Title: Distortion canceling circuit
Inventor: SAKAYORI KIJIO
IPC: H03F1/32
Filed: 1982-05-21
Abstract: PURPOSE:To cancel with high accuracy the distortions covering over a full control range of a voltage control amplifier VCA, by setting an emitter follower circuit to a feedback loop of an amplifier after setting the reference current at a proper level. CONSTITUTION:The signals of signal current source 5 and 6 are fed to an operational amplifier 3 via a VCA4 consisting of transistors (TR) Q1-Q4 having their amplification degrees controlled by the control voltage VC. An amplifier 9 consisting of TRs Q5-Q9 is connected to the side of a bias resistance Rb which uses a base diffusion resistance. A TRQ which impresses the reference bias to a reference current source 10 and the amplifier 3 is connected to the amplifier 9 via a filter consisting of a capacitor C1 and a resistance R1. The current of the TRQ is coincident with the current of the source 10 owing to the function of the amplifier 9 and constant over a full control range of the voltage VC. As a result, the secondary distrotion is cancelled for an output signal e0.

Filed: 1982-05-24
Abstract: PURPOSE:To stop a barrel in the home position, by detecting that a close-up lens is placed on the photographic optical path, and making the distance measurement of an auto-focus device impossible or limiting the extension of the barrel. CONSTITUTION:When a close-up lens 13 is turned in the direction of an arrow 11 and is set in a mount 12, a gear 8 is rotated against a spring 10 because a pin 9 is pressed by a projection 14 of the close-up lens 13.
