Title: Lateral draft rolling mill
Inventor: TAZOE NOBUHIRO
IPC: B21B1/02
Filed: 1978-07-19
Abstract: PURPOSE:To improve the quality of a spread draft rolling mill by providing upper and lower quide rollers at a spread continuous casting slab to thereby prevent lateral buckling of the slab. CONSTITUTION:When a spread continuous casting slab 1 is laterally rolled by a pair of caliber rollers 3, buried surface pressure measuring instruments 4 detect the upper and lower vertical loads at the inside of the flanges projected from the rollers 3, and produce signals to a hydraulic unit to thereby operate hydraulic cylinders 7 at their rods. When the upper surface pressure at the inside flange of the roller 3 is higher than the lower surface pressure thereat at this time, both upper and lower guide rollers 5 are lowered to thereby push down the slab 1 by the upper guide roller 5. When both the upper and lower furface pressures become equal to each other, the operations of the cylinders 7 are stopped. When the upper surface pressure at the inside flange of the roller 3 is lower than the lower surface pressure thereat, both the upper and lower guide rollers 5 are raised to push up the slab 1 by the lower guide roller 5. When both the upper and lower furface pressures become equal to each other, the operations of the cylinders 7 are stopped to thereby reduce the width of the slab 1.

IPC: H03F1/30
Filed: 1992-04-09
Abstract: PURPOSE:To suppress output fluctuation of the automatic power control circuit due to its temperature characteristic which keeps a transmission level of a transmitter at a command power level from a base station. CONSTITUTION:Part of an output of a transmission power amplifier 1 is extracted by a coupling circuit 2 and the signal extracted from the coupling circuit 2 is inputted to an impedance converter 4 whose output impedance is set larger than an input impedance and an amplified output voltage from the impedance converter 4 is obtained from the input voltage. Then an output signal of the impedance converter 4 is detected by a detection circuit 5, a difference between an output of the detection circuit 5 and a command power level is amplified by an error voltage amplifier 7 and the amplified signal is used to control the amplification factor of the transmission power amplifier 1. Since the voltage signal is amplified by the impedance converter 4 before the signal is inputted to the detection circuit 5, output fluctuation of the transmission power amplifier 1 due to the temperature characteristic of the diode used for the detection circuit 5 is negligible.
