    摘要： There is provided a method for fabricating a ferroelectric capacitor which comprises the steps of: forming a bottom electrode over a substrate on which a predetermined lower structure is formed; forming a thin film of polycrystalline strontium bismuth tantalate (SBT) over the entire structure; forming an amorphous thin film of SBT on the polycrystalline film of SBT; and forming an upper electrode on the amorphous film of SBT. Though the amorphous thin film of SBT is lower in dielectric constant than the polycrystalline thin film of SBT so as not to have the properties of ferroelectric, it does not have crystalline grain boundary and, thus, does not form the path for transferring material. Therefore, the amorphous thin film of SBT can block the path of leakage current. It also results in complement of bismuth lost in the processes of deposition and thermal treatment for crystallization of the ferroelectric film of SBT at a high temperature.

    摘要翻译： 提供一种用于制造铁电电容器的方法，其包括以下步骤：在其上形成有预定的下部结构的基板上形成底部电极; 在整个结构上形成多晶锶钽酸铋薄膜（SBT）; 在SBT的多晶膜上形成SBT的无定形薄膜; 并在SBT的非晶膜上形成上电极。 虽然SBT的非晶薄膜的介电常数比SBT的多晶薄膜低，但不具有铁电性质，但不具有晶界，因此不会形成转印材料的路径。 因此，SBT的非晶薄膜可以阻挡漏电流的路径。 这也导致在高温下SBT的铁电体膜的沉积和热处理过程中失去的铋的补充。

    摘要： The present invention relates to an IP based or network based audio packet switching system, and more specifically to an audio packet switching system for integrating each independent module into a single interface for consistent control and data flow. Independent modules, such as a RTP/RTCP, encoder/decoder and mixer, are interworked with reception and transmission buffers to make a system more flexible. Additionally, audio data paths inside the switch are controlled through an audio packet router. The multi protocol system employing the RTP provides a single RTP control interface for transmitting and receiving audio packets to completely manage the system totally and raises a degree of resource utilization of the system by making it easy to implement additional functions to the RTP and coder through the buffers.

    摘要： A gas insulating switchgear comprising: a first switching unit for connecting or breaking an electric circuit between a power source and a load; a second switching unit being mechanically and electrically connected with the first switching unit and being selectively movable to an electrically conducting position, an electrically breaking position or an electrically grounding position; and an actuator being connected to supply a driving force to the second switching unit so that the second switching unit can be moved. In case that the gas insulating switch gear is applied to a switchgear having a rated insulating breakage voltage level of 125 KV, the switch gear can have a rated breakage insulating voltage of more than 125 KV (150 KV) by using the vacuum interrupter and the second switching unit each having the rated insulating voltage level of about 75 KV. In addition, by adding the earthing function using the ground terminal, a worker can do a job such as a power source or load cable installation, cable maintenance and repairing in a more safe circumstance.
