摘要： A window member (11) having an intentionally designed distribution of refractive index is used, as a transparent window member in a light transmission area of a polishing pad for detecting the end point of polishing by a CMP method. This window member (11) has areas (11a) having a high refractive index and areas (11b) having a low refractive index in its window face. In a cross section normal to the window face, the high-refractive index areas (11a) and the low-refractive index areas (11b) are alternately arranged in stripes. These areas (11a and 11b) in the window face are in a Fresnel zone plate arrangement in which the first area (center circle) is a bright one (area having a high refractive index). A plurality of such Fresnel zone plates (F) are arrayed in a matrix in the window face of the window member (11).

摘要： The present invention provides a biaxially oriented film of a polylactic acid resin that is suitable for films for bags and packaging films for various windows, particularly films for outlook window envelopes. The film is biodegradable and, as films for outlook window envelopes, is superior in the coating adaptability for an antistatic agent, a lubricant and an antiblocking agent or the like and in the high-speed cutting property. The present invention discloses a biaxially oriented film of a polylactic acid resin comprising not less than 50% by weight of a polylactic acid resin, which has a storage modulus E′at 80° C. within the range from 10 MPa to 3,000 MPa, as determined by the test method for temperature dependency of dynamic viscoelasticity, in accordance with JIS K7198 (method A); a heat shrinkage of not higher than 10%, upon heating at 80° C. for 10 seconds; and a tear strength in the width direction (TD direction) of the film of 10 to 200 mN, as determined in accordance with JIS K7128 (method B).
