The present invention aims to provide a vinyl resin which, with a polyurethane resin, is capable of providing a film excellent in mechanical strength, weather resistance, solvent resistance, and water resistance. The method includes forming an electrically conductive bottom electrode within a substrate. The deflector defines at least one pair of generally opposed reentrant slots extending from the first surface through the deflector, the reentrant slots extending from slot openings at an outer peripheral edge of the deflector inwardly from the peripheral edge toward a deflector axis. It is determined that the database associates the keyword with a first and a second place.
