PURPOSE:To attain a stably operating block replicator, by providing a hairpin- shaped conductor pattern over a cusp of a major line from a cusp of a minor loop on the line connecting the cusp of the major line and the cusp of the minor loop. CONSTITUTION:A conductor pattern 12 is formed into a hairpin shape over a a cusp 10a of the major line from a cusp 11a of the minor loop. When a bubble 14 is transferred to the cusp 10a of a minor loop 11 as shown in Fig. (a), a pulse I1 is impressed to the conductor pattern 12 in the direction where the bubble is striped. Thus, the bubble 14 is expanded on the inside of the hairpin- shaped conductor pattern 12 over the cusp 10a of the major line as shown in Fig. (b). Next, when a pulse I2 having an opposite polarity is impressed, the bubble is cut into bubbles 14' and 14'' in a non-implantation area between cusps 10a and 10b of major lines as shown in Fig. (c). Consequently, the bubble is not trapped halfway. |
