Abstract: An I/O card assembly (1) is provided having an insulative frame means (10, 40) sandwiched by a pair of generally similar conductive covers (50, 70). Each cover (50) includes a main plate (52) and two elongated side shielding walls (56) downward extending from two opposite sides of the plate (52) a first distance which is generally half of a height of the side wall (12) of the frame (10). A groove (18) horizontally extends along the center line of side wall (12) of the frame (10) for receiving both the hook sections (58) which are respectively inwardly formed at the outermost edges of the side shielding walls (56) of the top and the bottom covers (50, 70).

Abstract: The present invention is related to an improved wind turbine particularly with the provision of a strengthened network axle pivoted upon an elevated lattice steel tower; and a few upper and lower rotor arms horizontally fixed onto said strengthened network axle--respectively onto upper portion and lower portion thereof; and a few blades which, being V shaped in cross section, are provided between said upper and lower rotor arms; and a transmission mechanism; being thus constructed that wind power is liable to be converted into mechanical power therefrom.
