Provided are a method, system, and article of manufacture for converting backup copies of objects created using a first backup program to backup copies created using a second backup program. The double actuator for moving the board in two directions is disposed at only one side of the board, so that the camera lens assembly including the optical image stabilizer can be downsized. In the method, the reaction mixture is heated at crystallization conditions and in the absence of an added external liquid phase, so that excess liquid need not be removed from the crystallized product prior to drying the crystals. Further, as the valve-closing timing of the exhaust valve 9, one of the detected actual valve-closing timing and the set target valve-closing timing is used.
