PURPOSE:To increase the margin force for a stretcher, by using a converter for magnetic wall state. CONSTITUTION:A generator 56 is set to a major loop 41 to generate an intended runout magnetic field, and a magnetic wall state converter 52 is set at the front stage of a stretcher 53 and a detector 54 to convert the bubble magnetic domain into a state of a high runout magnetic field. A minor loop 31 and a transfer gate 51 are shown in the diagram. |
