Abstract: The present invention relates to a compressor and, more specifically, to an air compressor for a vehicle, which can support a rotor disk and form a cooling flow channel by a first cover and a second cover, and thus can improve cooling efficiency while increasing manufacturability.

Abstract: The present invention relates to an air foil journal bearing in which air is introduced between a foil and a rotor rotating at high speed and generates pressure to support a radial load of the rotor and allow the rotor to rotate smoothly, and more particularly, to a housing fixing structure of an air foil journal bearing that improves durability against external impact or vibration by restricting an axial movement of a bump by means of two opposite ends of the bump and a top foil fixing portion.

Abstract: A multipurpose dryer according to an embodiment of the present disclosure allows free use of both hands during drying by adjusting the direction of a nozzle. The multipurpose dryer includes a body part including a blower inside to suck outdoor air, heat or cool it and force the heated or cooled air, and a manipulation panel outside to control the blower, a hose part including a first hose capable of freely bending and maintaining a deformed shape with one end coupled to the body part and the other end formed as a free end, and a second hose capable of freely bending and positioned inside the first hose, with one end coupled to the blower and the other end formed as a free end, and a nozzle part coupled to the other end of the second hose to spray the hot or cold air supplied from the blower.

Abstract: A high-airflow blower fan including an impeller having a mounting hole in which a driving motor is mounted, and a pair of blades repeatedly disposed on an upper surface and a lower surface of the impeller at a first interval along a radial direction, wherein the pair of blades includes a first blade configured to extend with a curvature in an inner direction from an outer circumference of the impeller, and a second blade disposed to be spaced apart from the first blade at a second interval in a clockwise direction or in a counterclockwise direction and configured to extend relatively smaller than a radial length of the first blade in an inner radial direction from the outer surface of the impeller.
