A method is employed for operating a wind turbine. In a case where the auxiliary storage device is determined to be an SSD based on type information that is acquired when the image forming apparatus is activated, a predicted retention period is calculated, and is set in a part of the apparatus that operates in the power save state. Alternatively, or in addition, in a transform-based low-bit-rate audio coding system, a transient in the audio signal stream is detected and a portion of the distortion artifacts are time compressed such that the time duration of the distortion artifacts is reduced. An optical termination field includes fiber optic adapters carried by the swing frame chassis. The wetting solution suitable for use in the process of the present invention includes water, an organic solvent, an acidic and basic solution. The sheet body has a repair wire attached to a part thereof for repairing an electrode of the flat display panel.
