An anti-earthquake bearing apparatus for bearing the weight of a structure and reducing the vibration energy propagating to the structure by using bearing bodies disposed between the structure and a foundation or another structure has spherical bag-like bearing bodies serving as said bearing bodies formed by sealing a fluid, rubber-like solid or gas into bags constituted by a rubber-sheet material reinforced with fiber. Each bag-like bearing body is provided with charging/discharging ports. Recesses for preventing positional shift of said bag-like bearing bodies are formed on the bottom surface of the structure and on the upper surface of the foundation.

Anti-earthquake bearing apparatus

A floating cargo hose for transporting fluid from a vessel having an excellent abrasion resistance and a unique distinct color of colored urethane is manufactured by wrapping a hose body in which is embedded a fibrous sheet or a spiral wire in rubber with a sponge layer having closed cells, covering the sponge layer with a first rubber cover in which is embedded a fibrous sheet and vulcanizing the rubber, treating the first rubber cover to promote adhesion and coating the thus treated first rubber cover with a liquid urethane rubber and curing the liquid urethane rubber to form a second cover.
