A vehicle drive device includes a generator to output AC power, a converter that converts the AC power into DC power, and an inverter that converts the DC power into AC power. An electric motor is driven by the AC power output by the inverter, and an inverter controller (i) calculates a control command value in accordance with an operation command and (ii) controls the inverter based on the calculated value. A value obtained by dividing (i) an amount of the change in the control command value in a case of an increase of the operation command by (ii) a period from when the operation command changes to when the control command value reaches the control command value corresponding to post-change operation command has a negative correlation with the rotational speed of the electric motor at the time when the operation command changes.

A variable gauge train control device comprises an inverter, a location detector, and a torque calculator. The inverter collectively controls torques of main electric motors. The location detector detects an entry into a gauge changeover section. The torque calculator, upon detection by the location detector of the entry into the gauge changeover section, suspends idling control that otherwise restricts the torques of the main electric motors and calculates a first torque pattern for making the inverter operate in accordance with the torques of the main electric motors.

The focus control apparatus performs focus control of the interchangeable lens by using information obtained through detection of a focus state of an interchangeable lens and a correction value corresponding to the interchangeable lens. The interchangeable lens is a first interchangeable lens holding unique correction value calculation data used to calculate the correction value, or a second interchangeable lens not holding the correction value calculation data.
