Filed: 1978-12-28
Abstract: PURPOSE: To make the pass characteristic of plate stable and make control effective by determining the maximum value of plate crown control amount based on shape blind zone and distributing the control amount within that range thereby performing the plate crown control.  
     CONSTITUTION: In rolling, the deformation resistances obtained from the width, thickness, steel kinds, temperature, etc. necessary for determining shape absolute blind zone are sent to a setter 9 by the signal from a rolling condition operating setter 8. From these values, the blind zone is operated by an arithmetic unit 10. Next, from this value, the maximum value of plate crown control amount is determined and within this range the control amount is distributed to the double chock work roll bending devices 7 of the respective stands. In this case, the degree of permissible shape is larger as it goes toward the upper stream stands and therefore the practicable blind zone may be widened and the plate crown control amount in the upstream stands may be correspondingly increased.

IPC: G01L1/12
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To correctly and stably measure a loadage and a weight of a vehicle and improve measurement accuracy by taking out load detection signals while impressing an excitation power source to a magnetostriction sensor as ON/OFF switching pulses. SOLUTION: A switching circuit 45 is interposed between each magnetostriction sensor 7 and a power source 44 feeding power to an excitation coil of the sensor, which impresses a switching pulse voltage in the form of ON/OFF pulses. An ON pulse is twice a measurement timing pulse, e.g. 4 seconds. An OFF pulse is the same 2 second as the measurement timing pulse, but shifted one second to the measurement timing pulse. One invalid detection output (voltage level 0) and two valid detection outputs (voltage output corresponding to a load) are obtained every one pulse cycle. Whether a sensor output taken via an amplifier 41 is 0V or not is detected every measurement timing, and outputs other than 0V are sampled as valid detection outputs and operated in a predetermined process.
