In the continuous rolling mills, the strip crown and the strip flatness of a strip can be controlled to any desired value. In the strip crown measuring method, the strip crown of the first stage rolling mill can be obtained by adding the set target strip crown value and a value obtained by multiplying the deviation in mechanical strip crown between the predicted value and the actually measured value by a imprinting ratio. Further, the strip crowns of the second and after rolling mills can be obtained by adding the set target strip crown, a value obtained by multiplying the deviation in mechanical strip crown between the predicted value and the actually measured value by a imprinting ratio, and a value obtained by multiplying the deviation in entry strip crown between the target value and the calculated measurement value by an inheritance coefficient, for each rolling mill. Further, in the control method of the continuous rolling mills, the rolling mill is controlled in correspondence to the deviation in strip crown between the value actually measured by the profile gauge and the previously calculated value, in such a way that the manipulated variables of the actuators of the rolling mills arranged on the upstream side of the rolling mill having the profile gauge are equal to each other or determined to a predetermined proportion by use of imprinting ratios and inheritance coefficients.

The sheet profile of a strip on the outlet side of a final stand coincides with a desired value without deforming the shape of the strip, by using a hot strip finish rolling mill having a number of rolling stands disposed sequentially. The rolling mill employs feedback control of upstream stands to reduce the error between a sheet profile measured by a sheet profile meter disposed at the outlet side of a selected stand and a desired sheet profile. The selected stand is the stand where the sheet thickness of the strip is at the percentage sheet crown critical sheet thickness. The sheet profile measured by the sheet profile meter is used to control the downstream stands using feed-forward control to make the sheet profile on the outlet side of the final stand coincide with the desired sheet profile.

When drugs are prepared according to drug preparation order sheets printed by drug preparation order printers, it is desired to freely set the relation with the printers by setting data without directly connected and fixed to a control program of a control unit of a drug preparation order system so as to cope with e.g. relocations of drug preparation tables. As the drug preparation instruction system, a control unit and a plurality of drug preparation order printers are provided. In the data storage portion of the control unit, data showing the relation between drugs and drug types are stored. By reading drug type codes from inputted drug data, and by reading printer numbers corresponding to the respective drug type codes from a printer setting portion in which are stored data showing the relation between drug type codes and printer numbers, drug data are printed individually by the printers of the set numbers.
