Abstract: A vertical axial wind power generator including blades rotated in a horizontal direction, and each blade includes inner and outer wind collection vanes, so that the blades can be operated without being limited by space and environment and can be rotated vertically by tiny wind. When wind power is lower than magnetic force of magnet on the blades and fastening disks, the blades enters an open status to increase windward area; when wind power is higher than the magnetic force, centrifugal force can force the blade to close to become a ball type, and blades of the ball type can have strong torsion effect, and only the windward area of the outer wind collection vane receive wind, so that rotation speed of the wind power generator can be stable. When wind power becomes weak, the blades can be rotated reversely to the open status.

Abstract: A manufacturing method for a composite material hand tool. Its long and short fiber layers filling is covered with a metal interface ring at one side. The handle can be encircled into a cone shape. A center layer can be a short fiber honeycomb layer. The outer layer is coated with a long fiber. It is a torque wrench made from composite material. Its characteristic includes base composite material, interface ring, internal wall of tooth surface, and exterior of projected rib. Bearing resistance is at the adjacent through hole of the interior wall of tooth surface and the reciprocal commutating tooth surface. The exterior of the projected rib is at the side contacting with the base composite material of the wrench.
