A solid electrolytic capacitor comprising a foil coated with a dielectric oxide film, wherein the coated foil has slit or cut edges, and the slit or cut edges have been reformed by anodizing the foil in an aqueous oxalic acid electrolyte, then forming the foil in an aqueous citrate electrolyte, then depolarizing the foil, and then forming the foil in an aqueous phosphate electrolyte. After a sheet has stopped at a stop position immediately before the registration roller pair, the registration roller pair having been set to the separated state is set to the press-contact state. This invention also provides compositions comprising a compound of this invention and a carrier and the use of disclosed compounds and compositions in methods of treating diseases and conditions that are beneficially treated by administering apremilast. Using the digital pen, annotations and edits may be made to the hardcopy representation. The filter frame outer face has a flexible perimeter flange projecting outwardly from an uppermost portion of the filter frame outer face. The cover is then positioned over the base, by bending the flexible hinge, and latched to the base.
