Abstract: An evacuation route guidance system, which can respectively acquire one or more images shot by one or more cameras placed near roads of a target area, and a hazard map which includes locations of one or more dangerous places and locations of one or more safe areas in the target aera, including: a movement analysis part for analyzing movement of one or more moving bodies passing through a road in the target area based on one or more images shot by the one or more cameras at a time of occurrence of a disaster; a route creation part for creating a route adapted to movement of a moving body passing through the road, which route enables the moving body to move to a safe area by avoiding the one or more dangerous places; and a route output part for outputting the route to a predetermined display apparatus.

Abstract: Provided is a voltage regulator capable of suppressing a current consumption in a non-regulation state with a simple circuit configuration. The voltage regulator includes an output transistor supplying an output voltage based on a control voltage, an error amplifier circuit supplying an amplified signal obtained by amplifying a difference between a voltage based on the output voltage and a reference voltage, a common source amplifier circuit supplying the control voltage to the output transistor based on the amplified signal, and a non-regulation state detection circuit supplying a detection signal to the common source amplifier circuit. The common source amplifier circuit includes a current control circuit including a plurality of parallel paths connecting between a control terminal of the output transistor and a power supply terminal, the plurality of parallel paths including a path to be closed in the non-regulation state and a path to be opened in the non-regulation state.
