摘要： A multilevel phase change memory element and operating method and electrodes, which are configured in a parallel structure to form a memory cell. A voltage-drive mode is employed to control and drive the memory element such that multilevel memory states may be achieved by imposing different voltage levels. The provided multilevel phase-change memory element has more bits and higher capacity than that of a memory element with a single phase-change layer.

摘要： A coaxial master-slave lens system is provided. The coaxial master-slave lens system can be either fixed-focus type or zoom type, and can be equipped to any camera equipment. In such a coaxial master-slave lens system, a slave lens is provided as an additional attachment to the master lens. The slave lens is provided with a center hollowed portion for accommodating the master lens in such a manner that the slave optical axis is in coincidence with the master optical axis; the slave front lens plane is in coincidence with the master front lens plane; the slave rear lens plane is in coincidence with the master rear lens plane; the slave front focus point is in coincidence with the master front focus point; and the slave rear focus point is in coincidence with the master rear focus point.
