Title: Binary-coding weighting constant current source circuit
Inventor: YOKOYAMA KENJI
IPC: H03M1/80
Filed: 1983-02-08
Abstract: PURPOSE:To attain the operation at a low voltage and to obtain an output current with high accuracy by providing n-set of differential transistor (TR) pairs and connecting mutually current paths comprising the 1st current mirror circuit inverting one collector output current of the pair of the pre-stage and the 2nd current mirror circuit inverting again the output current and supplying it to a common emitter of the pair of the next stage. CONSTITUTION:A current I flowed to the common emitter of TRs 9-1, 10-1 in the differential TR pair 7-1 is divided equally into I/2 and each is outputted from each collector. Then, the collector output current I/2 of the TR 10-1 is converted into other current I/2 of the same current value at a current mirror circuit 13-1 and extracted from the collector of a TR 16-1. Similar operation is repeated thereafter. Thus, collector output currents I/2, I/2<2>...I/2<8> of the other TRs 9-1-9-8 in pairs 7-1-7-8 are extracted selectively via switches 23-1-23-8 driven in response to inputted binary information, then an output current i0 having a value corresponding to the binary information is obtained at an output terminal 26.

Filed: 1979-02-21
Abstract: PURPOSE: To make the finder bright and prevent the out-of-focus of the finder and film plane by leading only the infrared light to the distance measurement system through the use of a dichroic mirror.  
     CONSTITUTION: The light incoming from the subject through an objective lens 1 is divided to visible light and infrared light by using a dichroic mirror and the visible light is sent to a focus glass 3 and the infrared light to a mirror 4. The infrared light is then detected with a detecting element 7. In this way, the leading of the visible light into the distance measurement system is obviated and the finder becomes bright. By detecting the out-of-focus of the visible light and infrared light from the objective lens and changing the focusing position, the out-of-focus of the finder and film plane may be eliminated through the distance measurement by the infrared light.
