Title: Meandering control device for rapidly cooled thin metallic strip
Inventor: YUKIMOTO MASAO
IPC: B22D11/06

Abstract: PURPOSE:To advantageously prevent the meandering which is liable to arise at the time of transportation of the thin strip by providing detectors for both end positions of the thin strip, tension detector, meandering quantity computing element, etc., to the inlet side of a steering roll disposed between the rapidly cooled thin strip and a take-up reel. CONSTITUTION:The moving command of the steering roll 1 is given to a hydraulic cylinder 10 by the meandering control gain computing element 7 in accordance with the meandering quantity detected by the detectors 2 provided on the outlet side of pinch rolls 4. The positions at both ends of the thin strip 3 on the outlet side of the rolls 4 is detected 2 on the inlet side of the roll 1 and the signal difference from the detectors 2, i.e., the meandering quantity of the strip 3 is calculated 11. This meandering quantity and the predetermined permissible meandering quantity from a setter 13 are compared and computed 14. The result of the above-mentioned comparison and computation is inputted as the meandering deviation output to the computing element 7 which multiplies said output by an adequate gain to obtain a meandering correction signal. On the other hand, the tension signal from the detector 2 and the information signal on the sheet thickness, steel kind, etc., from an upper CPU16 are inputted to the computing element 7 and the moving quantity of the roll 1 is adjusted by making determination of the meandering correction signal corresponding to the respective experimental conditions, etc.

Title: Constant current circuit
Inventor: TAKASHIMA TETSUAKI
IPC: G05F3/22
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To operate a constant current circuit at a low voltage by utilizing the voltage between the base and emitter of a transistor in place of a Zener diode as a reference voltage. SOLUTION: When a current flows through a resistor 4 for current detection, a voltage is dropped, and when this voltage is higher than a voltage VBE between the base and emitter of a transistor 3 for reference voltage, the transistor 3 is turned on and operated in the direction for turning off a transistor 2 for constant current drive. Then, a current flowing through a load is reduced. Besides, when the current flowing through the resistor 4 is reduced and the voltage drop becomes lower than the voltage VBE between the base and emitter of the transistor 3, the transistor 3 is turned off, the base potential of the transistor 2 is dropped and it is operated in the direction for turning on the transistor 2. Then, the current flowing through the load is increased. Therefore, the current flowing through the load becomes a fixed value even when the voltage of a DC power source 1 is changed.
