Disclosed is a method for operating a hybrid drive train (1) comprising an internal combustion engine (2) and an electric machine (3) as drive units as well as a parallel transmission that is provided with a first input shaft (4a), a second input shaft (4b), and an output shaft (9). The first input shaft can be coupled to the output shaft via at least one first gear while the second input shaft can be coupled to the output shaft via at least two second gears. The internal combustion engine can be effectively connected to the first input shaft via a first clutch and can be effectively connected to the second input shaft via a second clutch. The electric machine is drivingly connected to the second input shaft. Said method encompasses the following steps: a first gear is engaged; torque is applied to the first input shaft by means of the internal combustion engine via the first clutch; a second gear is engaged; torque is applied to the output shaft by means of the electric machine; the torque transmitted via the first clutch is reduced by creating clutch slip while the torque of the electric machine is increased; the torque of the electric machine is reduced to zero, and a second second gear is engaged while the torque transmitted via the first clutch is increased by reducing slip on the first clutch; torque is transmitted to the output shaft by means of the electric machine.

An optical unit with shake correcting function may include a movable module having a lens, a fixed body supporting the movable module, a shake detection sensor for detecting shake of the movable module, and at least one pair of magnetic drive mechanism for shake correction which is structured on both sides of the movable module so that the movable module is swung with respect to the fixed body on the basis of detection result of the shake detection sensor to correct the shake of the movable module. The magnetic drive mechanism for shake correction is disposed so that a shake correction magnet is held by the fixed body and a shake correction coil is held by the movable module. Further, a shake correction coil may be disposed in a first region, where magnetic lines of force generated by a shake correction magnet are directed in directions generally going away from a supporting point part and / or a second region where magnetic lines of force generated by the shake correction magnet are directed in directions generally going toward the supporting point part.

A power transmission mechanism which is capable of employing one electric motor as a drive source for driving drive wheels and as a drive source for cranking an engine, thereby making it possible to reduce manufacturing costs of the hybrid vehicle, and preventing the motor from offering an extra rotational resistance to the engine when the drive wheels are being driven by the engine, thereby making it possible to enhance fuel economy. In the power transmission mechanism for transmitting the driving force from the engine and / or the electric motor to the drive wheels, when a synchro-clutch for the electric motor, driven by a switching actuator, connects the drive shaft of the electric motor and a driving drive shaft gear to each other, the electric motor is connected to the drive wheels via a meshing gear pair (driving drive shaft gear and driving output shaft gear), whereas when the synchro-clutch connects the drive shaft of the electric motor and a cranking drive shaft gear to each other, the electric motor is connected to the engine via a meshing gear pair (cranking drive shaft gear and cranking input shaft gear), the input shaft of the transmission, and a clutch.
