    • PROBLEM TO BE SOLVED: To provide a forming mold having a coating layer formed of a diamond-like carbon film (to be called DLC film, thereafter), and hardly causing roughening of the mold base material due to etching when removing the DLC film, or removing the DLC film in a regenerating process. SOLUTION: The forming mold having the coating layer formed of the DLC film, is characterised by having an intermediate layer as described in the following, between the coating layer and the forming mold base material; the intermediate layer is formed of (Cr 1-a Si a )(B x C y N 1-x-y ) and is a film layer satisfying the following formulae (1)-(3) and formed under a gas pressure of 0.2-0.5 Pa. In the formulae, 0.5≤a≤0.95 formula (1), 0≤x≤0.2 formula (2) and 0≤y≤0.5 formula (3), provided that in the formulae (1)-(3), a shows atomic ratio of Si, x shows atomic ratio of B and y shows atomic ratio of C.

    • PROBLEM TO BE SOLVED: To provide a method of manufacturing a high performance lens while stably continuing press-molding without re-machining a molding die. SOLUTION: The method of manufacturing the shaped article includes pressing a molding base material softened by heating with a pair of dies having a molding surface machined into a prescribed shape. The press speed of at least either one of the dies is corrected based on the measured optical performance of the formed molding and the shaped article is formed by the corrected speed. The optical performance of the shaped article is maintained by correcting the press speed of at least either one of the dies every time after a prescribed number of the shaped articles are formed. The press speed of at least either one of the dies is corrected and the shaped article is further formed by the corrected press speed. A molding apparatus used for the manufacturing method is provided. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供一种制造高性能透镜的方法,同时稳定地连续加压成型而不对成型模进行再加工。 解决方案:成型制品的制造方法包括用成型表面加工成规定形状的一对模具对通过加热而软化的成型基材进行加压。 基于所测量的成型模具的光学性能来校正至少任一个模具的冲压速度,并且通过校正的速度形成成形制品。 成型制品的光学性能通过在形成规定数量的成形制品之后每次更换至少一个模具的冲压速度来保持。 校正至少任一个模具的冲压速度,并且通过校正的冲压速度进一步形成成形制品。 提供了一种用于制造方法的成型装置。 版权所有(C)2005,JPO&NCIPI
