A data I/O apparatus for use in a memory device. The data I/O apparatus for use in the memory device performs data transmission using the same polarity when neighbor global I/O lines have opposite polarities to reduce coupling noise generated between global I/O lines acting as data I/O lines of a memory device, performs data recovery, and basically deletes the coupling noise, such that it reduces the failure rate of the memory device.

A method for eliminating blooming streak of an acquired image is capable of eliminating blooming streaks in the acquired image photographing an object together with a light source by mutually replacing the blooming streaks in the acquired image with a partial image corresponding to the blooming streaks from other acquired image, wherein each image is acquired by cameras with changing the arrangement direction of the CCD sensors of the cameras.
摘要:
A variable capacity rotary compressor to prevent an eccentric bush and a locking pin from being deformed or worn out due to a variance in a pressure of a compression chamber as a rotating shaft rotates. The compressor includes upper and lower compression chambers having different interior capacities thereof, and a rotating shaft. Upper and lower eccentric cams are provided on the rotating shaft to be eccentric from the rotating shaft in a common direction. Upper and lower eccentric bushes are fitted over the upper and lower eccentric cams, respectively, with a slot provided at a position between the upper and lower eccentric bushes. The locking pin operates to change a position of the upper or lower eccentric bush to a maximum eccentric position. Further, surfaces of parts around first and second ends of the slot are heat-treated, thus increasing a hardness thereof.
摘要:
A variable capacity rotary compressor, which is designed to make an internal pressure of a compression chamber, where an idle rotation is executed, be equal to an outlet side pressure of the rotary compressor, thus minimizing a rotating resistance. The compressor includes a housing partitioned into two compression chambers having different capacities by a partition plate. A rotating shaft rotates in the compression chambers. Two eccentric units are mounted to the rotating shaft to be placed in the compression chambers, and execute a compression rotation and an idle rotation according to a rotating direction of the rotating shaft. A pressure control unit functions to apply the pressure of the outlet side of the compressor to the compression chamber which executes the idle rotation. The pressure control unit includes a path control channel which is vertically provided through the partition plate to be placed at a position outside the compression chambers. Two valve seats are seated in opposite ends of the path control channel. A valve member is movably set in the path control channel. A communicating path is provided through the partition plate to make the outlet side communicate with the path control channel. Two inlet channels are provided at predetermined positions of the housing to make the path control channel communicate with the compression chambers.

According to an embodiment, the method comprises receiving first graphic information that comprises animation data from a first source, the first graphic information being associated with audio/video (A/V) data and comprising a MNG (Multimedia Network Graphics) file; extracting second graphic information from the first graphic information, the second graphic information comprising PNG (Portable Network Graphics) file; decoding the second graphic information into first image data; and reproducing the first image data in the form of animated image, based on a control data.
摘要:
Disclosed herein is a system for providing lyrics for a plurality of digital audio files. The system includes at least one terminal, a server, and a database server. The terminal selects a digital audio file among the digital audio files, and transmits tag information to receive lyrical data assigned to the selected digital audio file. The server retrieves the lyrical data, which is assigned to the selected digital audio file, using the tag information on the digital audio file transmitted from the terminal, and transmits the lyrical data to the terminal. The database server transmits the lyrical data in response to a request from the server and previously stores lyrical data in which lyrics are synchronized with digital audio files.
