A multilayered structure having a liquid layer on a surface of a plastic underlying layer, wherein a liquid diffusion prevention layer is provided on the lower side of the underlying layer to suppress or block a diffusion of a liquid that forms the liquid layer, and a covering ratio F of the liquid layer is maintained to be not less than 0. The string is elastic and made of transparent material, TPU. This invention also provides an artificial gene which codes for the super-compound interferon or its equivalent. The converter generates an image signal with a smaller blur than that of a signal of a blurred image output from the detector by performing a filtering process of the optical transfer function to improve a contrast. A routing method for a multilayer design layout that receives a first set of user specified preferred routing directions for particular regions of the multilayer design layout.
