PURPOSE:To obtain a magnetic bubble divider which has stable working with small power consumption, by having a constricted form for the belt-shape part of the 2nd conductor at the cross part of the 1st and 2nd conuctors. CONSTITUTION:As shown in the figure, the 2nd conductor 5 has the constricted parts 52 and 53 with the reduced widths. Therefore a current density is increased at these parts 52 and 53 compared with other areas when a current is impressed to the conductor 5. As a result, an extremely large mganetic bubble cutting magnetic field is generated at the cross part of the conductor which is held between the parts 52 and 53. While the current density is small at the areas other than the conductor cross part, and therefore an undesired generated magnetic field is reduced. That is, the effect of a cut-off current is extremely reduced compared with a conventional case for the magnetic bubble existing at a stable position 22, etc. regardless of division of the bubble. In addtion, it is possible to obtain a fixed magentic bubble cutting magnetic field with the current value smaller than a conventional one. |
