An inspection assistance device includes a damage drawing input part configured to input a damage drawing, i.e. a drawing illustrating damages of target parts, a display configured to display the damage drawing and target figures illustrating target parts to be overlaid with each other, and a storage configured to store the damage drawing separately from the target figures in connection with the target figures.

Inspection assistance device, inspection assistance method, and program

Provided is a regenerative switched reluctance motor driving system which allows a motor to have a reduced size and weight and an increased efficiency as well as improved energy recovery efficiency at the time of regenerative braking without using a neodymium magnet. Based on an angular position of a rotor in the motor, a constant current flip-flop circuitrenders two current paths alternately conductive so as to allow a rectangular-wave current having a width of an electrical angle of 180&#xb0; to alternately flow in two coils in the motor, and shifts the timing of rendering the two current paths alternately conductive, between when driving and when braking the motor, by a time during which the rotor is rotated by an angle corresponding to an electrical angle of 180&#xb0;. When driving the motor, a DC constant current power supply unitdischarges a DC power supply, while when braking the motor, it receives an input current through a negative terminal of the DC power supply, and outputs a DC current to the constant current flip-flop circuit, and further outputs a DC current regenerated from the motorthrough the constant current flip-flop circuitto a positive terminal of, and thereby charges, the DC power supply.
