    • An aberration detection device which can detect a spherical aberration sensitively by separating a light beam appropriately so as to enlarge a difference in the positions where the respective separated light beams have the minimum spot diameters, and thus to enlarge a deviation amount of the focus positions of the separated light beams, is provided. A hologram for separating a light beam reflected from an optical disk and passing through a dual element objective lens into a first light beam and a second light beam, and a detection device for receiving the first and the second light beams and detecting the deviation of focus positions of the first and the second light beams, are equipped. The light beam directed to the hologram is separated into the first light beam and the second light beam, by a first region and a second region of the hologram which are obtained by being separated at a boundary drawn at an extreme value of a curve representing a wave front when the light beam has a minimum beam diameter on an information recording layer of the optical disk.
    • 一种像差检测装置,其能够通过适当地分离光束来敏感地检测球面像差,以扩大各分离光束具有最小光斑直径的位置的差异,从而扩大焦点位置的偏移量 提供分离的光束。 一种用于将从光盘反射并通过双元件物镜的光束分离为第一光束和第二光束的全息图,以及用于接收第一和第二光束并检测聚焦偏差的检测装置 配备第一和第二光束的位置。 被引导到全息图的光束被分离成第一光束和第二光束,由第一区域和全息图的第二区域分离,所述第一区域和第二区域通过在表示a的曲线的极值绘制的边界处被分离 当光束在光盘的信息记录层上具有最小光束直径时,该光束前方。

    • A joint drive mechanism includes a plurality of link members linked via a joint portion. A drive portion is associated with the joint portion for driving the joint portion such that the link members attached thereto can be moved relative to one another in a controlled fashion. The drive portion includes a plurality of drive elements that each are capable of expanding or contracting in response to an applied electric signal so as to provide different drive outputs to the joint portion. In one embodiment, a joint portion connects link members simulating portions of a human finger. The drive portion includes a pair of drive elements connected to the joint portion by a transmission member. Each of the drive elements is expanded or contracted equally and oppositely relative to the other drive element in response to controlled applied electrical signals.
    • 联合驱动机构包括通过接头部分连接的多个连杆部件。 驱动部分与用于驱动关节部分的关节部分相关联,使得附接到其上的连杆构件可以以受控的方式相对于彼此移动。 驱动部分包括多个驱动元件,每个驱动元件能够响应于所施加的电信号而扩展或收缩,以便向接头部分提供不同的驱动输出。 在一个实施例中,关节部分连接模拟人类手指的部分的连接部件。 驱动部分包括通过传动部件连接到接头部分的一对驱动元件。 每个驱动元件响应于受控的施加的电信号而相对于另一个驱动元件相等地相对地扩展或收缩。
