In a plasma display device, a lighting rate is calculated from a video signal input in a plasma display device, and an output current of DC-DC converter (140), which is the same as a discharge current in a sustain period corresponding to the lighting rate, is synchronized with a generation timing of discharge current. With such a configuration, even if discharge current in the sustain period of each subfield is rapidly changed, a sustain pulse voltage can be kept constant.

The feed mechanism has a lead screw 11, a pickup assembly 12, an engagement piece 13, and a restrictor piece 14, a compressed coil spring 15, and a bearing portion 16. The engagement piece 13 has a thread portion 41 engaged with a screw groove 23 of the lead screw 11. The engagement piece 13 moves along the lead screw 11 and can come close to and off from the lead screw 11. The pickup assembly 12 moves together with the engagement piece 13. The restrictor piece 14 prevents the engagement piece 13 from disengaging from the lead screw 11, except when the screw groove 23 moves apart from the thread portion 41. The compressed coil spring 15 urges the engagement piece 13 toward the lead screw 11. The bearing portion 16 rotatively supports the lead screw 11 and allows the lead screw 11 to move apart from the engagement piece 13 when the engagement piece 13 has reached an end thereof.

In a hybrid vehicle of the present invention, a clutch motor, an assist motor, and an engine are connected via a dual clutch, which includes an inner clutch arranged between an inner shaft and a middle shaft and an outer clutch arranged between the middle shaft and an outer shaft. An inner rotor of the clutch motor and the engine are linked with the inner shaft. The assist motor is linked with the middle shaft. An outer rotor of the clutch motor and an axle are linked with the outer shaft. Changing the coupling state of the middle shaft changes over the connection of the assist motor between the engine and the clutch motor. The connection of the assist motor with the clutch motor in the state of underdrive or in the case of a requirement of abrupt acceleration desirably improves the driving efficiency and ensures the smooth acceleration. Regulation of gradually enhancing the coupling force of the outer clutch in the course of the changeover of the connection of the assist motor enables the rotations of the engine and the outer rotor to be synchronized quickly, thus shortening the time required for completion of the changeover.
