Abstract: Crystals of paroxetine hydrochloride ½-hydrate are allowed to separate out by adding water to a solution or suspension comprising paroxetine hydrochloride and a polar organic solvent which contains no water or at most 60% by weight of water to adjust the water content to at least 70% by weight when crystals of paroxetine hydrochloride ½-hydrate are allowed to separate out in a water-containing polar organic solvent. Crystals of paroxetine hydrochloride ½-hydrate being not colored in pink can be allowed to separate out in the presence of hydrogen chloride when crystals of paroxetine hydrochloride ½-hydrate are allowed to separate out in water or a water-containing polar organic solvent.

Abstract: In a variable stroke-characteristic engine for a vehicle, a control shaft and a control link are disposed on a front side of a vehicle body with respect to a crankshaft. An actuator for driving the control shaft is disposed on an outer surface of an engine block on the front side of the vehicle body. Thus, the actuator projects as much as possible from a position of the engine block toward the front side of the vehicle body so that traveling wind from ahead of the vehicle is effectively applied to the actuator to enhance the cooling effect. Hence, any temperature increase of the actuator is suppressed. Moreover, the actuator is disposed as far as possible from an exhaust manifold that is heated to a high temperature by the heat of an exhaust gas.
