    摘要： A duplexer having dual coupled line characteristics is disclosed. With a small number of resonators and without using an external device such as a chip inductor or a chip capacitor, the signals of the receiving frequency can be improvingly damped. The diameters of the transmitting terminal dielectric filter resonators and the receiving terminal dielectric filter resonators are not same, but their diameters at an open terminal and at a short circuit terminal are made different from each other so as to differentiate a coupling amount at the short circuit terminal from that at the open terminal. Further, the transmitting terminal filter resonators and the receiving terminal dielectric filter resonator are provided in a form of grooves, and sizes of the grooves near the open terminal are made different from those of the grooves near the short circuit terminal so as to differentiate a coupling amount of the resonators at the short circuit terminal from those at the open terminal. The duplexer of the present invention is used in the transmission/receiving separate type filter of the mobile communication.

    摘要： A method and apparatus for basic input/output system (BIOS) loading includes a graphics processor performing a startup operation. The method and apparatus further includes this central processing unit (CPU) having a cache memory disposed therein. The method and apparatus provides for the graphic processor writing data to the cache memory prior to the execution of the startup operations such that the graphics processor may effectively and efficiently use the expanded memory resources of the cache memory prior to the CPU allocating and utilizing the CPU-specific resources. As such, the method and apparatus allows for improved BIOS loading by allowing for a greater degree of flexibility with an improved amount of available memory resources.

    摘要： A dielectric microwave filter includes a dielectric body, a trinity of first, second and third resonant slots, a pair of cavities for transmitting input/output signals, a pair of slits, and a trinity of first, second and third resonant holes. Each of the resonant slots (and an associated resonant hole in some embodiments) functions as a resonator having a quarter wavelength. Each of the slits modulates a coupling of electromagnetic fields among the resonant slots (and resonant holes if present). All surfaces of the dielectric microwave filter are completely covered with an electrically conducting material, except for front and top surfaces of the dielectric body. Since the resonators having a quarter wavelength may have reduced surface dimensions, the filter may accommodate associated surface input/output coupling cavities and also be more easily manufactured in a miniaturized structure. In addition, since the filter provides inductive coupling between resonators, it may better preserve a desired overall filter performance.
