A floating structure, such as a mooring buoy, moored to the seabed via anchor lines that comprise an anchor line section which is stretchable in its length direction, such as a polyester line. An apparent shape of the solid-state image pickup device viewed from a front surface side of the body mount is a rectangle in which one or more corners are oblique. The materials can be assembled in a continuous manufacturing process. A related invention is a mobile personal scent device or Mobile ScentDEV, comprising mechanical, electro-mechanical, or electrical user controls.
