A lens element has an annular flange portion which has a tapered lateral surface so as to form at least an annular clearance tapering from a rear edge thereof when it is received in a lens holder. The lubricant composition may comprise at least on carrier. When the mounter mounts the cartridge with the spacer at the spaced position, the abuter abuts the spacer retracting it from the spaced position after insertion so that the function member taking the first position abuts the receiver. After removing the second resist film, the lower layer film is etched by using the second intermediate layer pattern as a mask, so as to form a lower layer pattern. The shift estimation method may provide a shift value corresponding to the shifted template vector which generates the stored vector p as an estimate for the shift between the received signal and the template signal f. The overlapping portion of the second panel is fastened to the tab of the first panel to form a continuous shear diaphragm for the floor or roof.
