    Abstract: Provided are a delay locked loop (DLL) and a method for generating a divided clock therein. In the DLL, a width of a reference frequency for phase comparison can be changed depending on a magnitude of an operating frequency. In the DLL, a clock buffer receives a clock equal to an external clock and generates an internal clock. An enable clock generator generates a 1-period enable clock or a 2-period enable clock using a command signal generated for performing a predefined operation. The command signal is generated according to an address command signal inputted from an exterior. A clock divider divides the internal clock to generate a divided clock. The divided clock is controlled by the 1-period enable clock or the 2-period enable clock, such that the divided clock is made to be a 1-period based dividing clock or a 2-period based dividing clock.

    Abstract: Disclosed is an optical pickup apparatus. Particularly, a photo detector for use in the optical pickup apparatus detects a beam reflected from the disc, and includes a substrate for transmitting three beams (one main beam and two sub beams) reflected from the optical disc; a liquid crystal for refracting the two sub beams, that are transmitted through the substrate, at different refractive indexes according to the wavelength of a laser beam outputted from the laser diode; an electrode material for supplying power to the liquid crystal; a switch for adjusting the magnitude of an applied voltage to the electrode material; and a photodiode on which the main beam and the refracted sub beams while transmitting the substrate and the liquid crystal are projected, and transformed into electric signals. The photo detector enables to change the light-receiving magnification by installing the substrate and the crystal layer(s) in front of the photodiode, and adjusting the magnitude of an applied voltage to the liquid crystal. By refracting the beams refracted from the disc at a proper refractive index, the ±1st-order beams can be projected onto the same position, irrespective of the wavelengths. As such, the optical pickup apparatus of the present invention is capable of recording and/or reproducing information onto and/or from discs having diverse specifications.

    Abstract: There is disclosed an AC PDP comprising two plates. These two plates are opposite to each other with a plurality of parallel electrodes on one plate being across a plurality of parallel electrodes on the other. The space therebetween, sealed by a side wall, is filled with a discharge gas. A fluorescent layer is formed on the side of one of the plates in the sealed space. Opposite to the fluorescent layer, a dielectric multilayer structure is laminated on the electrodes and covered with an overcoat layer, wherein its sub-layers are of lower fluidity as they are nearer to the overcoat layer. This is accomplished by arranging the sub-layers in such a way that they may be higher in softening temperature as they are nearer to the overcoat layer. Since the sub-layers are made of glass materials, this softening temperature gradient is determined by the content of PbO and/or B.sub.2 O.sub.3 in each of the sub-layers, ranging from approximately 20-50% by weight and approximately 0.5-12.5% by weight, respectively, based on the total weight of each layer. This multilayer structure effectively prevents cracks from occurring in the overcoat layer upon sintering. Therefore, the problems of the electrode damage and the discharge gas pollution, both attributable to the cracks, can be effectively solved, and a high quality and endurable AC PDP can be provided.
