摘要:
An exposure device is provided. The exposure device includes an alignment stage unit, an exposure processing unit and a workpiece moving mechanism. The alignment stage unit includes: an alignment stage that holds a workpiece having workpiece marks thereon; at least one first alignment microscope that detects the workpiece marks of the workpiece; and a first moving mechanism that relatively moves the alignment stage and the first alignment microscope in an 1-axis direction by a width of the workpiece. The exposure processing unit includes: a mask stage that holds a mask having mask marks thereon; a second alignment microscope that detects the mask marks of the mask; and an exposure stage that holds the workpiece. The workpiece moving mechanism moves the workpiece from the alignment stage unit to the exposure processing unit.

摘要:
Electric field easing members (corona rings) for easing concentration of electric fields caused at edges of a core are disposed between the core and a winding to form a gap so to allow the presence of a cooling medium (insulating oil) between the top and bottom surfaces of the core and the electric field easing members. Thus, pressboards between the core and the electric field easing members become unnecessary, a wire-wound apparatus can be prevented from having a short service life due to the degradation of the pressboards, and the pressboards can be made to have a long service life because the electric field easing members are not heated by thermal conduction from the core.
