Abstract: An anti-rotation locking nut (or bolt) is disclosed, including a nut (or bolt) body with a flange on the lower portion, wherein the under side of the nut (or bolt) body is ring-shaped with wavelike structures on the surface. The locking nut (or bolt) is used in conjunction with an anti-rotation packing fitted in between the article and the locking nut (or bolt). The cone shaped anti-rotation packing is formed with wavelike structures on the packing wall and made of compressible material having good elasticity. The wavelike structures on the under side of the locking nut (or bolt) and on the packing wall are to lock against each other to keep the locking nut (or bolt) in fixed position. The anti-rotation packing with the wavelike structures possesses good shock absorbing and cushioning effect to prevent the locking nut (or bolt) from inadvertent loosening.

Abstract: An expansion bolt includes a sleeve in which a central bore is defined, comprising a rear inner-threaded section and a front tapering section. Radial slits are defined in a front end portion of the sleeve and partially in communication with the tapering bore to form a plurality of deformable pawls. At least one spherical member is received in the tapering bore and has a diameter greater than a smallest diameter of the tapering bore whereby the spherical member is effectively retained in the tapering bore. A driving member having external threading is threadingly received in the threaded bore for axially engaging the spherical member. By screwing the driving member, the spherical member is forced toward the front end of the sleeve and due to the tapering configuration of the tapering bore, the movement of the spherical member toward the front end of the sleeve forces the pawls to deform outward in a radial direction thereby securing the expansion bolt in a hole defined in for example a wall.

Abstract: The present invention relates generally to a peripheral community apparatus for computers output/input, and more particularly, relates to an apparatus with a firmware that can be upgraded by the current PS2 protocol, wherein the PS2 ports of the peripheral community apparatus for computers output/input are coupled with the PS2 ports of keyboard/mouse on the computer, and the upgraded firmware programs are at first stored in the computer then transmitted into the Flash ROM of the peripheral community apparatus for computers output/input through the existing PS2 ports on both the peripheral community apparatus side and the computer side so that no change of the current connection arrangement is needed.
