  • Patent number: 11932993
    Abstract: A paper coating composition, methods for making the same, and a coated paper. The paper coating composition comprises a solvent, an ethylene-(meth)acrylic acid copolymer, a basic compound, and a polycarbodiimide-based curing agent, wherein the polycarbodiimide-based curing agent has a carbodiimide group equivalent of about 150 to about 350. The coating of the coated paper likewise comprises an ethylene-(meth)acrylic acid copolymer crosslinked by N-acylurea groups.

  • Publication number: 20240088361
    Abstract: A lithium secondary battery includes a cathode including a cathode current collector and a cathode active material layer formed on the cathode current collector, and an anode including an anode current collector and an anode active material layer formed on the anode current collector. The anode active material layer has an area larger than that of the cathode active material layer. The cathode active material layer includes a central portion and an outer portion surrounding the central portion, and the outer portion has a specific capacity less than that of the central portion.

  • Patent number: 8304898
    Abstract: An integrated circuit package system includes: connecting a first interconnect between a carrier and a bottom integrated circuit thereover; forming a film, having an overhang portion, over the bottom integrated circuit with the overhang portion over the first interconnect; mounting a top integrated circuit over the film; connecting a second interconnect between the top integrated circuit and the carrier with the overhang portion between the first interconnect and the second interconnect; and forming an encapsulation over the carrier covering the top integrated circuit, the film, the first interconnect, and the second interconnect.

  • Patent number: 7831740
    Abstract: A control circuit used to transfer data to a programmable memory in an electronic device can be separate from a general operation processor circuit that controls general operations of the electronic device. The controller circuit may allow a transfer of data to the programmable memory without the use of Random Access Memory (RAM) or a Read Only Memory (ROM) that is under the control of the general operation processor circuit. The general operation processor circuit can be disabled by the controller circuit while data is transferred (i.e. programmed to) programmable memory.

  • Patent number: 7719614
    Abstract: In an apparatus and method for converting the frame rate of an image signal in a display system without an external memory, the display system and method are capable of down converting the frame rate of an image signal using a frame rate conversion unit without an external memory. The system and method can be used even in the case where the frequencies of input and output synchronization signals are locked to the same frame rate. The frame rate conversion unit disable-masks portions of the frames of a data enable signal or a vertical synchronization signal, thus canceling the portions of the frames, and outputs the masked data enable signal or the masked vertical synchronization signal to an LCD driving circuit unit, thereby down converting the frame rate of the image signal.
