  • Patent number: 8950362
    Abstract: An otter habitation section, an overland section, an inclined-surface section, a first spawning section, a second spawning section and a roost are all provided. Accordingly, otters and birds can sufficiently obtain preys, and fishes secure a spawning ground suitable for spawning characteristics. Therefore, the otters, the fishes and the birds can inhabit together. Further, since frames are made of wood for providing buoyant force or the frames are made of stainless steel for reinforcing strength and wood for providing buoyant force, a small amount of polyethylene foam is required. Accordingly, it is possible to obtain floating wetland equipment with a simple structure. Furthermore, the wooden frames itself provide a spawning ground of fishes.

  • Publication number: 20110120329
    Abstract: A method and apparatus for high-speed roll-to-roll printing, ensuring high-precision printing previously available only under a static condition. In the present invention, a pattern mask is wound on a print roll, and an ink injector and the roll are configured to maintain a substantially zero linear speed difference between the pattern mask and a print substrate at the moment the ink injector injects ink onto the print substrate through a perforated pattern in the pattern mask. The ink injector may be mounted on the print roll, may rotate separately from the rotating roll with a different rotational speed and direction, and may axially move to ensure no relative movement existing between the pattern mask and the substrate at the moment of printing. The roll may move linearly in the same direction as the substrate. A position sensor may be employed for more precise alignment between substrates in a multilayer printing.
