Abstract

PURPOSE:To enable small size and low cost, by constituting the mounting blade supporting the magnetic bubble elements with the magnets for bias magnetic field generation of conductivity. CONSTITUTION:The magnetic bubble crystal 6 is placed at the crossing part of the X coil 3 and the Y coil 4, and this crystal is placed on the bias magnet of conductivity. Further, the bias magnet 12 is located at the upper part of those. With this constitution, by only providing the coil plate 5 on one side of the magnetic bubble crystal 6, almost the same operating effect as the case of provision for the both sides, can be obtained. Further, small sized and lower cost unit can be possible accompanied with the reduction in number of components to make easy the assembling works. Further, terminals can be provided on the entire circumference of the crystal 6. Moreover, since the crystal 6 is directly mounted on the magnet 13, heat dissipation effect can be assisted to restrict the temperature rise of the crystal 6.
