Abstract: A brightness enhancement film includes a substrate, a plurality of curved prism units and a light-diffusing microstructure layer. The curved prism units are extended in parallel and formed on a first surface of the substrate. Each of the curved prism units includes at least one meandering surface to provide with changes in curvature. Thus, the meandering surface of the curved prism unit is able to refract incident light in two dimensions with respect to the substrate that may enhance entire light-collecting efficiency in two dimensions. The light-diffusing microstructure layer is formed on a second surface of the substrate.

Abstract: The invention is to provide a vibratory double-axially sensing micro-gyroscope, which includes a base, on center of which a supporting hub is arranged, and plural suspending arms are extended outwardly with equal altitude and in radial direction from the supporting hub and, at the outside end of the suspending arm, a platform is formed, and a capacitance sensing electrode or a static-electricity driving electrode is plated respectively at each side of the platform top, below which a static-electricity driving electrode or a capacitance sensing electrode is arranged; take a preferred embodiment of the present invention for example, if the capacitance sensing electrode is arranged at top of the platform and the static-electricity driving electrode is arranged below the platform, then the suspending arm and the platform will vibrate vertically by the attraction of the static-electricity when applying driving voltage, and the vibratory phase difference between two adjacent suspending arms and the platform is 180 degrees; when the gyroscope is rotated horizontally, the suspending arm and the platform will generate horizontal displacement caused by Coriolis force and, by measuring the change of capacitance value, the magnitude of the angular velocity of vibration is obtained; since its structure has symmetrical property, so it has sensing ability in both X or Y axes and, because it has superior stability and is able to resist environment noise and vibration, its sensing capability is enhanced and, since its machining method is simple, so it is adapted for mass production for having lower manufacturing cost.

Abstract: A wash-free air-guiding cover includes a cover having a body with a fixing seat disposed on a side thereof. A ventilation tube is disposed on the fixing seat and includes a ventilation hole intercommunicated with the other side of the body. An air guiding device is mounted to the fixing seat and includes a tube having first, second, and third air guiding spaces. The air guiding device further includes first and second sealing members and first and second flow guiding rods. Air flowing into the tube must flow zigzag through the first, second, and third air guiding spaces and between the first and second flow guiding rods and the second and third air guiding spaces, assuring smooth flow of air during the painting operation and avoiding the paint from leaking via the ventilation tube and the ventilation hole of the cover.
