    摘要: A GaN series surface-emitting laser diode and a method for manufacturing the same are provided. The GaN series surface-emitting laser diode includes: an active layer; p-type and n-type material layers on the opposite sides of the active layer; a first-distributed Bragg reflector (DBR) layer formed on the n-type material layer; an n-type electrode connected to the active layer through the n-type material layer such that voltage is applied to the active layer for lasing; a spacer formed on the p-type material layer with a laser output window in a portion aligned with the first DBR layer, the spacer being thick enough to enable holes to effectively migrate to a center portion of the active layer; a second DBR layer formed on the laser output window; and a p-type electrode connected to the active layer through the p-type material layer such that voltage is applied to the active layer for lasing. The laser output window is shaped such that diffraction of a laser beam caused by the formation of the spacer can be compensated for.

    摘要: An apparatus to generate a character image includes a character image generating unit to generate a character image from a scalable font according to information for generating the character image from the scalable font, a generation frequency list storing unit to store the number of times that the scalable font has been generated as the character image by the character image generating unit, a scalable font converting unit to convert the scalable font into a bitmap font, when the number of times stored in the generation frequency list exceeds a predetermined limit number of times, and a converted font storing unit to store the bitmap font converted by the scalable font converting unit. Accordingly, the scalable font is generated as the character image according to a method of processing a character print command using a bitmap font without mathematical processing to provide a font of a high print quality.

    摘要: A jam removing method and printer using toner a save mode includes detecting a paper jam on a printing route, confirming whether a dot count value of a corresponding image exceeds a preset boundary value, and converting a printing mode into the toner save mode when the dot count value exceeds the boundary value. The paper jam by an image density is prevented from repeating, and successive paper jam is prevented from occurring, user's convenience may be enhanced, and the toner may not be wasted.
