Abstract: The present invention relates to a satellite antenna integrated time-synchronization device for generating a time-synchronization signal from a satellite signal received from a satellite, which includes a case, a 1PPS synchronization module which is disposed in the case and is configured to generate at least a 1PPS signal from the satellite signal, and a signal processing means which is disposed in the case and is configured to generate an IRIG signal and communication data using the 1PPS signal input from the 1PPS synchronization module.

Abstract: The disclosure relates to a permanent magnet actuator comprising: a stator iron core having a space therein-side, and having a first wall and a second wall opposing the first wall; a movable element moving reciprocally between the first wall and the second wall, along a moving axis which connects the first wall and the second wall inside the space; a first magnetomotive force supplying body and a second magnetomotive force supplying body disposed respectively on the first wall and the second wall, so as to supply a magnetomotive force to the movable element for the reciprocal movement thereof, wherein, at least one of the first magnetomotive force supplying body and the second magnetomotive force supplying body selectively produces a bidirectional magnetomotive force; a permanent magnet disposed between the first magnetomotive force supplying body and the second magnetomotive force supplying body, and providing a coercive force to the movable element for maintaining the state thereof; and a driving circuit co
