Title: Linear power amplifier
Inventor: MORIOKA SUSUMU
IPC: H03F1/02
Filed: 1987-01-13
Abstract: PURPOSE:To realize the amplification with high efficiency without causing any switching distortion by introducing the digital processing in switching the power voltage of a power amplification stage according to the amplitude of an input signal in an amplifier amplifying the input signal while applying D/A conversion. CONSTITUTION:A digital input signal Sd is formed into an analog signal Sa after passing through a delay circuit 11 and fed to a power amplifier stage 15. Rectifier circuits 24, 25 output respectively positive/negative voltages VH, VL and -VL, VH. The MSB and 2SB of the signal Sd are fed to AND circuits 41, 51 for detecting the amplitude and AND outputs Sp, Sn are obtained. Since the signal Sd is an offset binary code, the relation between the value of the signal Sd and the amplitude of the signal Sa, the relation between the signals Sp, Sd and between the signals Sn, Sd are as shown in figure (a). In a switching circuit 31, a voltage VL or VH is supplied to a transistor Q1 as the operating voltage with Sp='0' and '1' and a switching circuit 32 is operated similarly with Sn='0' and Sn='1'. Thus, the voltage +VH or -VH is supplied to the amplifier stage 15 only with Sa>=4 and Sa<=-5. Moreover, since the voltage switching is not delayed with respect to the signal Sa in the amplifier stage 15 because of the intervention of the delay circuit 11, no distortion is caused at switching.

Title: Feeding method for rolling mill oil in hot rolling
Inventor: KOUNO TERUO
IPC: B21B45/02
Filed: 1978-01-23
Abstract: PURPOSE:To prevent the wearing and injury of the roll and also to reduce the mill load, by feeding the oil to the roll so as to make larger the breadth of spray in the rolling direction against the surface of the reduction roll than the value of product of the real time of spray and the peripheral speed of the roll, in the case of feeding the mill oil to the hot rolling. CONSTITUTION:In feeding the mill oil to the roll surface for the hot rolling, if the temperature of the steel sheet rises up for instance, the sticking property of the rolling mill oil reduces down. Besides, the sticking property of the mill oil increases with the length of the time of spray against the rotary roll; for instance, when the real time of spray exceeds 0.014 seconds, the sticking property increases suddenly.  In the meantime, when the shape of the oil feed nozzle is a full-cone type 33, the breadth a of its spray is larger than the flat type, and as a result, the real time of spray becomes so longer that the quantity of sticking mill oil is doubled. Accordingly, the wearing and injury of the roll are prevented and also the mill load is reduced, by making larger the breadth of spray in the rolling direction than the product of the real time of spray and the peripheral speed of the roll.
