation.

摘要： PROBLEM TO BE SOLVED: To provide a residual stress improving method of efficiently generating cavitations in a material surface when a WJP (water-jet peening) is applied to the material surface, and a device for use in the method, and to provide a residual stress improving method for reducing corrosion of the material surface which is fractured by impact pressure at the time of collapse of cavitation bubbles when the WJP is applied to the material surface, and a device for use in the method. SOLUTION: According to the material surface treatment method, magnetized water is ejected from a jet nozzle 2 to the surface of a material 14, and by using the impact pressure generated by the collapse of the cavitation bubbles accompanying the magnetized water, the compressed residual stress is applied to the material. Thus when the WJP is applied to the material surface, the cavitations are efficiently generated on the surface. Further when the WJP is applied to the material surface, the corrosion of the material surface fractured by the impact pressure generated at the time of the collapse of the cavitation bubbles, can be reduced.
