    摘要： The plasma display apparatus includes a first electrode and a second electrode which include a transparent electrode and a bus electrode, and a black layer formed on the front substrate includes a first black layer formed on the position overlapped with the barrier rib, and a second black layer formed between the transparent electrode and the bus electrode. A contrast is improved by a separate type BM structure where the first black layer is separated from the second black layer, and the reactive current is reduced by lowering the panel capacitance. The light emission by a discharge is smoothly performed by controlling the width of the upper portion and the lower portion of the second barrier rib, and the width of the first barrier rib according to the width of the second barrier rib.

    摘要： A Brushless Direct Current (BLDC) motor starting method and device are provided, in which startup noise and vibration and startup failure rate can be reduced using a constant low-speed startup scheme when the BLDC motor is in sensorless startup mode, and PWM duty is also maintained at low level when the BLDC motor starts up, thereby preventing an excessive current from occurring due to desynchronization of the motor at startup, so that it is possible to optimize specifications of an inverter in the BLDC motor. The BLDC motor starts up with a startup speed and a PWM duty of a rotor of the BLDC motor being kept constant, and the BLDC motor switches to sensorless mode if a position of the rotor is detected a predetermined number of times or more during a specific time.

    摘要： Provided is a frequency converter that can remove a DC offset and suppress spurious response and intermodulation. The frequency converter receives a reference signal and a local oscillator signal and outputs a frequency component corresponding to the sum or difference of the reference signal and the even-order harmonics of local oscillator signal. The frequency converter includes a reference signal input part including a pair of MOS transistors connected in a differential amplifier form, which have gates to which positive and negative reference signals having a differential phase difference therebetween are respectively input, and first, second, third and fourth frequency conversion parts each of which is connected to the reference signal input part and includes a pair of MOS transistors. Local oscillator signals having a differential phase difference therebetween are input to the gates of the MOS transistors of the first and second frequency conversion parts. Local oscillator signals, which have phases orthogonal to phases of the local oscillator signals input to the first and second frequency conversion parts, are input to the gates of the MOS transistors of the third and fourth frequency conversion parts.

    摘要： A brushless DC motor prevents disconnection of a magnetic flux and to minimize leakage of the magnetic flux, thereby reducing torque ripple. A plurality of magnetic flux-disconnection preventing holes are arranged in an outer periphery of a rotor core between installing holes into which magnets are fitted. The plurality of magnetic flux-disconnection preventing holes are symmetrical at both sides about a first line connecting a center of the rotor core to a center between the adjacent installing holes, and an angle between the first line and a second line connecting the center of the rotor core to an outermost end of the plurality of magnetic flux-disconnection preventing holes is about 15˜20°. A length between an outer periphery of the rotor core and an outer periphery of the plurality of magnetic flux-disconnection preventing holes is smaller than a gap between the rotor core and the stator.
