Title: Amplifier circuit
Inventor: OTA GENICHIRO
IPC: H03F3/26
Filed: 1990-11-27
Abstract: PURPOSE:To allow the amplifier circuit to be operated at a high speed even to any of a rising signal and a falling signal by outputting an output of each collector of two common emitter amplifiers to a common output terminal and feeding back an output signal of the output terminal negatively to other input terminal of a 2nd differential amplifier. CONSTITUTION:A positive phase sequence and an opposite phase sequence of an input signal (a) are individually amplified by a 1st differential amplifier comprising NPN transistors(TRs) 4, 6 and a 2nd differential amplifier comprising PNP TRs 5, 7. Then an opposite phase collector output of each differential amplifier is inversely amplified by a grounded-emitter amplifier comprising TRs of opposite polarity type to that of TRs being components of the differential amplifier. Thus, each stage from the input stage till the output stage is formed to be of emitter-grounded type, which is realized by the combination of NPN and PNP TRs to eliminate a DC voltage component. Thus, the amplifier circuit is operated at a high speed to both the rising and falling signals.

The amt. of cooling water to be sprayed from the nozzle 7c arranged on the upper face is controlled by a cooling water control means based on the obtained relation with the cooling water amt. from the nozzle 7c on the lower face as a reference. At the same time, the amts. of water to be sprayed on the upper and lower faces are controlled so that the temp. difference between the upper and lower faces of the sheet 1 is kept at a value lower than the predetermined allowable value. Accordingly, since the temp. difference between the upper and lower faces of the sheet 1 at the time of cooling is kept at a value lower than the predetermined value in this way, the cooling rate of the sheet is uniformized, deformation in cooling is prevented, and a quality symmetrical in the thickness direction is obtained.
