Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To easily control the vibration by providing a sub cable and a sub hanger in a space below a bridge girder in a prescribed condition, and connecting the sub cable to the sub hanger through a viscoelastic damper. SOLUTION: A cylindrical viscoelastic damper 6 is fixed to a cable 5 stretched in the bridge axial direction at the center of a lower surface of a bridge girder 4, a sub hanger 7 is orthogonal to the cable 5, each end thereof is connected to each lower side part in the sectional direction of the bridge girder 4, and the tension of the cable 5 is supported through the damper 6 by the hanger 7. When the bridge girder 4 is moved to the position 8 by the torsional vibration, high tension is generated in the hanger 7 because the cable 5 is fixed, and the hanger 7 is displaced in the direction of the arrow 9 on the outer circumferential of a damper 6. The torsional deformation in the direction of the arrow 10 is generated in the damper 6 by the displacement, the torsional vibration energy is absorbed by the damper 6 and effectively dissipated.  The vibration can surely be damped by making use of the space below the bridge girder, and the wind-resistance design condition can be easily cleared without any time or labor.

Title: Valve device
Inventor: MIYAZAKI TETSUYA
IPC: F16K31/06
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent a valve body from self-excited vibration as well as to raise its controllability by making its action smooth. SOLUTION: The interior of a guide member 31 for a valve device 30 is provided with an inclined surface 39. A poppet valve 35 has a tapered inclined surface corresponding to the inclined surface 39. A contraction of area 43 is formed between inclined surfaces 42, 39 and gradually narrows the passage area where fluid passes through as the poppet valve 35 makes a valve opening action. Therefore valve opening action of the poppet valve 35 is smoothed and controllability of flow adjustment is raised because fluid resistance is weak at the contraction of area 43 where the poppet valve 35 opening is small and the flow rate is low.  Because the passage between inclined surfaces 42 and 39 becomes narrow as the poppet valve 35 acts towards valve opening, viscous resistance of the fluid passing through the contraction of area 43 gradually increases and self-excited vibration of the poppet valve 35 is restrained.
