An airgun may include a body and a nozzle. The process of the invention allows trans-dibenzoxenopyrrole compounds to be produced by a simpler procedure than conventional processes. In addition, the output of the second input clock signal CLKIN_B is resumed based on an output signal of a fourth flip-flop group which takes in an output signal from the first flip-flop group according to the second input clock signal CLKIN_B. A stator is disposed about the rotor shaft at a position to coaxially face the rotor. Metadata is stored in cache to describe content elements of a transaction, a data retrieval device determines, based on the metadata, whether cache contains a complete copy of a transaction associated with a requested content element, and the data retrieval device returns the requested content element from cache if the complete copy of the associated transaction is in cache. The apparatus includes mechanism for driving the strap in a loop around the bundle, a gripper for gripping an end of the strap, mechanism for drawing the strap taut about the bundle, and heated press elements for clamping adjacent overlapping portions of the strap together to reactivate adhesive in the strap to bond the overlapping sections together.
