    摘要： A photovoltaic power conditioning system and method is provided. The system includes an isolated DC/DC converter (41), a DC/AC inverter (42), and a sine filter (43). The isolated DC/DC converter (41) receives a DC voltage from a solar cell through a parallel connection structure and converts the DC voltage into another DC voltage and then outputs the converted DC voltage through a series connection structure. The DC/AC inverter (42) converts the DC voltage output from the isolated DC/DC converter into an AC voltage. The sine filter (43) performs sine filtering on the AC voltage output from the DC/AC inverter and outputs the filtered AC voltage. The system employs a topology allowing it to be responsible for part of the output capacity, thereby significantly reducing the required capacity and increasing the system efficiency, so that the system can be applied to small and large-capacity photovoltaic power generation.

    摘要： A method for fabricating a multi-domain liquid crystal cell is disclosed, wherein first and second alignment directions are formed in first and second portions of an alignment layer provided on a substrate by selectively subjecting the first and second portions to different energy doses of linearly polarized ultraviolet light. Liquid crystal material is then injected between the one substrate and another substrate and into contact with the alignment layer, thereby obtaining a wide viewing angle in the liquid crystal device.

    摘要： An external memory control circuit for a sound field processing digital signal processor capable of obtaining continuous sound listening by shortening the time that sound is cut off upon a change of the sound field algorithm depending on the listening place (i.e., concert hall, meeting hall, church or the like). The external memory control circuit is constructed to utilize a mute function only for the time required to transfer the algorithm itself where a sound field processing circuit is realized using a DSP, thereby reducing the time that sound is cut off and thereby obtaining continuous sound listening even when the sound field algorithm is changed while listening.
