    摘要: An objective lens actuating apparatus is provided for an optical read/write head. The apparatus includes a base; a lens holder floating over the base; an objective lens, fixed on the lens holder; two multi-polar magnets mounted on the base; and two coil plates located between the two magnets and fixed on the lens holder. Each coil plate has a tracking coil, a focusing coil, and a tilting coil, which overlaps different magnetic poles of each magnet. The coils generate Lorentz Forces after currents being input into the coils, so as to drive the lens holder moving or tilting.

    摘要: A magneto-resistance transistor including a magneto-resistant element which may function as an emitter and a passive element which may function as a collector. The base may be interposed between the passive element and the magneto-resistant element, thereby coupling the passive element with the magneto-resistant element. A magnetic field of a given strength may be applied to at least a portion of the magneto-resistant transistor, the given strength determining a resistance in the at least a portion of the magneto-resistant transistor. Thus, by adjusting the given strength of the magnetic field, the resistance may be adjusted. Therefore, different emitter current inputs may be achieved with a fixed voltage. Further, a base current may vary with a controlled variation of the emitter current input.

    摘要: A fluorescence inspection spectrometer uses a stimulated light beam emitted by a light source, passes through the first collimator, the polarization beam splitter, and the objective lens, and then focuses on a test object to detect the excited fluorescence. Through the first optical filter module, the second collimator, and the reception of the photo detector, the fluorescence is converted into an output signal for fluorescence signal analysis. The feature is that the objective lens is installed on an actuator. More accurate data can be measured by fine-tuning the actuator so that the objective lens reaches its optimal focal position.

    摘要: A method provides efficient data transmission between an input-output card with an add-on memory card and a host system. The input-output card carrying an inserted memory card is connected with the host system to improve the mechanical strength of the arrangement. An input-output controller on the input-output card controls a switch that switches between data buses. The memory card and the input-output card optionally share all data buses of the input-output card to transmit data with the host system, directly transmit data between each other, or respectively use a portion of them to achieve a better transmitting efficiency.

    摘要: The present invention is an optical pick-up head with a single objective lens, which discloses an optical pick-up head that can retrieve data from CD and DVD with different thickness using a single objective lens and a special optical element on the optical path of the optical pick-up head. This optical element is a three-beam grating which is formed a reflective film thereon, for example, by coating a metal or dielectric layer to achieve the goal of controlling the numerical aperture. Thus, this invention provides a single objective lens optical pick-up head with simple structure, low cost, easy assembling, and applications to multi-wavelength systems.
