Abstract: A camera module package is disclosed. The camera module package is capable of preventing defects caused by foreign bodies and enhancing product reliability by reducing the time consumed in a packaging process for manufacturing a camera module, and of reducing the size of a package and manufacturing costs by excluding the use of gold wires.

Abstract: A chrome-free coating composition for surface-treating a hot-dip galvanized steel sheet that includes carbon nanotubes and has excellent electric conductivity, comprising, based on the total solid weight of the composition: (a) 40 to 60 parts by weight of a water-soluble or water-borne organic resin; (b) 20 to 40 parts by weight of an inorganic metallic sol; (c) 2 to 5 parts by weight of a carbon nanotube paste including carbon nanotube (CNT); (d) 2 to 5 parts by weight of a metal oxide/phosphate-based anti-corrosion agent; (e) 5 to 15 parts by weight of an organic metal complex; (f) 3 to 7 parts by weight of a carbodimide cross-linking agent; and (g) the balance of water, ethanol or a mixture thereof. The steel sheet surface-treated with the composition may be useful to secure corrosion resistance without including a chrome component and shows its electric conductivity even when the coating composition is used at a coating amount of 1000 mg/m2 or more.

Abstract: Provided is a composition for forming a photocatalytic coating layer, a process for preparing said composition, a self-cleaning article comprising a photocatalytic coating layer comprising said composition and a process for preparing said self-cleaning article. The composition may be used to prepare a self-cleaning article having excellent anticorrosion and processability by one coating and drying procedure, without several coating and drying procedures.

Abstract: Disclosed herein is a device and method for automatically controlling continuous auto focus. The device includes a lens unit installed in a camera module, and configured to receive images of an external subject; a lens actuation unit for moving the lens unit along an optical axis so as to focus on a subject; an image sensor for receiving the external images, converting the external images into image signals, and outputting the image signals; a computation unit for detecting focus values and feature parameters; a mode determination unit for automatically performing switching between general mode, specific mode and tracking mode, setting the mode, and automatically setting a fixed or variable window according to the set mode using the detected feature parameters; and a lens control unit for generating a control signal for controlling the lens actuation unit so as to perform continuous auto focus according to the detected focus values.

Abstract: The present invention relates generally to a system for measuring dispersion degree of a ferrite core of components of a deflection yoke, and more particularly to a permeability detection system of a ferrite core using a magnetic field induction method which extracts inferior ferrite cores by measuring a characteristic of the ferrite core through a winding wire and by detecting the dispersion degree of the ferrite core, during its production operation.
