  • Airburst munition and airburst signal transfer device
    Patent number: 11067373
    Abstract: Disclosed are an airburst munition and an airburst signal transfer device. By simply signaling information regarding a distance to an explosion location of the airburst munition to an explosion control system inside the airburst munition while the airburst munition passes through a tubular body of the airburst signal transfer device, it is possible to easily, simply, and automatically enter the information regarding the distance to the explosion location of the airburst munition to the airburst munition using the airburst signal transfer device.
    Type: Grant

  • Apparatus and method for searching eddy current of electric heat tube using measuring magnetic permeability in steam generator
    Patent number: 8283918
    Abstract: A detection apparatus for an eddy current in a heat generating tube using a permeability measurement method, and a method using the apparatus are provided. In the detection apparatus, a bobbin type probe acquires detection information with respect to a magnetic flux change by a magnetic phase occurring in the heat generating tube using a coil which is wound in an axis direction of at least one yoke located in a perpendicular direction with a bobbin of the bobbin type probe, and a material having a corresponding magnetic phase and a circumferential defect, which is difficult to be detected by the bobbin type probe, are detected based on the detection information.
