Title: Demodulating circuit
Inventor: OGAWA FUMIO
IPC: H04B10/07
Filed: 1987-04-17
Abstract: PURPOSE:To improve the S/N by constituting the titled circuit by an envelope detector extracting a detection output from a common emitter connecting an envelope detection capacitor and a waveform shaping device waveform-shaping the output of the detector. CONSTITUTION:An amplitude modulation wave superimposed with a noise component N1 on one base and only the noise component N2 is inputted to the remaining base and when a control signal is an amplitude modulation wave corresponding to 0, the input noise is subject to envelope detection by a diode and a capacitor C1 between the base and emitter of transistors(TRs) Q1, Q2, added at the emitter simultaneously and the noise component (N1+N2) is extracted. When the control signal is an amplitude modulation wave corresponding to 1, however, the modulation wave is subject to envelope detection by the diode and the noise component N2 entering the remaining base is shut off because the diode is reverse-biased and not outputted to the emitter. Thus, in case of the amplitude modulation wave where the control signal is 1, the noise component N1 inputted to the other base is not added and the S/N of demodulation signal is improved.

IPC: B21B37/00
Filed: 1993-04-22
Abstract: PURPOSE:To restrain a steel sheet from walking and to prevent a roll mark flaw by controlling an electric current command in a ramp shape with a main controller to control the tension of a tension reel. CONSTITUTION:In a manufacturing line where the steel sheet is passed and wound by the tension reel 3, when the tension is changed by using a main controller 10 controlling a tension of the tension reel 3 driven to control the tension of the steel sheet, the electric current command is controlled in a ramp shape, sharp increase of tension of the steel sheet in contact with the roll of a pinch roll leveler 2 and walk of the sheet due to shortage of the tension when the steel sheet is accelerated is restrained. In this way, since the electric current command is controlled in the ramp shape, the tension given to the steel sheet is changed gently. Consequently, when the tension is changed, a sharp increase of tension can be prevented from occurring on the sheet and the walk of the sheet due to shortage of tension in acceleration can be restrained.
