    • An optical component for an optical pick-up for converging a laser beam having a particular wavelength onto a recording layer of an optical disc. The optical component comprises a base material formed of a resin composition, an undercoating which is formed of three layers of thin films having a same main constituent and is formed on a top surface of the base material, and a functional thin film formed on a top surface of the undercoating. In this configuration, each of a first layer and a third layer of the undercoating is a thin film formed without introducing oxygen, and a second layer is a thin film formed while introducing oxygen. A film thickness of the undercoating falls within a range of 160 nm to 270 nm, and film thicknesses of the thin films constituting the undercoating are substantially equal to each other.
    • 一种用于将具有特定波长的激光束会聚在光盘的记录层上的用于光学拾取器的光学部件。 光学部件包括由树脂组合物形成的基材,底涂层,其由具有相同主要成分的三层薄膜形成,并形成在基材的顶表面上,以及形成在顶部的功能性薄膜 表面的底漆。 在该结构中,底涂层的第一层和第三层中的每一层都是不引入氧而形成的薄膜,第二层是在引入氧的同时形成的薄膜。 底涂层的膜厚在160nm〜270nm的范围内,构成底涂层的薄膜的膜厚基本相等。

    • A component in a horizontal direction (the x-axis component) of a movement amount first acquired after a pointing device is reset and a component in a vertical direction (the y-axis component) are compared, a movement input is regarded as provided only in the horizontal direction in case the absolute value of the x-axis component is larger than the absolute value of the y-axis component, a movement input is regarded as provided only in the vertical direction in case the absolute value of the y-axis component is larger than the absolute value of the x-axis component, a movement input is regarded as provided in the same direction unless the ratio of components of movement inputs is greatly changed subsequently, and continuous movement inputs in the same direction are facilitated.
    • 比较指示装置复位后首先获取的移动量的水平方向(x轴分量)和垂直方向上的分量(y轴分量)的分量,仅将运动输入视为仅提供 在x轴分量的绝对值大于y轴分量的绝对值的情况下,在水平方向上,仅在垂直方向上设置移动输入,在y轴的绝对值 分量大于x轴分量的绝对值时,移动输入被认为是沿相同的方向提供,除非随后的运动输入的分量的比例大大地改变,并且便于相同方向的连续运动输入。
