A polyarylene copolymer which comprises aromatic compound units having a main chain containing one or more electron-withdrawing groups therein and aromatic compound units having a main chain containing no electron-withdrawing groups therein, and a proton-conductive membrane comprising the polyarylene copolymer having sulfonic acid groups. At least one of a sender identifier of the image file, a subject identifier of the image file and a scan condition of the image file is stored. During the occurrence of overlapping phases between operation of switching control mean 50 for switching a shifting state and operation of engine starting and stopping control means 90 for starting or stopping the engine, execution control means 82 enables the operations to be sequentially executed so as to avoid overlapping executions, thereby suppressing the switching shocks. The assembly further includes a hanger adapted to connect to the upper end of the injection string, wherein the hanger is further adapted to land in the longitudinal bore of the mandrel. The form provides an easy method for winding as well as increased structural integrity in the final armature to enable it to transfer torque between the rotor and stationary housing. Upon receiving a door opening signal, a timer of control means starts counting and when a first period lapse judgment section judges that the count time exceeds a first period T1, a central control section instructs a heating means control section to stop the operation of heating means.
