Abstract: Provided is a stator applied to a motor. The stator of the present disclosure may reduce a production cost and simultaneously minimize a motor failure occurring due to corrosion by using an inexpensive steel ball bearing, which is enabled by reducing a magnitude of an shaft voltage that causes the corrosion rather than using a structure (for example, a ceramic bearing or an SGR bearing) for avoiding the corrosion.

Abstract: A camera system disclosed in an embodiment of the invention includes a camera module having an image sensor, a first lens holder having at least one lens, a second lens holder disposed between the image sensor and the first lens holder and having a first lens adjacent to the image sensor, and a driving portion that moves the second lens holder in the optical axis direction; a temperature sensor that detects a ambient temperature of the camera module; a storage portion storing a correction rate of an optical axis distance between the first lens and the image sensor according to the ambient temperature; a temperature compensation portion that drives the driving portion using the ambient temperature and a correction rate of the storage portion to adjust the optical axis distance between the first lens and the image sensor.

Abstract: A home appliance is provided. The home appliance includes a main body having an opening, a door disposed on one side of the main body, the door being configured to open or close the opening, and a damping assembly configured to be operated by the door. The damping assembly includes a first lever installed in the main body, the first lever being configured to be movable when the door is pressed, a second lever connected to the first lever, and a cylinder connected to the second lever, the cylinder being configured to be movable in a direction that is parallel to a movement path of the first lever.

Abstract: Disclosed are a vehicle seat cover made of an artificial suede. The vehicle seat cover includes a top layer provided in the top portion, a bottom layer provided in the bottom portion, and a intermediate layer positioned between the top layer and the bottom layer. Each of the layers has a tricot texture, and the top layer includes the first yarn having a configuration in which the dope dyed microfiber yarn and the first high shrinkage yarn are interlaced. Thus, the suede material may have superior friction fastness and the light fastness and the vehicle seat cover is manufactured at less cost than a vehicle seat cover made of a conventional artificial suede.

Abstract: A method of preparing patterned colloidal crystals includes filling a monomer solution in the interstices between particles of planar colloidal crystals for photopolymerization inside them, and performing a selective photopolymerization process between the colloidal crystals using a mask. In one exemplary method, a first monomer solution for photopolymerization is filled inside planar colloidal crystals. A first selective photopolymerization process is performed inside the colloidal crystals using a mask. A second monomer solution for photopolymerization is filled into the firstly patterned colloidal crystals. At least one additional photopolymerization process is performed inside the firstly patterned colloidal crystals using an additional mask. Through this method, colloidal crystalline regions oriented in the same direction with different refractive indexes can be controlled in a level of ?m. Further, repeated patterns can be inexpensively and easily prepared.
