A focusing and adjusting method to be implemented using a pair of binoculars having a pair of optical units, an image-capturing unit, and a beam-splitting unit. Each optical unit includes an objective lens unit, an ocular lens assembly distanced from the objective lens unit along a first direction, and a prism assembly disposed therebetween. The beam-splitting unit is disposed between the prism assembly of one optical unit and the image-capturing unit. The method includes: adjusting a distance along a second direction perpendicular to the first direction between the optical units; simultaneously adjusting distances along the first direction between the objective lens units and the prism assemblies of the optical units; and independently adjusting distances along the first direction between the prism assemblies and the ocular lens assemblies of the optical units.

A 360-degree sprinkler head is comprised of a main member, an adjustment ring, a cap and a lock bolt. The main member is a hollow cylinder consisting of an annular member positioned at the center with a plurality of coupling tabs integrated to the hollow cylinder and a stepped edge disposed at the upper end of the hollow cylinder. The adjustment ring has a plurality of coupling tines along its lower side conjoined to a round nut constituting a stepped annular member, a helical rib proceeding around the surface opening at the upper end of the annular member, and a beveled surface articulated as an outlet along the inner edge of the helical rib. The cap is a funnel-shaped cover member consisting of a threaded section and a spigot tube sequentially formed at the middle lower section, a passage through the center of the entire cover member, and a plurality of slots disposed at intervals in the outer wall of the spigot tube, with a lip formed along the outer periphery of the spigot tube.

A hydrophilic-hydrophobic transformable composite film is disclosed, which has an iron-containing substrate; a silicon-containing layer formed on the iron-containing substrate; and a titanium oxide layer formed on the silicon-containing layer. The hydrophilic-hydrophobic transformable composite film uses UV-light to switch its hydrophilic and hydrophobic property. Also, a method of fabricating the above composite film is disclosed. According to the present invention, an anatase oxide layer can be obtained from the sol-gel techniques, in which the particle size of the titanium dioxide is controlled and a modified surface coating with evident photo-catalyticity is achieved.

An electric dust-proof device includes a driving mechanism disposed on a base seat unit, and a dust-proof plate driven by the drive mechanism. The driving mechanism includes a power unit, a drive unit driven by the power unit, a driving seat driven by the drive unit, and a driven seat driven by the driving seat. The dust-proof plate is driven by the driven seat to move between an open position and a close position.

Disclosed is a hand-held input device having a rotating mechanism. The hand-held input device includes a shell body and a rotating component. An outer surface of the shell body forms a storage cavity in which a spindle hole and a guide groove are formed. The rotating component is assembled with a spindle and a guider that the spindle and the guider match with the spindle hole and the guide groove of the shell body respectively. The spindle is fixed a pressing ring with an elastic part therebetween. A cover is capped on the storage. The elastic part keeps a space between the shell body and the rotating component. A rotation limitation mechanism limits the rotation of the rotating component within a specified rotating angle range with respect to the shell body by the limitation of the guide groove to the guider.
