Abstract:
A fusing device to fuse an image to a printing medium, the fusing device including: a heating roller; a first pressing roller, which presses the printing medium against the heating roller; and a second pressing roller which attached to the first pressing roller, to detach the printing medium from the first pressing roller. The first and second pressing rollers are biased against the heating roller such that the first and second pressing rollers move according to a change in a position of the heating roller.

Abstract:
An image forming apparatus and a fixing unit thereof are disclosed. The fixing unit includes a heating roller, a press roller mounted in close contact with the heating roller to apply heat and pressure to the printable medium with the heating roller, a press lever to press the press roller toward the heating roller, a press spring connected to the press lever, a release device to operate the press lever to release pressing force exerted on the press roller, and a power conversion device to transmit driving power generated from a main driving source to drive the heating roller to the release device. Accordingly, since the press lever pressing the press roller to closely contact the heating roller can be operated by the driving power of the main driving source, the jammed printable medium can be easily removed.
Abstract:
Methods and related liquid crystal display devices are disclosed that reduce/avoid a tearing effect in displayed images. A scan time of a scan clock signal of a display is detected. A write time of a write clock signal that writes data into a memory for display on the display is detected. The write time is regulated in response to a comparison of the scan time of the scan clock signal to the write time of the write clock signal.
Abstract:
A method and apparatus for transmitting data to an Access Point (AP) and a Mobile Station (MS) in a Time Division Duplex (TDD) optical repeater. A main donor generates a control frame for controlling a remote, upon receipt of data from the AP, and transmits the control frame to the remote during a non-downlink transmission period. The remote analyzes the control frame received from the main donor, detects sync information about a downlink signal and an uplink signal, and remote control information from the analyzed control frame, performs a control operation according to the detected remote control information, and generates a status frame for notifying the main donor of the status of the remote upon receipt of data from the MS. The status frame is transmitted from the remote to the main donor during a non-uplink transmission period.
