Abstract: PURPOSE:To keep an output level constant over a wide range, by canceling the temperature fluctuation of an output level caused by the temperature fluctuation of a base-emitter voltage of an output transistor (TR) in a current switching circuit such as a binary logical circuit. CONSTITUTION:A temperature compensating circuit 31 where the temperature coefficient of a base potential of output TRs 45, 46 is negative, is connected to the base of the output TRs 45, 46, and an output level is compensated in terms of temperature over a wide range.

Abstract: PURPOSE:To detect the capacity of a battery with high accuracy, by providing an operational processing function for subjecting the open voltage of the battery detected upon opening of recharge circuit to temperature correction and calculating the capacity of the battery. CONSTITUTION:Sensors 10 to 13 function when they are set to operational conditions and information is fed through an A/D converter 14 to a main control section 6. The main control section 6 checks zero discharge current. When the discharge current is zero, a second switch 4 functions to turn a recharge circuit OFF.
