Abstract: Disclosed is an inductor including a core unit including an inner leg and an outer leg and a coil unit including a coil disposed spirally around the inner leg and a coil substrate on which the coil is disposed, wherein the coil has a width gradually increasing from the inner leg to the outer leg in a horizontal direction between the inner leg and the outer leg.

Abstract: This invention provides a circuit for generating a center point of a view finder comprising; a horizontal display-signal generation part 10 for generating the horizontal display-signal by adjusting the time constant of the monostable multivibrator IC1-IC4, a vertical display-signal generation part 20 for generating the vertical display-signal using 8-bit counter IC5 in which the horizontal drive-pulse is reset by the vertical drive-pulse, a center point display-signal composition part 30 for generating the center point display-signal by composition of the output of the horizontal and vertical display-signal generation parts 10 and 20, and a video signal composition part 40 for composition of the output of the center point display-signal composition part and the video signal and providing the composed output signal.
