Abstract: Provided is a nitride semiconductor light emitting device having enhanced output power and resistance to electrostatic discharge. The light emitting device comprises an n-side contact layer formed on a substrate, a current diffusion layer formed on the n-side contact layer, an active layer formed on the current diffusion layer, and a p-type clad layer formed on the active layer. The current diffusion layer is formed by alternately stacking at least one first InAlGaN layer having a higher electron concentration than that of the n-side contact layer and at least one second InAlGaN layer having a lower electron concentration than that of the n-side contact layer.

Abstract: The disclosed technology relates to changing and pushing a sound source of a supplementary service using a ring back tone on calling. The first embodiment relates to a method and apparatus for changing a sound source of supplementary service using a ring back tone on calling. The second embodiment relates to a method and apparatus for pushing a sound source of a supplement service of a calling party to that of a called party on calling.

Abstract: Disclosed is an image-forming apparatus having a pause function and a method therefor. The image-forming apparatus having a pause function has an image-scanning unit for moving a loaded document along a transfer path and scanning the loaded document; a pause button for inputting a pause signal requesting to pause the scanning; a control unit for determining whether the pause signal has been input, controlling the image-scanning unit to pause the scanning operations if the pause signal is inputted, and processing a portion of the image scanned until the pause of the scanning operations; and a storage unit for storing the scanned portion of the image.

Abstract: An apparatus for and a method of converting an address in a semiconductor memory device sequentially performing a data write operation on addresses from an upper address, by performing a write or read operation after converting inputted logical addresses into physical addresses in a memory device by using an address converting table. As a result, an operation speed of the system is improved and power consumption is reduced.

Abstract: A method and apparatus for printing provides for direct printing out of image files received from a system that is external to the printer. The method includes the step of determining whether or not a command mode of the printer at present is a Direct Image File Printing System mode, if data are inputted to the printer from a host computer that is external to the printer. The method may also include the step of converting the inputted data into an image form which can be outputted so as to print them out depending on the image file type mode. This step may occur if the command mode of the printer at present is found to be the Direct Image File Printing mode upon a result of the examination.
