The invention is a customizable hot list used in connection with drop-down list boxes on web-based forms. The aim of the invention is to create a hub bore shape that is improved compared to prior art in order to significantly reduce mechanical stress in the piston and thus extend the service life of the piston. A fitting member is fitted to the mechanical code pattern. In other embodiments, isotropic internal stress is generated through randomized deposition or directed deposition techniques. The envelope flap also is folded so as to provide verification information from the voter while maintaining the contents of the envelope secret. The transmissivity adjustment layer 3 has a thickness of 90 angstroms or less.
