The invention relates to a circuit arrangement with a transfluxor, which is particularly useful for the construction of memory circuits, logical networks and the like. The use of the transfluxor in such circuits are known. It has the advantage that the memory content of the transfluxor is non-destructive is readable. But it also brings with it a number of difficulties caused by the mode of action of the transfluxor.

The transfluxor in its simplest form consists, as FIG. 1 shows, of a ferrite core 1 with two bores 2 and 3 through which the yokes I, II, III are formed. The dimensions are usually chosen so that the cross section of the yoke I is equal to the sum of the cross sections of the yokes II and III. The yoke I carries at least one control winding S via which the transfluxor can be adjusted or blocked. However, separate control windings for "setting" and "blocking" can also be provided. The yoke III carries a retrieval winding e and an output winding a. The Transfluxor only supplies an output signal when it is set, but not when it is blocked. The query can be made by means of an alternating voltage or by supplying individual pulses of alternating polarity.

The mode of operation of the transfluxor is based on the interaction of the two holes 2 and 3 surrounding magnetic circles. In the blocked state, the core material is in all three yokes in the same remanence point, resulting in a saturation of the circle around the hole 3 with makes yokes II and III impossible. The circle around the hole is used to adjust the transfluxor 2 partially saturated. In the set state, the core material in yoke I is partly in that one, partly in the other remanence point, while in yokes II and III opposite remanence states to rule.

The transfluxor is therefore a flow-sensitive component.

It is clear that the setting of the transfluxor high demands on the dosage of the current which is to be fed to the control winding. This is especially true when in the applications as well the temperature influence must be taken into account, since the temperature dependence of the coercive force affects the setting accuracy.

It is now also possible to change the flow required for setting by applying to effect a certain voltage-time integral, as it is, for. B. in the gradual setting of counting chokes is common. Here, too, the influence of temperature has a disadvantageous effect.

The invention is now based on the object of a largely temperature-sensitive, of a special dimensioning of the currents or pulses required for operation, independent circuit arrangement to create with Transfluxor, in particular for the construction of memories, counter cores and Shift registers is suitable.

According to the invention, this object is achieved in that a magnetic core with a rectangular hysteresis loop is provided as the drive core for setting the transfluxor and is connected in such a way that saturation pulses can be fed to an input winding of the driver core, and that an output winding of the driver core with an expensive winding of the transfluxor forms a closed circuit in at least one current direction, so that this control winding is supplied with a constant voltage-time integral at least when the driver core is unsaturated. With regard to temperature compensation, driver and transfluxor cores made of the same material are advantageously used. In order to effect the adjustment of the transfluxor by only one saturation of the driver core, the dimensions of the cores are expediently chosen so that the product of cross section and number of turns for the driver core is half as large as for the transfluxor. If the setting is only to be effected by η resaturation of the driver core, the circuit, on the other hand, must be dimensioned in such a way that the products of cross-section and number of turns formed for the transfluxor and driver core behave as 1: 2 η.

The circuit arrangements according to the invention are particularly useful for constructing shift registers suitable. Such shift registers can

of such a small amplitude causes this for the Transfluxor remains ineffective.

Fig. 3 shows such a circuit arrangement. The cores Kl and K 2 again carry the same windings as in FIG. 2, only that the output winding α 2 of the transfluxor is omitted here. A capacitor C is connected in parallel with the input winding W1 of the driver core, one document of which is connected directly and the other document via the diode D to the terminals of the feeder e 1 .

It is again assumed that in the initial state the driver core K1 and the transfluxor K 2 are in the state of negative remanence. If an alternating current source with a small internal resistance is now applied to the feed line e 1 , the capacitor C is charged by this via the diode D. In the process, a direct current gradually sets in at the winding Wl , through which the core Kl is relatively slowly resaturated. After switching off the alternating current source at el, Kl remains in the state of positive remanence. During the saturation of the core K1 , a current that is proportional to the change in flux άΦ / dt flows in the coupling loop formed by the windings W2 and S1. This is so small that nothing changes in the remanence state of the transfluxor, so it remains blocked. If the driver core is now returned to its initial state by a powerful pulse via the input winding WZ , an output pulse is transmitted from W2 to S1 and the transfluxor is set. When the transfluxor is blocked again, it must be ensured that its return to the state of negative remanence does not affect the driver core K 1. It is therefore advantageous to limit the reset current supplied to the S expensive winding S2 so that the flux change occurs only slowly during resaturation and only correspondingly small currents are induced in the coupling loop between if 1 and K 2. If the blocking of the transfluxor is also to be operated with powerful pulses, the reaction of the transfluxor on the core K1 must be limited accordingly by a corresponding attenuator in the coupling loop between W 2 and S1 , for example by taking a high voltage time integral at the output of Kl and feeds only a fraction of the same to the setting ^{winding 6 1} 1 of the transfluxor, so that conversely the voltage-time integral delivered when S1 is blocked is only transferred to a small part on winding W2 .

In the set state, as in the circuit arrangement according to FIG. 2, when an alternating voltage is supplied to the retrieval winding e, a useful signal can be taken from the transfluxor via the reading winding α.

4 to 7 show different exemplary embodiments for the construction of shift registers from circuit arrangements according to the invention. The shift register shown in FIG. 4 is made up of circuit arrangements according to FIG. A driver core and a transfluxor are provided for each register stage, two of which are shown in FIG. 4. According to a further development of the invention, the output winding α 2 of the transfluxor of one stage is connected to the input winding Wl of the driver core of the next following stages via a diode Gl that is permeable in the slide direction. The control winding S2 of the transfluxors and the input windings WZ of the driver cores of all stages are each connected in series and connected to two switching lines p 1 and p 2 .

