A method for preparing a functionalized polymer, the method comprising the steps of: polymerizing monomer to form a reactive polymer, and reacting the reactive polymer with an imine compound containing a heterocyclic group and a hydrocarbyloxy-substituted or silyloxy-substituted aryl group. The electrodepositing solution permits an electrodeposition film of an electrodeposition material to be formed by deposition on a conductive material upon application of a voltage between the conductive material and a counter electrode. The fetching and providing steps are repeated for each allocated database. A flexible wall portion between said air channel and pocket that expands into the pocket upon pressurization of said air channel.
