Title: Hot rough rolling method
Inventor: SHIBATA TOUSHI
IPC: B21B1/00
Filed: 1985-09-14
Abstract: PURPOSE:To assure specified quality for a post stage and to quickly detect the abnormality of a prestage in rough rolling of steel products, more particularly steel ingot by comparing the results of the comparison between the driving power consumption of each pass of rolling mills and the reference value of the time required for rolling with an abnormal pattern. CONSTITUTION:The rolling mills 2, 1 respectively have, for example, 2, 4 passes. The material of approximately the prescribed temp., size shape and weight is fed to the former. The driving power consumption P, rolling start and end time T and material weight W of a mill motor 3 is converted to a digital value by an analog-to-digital converter 5 and is continuously inputted in real time to a CPU 6. The driving power consumption and rolling time required for rolling per unit weight in each pass are calculated in this stage and the corresponding reference rolling pattern of a disk file 7 is called by a keyboard 8 to the CPU 6 which compares the calculated values with the respective reference values. The CPU identifies whether said pattern corresponds to which abnormal pattern and displays the same on a display device 9 if there is the abnormality in the driving power consumption of the rolling in each pass.

Moreover, though the base currents of the PNP switching transistor 10 are determined by the resistance value of a resistor 26 and the voltage across it, the voltage across the resistor 26 is the value that the voltage between a base and an emitter is subtracted from the base voltage of the NPN transistor 25 and since it does not fluctuate, it can be stabilized with no adjustment. Furthermore, by the insertion or removal of a DC plug 17, the terminal in contact with the cathode of a DC jack 18 is turned on or off so as to control the cathode of a charge-type battery 3.

Abstract: PURPOSE:To enable stable detection of torque with a high output and a high S/N ratio while facilitating mounting in a small space, by fixing magnetic thin metal strips each imparted magnetic anisotropy partially in a pair on the same circumference of a torque transmission shaft circumferentially to arrange a detection magnetic core differentially connected to a detection winding in proximity thereto. CONSTITUTION:A pair of magnetic thin metal strips 221 and 222 are fixed with an adhesive at two points shifted by 180 deg. on the same circumference of a torque transmission shaft 21 circumferentially. A large induction magnetic anisotropy KU' is imparted to the thin metal strip 221 in the direction inclined by an angle thetato the circumferential direction X of the shaft 21 while to the thin metal strip 222 in the direction inclined by -theta thereto. On the other hand, detection magnetic cores 231 and 232 are provided with excitation windings 241 and 242 and detection windings 251 and 252, which are connected differentially. Thus, as one pair of the detection magnetic cores 231 and 232 are arranged on the same circumference, less width thereof is required for the mounting and as the detection of a torque is done partially in the circumferential direction, there is less effect of non-uniformity in the material of the shaft 21.

IPC: B41J2/335
Filed: 1984-09-28
Abstract: PURPOSE:To reduce the irregularity in the resistance value of the heat generating resistor of a thick film type thermal head, by reducing the resistance value by applying a voltage pulse to the heat generating resistor. CONSTITUTION:The initial setting of pulse condition such as the peak value Vs of apply voltage or the number (n) of pulses is performed by a calculation part 12. Next, the above mentioned set pulse is applied to a thermal head 7, of which the resistance value is equal to or more than a predetermined value R0, from a pulse generation circuit 10 and, thereafter, the resistance value of the above mentioned thermal head 7 is measured by a resistance meter 11. Then, the preceding measured value is compared with the lately measured value and, if the lately measured value is low, said value is compared with the adjusted objective value R0 and, if it reaches R0 or less, the peak value Vs of an apply voltage pulse is increased by DELTAV to apply voltage. When the peak value is further increased in the same way, the peak value Vs is increased by 2DELTAV. As mentioned above, the peak value is successively increased to apply voltage and the ratio of each pulse width DELTAt and a pulse cycle T is changed so as not to destruct the heat generating resistor to adjust the resistance value to R0 or less and the irregularity in the resistance value is reduced.

Filed: 1989-08-08
Abstract: PURPOSE:To prevent the lowering of accuracy by alternately applying a reference signal and a measuring signal to two signal processing circuits to repeatedly detect phase difference and calculating the distance up to an object from the average value of the detection data. CONSTITUTION:A measuring part 13 repeatedly detects the phase difference between the inputs from respective signal input parts 13A, 13B, that is, a measuring signal and a reference signal. Thereafter, by averaging a predetermined number of detection data, the temp. drifts or time drifts of the phase characteristics in respective signal processing circuits 12A, 12B are set off and the distance (l) up to an object is calculated on the basis of the average value. As mentioned above, since the distance up to the object is calculated from the average value of the detection data, even when separate temp. drifts or time drifts are generated in the phase characteristics of the transmission functions in the respective signal processing circuits, the drifts are set off and the lowering of accuracy is prevented.
