The present invention relates to a percutaneous absorption preparation comprising an anti-dementia drug, which is lower skin irritation. The modification is accomplished by crosslinking the three-dimensional surfaces andor by coating the three-dimensional surfaces with a layer of a predetermined material. The operating system has one or more file management tools. The NIC may respond to future network storage command by supplying the data from the solid-state disk rather than initiating a network transaction. A second electrically conductive element can be formed extending at least within the opening and electrically contacting the conductive pad and the first conductive element. Optionally the main body has a cross-section that accommodates the cross section of the rail and the rail is welded to the channel.
