摘要： PURPOSE:To suppress variation in coil current low by providing a method of limiting the maximum voltage of a coil. CONSTITUTION:Between the driver circuit (composed of switching transistors 1 and 2 and driving voltage sources +E0 and -E0) and coil 4, diode 5 and clamp voltage source + or -E, and the clamp voltage source is controlled to a voltage of + or -E needed to flow a desirable current to the coil. As a result, the current amplitude of coil 4 depends only upon the clamp voltage source and is nearly under no influence of the total resistance of the resonance loop and driving voltage source. Namely, the variation in coil-4 current can be suppressed low.

摘要： PURPOSE:To realize the voltage clamp circuit less in power consumption, by delivering the clamp power absorbed and consumed in the voltage clamp circuit to other power consumption circuit. CONSTITUTION:The transformer 5 in which the winding ratio is equal to the clamp voltage to power supply voltage 9. Further, the power produced at the secondary is passed through the blocking diode 6, being consumed in the load 10. If the current I2 at the secondary winding is made less than the current I of the load 10, the current I2 is flown to the load 10 and the power supply 9 can be burdened only for the differential current of (I3-I2). That is, the clamp power essentially consumed in the voltage clamp circuit is consumed in the load 10 via the transformer 5, resulting that the clamp power is effectively used and the current capacity of the power supply 9, that is, the power consumption can be reduced.

摘要： PURPOSE:To hold an output released and prevent an operation error at the time of transition, by grounding the input terminal which becomes the reverse logical polarity to the output of the logical gate, through the resistance. CONSTITUTION:The input of the NAND gate 3 is held at a low level by resistance 2 at the time of transition when the electric power supply is closed and cut off. Accordingly, since the output of the NAND gate 4 is held at a high level, an operation error of the logical circuit can be prevented at the time of transition.

摘要： PURPOSE:To obtain a magnetic bubble memory device low in error rate and high in reliability by designating minor loops adjacent to checked-out defective minor loop as defective minor loops. CONSTITUTION:For minor loops 1-n-1, n, n+1-m, those circle marks shown in a figure are designated as normal minor loops, and cross marks are designated as defective minor loops. This way of designation is to designate, in addition to a defective minor loop (n) checked out by examination, two adjacent minor loops n-1 and n+1 as defective minor loops. By such a way of designation of minor loops, those minor loops which may heighten the error rate are skipped as defective minor loops and not used. Accordingly, the error rate of the device becomes low and the reliability is made high.
摘要翻译：目的：为了获得低错误率和可靠性高的磁性气泡记忆装置，通过指定与检出缺陷的小环相邻的小环作为有缺陷的小环。构成：对于小环1-n-1，n，n + 1-m，图中所示的那些圆标记被指定为普通次级环，并且交叉标记被指定为有缺陷的小环。这种指定方式除了通过检查检出的有缺陷的小环（n）之外，指定两个相邻的小环n-1和n + 1作为有缺陷的小环。通过这种小循环的指定方式，可以将可能提高错误率的那些次要循环作为有缺陷的小循环被跳过而不被使用。因此，装置的错误率变低，可靠性提高。
