Abstract: The present invention provides an aluminum-iron-plated steel sheet, having excellent mold wear resistance, for hot press forming, and a manufacturing method thereof.

Abstract: The present invention relates to a composition and health functional food for preventing and treating a respiratory inflammation disease using a mixed herbal mixture. Through various experiments, for example, determination of the cell number of BAL (bronchoalveolar lavage) (Experimental Example 1); Determination of CD11b+/Gr-1+ ratio in leukocyte within BAL fluid (Experimental Example 2); Determination of expressed RNA level of inflammatory cytokines in lung tissue (Experimental Example 3); Determination of expressed RNA level of inflammatory cytokines in BALF (Experimental Example 4); Lung histology (Experimental Example 5); Brief Clinical test (Experimental Example 7) etc, it has been verified that the inventive combined extract showed more potent inhibiting effect on respiratory inflammation disease than each herb extract.

Abstract: The present invention relates to a mirror device for a sun visor of a vehicle, in which when a cover of a mirror mounted to a sun visor is opened or closed, the mirror can be operated smoothly and completely, comprising: a mirror housing having a mirror and a cover sliding from the mirror housing to open or close the mirror, wherein the mirror housing and the cover are coupled to each other by an elongation member. Accordingly, the cover moves smoothly in a semi-automatic sliding manner by means of an elastic body, thereby restraining noise from being generated.

Abstract: An air ventilator for ventilating cold or heated air into the interior of an automobile from a duct is provided. The air ventilator includes a pair of wing units having a plurality of wings fixed in various angles, a housing for receiving the wing units, and a gear mounted between the wing units and engaged to be driven by a motor to rotate the wing units simultaneously to automatically change the direction of ventilated air. The pair of wing units preferably have their wings twisted to direct air flow in opposite directions.

Abstract: A metal thin film with an ohmic contact for light emit diodes and a method of producing such a film are disclosed. The metal thin film has a p-type gallium nitride (GaN) semiconductor layer. Nickel (Ni), platinum (Pt) and gold (Au) layers are deposited on the GaN semiconductor layer in a way such that the gold layer forms a top layer, with either one of the platinum and nickel layers being selectively used as an inter-diffusion barrier between metal layers. The inter-diffusion barrier may be formed by depositing platinum between the nickel and gold layers, thus forming an Ni/Pt/Au metal thin film, or formed by depositing nickel between the platinum and gold layers, thus forming an Pt/Ni/Au metal thin film. In the method, a GaN semiconductor is washed so as to be free from carbide and oxide layers. The Ni, Pt and Au layers are formed on the GaN semiconductor layer through a vacuum deposition process at 5×10−5-2×10−1 torr.
