摘要： PROBLEM TO BE SOLVED: To mix hot water with cold water satisfactorily when hot water is flown reversely in an inner pipe so as to prevent a large thermal stress from occurring by providing spiral projections on the inner surface of the inner pipe in a double pipe nozzle in which the container inner side of a nozzle which passes through the container is doubled and feeds water from the inner pipe into the container. SOLUTION: A water feed nozzle 2 is constructed in a double pipe structure of a nozzle main body 2a connected integrally with a pressure vessel 1 by welding and an inner pipe 3 through which low temperature water is fed from a water feed pump 7 through a valve 6. Also a ring-shaped spur jar 4 with multiple blow ports 5 is installed in the inner tube 3 on the pressure vessel 1 side, and a spiral projection 8 is installed on the inner surface of the inner pipe 3 on the spur jar 4 side. By this, when hot water inside the pressure vessel 1 is flown reversely from the blowing ports 5 to the inner pipe 3 in such a case that feed water amount is reduced, hot fluid is circulated by spiral projections 8, and mixed with low temperature water inside the inner pipe 3 so as to reduce the temperature. Thus a large amount of thermal stress is avoided from occurring.

摘要： PROBLEM TO BE SOLVED: To effectively damp vibration of a valve such as fluid vibration by simply constructing a device to be easily mounted on a valve. SOLUTION: A mounting table 65 with a vibration damping mechanism 71 for damping vibration in one direction is mounted on a valve rod drive part 57 at the end of a valve rod by using a connection fixing device 63 which is subjected to vibration damping by the vibration damping mechanism 71 in a direction perpendicular to an axis 64 of the valve rod 55 and can be fixed to a selective rotation position with the axis 64 of the valve rod 55 as a center. The vibrating direction of the valve 51 is detected, the detected vibrating direction of the valve 51 is made to correspond to the vibration damping direction of the vibration damping mechanism 71 and the mounting table 65 is fixed to the valve rod drive part 57 at the end of the valve rod by using the connection fixing device 63, thus suppressing the vibration of the valve 51 with the vibration damping mechanism 71 whose vibration damping direction corresponds thereto.

摘要： PROBLEM TO BE SOLVED: To prevent generation of vibration noise, and improve durability of vibration suppression location by putting a vibration absorber between a bellows and a support ring. SOLUTION: Between a support ring 12 supporting a distortion suppression ring 11 inserted in an outward groove Ha of a penetration bellows H and the outward groove Ha, a vibration absorber 13 of the same material as the bellows H is arranged in interfacing state. When the inner pressure is impressed on the bellows H and the outward groove Ha diameter is expanded, the ring 11 suppresses the displacement of the bellows in a tolerable range. When vibration is transmitted to the bellows II, however, the absorber 13 displaces to suppress the transmission of the vibration from the bellows H to the ring 12 and mitigate shock and so the abrasion phenomenon and generation of vibration sound are prevented. Furthermore, as the absorber 13 absorbs the vibration energy and attenuates it during displacing, the vibration of the bellows H is suppressed. Thus, abrasion of the bellows H and generation of metal fatigue are suppressed and durability is improved.

摘要： PROBLEM TO BE SOLVED: To reduce vibration and noises caused by a rotating apparatus, by arranging a laminated vibration proof body in the axial direction of an input/output shaft, between the lower part of an upper floor member on which the rotating apparatus in a steel building is arranged and a lower floor member. SOLUTION: A laminated vibration proof body 22 comprising in a manner that vibration proof members 21 comprising vibration proof gel and the like consisting of vibration proof rubber and silicon as a main component, and steel plates 23, are alternatively laminated in an axial direction 19 of rotating apparatuses 10, 12, is interposed between both supporting frames 16, 20 attached between a lower part in a position where the rotating apparatuses 10, 12 on an upper floor member 7 composing the floor of a steel building 1, and a lower floor member 8. This laminated vibration proof body 22 has about 1/100 rigidity to a laminating direction and a transverse direction, which is small in comparison with rigidity to the laminating direction. Therefore, when a floor intends to vibrate by the vibration of the rotating apparatuses 10, 12, the laminated vibration proof body 22 is shorn and deformed in the laminating direction and transverse direction thereby, the vibration of the floor is absorbed so as to reduce the vibration of the floor, and also noises caused by vibration can be also reduced.

摘要： PROBLEM TO BE SOLVED: To efficiently cool glass solid body by putting a heat conduction member in between glass solid bodies and constituting so as to make its tip end contact the inner surface of a container tube. SOLUTION: Between canisters 20 and 20' contained in a container tube 11, a heat conduction member 30 is put in. The heat conduction member 30 is formed with a thickness capable of easily being bent by the weight of the canister by a stuff with high heat conductivity such as copper. The heat conduction member 30 is contacted and fixed in the state that its central bend part is fit in the recess part 22A at the bottom 22 of the canister 20, put in between the canisters 20 and 20' so that its arm part 31 is pinched between the bottom 22 of the canister 20 and the upper surface of the canister 20' and horizontally bent, and in the state that its tip end 31A touches the inner surface of the container tube 11. By constituting in this manner, the heat from the canisters 20 and 20' efficiently transmits in the containing tube 11 by conduction through the heat conduction member 30 and is radiated in the air in the ventilation path 13 in between the containing tube 11 and the ventilation tube 12.

摘要： PROBLEM TO BE SOLVED: To prevent deformation of a hatch member caused by deformation of a peripheral wall of a cylindrical pressure vessel, and prevent the deterioration of sealing performance with a door member by arranging and constituting a reinforcing member continuing in its circumferential direction on the outer periphery of an opening end part on the opposite side of an end part where the door member of the hatch member is arranged. SOLUTION: When internal pressure of a pressure vessel 1 increases, a cross- sectional circular hatch member 20 is pulled by double force in the circumferential direction to the direction in parallel to the central axis of the pressure vessel 1 according to its pressure increase. As a result, though it tends to deform in an elliptic shape whose circumferential direction is set as the major axis, a reinforcing ring 40 resists this deformation, and prevents deformation of a hatch member 20 into an elliptic shape, and restains a diametrical change very small. Therefore, pressure contact sealing part of the hatch member 20 is prevented from being displaced large in the radial direction to a door member 30 whose diameter does not change even by an increase in internal pressure, and sealing performance is held.
