  • Patent number: 9822448
    Abstract: Disclosed is a nanoparticle generating unit, a nanoparticle coating unit, and a core-shell nanoparticle collecting unit are connected to link and continuously process generation of nanoparticles and a coating and collecting process. The nanoparticle coating unit is formed of a porous material or in a grid structure and a moving speed of the nanoparticles can be decreased using a speed adjustment member installed at a process passage of a coating chamber.
    Type: Grant

  • Patent number: 9732425
    Abstract: Disclosed is a coating chamber having a process passage in which a coating process is performed, a particle supply means configured to supply nanoparticles into the process passage, a gas supply means configured to supply a carrier gas and a reactive gas serving as a source of a shell material into the process passage, and a low pressure forming means configured to form a low pressure in the process passage. The coating chamber has a speed adjustment member formed of a porous material or a grid and installed in the process passage, and as a moving speed of the nanoparticles is decreased due to flow resistance or collision of the nanoparticles passing through the speed adjustment member, first and second precursors supplied as the reactive gas move more rapidly than the nanoparticles to coat a thin film on the nanoparticles with the material.

  • Patent number: 8125692
    Abstract: An image forming device to scan a predetermined document includes a uniform block search unit to classify the object into a plurality of blocks and to search for uniform blocks having uniform inner pixel values, a status information detection unit to detect representative values of the inner pixel values of each of the uniform blocks searched for by the uniform block search unit and to output maximum and minimum values of the representative values, and a control unit to determine that the object is uniform if a difference between the maximum and the minimum values output from the status information detection unit is less than a predetermined threshold value. Accordingly, if the object is uniform it is possible to compensate for deterioration of screen quality by unifying the pixels of the object.

  • Patent number: 7609912
    Abstract: An image transforming apparatus and method include a linear interpolation block for generating linear interpolation information for a pixel to be interpolated between original pixels of a predetermined image; an edge information generating block for generating edge information and edge location information; a weight determining block for determining a weight for the linear interpolation information and the edge information of the interpolation pixel based on the edge location information; an interpolation information generating block for determining a pixel value of the interpolation pixel by reflecting the weight to the edge information and the linear interpolation information; and an interpolating block for generating the interpolation pixel based on the pixel value determined in the interpolation information generating block. Therefore, an image can be transformed into a high-resolution enlarged image with an edge area expressed clearly.
