PURPOSE:To prevent that a magnetic bubble generator operating current becomes a noise of detector operation by detaching the operation timing of more than a pair of magnetic bubble detector and magnetic bubble generator which belong to a different major transfer line, to at least 1 period or above of the revolving magnetic field periods. CONSTITUTION:In an even and odd minor loop group system magnetic bubble elememt, respective groups of magnetic bubble detectors are operated every other period of the revolving magnetic field and the same group of the magnetic bubble generator is operated every other period of the revolving magnetic field. Namely, the odd minor loop group of the detector 21 (D1) and the even minor loop group of the detector D2 (22) are operated in the period (timing) of the same revolving magnetic field, or, just one period of the operation timing of the magnetic bubble generator is dislocated from that of the detector operation timing in the same minor loop group. Consequently, for the odd minor loop group of the detector 21 (D1) and the even minor loop group of the generator 32 (G2) which are arranged nearby each other, the operation timing causes just one period dislocation of the revolving magnetic field, D1 will not be influenced by the noise occurrence due to G2 and the malfunction of the detector is removed. |
