Abstract:
(EN) The purpose of the present invention is to reduce thermal deformation occurring in a composite member that includes a glass member and a substrate. This composite member contains a glass member, which is a forming part, and a substrate which supports the glass member. When using a specific formula in which Hm is the thickness of the glass member, Em is the Young's modulus of the glass member, αm is the linear expansion coefficient of the glass member, Hs is the thickness of the substrate, Es is the Young's modulus of the substrate and αS is the linear expansion coefficient of the substrate, the warpage ΔH of the glass member, in the case that the temperature difference ΔT = 1000°C, is less than 0.004 mm, wherein the temperature difference ΔT is the difference between room temperature and the temperature at which warpage of the glass member is 0. ΔH is defined in the specification.
(FR) Le but de la présente invention est de réduire la déformation thermique survenant dans un élément composite qui comprend un élément en verre et un substrat. Cet élément composite contient un élément en verre, qui est une partie de mise en forme, et un substrat qui maintient l'élément en verre. Lors de l'utilisation d'une formule spécifique dans laquelle Hm est l'épaisseur de l'élément en verre, Em est le module de Young de l'élément en verre, αm est le coefficient d'expansion linéaire de l'élément en verre, Hs est l'épaisseur du substrat, Es est le module de Young du substrat et αS est le coefficient d'expansion linéaire du substrat, le gauchissement ΔH de l'élément en verre, dans le cas où la différence de température ΔT = 1 000 °C, est inférieur à 0,004 mm, la différence de température ΔT est la différence entre la température de la pièce et la température à laquelle le gauchissement de l'élément en verre est de 0. ΔH est défini dans la description.
(JA) 本発明は、ガラス部材と基材とを含む複合部材に生じる熱変形を緩和することを目的とする。本発明は、成形部であるガラス部材と、前記ガラス部材を支持する基材とを含む複合部材であって、前記ガラス部材の厚さをHm、前記ガラス部材のヤング率をEm、前記ガラス部材の線膨張係数をαm、前記基材の厚さをHs、前記基材のヤング率をEs、前記基材の線膨張係数をαsで表した特定の式を使用したときに、前記ガラス部材の反りが0である温度と室温との温度差ΔT=1000℃の場合の前記ガラス部材の反りΔHが0.004mm未満である、複合部材に関する。ΔHは明細書中に定義されている。
