Abstract: Disclosed herein is a spindle motor having a fluid dynamic bearing as an oil gap formed between a rotator and a stator, wherein the stator includes a sleeve having a protruding part extending in a circumferential direction formed on the upper part thereof, the rotator includes a hub including an oil interface forming member positioned under the protruding part of the sleeve and coupled to the lower end thereof, and an oil interface of the oil gap is formed between the upper part of the oil interface forming member and the lower part of the protruding part of the sleeve.

Abstract: A camera interface employing a direct memory access (DMA) unit to digitally perform an image transformation such as “flipping” and “rotating” an image (e.g., to correct for X-axis, Y-axis, or XY-axes mirroring). The image transforming DMA unit includes an address generator and a data selector. The address generator appropriately modifies a frame start address, a burst transfer address, a line start address, of an image frame, based on the X, Y, or XY mirrored image mode. The data selector changes the sequences of words and of pixels in a word based upon the mirrored image mode.

Abstract: Disclosed herein is a cloak-type raincoat which can be rapidly put on so as to prevent garments and personal belongings from becoming wet owing to rain or snow falling suddenly. The raincoat is about 0.05 mm and is very thin, thus allowing a user to walk or perform actions without suffering inconvenience. The raincoat is made of a transparent material, thus easily ensuring visibility, therefore allowing the user to safely walk at night. The volume of the raincoat is small, so that it is convenient to carry or store the raincoat.
