摘要:
A computer housing includes a main housing, a mounting frame, and a first cover. The main housing defines an accommodation space adapted to receive a motherboard module and a data-reading device therein. The mounting frame is disposed removably within the main housing, and is adapted to be mounted with the data-reading device thereon. The first cover is attached openably and closably to the main housing, and is disposed in proximity to the mounting frame for covering a top end of the accommodation space in the main housing. A first notch in the main housing is aligned with a second notch in the first cover such that the first and second notches form cooperatively an opening aligned with a disk slot in the data-reading device.

The present invention relates to a dye-sensitized solar cell that exhibits improved photoabsorption efficiency and optoelectronic conversion efficiency in the long-wavelength region. The dye-sensitized solar cell of the present invention, in coordination with an outer loop, comprises: a first substrate; a second substrate; and a photoenergy conversion layer disposed between the first substrate and the second substrate. Herein, the photoenergy conversion layer comprises an electrolytic condensed matter and pluralities of dye-adsorbed units dispersed in the electrolytic condensed matter. In addition, a first photonic crystal layer is disposed on the surface of the first substrate. A beam of light from the external environment can pass through the first photonic crystal layer and the first substrate to arrive in the photoenergy conversion layer. The photoenergy conversion layer can convert the photoenergy of the light to electric energy and the outer loop electrically connects to the first substrate and the second substrate.

The invention provides a servo calibration mark detection circuit for use in an optical disk drive. In one embodiment, the servo calibration mark detection circuit comprises a summing processor, a slicing level generator, and a comparator. The summing processor sums an intensity of a light beam reflected from both an inner groove and an outer groove to obtain a first signal. The slicing level generator generates a slicing level. The comparator then compares the first signal with the slicing level to obtain a second signal, wherein the second signal indicates a first location of a first servo calibration mark recorded on the inner groove and a second location of a second servo calibration mark recorded on the outer groove.

A computer includes a main housing having a front wall formed with a slot therethrough, and a luminous device. The luminous device includes an elongated insert plate and a light source. The insert plate is made of a transparent light conducting material, and has an insert portion disposed fixedly within the slot in the main housing, and a serrated reflecting portion disposed behind the insert portion and formed with a plurality of interconnected light-reflecting surfaces. Any two adjacent reflecting surfaces form an angle therebetween. The light source is attached fixedly to the insert plate, and directs light toward the reflecting portion of the insert plate. Light emitted from the light source is diffused by the reflecting surfaces so that the insert portion of the insert plate has a uniform luminescence distribution.
