Abstract: The present invention relates to: a steel material for hot forming, used for a vehicle and the like; a hot-formed member; and a method for manufacturing same. In the method, when the formed steel material is skin pass rolled, rolling pressure and roughness of skin pass rolling rolls are controlled so that bendability can be improved.

Abstract: The present disclosure provides a hot-press formed part comprising a plated steel sheet and an aluminum alloy plated layer formed on the plated steel sheet, wherein the aluminum alloy plated layer comprises: an alloying layer (I) formed on the plated steel sheet and containing, by weight %, 5-30% of Al; an alloying layer (II) formed on the alloying layer (I) and containing, by weight %, 30 to 60% of Al; an alloying layer (III) formed on the alloying layer (II) and containing, by weight %, 20-50% of Al and 5-20% of Si; and an alloying layer (IV) formed continuously or discontinuously on at least a part of the surface of the alloying layer (III), and containing 30-60% of Al, wherein the rate of the alloying layer (III) exposed on the outermost surface of the aluminum alloy plated layer is 10% or more.

Abstract: A sterilization device includes a housing; a sterilization unit which emits germicidal light for sterilization of at least one target area to be sterilized; and a drive unit which moves at least a part of the sterilization unit between the outside and inside of the housing through an opening provided in the housing.

Abstract: A sterilization apparatus includes a housing; a sterilization unit for irradiating, with sterilization light, at least one region to be sterilized; and a driving unit for moving the sterilization unit into and out of the housing via an opening of the housing and rotating the sterilization unit about a rotation axis.

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: An apparatus of detecting a position of a rotating member includes a cam plate connected to the rotating member. The cam plate includes a plurality of segments that are spaced apart from each other. The plurality of segments are disposed in an annular shape. A fixed ring is disposed between the cam plate and the worm wheel. A first contact point is in contact with an interior portion of any one of the segments and maintaining a fixed state. A second contact point is formed at an external circumferential portion of any one of the segments and is in contact with the fixed ring.
