| 英文摘要 | PURPOSE:To stabilize the control speed of an optoelectric negative feedback loop accurately at a high speed with high resolution. CONSTITUTION:A light emitting level command signal current is transmitted from the drain of a field effect transistor 3 to an amplifying stage made of a transistor 5 through a voltage shifter 4 by a current amplifier of an optoelectric negative feedback loop. |
