摘要： PURPOSE:To prevent the concentration of stress and the generation of a crack, by providing circular annular hollow rings so as to be placed along the internal wall of ring space formed in the periphery of a fitting surface in a flange part. CONSTITUTION:A valve case of a valve is integrally formed by a valve cover 3 and a bolt through a flange 2. A ring 21 of J-shaped section, protruding to the upper, is provided in the whole periphery in the upper surface of the flange 2. While a ring 22 of 7-shaped section, protruding to the bottom, is provided placing its point end to be opposed to the point end of the ring 21 in the whole periphery in the bottom surface of the cover 3. Circular annular space 20, formed by the J-shaped rings 21, 22, provides a circular annular hollow ring 12 of C-shaped section to be placed along the internal wall. When butt welding is performed in end parts of the J-shaped rings 21, 22, an edge preparation point end is melted being integrally formed, simultaneously also the circular annular hollow ring 12 is locally welded. Accordingly, the flange 2, eliminating a protruding part to an internal surface side, enables the generation of a crack and a break, caused by the concentration of excessive stress, to be prevented.

摘要： PURPOSE:To prevent force applied to a solid electrolyte tube even if thermal deformation is caused when a temperature of a positive electrode structure body is lowered as well as to avoid breakage of the electrolyte tube by setting a ratio of linear expansion coefficients in a radial direction and a circumferential direction of the positive electrode structure body in a battery three times or larger than that. CONSTITUTION:A sodium - sulfur battery is composed of a negative electrode active material 1 composed of fused sodium, a solid electrolyte tube 2 composed of beta''-alumina to surround this and a positive electrode structure body 3 composed of carbon fiber felt being an electrical conductive body 7 and sulfur 8 being a positive electrode active material. In this constitution, assuming that a linear expansion coefficient K of felt turning in a radial direction and a circumferential direction in the structure body 3 is set in (K=3) or (K>3), the fact that linear expansion coefficients of the structure body 3 and the electrolyte tube 2 become the same speed when (K=3) is realized and the linear expansion coefficients become mutually separating speed when (K>3) is realized, can be proved. Thereby, the K is set in (K=3) or (K>3), and the sulfur 8 is melted when a battery temperature is raised, and a compressive condition of the felt is released, and the sulfur 8 is solidified when it is lowered, and the structure body 3 is contracted while increasing strength.

摘要： PURPOSE:To obtain high vibration resistance by providing a means to reduce the gap between a pipe and a U-bolt, and nearing the portion brought into contact with a saddle onto a center axis in a supporting device of the pipe provided with the frame of the pipe, saddle and U-bolt. CONSTITUTION:A frame 4 mounted with a pipe on it, a saddle 5A provided between the frame 4 and the pipe 1, and a U-bolt 2 fastened to the frame 4 over the pipe 1 to fix the pipe 1 to the frame 4 are provided. A means to reduce the gap (g) between the pipe 1 and the U-bolt 2 is provided, e.g., a loose hole 8 is bored on the frame 4, and it is adjusted by the movement of the fitting position of a plate 9. The portion of the saddle 5A brought into contact with the pipe 1 is arranged at the vicinity on the center axis passing the middle between the horizontal and vertical center axes of the pipe 1. As a result, support rigidity and load resistance are improved, and high vibration resistance is obtained.

摘要： PROBLEM TO BE SOLVED: To provide a sodium-leak preventive temperature gage which especially suitably prevents liquid sodium from being circulated in the temperature gage so as to be leaked to the outside regarding a sodium temperature gage which is installed at a piping facility in which the liquid sodium is circulated. SOLUTION: When a part situated inside a pipe at a well part 2 is damaged for some cause, liquid sodium inside the pipe is goint to creep into the well part 2. However, the liquid sodium does not creep to the side of a terminal housing part 7 from a bellows 11 at the inside of a nipple part 5. In addition, since a sodium detector 12 is installed in a position to the well part 2 from the bellows 11, the detector 12 detects the existence of the liquid sodium which creeps into the nipple part 5, a detection signal is transmitted via a circuit 13, and it is possible to find that sodium creeps into a temperature gage.

摘要： PROBLEM TO BE SOLVED: To measure the quantity of displacement due to a temperature change in a pipeline arranged in a restricted area, to read out the quantity of displacement at any time, and at the end of measurement, to display the maximum quantity of displacement obtained during the period of the measurement. SOLUTION: A pair of counters M1, M2 are arranged in parallel in a case C. A winding shaft 16 for energizing winding by a spring 18 is supported in the case C. One end of a wire 15a is pulled by a pulley 17 for the winding shaft 16 and the other end is locked to a case wall by a wire end piece 15a. This piece 15a and a pipe P are mutually connected in a tense state by a wire 15. The linear motion of the wire 15 due to the displacement of the pipe P is converted into the rotational motion of the counters M1, M2 through a gearing G. Even when a counter on the market is used for the counter M1 as it is, displacement can be read out at any time. Since a stopper is fixed to a numerical disc with the highest level and rotation only to one direction is allowed in the counter M2, maximum displacement can be displayed.
