Abstract: Disclosed herein is an apparatus and method for detecting a fault in a digitizer. The apparatus includes a function generator for generating test signals, a transmitting switch for transmitting the test signals generated by the function generator to a selective part or all of X- and Y-channels of a transmitting digitizer, a receiving digitizer arranged in a shape identical to that of the transmitting digitizer to be adjacent to the transmitting digitizer, the receiving digitizer receiving reception signals produced by the transmitting digitizer, a receiving switch for receiving resulting signals, generated by the receiving digitizer in response to the reception signals, from a selective part or all of X- and Y-channels of the receiving digitizer, a channel controller for controlling the transmitting switch and the receiving switch, a data collection unit for collecting the resulting signals, and an analysis unit for analyzing the collected resulting signals.

Abstract: The present invention relates to an apparatus and a method for manufacturing a soft magnetic composite using ultrasonic vibration and a soft magnetic composite manufactured using the ultrasonic vibration. More specifically, the present invention relates to the apparatus for manufacturing a soft magnetic composite using ultrasonic vibration including: a die that has a putting-in space as an open space in which a powder material is put; a punch set that is inserted into the putting-in space and presses the powder material; an ultrasonic vibration applying unit including ultrasonic vibrators which are arranged along a circumference of an outer die surface of the die and are provided to come into contact with the die; a main body that is positioned below the die and is formed to slide around the die toward an outer circumference; and a control unit that controls a frequency of the ultrasonic vibrators depending on a degree of pressure of the punch set, a method for manufacturing a soft magnetic composite using ultrasonic vibration, and a soft magnetic composite manufactured using the same.
