Title: Method for controlling meandering in plate rolling
Inventor: YAMADA KENJI
IPC: B21B37/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent tail choking or rapid meandering of a rolling stock in tandem rolling, by estimating difference between the left and right of tension between rolling mills and controlling the draft set value so that the difference becomes zero. SOLUTION: In tandem rolling, sampling is done at the same point of time during the rolling on the roll circumferential speed of each rolling mill, draft set value on the working side and the driving side, and detected value also on these two sides of a rolling stock tension measuring device installed between the mills. On the basis of these sampling data, difference between the left and right (L/R difference) of tension is estimated between the mills actuating on the rolling stock. In order to make this L/R difference of the tension zero, the manipulated variable is determined for the L/R difference of the draft set value for each mill, using the equation system in the stationary time of tandem rolling. On the basis of this variable, controlled is the L/R difference of the reduction set value of each mill.  In addition, as necessary, in estimating the L/R difference of the tension between the mills, data are added for the plate thickness measured at two points or more in the width direction of the plate, on the entrance and exit side of the line of the mills and at three places or more between the mills.

Title: Current switching type logic circuit
Inventor: TAKAHASHI TORU
IPC: H03K19/086
Filed: 1988-08-08
Abstract: PURPOSE:To effectively detect a defective speed by giving an emitter output of an emitter follower transistor(TR) to a base of a reference side TR of a current switching type logic circuit via a high resistor. CONSTITUTION:When a bias current to an output TR Q4 is not made flow because of a failure in the connection to a resistor R3 due to any cause, a potential of an output OUT is clamped to a voltage VREF via a resistor R4. Since the current flowing to the resistor R4 is an input current of a load gate connecting to the next stage and very less, the voltage drop at the resistor R4 is almost zero and the potential at the output OUT is clamped almost equal to the voltage VREF. Thus, when any fault takes place to the connection to the resistor R3, since the output OUT surely malfunctions the gate of the next stage, the defect of speed caused due to the abnormality of the termination resistor is easily detected.

Title: Soft magnetic material
Inventor: SHIMADA HIROSHI
IPC: C22C45/04
Filed: 1982-11-13
Abstract: PURPOSE:To obtain a soft magnetic material having high permeability and saturated magnetic flux density by restricting total contents of Zr and Nb in an amorphous alloy of three element system of Co-Zr-Nb. CONSTITUTION:A total content of Zr and Nb is restricted to the range of 5- 20wt% in the three-element amorphous alloy adding a little amount of Zr and Nb to the main element Co. Namely, when a total content of Zr and Nb is within the range of 5-20wt%, a high permeability mu can be obtained but if it is out of such range, a value of mu reduces. When a total content of Zr and Nb exceeds 20wt%, saturated magnetic flux density reduces rapidly. Accordingly, a soft magnetic material having high permeability and saturated magnetic flux density can be formed by restricting a total content of Zr and Nb.
