Abstract: An air compression apparatus which can be used without requiring power supply equipment, including: a cylindrical body; an impeller which is provided inside the cylindrical body; a rotary shaft provided to be rotatable coaxially with the impeller; a cylindrical casing accommodating a part of the rotary shaft; a rotation transmission mechanism that transmits the rotation of the impeller to the rotary shaft while increasing the rotation speed of the rotary shaft; a piston connected via a crank unit to the rotary shaft housed in the casing; a cylinder provided on the outer peripheral wall of the casing; an introduction unit provided in a cylinder for introducing air into the cylinder; and a discharge pipe each connected to the cylinder for discharging a compressed air compressed by the piston inside the cylinder. Therefore, it is possible to provide an air compression apparatus which can be used without requiring power supply equipment.

Abstract: This invention is to provide structural member joints capable of easily reinforcing connecting portions of structural members and a structure using the structural member joints. Each structural member joint includes three tubular joint members into which end portions of the structural members 7 can be inserted and fixed. The three tubular joint members are connected to each other at their proximal end portions and disposed at right angles to each other. Since the distal end portions of the joint members 2 arranged at right angles to each other are connected by the reinforcing members 6, it is possible to use the reinforcing members 6 to easily reinforce the connecting portions of the structural members 7.

Abstract: A wind rotating apparatus capable of efficiently generating electric power even in the case of slight wind or the like, and a wind power generator equipped with wind rotating apparatus. Wind rotating apparatus includes: wind collection unit for introducing wind through inlet port, collecting and discharging wind through outlet port; sirocco fan which rotates about an axis by virtue of air discharged from outlet port of wind collection unit; rotary shaft provided coaxially with sirocco fan; planetary gear mechanism for transmitting rotation of sirocco fan to rotary shaft while increasing its rotation speed. Since a permanent magnet is provided on rotary shaft and coil is provided on lower casing, even if rotation speed of sirocco fan is low in the case of slight wind or the like, rotation speed of rotatary shaft can still be increased.

Abstract: The wind collection apparatus has a wind collecting section for collecting wind taken from a front surface side into a wind outlet. The wind outlet is provided below an upper end of the front surface of the wind collecting section. The wind collecting section is configured such that a cross section of wind flow passage becomes smaller from the front surface side toward the rear surface side. The wind collecting section has a pair of left and right side wall portions, and an upper wall portion bridged between the pair of side wall portions. A plurality of support columns are arranged to penetrate the upper wall portion. The upper end portion of each support column and the upper wall portion are connected to each other by cables, and upper wall portion is suspended by the cables.
