A fuel cap of an internal combustion device includes a fuel cap body, a restraining element, a resilient element, and a positioning element. The apparatus further includes a planar plasmon antenna that is disposed between the tip portion of the magnetic write pole and the optical component. A method of preparing a substrate coated with the aqueous coating composition and an article containing the coated substrate are also provided. The shape and texture are projected into a bilinear illumination model to generate illumination bases for the face in the image. The spring force due to deformation provides an opening bias to the suction valve such that it opens earlier in the suction stroke and offsets the effects of adhesion due to the presence of oil between the seating surface and the valve.
