The invention provides rubber composition usable for the manufacture of tires, comprising at least one diene elastomer, one white filler as reinforcing filler and one coupling agent, the white filler comprising a titanium oxide having the following characteristics: it comprises more than 0. A semiconductor device includes a dielectric film over a dielectric layer. The outer sleeve has an open proximal end and an open distal end. The flange attaches to the subject’s head, firmly holding the ear coupler in place over the ear. The assembly and method achieve a highly uniform thickness and composition of deposition material or uniform etching or polishing on the semiconductor substrates by retaining the semiconductor substrates on a moving cathode immersed in an appropriate reaction solution wherein a wire mesh anode rotates about the moving cathode during electrochemical reaction. Specifically, the positional relationship between the image pickup element and the lens is fixed by adhesion of organic solvent or the like.
