Abstract: PURPOSE:To reduce crystalline grain diameter, to make carbides precipitate sufficiently, and to improve press formability by specifying the chemical composition of a steel and hot rolling conditions, respectively, and subjecting the resulting steel plate to reheating.and coiling under respectively specified conditions after coiling. CONSTITUTION:The steel has a composition consisting of, by weight, <=0.0050% C, <=0.8% Si, <=1.5% Mn, 0.015-0.15% Ti, <=0.0040% N, 0.010-0.090% Al, <=0.100% P, :0.030% S, and the balance Fe with inevitable impurities and containing, if necessary, 0.0003-0.0030% B. This steel is hot-rolled at a temp. not lower than the Ar, point and coiled at <=600 deg.C. The steel plate is reheated up to a temp. between Ar3 and (Ar3+30 deg.C) and held at this temp. for <=20sec. Further, the steel plate is cooled at <=(10 to 50) deg.C/sec cooling rate. Subsequently, cold rolling and continuous annealing are done. Because the necessity of rapid cooling directly after the completion of finish rolling is obviated, the control of hot rolling temp. conditions in the course between the completion of finish rolling and coiling can be facilitated.

IPC: H04L27/02
Filed: 1978-12-28
Abstract: PURPOSE: To obtain a recording and reproducing system of a small influence of modulation noise and the third harmonic wave distortion by forming a balanced modulation signal with the carrier suppressed to a prescribed value according to a pulse train and by subjecting this signal to low band conversion and by recording the converted signal.  
     CONSTITUTION: Pulse train signal SP coded by conversion circuit 2 is supplied to balanced modulator 3 and becomes signal SAM which is subjected to balanced modulation so that the middle of the level where the differential coefficient of signal SP is maximum may be non-carrier. Consequently, signal SAM is a signal of a small modulation noise and a good S/N due to balanced modulation, and further, this signal is a signal of a small influence of the third harmonic wave distortion due to suppression of the carrier. This signal SAM is processed by filter 5 for vestigial side-band and low-band conversion circuit 6, and signal SCL frequency-converted to the low band side is taken out from LPF 11 and is recorded together with a bias current, so that the third harmonic wave distortion can be reduced furthermore by recording of a good-linearity area.
