    • The present invention relates to a strip for connecting and/or sealing a joint. Said strip comprises a first layer and a reinforcement element. Said strip having a first surface and a second surface, said first and second surfaces have a longitudinal extension and a transverse extension, said longitudinal extension having longitudinal sides, the longitudinal sides comprises edge means. Said first layer and/or edge means is made of polymeric material. Furthermore, said first layer and edge means hermetically cover the reinforcement element, and said edge means during the connecting and/or sealing of the joint provide a slope, said slope extending from the first surface downwards against a plane, said plane substantially being aligned with the second surface, so that the edge means enhances the adhesion of the strip to the joint. The invention also relates to methods for manufacturing the strip as well as to uses of said strip.

    • The invention relates to an optical disc drive that comprises rotating means, defining a rotating axis for an optical disc, and an optical scanning device, for scanning said optical disc with a light beam. These optical scanning means themselves comprise a first light source, for producing said first light beam, focusing means, provided between the first light source and a focusing point on an information layer on the disc, an optical detector, for receiving a first backward beam reflected from said information layer, and a second light source, for producing a second light beam also transmitted to said focusing means and for measuring tilt from the position, on said optical detector, of a second spot corresponding to a second backward beam obtained after reflection of the second light beam on the information layer. According to the invention, a diffractive structure, provided with diffracting elements for substantially refocusing the returning second beam onto the detector, is provided between said focusing point and said optical detector. This diffractive structure, consisting of a series of ring-shaped prisms, is attached either to one surface of a servo-lens positioned just before said optical detector, or to one surface of an objective lens used as focusing means, or to a separate plate. The diffractive structure may also be approximated by a step-wise structure.
    • 本发明涉及一种光盘驱动器,其包括限定光盘的旋转轴的旋转装置和用于以光束扫描所述光盘的光学扫描装置。 这些光学扫描装置本身包括用于产生所述第一光束的第一光源,设置在第一光源和盘上的信息层上的聚焦点之间的聚焦装置,用于接收反射的第一反向光束的光学检测器 以及第二光源,用于产生也被传送到所述聚焦装置的第二光束,并用于测量在所述光学检测器上的所述位置的倾斜,所述第二光斑对应于在反射后获得的第二反射光束 信息层上的第二个光束。 根据本发明,在所述聚焦点和所述光学检测器之间设置有用于将返回的第二光束基本上重新聚焦到检测器上的衍射元件的衍射结构。 这种由一系列环形棱镜组成的衍射结构被附着到位于刚好在所述光学检测器之前的伺服镜头的一个表面上,或者附着到用作聚焦装置的物镜的一个表面上,或者连接到单独的板 。 衍射结构也可以通过逐步结构近似。
