The water-cooled heat dissipation module assembly includes a housing unit provided in the form of a housing having an opening portion at least partially opened at one side thereof. The housing unit and at least a part of a rim region of the cooling unit are made of a plastic material, and the housing unit and the cooling unit are joined to each other by plastic welding using a laser.

Abstract: A motor includes a rotor and a stator, in which the rotor includes: a rotor core including a plurality of core portions disposed on a rotation shaft along an axial direction of the rotor, wherein the rotor core includes a core flow path through which a cooling fluid passes through each core portion; and a cooling plate which is inserted between the two divided core portions so that both surfaces are joined to the two neighboring core portions, and a distribution flow path that distributes the cooling fluid supplied from a cooling flow path of the rotation shaft into the core flow path of the two neighboring core portions is provided between at least one of the two neighboring core portions and the cooling plate.

Abstract: The present invention relates to a method of preparing a positive electrode active material for a lithium secondary battery, and more particularly, to a method of preparing a positive electrode active material for a lithium secondary battery, which is able to improve electrochemical properties and stability by controlling the specific surface area of a positive electrode active material.

Abstract: The present invention relates to a positive electrode active material and a lithium secondary battery using a positive electrode comprising the same, and more particularly, to a positive electrode active material which has improved electrochemical properties and improved stability by controlling a pore area and a pore shape of a lithium composite oxide included in the positive electrode active material by adjusting the proportions of ammonia and caustic soda, used in co-precipitation for synthesizing a precursor of the positive electrode active material, and a lithium secondary battery using a positive electrode containing the positive electrode active material.

Abstract: A body for a vehicle includes a base part extending in a longitudinal direction of the vehicle and including a flange portion being open outward of the vehicle, a tubular part accommodated on and coupled to the flange portion of the base part and shaped in a pipe with a closed section, and an external garnish coupled to the base part or the tubular part to cover an external portion of the tubular part.

Abstract: An embodiment vehicle body includes a tubular part extended in a longitudinal direction of a vehicle and having a hollow shape, a base part in which the tubular part is inserted, the base part integrally connecting an A pillar to a side portion of a roof, and an outer garnish shaped to be extended in the longitudinal direction along the base part and coupled to the base part to cover the base part.

Abstract: The present disclosure relates to a virtual reality control device. The virtual reality control device comprises a pedestal, an upper body supporting element connected to an upper part of the pedestal, a lower body supporting element connected to a lower part of the pedestal, a central shaft whose one end is connected to the pedestal and another end is connected to a central portion of the upper body supporting element, and one or more encoders whose ends are connected to the pedestal and the other ends are connected to the upper body supporting element. The upper body supporting element makes a movement around the central shaft on the basis of a movement of the user, and the one or more encoders detect at least one of a linear displacement, a rotation angular displacement, and a speed depending on the movement of the upper body supporting element to generate first signals.

Abstract: A camera module includes a lens barrel having at least one lens disposed in an optical axis direction, a housing having the lens barrel disposed therein, and a case coupled to the housing to cover the outer surfaces of the housing. The case may include at least one of a protrusion part protruding inwardly from an upper edge of the case, a coupling forming part protruding outwardly from the upper edge of the case, and a coupling part protruding from an outer surface of the case. The protrusion part, the coupling forming part or the coupling part may be formed integrally as one piece with the case.

Abstract: This invention relates to a coating layer structure of a basic material of a mold, which exhibits good adhesion between a coating material and a basic material and does not cause cracking when coated. Such a coating layer structure includes an ion nitriding layer formed at the surface of the basic material, a middle coating layer formed on the ion nitriding layer using AlTiCrN, AlCrSiN, AlTiSiN, or AlTiCrSiN, and a surface coating layer formed on the middle coating layer using AlTiCrCN, AlCrSiCN, AlTiSiCN, or AlTiCrSiCN.

Abstract: A camera module package. A housing is provided with a lens barrel having at least one lens contained therein. At least one IR filter is also provided in the housing. A board, which is assembled to the housing, has at least one reinforcement material stacked thereon and at least one passive device mounted thereon. An image sensor is assembled to a lower surface of the board with its image region exposed through a window of the board. The present invention prevents contamination by an adhesive spreading over outer periphery of the board during flip-chip bonding of the board and the sensor, increases the rigidity of the board to prevent damage to the board during the assembly into the housing, and promotes miniaturization of the module.

Abstract: The present invention provides a slot-in type optical disk player which has a guide unit to guide an optical disk, inserted into an inlet, to a central portion of the inlet of the optical disk player, and a disk guide device to allow the optical disk player to play either of 80 mm and 120 mm optical disks. The disk guide device includes a chucking plate, a guide arm, a select arm, a push arm and a push lever. As such, the optical disk player of the present invention plays either of the 80 mm and 120 mm optical disks, so that the optical disk player is economical and practical. Furthermore, the optical disk player has the guide unit which is provided in a disk loading part.
