  • Patent number: 7323161
    Abstract: The patch for tooth whitening of the present invention includes a tooth-adhering layer (1) containing erodible polymer complexes formed by hydrogen bonding of a polymer with a carboxyl group (—COOH) and a polymer with a carbonyl group (—C?O) or ether group (—O—) and a tooth whitening agent; and an erosion rate-controlling layer (2) containing a mixture of a hydrophilic polymer and a film-forming polymer, wherein the patch is in a film form and is characterized by being eroded until extinguished after releasing the tooth whitening agent. When applied to the teeth, the patch releases a peroxide tooth-whitening agent while being hydrated by water in the mouth during a prescribed period, and thereafter, eroded until extinguished, thereby not requiring an additional detaching work from the teeth. Therefore, the patch is convenient in use and greatly reduces an obstruction sensation. Moreover, the patch has an excellent whitening effect.

  • Patent number: 7289098
    Abstract: A display apparatus having a backlight unit whose brightness is adjusted according to input image signals. The display apparatus processes input image signals in order for them to be appropriate to a display characteristic in an image signal processing unit and outputs each chromatic signal, R, G, and B, related to a color configuration of the image signals, processed in the chromatic signal output unit. Then a display panel drives an image display screen according to each chromatic signal. Meanwhile, a chromatic averaging unit calculates average brightness of the input images from each chromatic signal to transfer to a controller. The controller controls an inverter through an inverter current limiting unit in order for currents provided to the backlight unit in the display panel, to be controlled according to the average brightness of the input images calculated in the chromatic signal averaging unit.

  • Publication number: 20070122716
    Abstract: The present invention provides an organic/inorganic composite porous separator, which comprises: (a) a porous substrate having pores; and (b) an organic/inorganic composite layer formed by coating at least one region selected from the group consisting of a surface of the substrate and a part of pores present in the substrate with a mixture of inorganic porous particles and a binder polymer, wherein the inorganic porous particles have a plurality of macropores with a diameter of 50nm or greater in the particle itself thereby form a pore structure, a manufacturing method thereof, and an electrochemical device using the same. As an additional pathway for lithium ions is created due to a number of pores existing in the inorganic porous particle itself, degradation in the battery performance can be minimized, and energy density per unit weight can be increased by the weight loss effect.

  • Publication number: 20070087267
    Abstract: Disclosed is an electrode slurry comprising: (a) an electrode active material capable of lithium intercalation/deintercalation; and (b) monomers capable of forming a polymer via polymerization. An electrode having a binder polymer formed by applying the electrode slurry onto a current collector and carrying out in situ polymerization of the monomers, and an electrochemical device comprising the electrode are also disclosed. The electrode uses monomers capable of forming a binder polymer via polymerization under heat or light upon drying of the electrode, instead of the conventional PVdF or SBR-based binders. Therefore, it is possible to simplify a process for manufacturing an electrode, to provide an eco-friendly electrode by virtue of the use of an aqueous solvent as a dispersion medium, to improve the ion conductivity of a binder by virtue of the use of a solvent for a battery electrolyte as a dispersion medium, and thus to improve the quality of an electrochemical device.
