    Abstract: A method and device for handling the refresh requirements of a DRAM or 1-Transistor memory array such that the memory array is fully compatible with an SRAM cache under all internal and external access conditions. This includes full compatibility when sequential operations alternate between memory cells in same row and column locations within different memory banks. The device includes bi-directional buses to allow read and write operations to occur between memory banks and cache over the same bus. The refresh operations can be carried out without interference with external accesses under any conditions.

    Abstract: An umbrella table with an inlaid turntable is disclosed. The table includes a tabletop having a substantially planar top surface with a circular aperture therein. A disc is rotatably mounted in the circular aperture. The disc has a substantially planar upper surface and a central opening therethrough. The top surface of the tabletop and the upper surface of the disc are substantially coplanar, and the central opening is capable of receiving a cylindrical shaft such as the shaft of an umbrella.

    Abstract: A method of etching a sacrificial oxide layer covering an etch-stop silicon nitride underlayer, involves exposing the sacrificial oxide to anhydrous HF at a temperature of less than about 100° C. and/or at vacuum level lower than 40 Torr; and subsequently performing an in-situ vacuum evaporation of etch by-products at a temperature of more than about 100° C. and at vacuum level lower than the 40 Torr without exposure to ambient air.

    Abstract: A power system for dual-motor hybrid vehicle is a combined driving unit fed with fuel and electric power, comprising: an internal combustion engine, a motor, a clutch, a transmission, a power battery, a braking system and an entire vehicle controller, wherein the system further comprises: a main motor, an auxiliary motor, and a mechanical stepped transmission, a rotor shaft of the main motor being connected with the output shaft of the transmission, a rotor shaft of the auxiliary motor being connected with the crankshaft of the internal combustion engine; the main motor and the auxiliary motor being electrically connected with the power battery. With the control of the entire vehicle controller, the vehicle can be driven automatically by the hybrid power system in the follow modes: pure motor driving mode, series driving mode, parallel driving mode, hybrid driving mode, idling stop mode of the internal combustion engine, braking energy recovery mode, independently driving mode of the internal combustion engine, and motor auxiliarily driving mode during shifting. The present invention provides a new power system for hybrid vehicle, with simple structure, lower cost, less energy consumption and less exhaust gas emissions.
