    摘要： The present invention relates to a power factor correction circuit that can reduce distortion of input current in a switching mode power supply. The power factor correction circuit provided in the present invention basically comprises a first inductor which is electrically connected at a first end thereof to an input terminal, a second coil that is coupled to the first inductor to form an induced voltage, a switch electrically connected to the a second terminal of the first inductor, and a switching control unit for controlling turn-on and turn-off of the switch. In such a power factor correction circuit of the present invention, the switching control unit is configured to differently set a turn-on period of the switch depending on the input voltage by generating a signal for controlling the turn-off of the switch using a second coil voltage induced at the secondary coil of the inductor by input voltage or a directly sensed input voltage. Accordingly, distortion of input current can be effectively corrected.

    摘要： An apparatus for easing an impact on a boom of an excavator and a method of controlling the same are disclosed, which can minimize the vibration occurring in the boom due to the impact on a boom cylinder by actively controlling an amount of hydraulic fluid being supplied to the boom cylinder when the operation of the boom cylinder is suddenly stopped due to an operator's sudden manipulation of an operation lever for a working device. The apparatus includes first and second hydraulic pumps; a boom cylinder; a main control valve; an operation lever for supplying pilot signal pressure to a spool of the main control valve when an operator manipulates the operation lever; operation lever detection means for detecting boom up and boom down signal pressures according to an amount of manipulation of the operation lever; boom cylinder pressure detection means for detecting pressures generated in a large chamber and a small chamber of the boom cylinder; a controller for calculating and outputting a control signal of the main control valve if the boom cylinder has been suddenly stopped; and boom vibration preventing means for controlling the pilot signal pressure being supplied from the second hydraulic pump to the main control valve.

    摘要： The invention provides a vertical group III-nitride light emitting device improved in external extraction efficiency and a method for manufacturing the same. The method includes forming an undoped GaN layer and an insulating layer on a basic substrate. Then, the insulating layer is selectively etched to form an insulating pattern, and an n-doped AlxGayIn(1-x-y)N layer, an active layer and a p-doped AlmGanIn(1-m-n)N layer are sequentially formed on the insulating pattern. A conductive substrate is formed on the p-doped AlmGanIn(1-m-n)N layer. The basic substrate, the undoped gaN layer and the insulating pattern are removed, and an n-electrode is formed on a part of the exposed surface of the n-doped AlxGayIn(1-x-y)N layer.
