Abstract: An aiming device is provided. The aiming device includes an erector tube assembly, a moving plate and a crosshair. The moving plate, disposed on the erector tube assembly, is movable along a direction. The crosshair is disposed on the moving plate. When the moving plate moves, the crosshair moves with the moving plate along the direction.

Abstract: A universal scope mount includes a housing and a pair of mounting assemblies. The housing has a chamber defined through front and rear ends thereof and having an inner contour conforming to an outer contour of a body of a scope or an accessory to be received therein, a channel downwardly exposed and extending parallel to the chamber and a pair of projections formed along respective opposite sides of the channel. The pair of mounting assemblies is used to respectively secure a front end portion and a rear end portion of the housing to the mount base of the firearm. Each mounting assembly includes a slider to be slidably received in the channel of the housing and supported by the projections of the housing, a mount member to be disposed between the housing and the mount base of the firearm, securing means to securely connect the mount member to the upper attachment surface of the mount base of the firearm, and fastening means to reliably assemble the housing, the slider and the mount member together.

Abstract: A lens barrel assembly includes a first lens barrel and a second lens barrel. The first lens barrel includes a peripheral wall having a first end portion, a second end portion opposite to the first end portion, and a plurality of cam slots extending between the first end portion and the second end portion. Each of the cam slots defines two opposite guiding walls. The second lens barrel is disposed slidably in the first lens barrel, and includes an annular body, and a plurality of cam followers mounted on the annular body and extending through the cam slots, respectively. Each of the cam followers has a shank portion, a head portion, and a rolling member disposed around the shank portion and stopped by the head portion. The rolling member has a spherical outer surface for contacting the guiding walls of one of the cam slots.

Abstract: A fabrication of a damascene structure is described. A substrate having a first conductive layer formed thereon is provided. A silicon nitride type of first dielectric layer is formed on the substrate, followed by patterning the first dielectric layer to form a trench like structure. A silicon oxide type of second dielectric layer is then formed on the first dielectric layer and in the trench like structure and an air-gap is concurrently formed in the second dielectric layer that is in the trench like structure. Thereafter, the second dielectric layer is planarized until a surface of the first dielectric layer is exposed. The first dielectric layer is then removed to form a trench, followed by filling the trench with a second conductive layer.
