    摘要： Provided is an unpowered and automatically flushing toilet seat, for a water tank, having detachable and waterproof functions. A loading lever rotates, for the descending movement of a toilet seat, and presses a loading member, thereby enabling enhancement of the transmission efficiency of the force and smooth operation. Since the loading member maintains the loaded state until a toilet paper time and flush control unit presses and releases the loading member, which has been moved and loaded by the pressing of the loading lever, a user can easily acquire time for discarding toilet paper.

    摘要： Disclosed is a method of sequencing character information in order to increase precision of character recognition. The method includes: a pre-processing that extracts character information from an image to binarize the extracted character information through a predetermined threshold and extracts and thins a center line of the binarized character information; normalizing the pre-processed character information to character information according to a predetermined criteria; and sequencing the normalized character information using structural features including an end point or a divergence point of the character information. The present invention suggests an angle normalization method of input character information, a structural feature position determining method, and a structural feature numeral string generating method to strongly recognize characters configured by various fonts obtained from a natural scene regardless of an angle or a size of the characters.

    摘要： Disclosed is a display apparatus including a first case and a second case coupled to each other to define an external appearance of the display apparatus. A fastening guide extends from an inner surface of the first case, and a fastening member is engaged with the fastening guide. The fastening member is provided with a boss portion for screw-fastening. The first case and second case are coupled to each other using the fastening guide and fastening member having a thin thickness, whereby a reduced thickness of fastening parts and stable inter-coupling of the first case and second case are accomplished.

    摘要： A delay locked loop (DLL) circuit has a first delay line that delays a received external clock signal for a fine delay time and then outputs a first internal clock signal; a duty cycle correction unit that corrects a duty cycle of the first internal clock signal and then outputs a second clock signal; a second delay line that delays the second clock signal for a coarse delay time and then outputs a second internal clock signal; and a phase detection and control unit that detects the difference between the phases of the external clock signal and the fed back second internal clock signal, and controls the fine delay time and the coarse delay time. The DLL circuit performs coarse locking and fine locking by using different type delay cells, and thus consumes a small amount of power and robustly withstands jitter and variation in PVT variables.
