A system and method for automated recovery of processing of a unit of work during an error in a batch processing system is disclosed. Infrared ray lamp of the present invention has: a curved glass tube which has a form that extends in longitudinal direction, its crossing angle of the tangent lines of both ends along that longitudinal direction being 2 degrees or more; and a single or a plurality of heating elements which are sealed in the glass tube and has a flexibility to curve around the glass tube. Acquisition of the time domain signal is done during the duration of the sweeping frequency excitation. The magnetic layers, the access lines, and the at least one keeper layer form a substantially closed flux structure. The fluorinated alcohol also imparts good stain resistance to the grafted copolymer.
