Abstract: An optical disk clamping device. The device includes a diamagnetic member, a turntable, a magnet, and a clamping member. The turntable supports an optical disk. The magnet is disposed between the diamagnetic member and the turntable. The clamping member is disposed on the turntable to support the magnet. A repellent force is generated between the diamagnetic member and the magnet when the turntable rotates, pushing the magnet toward the clamping member to fix the optical disk.

Abstract: A method for phase matching matches a relative phase of a first element and a second element by detecting a magnetic flux. The method provides a magnetic flux generator to generate the magnetic flux. The method also provides a magnetic sensor in order to detect the magnetic flux. According to the magnetic flux detected by the magnetic sensor, the relative position of the first element and the second element is adjusted until the magnetic flux reaches a predetermined value, which means that the phase of the first element and that of the second element are matched.

Abstract: The present invention discloses a method for adjusting a tilt angle of an optical disc driver. The method includes the following steps. First, to move the optical pick up to close the outer end of the first and second guiding shafts. Next, the turntable drives a disc to rotate. Then, the light source provides a light to penetrate through the disc and the lens. The image sensor receives the reflection light from the disc and the lens. The monitor displays the traces projected from the reflection lights. According to the traces, the driving device adjusts the positions of the first and second guiding shafts.

Abstract: A three-dimensional laser beam detection device. The three-dimensional laser beam detection device has a portion fixed to a laser source such as an optical head, an adjusting device provided on the fixed portion, and a laser beam detection portion coupled to the adjusting device. The adjusting device has a first table movably coupled to the fixed portion in a first direction, and a first adjusting portion coupled to the first table for moving the first table relatively to the fixed portion in the first direction. The first adjusting portion is formed within the adjusting device. The laser beam detection portion has a detector to detect the laser beam radiating from the laser source. The fixed portion has a fixed relative position to the laser source, and the detector is adjustable in relation to the laser source by performing adjustment with the adjusting device.

Abstract: A concentric alignment assembly device for assembly of a first component and a second component. The concentric alignment assembly device includes a first base and a second base for receiving the first component and the second component. The first base has a pedestal and an adjusting portion, in which the adjusting portion is movably and rotatably coupled to the pedestal, and has a first platform for receiving the first component. The second base is provided on a side of the first base, and is movable within a fixed range and direction in relation to the first platform. When the second base moves toward the first base, the adjusting portion adjusts radial displacement and axial deviation of the first component in order to assemble the first component and the second component.
