    • An optical recording medium includes an integrated circuit (IC) module whose exposed surface is masked so as not to be visually recognized. The optical recording medium can be efficiently manufactured without degrading the essential function thereof. The optical recording medium includes a transparent substrate, an optical recording layer and a protective layer provided in this sequence. The IC module is buried in the optical recording medium so that one surface of the IC module is exposed on the protective layer. The optical recording medium also includes a hardened surface layer, transparent to a light beam for reproducing information recorded in the optical recording layer, or for reproducing information recorded in the optical recording layer and recording information in the optical recording layer, provided on a surface of the transparent substrate where the light beam is projected, and a masking layer provided in a region behind the IC module on the external surface of the hardened surface layer.
    • 光记录介质包括其曝光表面被掩蔽以便不被视觉识别的集成电路(IC)模块。 可以有效地制造光学记录介质,而不会降低其基本功能。 光记录介质包括透明基板,光记录层和按此顺序提供的保护层。 将IC模块埋入光记录介质中,使得IC模块的一个表面暴露在保护层上。 光学记录介质还包括硬化表面层,对于用于再现记录在光学记录层中的信息的光束是透明的,或者用于再现记录在光学记录层中的信息和记录在光学记录层中的信息, 其中投射光束的透明基板和设置在硬化表面层的外表面上的IC模块后面的区域中的掩模层。

    • A seal structure sealing a fitted part between the guide surface of a bearing part and a shaft part to prevent a fluid from flowing in a direction from a high-pressure fluid side to a low-pressure fluid side. The seal structure comprises a seal ring storage part having a radial contact surface surrounding the shaft part which is formed on the high-pressure fluid side of the bearing part and a seal ring disposed in the seal ring storage part, allowing its side surface facing the contact surface to come into contact with the contact surface, and allowing its inner peripheral surface to be fitted to the outer peripheral surface of the shaft part. The seal ring is formed in such a relative dimension that, even if elastically deformed by the pressure of the sealed fluid, the elastically deformed expanded portion thereof is not brought into contact with the peripheral surface of the seal ring storage part.
    • 密封结构,其密封轴承部件的引导面与轴部之间的嵌合部,防止流体从高压流体侧向低压流体侧流动。 该密封结构包括密封环收纳部,该密封环收纳部具有包围形成在轴承部的高压流体侧的轴部的径向接触面和设置在密封环收容部中的密封环,使其侧面朝向 接触面与接触面接触,并且允许其内周面与轴部的外周面嵌合。 密封环形成为相对尺寸,即使被密封流体的压力弹性变形,其弹性变形扩大部分也不会与密封环收纳部的周面接触。
