  • Patent number: 10573474
    Abstract: An intelligent integrated medium-voltage alternating current (AC) vacuum switchgear based on a flexible switching-closing technology comprises a controller (24), and a vacuum switching tube (1), an insulator (9), and an switching-closing mechanism connecting piece (15), which are connected in sequence. A microprocessor is built in an intelligent circuit (23); a travel sensor is fixed to a movable contact connecting rod (5), and directly detects a motion state of a movable contact (4) and acquires accurate motion parameters of the movable contact (4); switching-closing operating parameters are obtained by comprehensively calculating arc light intensity detected by an arc light transmitter (20) and a temperature measured by an infrared temperature measuring transmitter (22), such that the switching-closing performance of switching on and switching off a medium-voltage power grid is greatly improved, switching-closing time points are accurately controlled, and “flexible” switching-closing is achieved.

  • Patent number: 9471500
    Abstract: Systems and methods for generating and storing a data structure for maintaining cache supporting compression and cache-wide deduplication, including generating data structures with fixed size memory regions configured to hold multiple signatures as keys, wherein the number of the fixed size memory regions is bounded. A first mapping is generated from short-length signatures to a storage location and a quantized length measure on a cache storage device; and unused contiguous regions on the cache device are allocated. Metadata and cache page content is retrieved using a single input/output operation; a correctness of a full value of hash functions of uncompressed cache page content is validated; a second mapping is generated from short-length signatures to entries in the first mapping; and verification of whether the cached page content corresponds to a full-length original logical block address using the metadata is performed.

  • Patent number: 9368602
    Abstract: Methods for fabricating an IGZO layer and fabricating TFT are provided in the present invention. The method for fabricating TFT includes the following steps: (1) depositing an IGZO layer and forming a surface oxidizing gas protective layer on the IGZO layer; (2) coating the IGZO layer with a photoresist, and then subjecting the photoresist to an exposing and developing process to form a photoresist pattern; and (3) subjecting the IGZO layer to an etching process, and then removing the photoresist. By forming an oxidizing gas protective layer, the present methods for fabricating an IGZO layer and fabricating TFT can effectively reduce the effect of hydrogen atom on IGZO layer and avoid the change of IGZO layer from semiconductor to conductor, thereby improving the stability of the IGZO layer and thus the TFT, and reducing the negative bias of threshold voltage generated by the long-term continuous use of the device.

  • Publication number: 20150272394
    Abstract: A blender includes a container, a cap, and a sealing module. The cap covers the container. The sealing module includes a mounting seat, a sealing member, a shaft, a valve, and an accessible member. The mounting seat is mounted movably on the cap. The sealing member is disposed in the container, and mounted to the mounting seat. The shaft extends through and is movable relative to the mounting seat, the cap and the sealing member, and has a lower end mounted co-movably to the valve. The accessible member is mounted on the mounting seat, is connected co-movably to the shaft, and is operable to move the shaft along the vertical axis so as to drive the valve between a release position and an air-tight position.

  • Patent number: 7473112
    Abstract: A flash memory device includes a main body, a cover and an elastic member connecting the main body and the cover. The main body includes a hinge protrusion formed thereon. The cover includes a tail and a pair of parallel plates facing each other and spaced by an interval corresponding to a thickness of the main body. At least one plate defines an opening for receiving the hinge protrusion so that the cover is rotatable with respect to the main body. The elastic member is fastened to the cover to abut against the protrusion, or fastened to the main body to abut against the cover, when the cover is rotatable relative to the main body.
