Title: Tension controller in process line for ferrous material
Inventor: DAIHO HIROSUKE
IPC: B65H23/192
Filed: 1978-05-08
Abstract: PURPOSE:To set the gain correspondingly to the sheet size, and to improve the accuracy of control, by installing the circuit for adjusting the gain of the tension control system against the size and material of the sheet. CONSTITUTION:The gain adjusting circuit 8 uses the set tension value as the sheet size signal. The set tension value is gaven as the input of the electrically-driven potentiometer MRH through the amplifier 3A; the potentiometer 2RH 1 is for the feedback of the electrically-driven potentiometer MRH, and the potentiometer 3RH is for the bias. The potentiometer 2RH 2 is interlocked to the potentiometer 2RH 1, and is combined with the amplifier 2A to constitute the dividing circuit. The output of the amplifier 2A is made by equivalently dividing the output of the amplifier 1A by the sectional area of the strip. Thus, when the sheet size is large, the gain of the tension control system is reduced inverse-proportionally to the sheet size; and when the sheet size is small, the gain of the circuit increases inversely to above.

Filed: 1984-03-23
Abstract: PURPOSE:To exclude a system bus control part and to attain the high-speed transfer of DMA by separating a direct memory access DMA memory part from a main memory part and adding a DMA separating part. CONSTITUTION:When main control parts 1 and 2 supply indications to a DMA control part 6 for permission of start of DMA transfer, the part 6 outputs a separating indication to a DMA separating part 12 through a DMA separating line 14. Thus the part 12 separates a common system bus 8 from an internal bus 13, and the part 6 controls the DMA transfer via the bus 13. The end of the DMA transfer is informed by the part 6 through an individual line connected to the parts 1 and 2. Then the part 6 feeds an indication to the part 12 for release of the bus separation. While the parts 1 and 2 know a DMA transfer state via the bus 13 and therefore supplies no access to a memory part 11, etc. via a bus 8. This improves the processing capacities of the parts 1 and 2 and to omit a system bus control part and to increase the DMA transfer speed.
