An optical beam scanning device includes a rotating polygon mirror for scanning a beam from a pre-deflection optical system in a main scanning direction and two mirrors 23, 25 for imaging the beam scanned by the rotating polygon mirror 5 on an image plane. Aspects of the systems include devices having a sealable container dimensioned to accommodate a pharmaceutical composition; and an amount of an inactivating substance, e. The bio-oil esterification reaction is catalyzed by addition of alcohol and acid catalyst. When the conditional branch code is predicted as taken in the prediction operation, a target address indicated by the target address information may be fetched at a cycle time indicated by the branch time information. The at least one hydrocarbon reservoir and the at least one hydrate reservoir can be concurrently developed.
