Abstract: A touch panel optical waveguide production method that ensures improved productivity while suppressing occurrence of voids. For formation of an over-cladding layer, a coating layer (4a) of an uncured or half-cured photopolymerizable resin composition as an over-cladding layer material is formed over a surface of an under-cladding layer (2) formed with cores (3). In turn, a molding die (6) composed of a light-transmissive material is pressed against the coating layer (4a) with a predetermined die surface of the molding die (6) being properly positioned with respect to the coating layer (4a), and then the coating layer (4a) is exposed to light through the molding die (6). After the exposure, the molding die is removed. Thus, the over-cladding layer is formed, in which the cores (3) are buried.

Abstract: A method of making an elastic component for incorporation into a diaper. The elastic diaper component begins as an elastic laminate (e.g., an elastic layer and a fabric layer) having a recoverable extension of at least 20% when an extension force E1 is applied. The method comprises the step of integratively pre-stretching the elastic laminate so that the elastic laminate will stretch to the same recoverable extension when a reduced extension force E2 is applied. In this manner, when the elastic laminate is used in the elastic diaper component, a lesser fitting force Ffit is required to extend the elastic component to a desired length during an initial fitting of a diaper on a wearer.
