Abstract: A fusing unit and an image forming apparatus to form an image on a recording medium including a fusing unit are provided. The image forming apparatus includes a heating member having a surface divided into a plurality of heating regions and heating the recording medium, and a pressurizing member to apply pressure to the recording medium, the fusing unit fusing the image to the recording medium by applying heat and pressure to the recording medium, a driving unit to supply rotational force to the pressurizing member, and a power supply to supply power to the heating member and the driving unit, wherein the heating regions have different heating values per unit area. The image forming apparatus prevents overheating of a paper-contact heating region without idling the fusing unit in order to radiate heat accumulated in the paper-contact heating region.

Abstract: A semiconductor device and a power-off method of the semiconductor device, the semiconductor device including a first power source group including first and second power sources, a second power source group including a third power source and a power sequence controller. The power sequence controller performs power-on operations and power-off operations of the first to third power sources. The power sequence controller starts a power-off operation of the first power source group at a first time, and starts a power-off operation of the second power source group when the power voltage of the first power source group becomes a first voltage or when a first reference time has passed from the first time.

Abstract: Disclosed is a refrigerator including an ultrathin wall type insulating wall having a reduced thickness while maintaining insulating performance, so as to increase the capacity of a storage chamber. A vacuum insulating material is disposed inside the insulating wall so as to ensure the insulating performance of the insulating wall, and a foam material, in the portion in which the vacuum insulating material is not disposed, is disposed to be thicker than a foam material in the portion in which the vacuum insulating wall is disposed, such that the insulating wall, which maintains insulating performance while maintaining the insulating wall having an overall ultrathin shape, can be formed. Furthermore, auxiliary vacuum insulating materials are additionally disposed in the insulating wall corner regions in which the vacuum insulating material is not disposed, such that the ultrathin wall-type insulating wall is formed while maintaining the overall insulating performance of the refrigerator, thereby reducing the total thickness of the insulating wall so as to increase the capacity of the storage chamber, and enabling a slim design of the refrigerator such that the aesthetics of the refrigerator can be improved.
