Title: Power supply circuit
Inventor: HARA KOUICHI
IPC: H02J1/00
Filed: 1977-11-16
Abstract: PURPOSE: To protect a car battery when a power switch fails to turn off by switching off an engine key switch and a transistor while the power switch is being kept ON.  
     CONSTITUTION: When an engine switch 22 turns off while a power switch 26 is turning on, diodes D 6  and D 7  enter the emitter of a transistor Tr1 in series and the emitter potential rises by VD. The ON condition of the transistor Tr1, i.e. VB> VBE is not satisfied and the transistor Tr1 turns OFF. This permits a car battery to be protected when the power switch 26 fails to turn off.

Abstract: PURPOSE:To obtain a compact and lightweight optical tracking device by setting a plane reflector onto a double axis stable stage via an azimuth/high-low angle drive mechanism part and at the same time correcting the image formation to a detecting element by means of a Pechen prism. CONSTITUTION:When a plane reflector 10 catches a target, this target is picked up by a detecting element 20 of an infrared camera 18 via a beam prism 13 and a Pechen prism 17. If the center of the target image has a shift, the 1st control part 21 detects the errors in the azimuth and high-low angle directions. Then the azimuth and high-low angle directions of the reflector 10 are controlled. While the prism 17 is driven by 1/2theta to an axis (x) in the direction opposite to the rotation of the reflector 10 if this reflector 10 catches the target with a 1/2theta rotation given to the axis (x). Thus the image picked up by the element 20 is corrected to a normal state corresponding to a standard line. As a result, the camera 18 can be fixed.
