摘要： A method for producing an electrochemically advantageous lithium ion-conductive solid electrolyte with high ionic conductivity, low electronic conduction and electrochemical stability is disclosed. The method comprises the steps of synthesizing lithium sulfide by reacting lithium hydroxide with a gaseous sulfur source at a temperature of not less than 130.degree. C. and not more than 445.degree. C., thermally melting plural compounds containing at least silicon sulfide and the synthesized lithium sulfide, and cooling the molten mixture. The silicon sulfide is synthesized by the steps of adding a silicon powder to molten sulfur while stirring to disperse the silicon powder in the molten sulfur and heating the silicon powder-dispersed sulfur in a reaction chamber under reduced pressure.

摘要： Silicon sulfide is manufactured from the fine powder of silicon having a particle size in the range of 60 to 100.mu., covered thoroughly with sulfur at lower temperature less than 700.degree. C. in vacuum. In order to produce the silicon sulfide, silicon should be ground in a non-oxidizing atmosphere to prevent the formation of a silicon oxide layer that remains in the product and degrades the purity of the product. The silicon powder is dispersed sufficiently in the molten sulfur. At this time, the quantity of added sulfur needs more than 1.1 times in comparison with the stoichiometric quantity of silicon sulfide. All surfaces of silicon powder should be covered with sulfur to avoid sintering between silicon particles in the whole process of the reaction.

摘要： A portable communication terminal provides multiple transceivers allowing reception and transmission of signals in accordance with multiple wireless communication systems (e.g., cdma2000 1×-EV DO and cdma2000 1× systems). When the predicted future data communication speed becomes lower than the prescribed threshold, the portable communication terminal automatically switches from one system to another. In addition, the portable communication terminal monitors amounts of data that are received by the preset time period (Td) each. That is, if the reception data rate is continuously reduced lower than the prescribed threshold for the prescribed time period (T), the portable communication terminal automatically switches from one system to another. Thus, it is possible to normally provide the user with a good data communication service, regardless of data communication environments.
摘要翻译：便携式通信终端提供允许根据多个无线通信系统（例如，cdma2000 1x-EV DO和cdma2000 1x系统）的信号的接收和传输的多个收发器。当预测的未来数据通信速度变得低于规定的阈值时，便携式通信终端自动地从一个系统切换到另一个系统。此外，便携式通信终端监视每个接收的预设时间段（Td）的数据量。也就是说，如果接收数据速率在规定的时间段（T）内持续降低到低于规定的阈值，则便携式通信终端自动地从一个系统切换到另一个系统。因此，无论数据通信环境如何，通常可以向用户提供良好的数据通信服务。
