A chemically amplified negative photoresist composition is used for the formation of thick films having a thickness of 20 to 150 \u03bcm and includes an alkali-soluble resin, a compound which generates an acid upon irradiation with active light or radiant ray, and a compound which serves as a crosslinking agent in the presence of an acid. In accordance with this method of the present invention, a direct-reading material and a related material including text, sound, and images are printed on a page in a newspaper. The drive is designed such that the cover is extended and retracted in a uniform fashion. The tension spring is wound at least one turn forming a central coil and two extensions, and each of the molded portions is formed with a hinge area. Here, the transmission lines 42, 44 are longer than 45% of \u039b4 but shorter than \u039b4, when \u039b designates a propagation wavelength under an operating frequency.
