  • Patent number: 7404692
    Abstract: Waves are amplified by a gradual decrease in depth, and when the waves reach a vertical wall 10 of a reef 2, breaking waves are generated by sudden decrease of the water depth. As the breaking waves rush into the upper portion of the reef 2 and pass through the slant slits 14, wave energy is absorbed by the reef 2 and the seat water returns back to the ocean through an opening 11. The sand brought into a reef 2 with the waves are washed away by the return flow 11 so that the sand is not deposited within the reef 2 and the space in the reef 2 is always clear. The return flow promotes generation of the breaking waves. The breaking waves are introduced into the slits, beach erosion is prevented, and a calm sea area utilized for marine leisure is created. The seawater in the reef, with sufficient air, flows to the sea area behind the breakwater through the paths 19.

  • Patent number: 6233880
    Abstract: A deployable structure comprising a side wall having a plurality of segments which make the side wall a tube-like shape as a whole. Four adjacent segments are connected with one another at one point to make one module. The folding patterns of the segments along the connecting creases have two purposes, one of which is a closing pattern to reduce an inner angle between connected segments adjacent in a circumferential direction of the side wall, accompanied with a folding in a direction of a central axis, the other of which is an opening pattern to enlarge the inner angle between connected segments adjacent in the circumferential direction of the side wall, accompanied with a folding in the direction of the central axis. As a result the side wall can be deployed and packaged in both directions of the central axis and the radius of the side wall by folding the segments along the connecting creases thereof in the closing and opening patterns.
