Abstract: Provided with a power generator and a power generation method capable of generating electricity using water of river or the like with a simple facility without using large facilities required in a conventional hydroelectric power plant. A buoyancy power generator includes: a storage tank which is capable of storing water; an inlet port from which the water is introduced into the storage tank; an outlet port from which the water is discharged from the storage tank to an outside; an opening and closing mechanism for opening and closing the outlet port; a floating body arranged in the storage tank so as to be vertically movable; and a power generator configured to convert a vertical motion of the floating body into electricity. A buoyancy power generation method using the above described power generator.

Abstract: A reinforcing structure for a wooden building, having: a first anchor bolt that is horizontally inserted into a concrete foundation of the wooden building and fixed to the concrete foundation by an adhesive agent; a second anchor bolt that is horizontally inserted into a wooden beam of the wooden building and fixed to the wooden beam by the adhesive agent; a reinforcing steel bar that is arranged between the first anchor bolt and the second anchor bolt; a first fixing member that connects and fixes the first anchor bolt and the reinforcing steel bar with each other so that the first anchor bolt and the reinforcing steel bar are orthogonal to each other; and a second fixing member that connects and fixes the second anchor bolt and the reinforcing steel bar with each other so that the second anchor bolt and the reinforcing steel bar are orthogonal to each other.
