    Abstract: A light deflecting apparatus is employed in a light scanning unit of an image forming device. Such a deflecting apparatus includes a stator having a sleeve disposed at a printed circuit board (PCB), and a core disposed around the sleeve, to which coils are wound; a rotor having a rotor frame connected to an axis which is rotatably supported in the sleeve, and a rotor housing fixed to the rotor frame to surround the core; and a polygon mirror supported on the rotor frame. At least one of the rotor frame and the rotor housing is formed of a plastic material. Because the rotor frame and/or the rotor housing is formed of the plastic material, the high precision manufacture of such a light deflecting apparatus which requires mechanical machining and press working, is not needed. As a result, the manufacture of such a light deflecting apparatus is made simpler and easier; and, likewise, a working time and an exhaustion of manpower are reduced, so that a manufacturing cost is reduced. In addition, an unbalance of weight at the rotor frame and/or the rotor housing, which is influenced by a working precision thereof, is minimized, so that the light deflecting apparatus may maintain a stable performance.

    Abstract: Provided is a load driving device controlling a drive of a load including a driver for periodically turning on/off a current according to a switching clock signal and supplying a average driving current to the load. Further provided is a dimming controller for controlling the driver to turn on/off the drive of the load based on a dimming step. Also provided is a controller for controlling at least one of the driver and the dimming controller so as to make a step interval of the dimming step and a switching clock period of the switching clock signal the same. A load driving device is provided that is capable of stably controlling the dimming of a drive of a load, by improving a linear response characteristic of a driving current according to a dimming control.

    Abstract: Provided is a method of fabricating a CMOS transistor in which, after a polysilicon layer used as a gate is formed on a semiconductor substrate, a photoresist pattern that exposes an n-MOS transistor region is formed on the polysilicon layer. An impurity is implanted in the polysilicon layer of the n-MOS transistor region using the photoresist pattern as a mask, and the photoresist pattern is removed. If the polysilicon layer of the n-MOS transistor region is damaged by the implanting of the impurity, the polysilicon layer of the n-MOS transistor region is annealed, and a p-MOS transistor gate and an n-MOS transistor gate are formed by patterning the polysilicon layer. The semiconductor substrate, the p-MOS transistor gate and the n-MOS transistor gate is cleaned with a hydrofluoric acid (HF) solution, without causing a decrease in height of the n-MOS transistor gate.
