Abstract: A method and apparatus to store information on an amount of toner used. The method includes determining whether a customer replaceable unit monitor (CRUM) memory to store information on an amount of used toner is included in a cartridge of an image forming device; storing the information on the amount of used toner in a non-volatile memory of the image forming device when the CRUM memory is not included in the cartridge of the image forming device; and storing the information on the amount of used toner in the CRUM memory when the CRUM memory is included in the cartridge.

Abstract: A thin film pattern forming device includes a chamber having an inner space communicated with the outside, a first fixing unit provided in the chamber case, a pattern electrode plate having a protrusion electrode protruded with a certain shape, and fixed to the first fixing unit, a second fixing unit provided in the chamber case and spaced apart with a certain gap from the pattern electrode plate, for fixing a substrate on which an inked metallic nano-material is deposited, a power supply unit for supplying power to the first fixing unit and the second fixing unit so as to form electrodes thereat, and a drying unit for drying the inked metallic nano-material patterned on the substrate. A metal thin film line such as a gate line can be simply formed on the substrate, and a processing time can be shortened. Furthermore, required equipment is simplified thus to reduce an installation cost and to enhance a productivity.

Abstract: An electro-photographic image forming device that is capable of controlling a print speed and a method for controlling the same, wherein the electro-photographic image forming device has an engine mechanism including a laser scanning unit, a developing unit, a transfer roller, and a fixing unit. The electro-photographic image forming device further includes a first driving unit for driving the laser scanning unit, a second driving unit for driving the photosensitive medium, the developing unit, the transfer roller, and the fixing unit, and a controller for controlling the first and second driving units so as to have the laser scanning unit driven at a first driving speed and to have the photosensitive medium, the developing unit, the transfer roller, and the fixing unit, driven at a second driving speed in the engine mechanism when it is determined that a print mode for printing desired print data is set to a draft mode.

Abstract: A method for laminating a circuit pattern tape over a wafer, involving the steps of preparing a circuit pattern tape formed with an adhesive layer, along with a wafer, detecting at least one reference position of the prepared circuit pattern tape and at least one reference position of the prepared wafer using visual detecting means, outputting results obtained at the detecting step in the form of visual images capable of allowing a comparison of the detection results, carrying out a reference position correction involving movements of the wafer in an X-axis and/or a Y-axis direction and/or by a desired angle, thereby allowing the reference position of the circuit pattern tape and the reference position of the wafer to correspond to each other, and laminating the circuit pattern tape over the wafer when the reference positions correspond to each other.

Abstract: An apparatus and method for automatically converting an operating mode such as a telephone mode, a facsimile mode, a telephone/facsimile mode, and a telephone answer mode of a facsimile system.