This circuit is operated so that the projections switching pulses alternately switching the progress lines PL and is supplied to p 2 are. In this case, all transfluxors are blocked at the same time by a first switching pulse on line p1. If one of the transfluxors was in the set state before blocking, an output signal from the output winding α 2 of this transfluxor is transmitted via the rectifier G1 to the input winding Wl of the subsequent driver core and the information previously stored in the transfluxor is transferred to it. The driver core is then folded back into its initial state by the subsequent second stepping pulse via the line ρ 2 and an output signal is transmitted via the diode G to the next following transfluxor, whereby it is stopped. If, for example, the transfluxor K 0 was in the set state before the blocking, then KO is blocked by the first incremental pulse and the driver core Kl is resaturated. The second stepping pulse saturates Kl and the transfluxor K2 is set. If, on the other hand, KO was not set before blocking, the first stepping pulse, which z. B. K2 blocked, no change in flow in KO and thus no saturation of Kl, so that when the. second incremental pulse is fed to line p 2 , Kl can no longer be resaturated and therefore also does not emit an output signal for setting K2 .

As a result of the incremental pulses on lines p 1 and p2 , the stored information is alternately transmitted from the transfluxors to the driver cores and from these again to the subsequent transfluxors. The information is picked up at the Transfluxor when the Transfluxor is blocked.

However, the circuit can also be designed in such a way that the information is picked up at the transfluxor at the same time as the useful signal (read signal) is extracted. A correspondingly designed shift register is shown in FIG. 5. In this, too, a transfluxor and a driver core are provided for each register stage, the circuit arrangement of which corresponds to the circuit according to FIG. The coupling of the individual stages is designed in this embodiment according to the invention so that in each case the reading winding α of the transfluxor of one stage is connected to the supply el of the driver core of the next stage and that each of the S expensive windings S 2 of the transfluxors and the input windings W2 of the driver cores of all stages are connected in series to a switching line p 1 or p2. To operate this circuit, a first step-up pulse is fed to one step-up line p 1 to block the transfluxors of all stages and then a second step-up pulse to the other step-up line p 2 to query the driver cores and set the transfluxors accordingly.

So that no information is lost between two successive incremental processes, it is necessary to supply an alternating voltage to the input or retrieval windings e of all transfluxors in order to take a useful signal on the output side via windings a on the one hand and to adjust the direct current via diodes D and capacitors C and windings Wl on the other the

Make driver cores. So this circuit will mainly be used when the Applications, a reading pulse follows each stepping process.

According to a further development of the invention, the coupling loops between the driver core and the transfluxor can also be designed in such a way that the shift registers constructed from the transfluxor circuits can be operated with only one switching line. For this purpose, it is advantageous to switch on a delay element LC in the coupling loop between the output winding W 2 and the control winding Sl after the rectifier G. FIGS. 6 and 7 show correspondingly constructed shift registers. In the shift register according to FIG. 6, which is designed for pulse setting of the driver core, a delay element LC 1 is connected in the coupling loops behind the rectifiers G and a delay element LC 2 is connected behind the rectifiers Gl. The control windings S 2 of the transfluxors and the input windings WZ of the driver cores are alternately connected in series and form a common switching line p. By supplying incremental impulses, all transfluxors are blocked at the same time and all driver cores are queried. If a transfluxor was in the set state before blocking, an output signal is input to the downstream delay element LC 2 via G 1 and, after the switching pulse has decayed, stored in the subsequent driver core. If, on the other hand, information was stored in one of the driver cores, the incrementing pulse generates an output signal which is input via diode G into the downstream delay element LCl, and which, after the incremental pulse has subsided, the setting of the subsequent transfluxor via the expensive winding 5 " 1 causes.

Such a shift register according to the invention can in principle be operated in two different operating modes. The first requires two incremental pulses for each incrementation process, which are fed to incremental line p one after the other. The driver cores only serve as auxiliary cores or temporary storage, while the actual useful information is only stored in the transfluxors. The entire useful information is then transmitted from the transfluxors to the driver cores by the first incremental pulse and then again from the driver cores to the transfluxors in a second incremental cycle. The information content of all transfluxors is zero after the first increment pulse and after the end of the storage process delayed by the delay elements, and the information content of all driver cores is zero after the second increment pulse. In this mode of operation, the shift register works with one driver core and one transfluxor per bit.

In a second mode of operation, this shift register can also be operated in such a way that one bit is stored per driver core and per transfluxor. In the case of a shift register according to FIG. 6, only every second bit can then be read non-destructively. In principle, such a shift register corresponds to a shift register with normal cores, in which one core is also provided for each bit. In many cases there is no requirement for readability for every level of the register. Often only the reading in the last register level is required. In other cases, for example in the binary multiplication of binary numbers represented in series by a factor of 10, it is only necessary to use the nth. and interrogate the (n- 2) -th register level. In this case, transfluxors will only be used in these two stages instead of normal nuclei. In this form, the circuit arrangement according to the invention can be used wherever the reading points are not in directly adjacent register levels.

A further embodiment with only one switching line is shown in Fig. 7. In this shift register, a delay element LC is also switched on in the coupling loop between the core and the transfluxor behind the diode G , while the direct current setting of the driver core is carried out in the same way via the output winding of the transfluxor of the previous stage as in the shift register according to FIG. 5. Here, too, a driver core and a transfluxor are provided for each register stage, that is to say for each bit. Between two successive incremental pulses, the transfluxor has to be supplied with a request signal via the input winding e so that no information is lost, otherwise the transfluxor will only be blocked by the incremental pulses and the information "0" will be retrieved from the driver cores, but not the information previously stored in the transfluxor Information is transferred to the driver core. Shift registers of this type are particularly suitable where each incremental pulse is followed by a read pulse.
