An image data outputting apparatus and method form satisfactory images regardless of characteristics of an image forming apparatus by outputting copy forgery preventing image data for preventing copy-based forgery to the image forming apparatus. The invention can enable the specification of a mark so that the mark is associated with recording data obtained at a time other than the time at which the mark is specified, i. The end effector includes a first jaw member and a second jaw member. Among other advantages, this allows a smaller, more compact design that provides higher gripping and pulling power. A system for of starting up a gas phase polymerization reactor, comprising a controller coupled to the polymerization reactor and controlling an amount of hydrocarbon absorbed in a polymer seedbed during startup to avoid formation of agglomerates or sheeting on an interior wall of the reactor.
