    摘要： Disclosed are a hinge assembly and a mobile device having the hinge assembly. In the mobile device, a rotation portion 14 slides and rotates on a base portion 10, so as to be inclined to the base portion 10. For this reason, the rotation portion 14 is connected to the base portion by means of the hinge assembly 20 so as to slide and rotate on the base portion 10. The rotation portion 14 slides on the base portion by a predetermined distance, and then rotates to be inclined at a desired angle with respect to the base portion 10. The rotation portion 14 easily rotates with respect to the base portion of the mobile device, so that the status of the mobile device can be easily converted. Further, when the status of the mobile device is converted, the front, rear, left and right of a display screen is not changed. As a result, the mobile device should not have a structure of changing a display direction of the display screen. Further, there is an advantage in that an electric connection between the base portion and the rotation portion by means of a connection link mechanism can be stably achieved.

    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.

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.
