  • Publication number: 20240145346
    Abstract: A semiconductor device includes a substrate with a conductive pattern. A semiconductor die is electrically connected to the substrate and both the semiconductor die and the substrate are at least partially covered by a package body. In some examples, through-mold vias are formed in the package body to provide electrical signal paths from an exterior surface thereof to the conductive pattern of the substrate. In some examples, through-mold vias are included in the package body to provide electrical signal paths between the semiconductor die and an exterior surface of the package body. In some examples, an interposer is electrically connected to the through-mold vias and may be covered by the package body and/or disposed in spaced relation thereto. In some examples, the interposer may not be electrically connected to the through-mold vias but may have one or more semiconductor dies of the semiconductor device electrically connected thereto.

  • Patent number: 11945744
    Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

  • Publication number: 20240067535
    Abstract: A water purifier includes: a filter module for providing purified water by filtering raw water; a fitting valve module detachably fastened to the filter module to provide at least one of a flow path for a flow of raw water supplied to the filter module and a flow path for a flow of the purified water discharged from the filter module; and a frame including a valve support for movably supporting the fitting valve module to be movable. The fitting valve module is selectively placed in a separated state in which the fitting valve module is separated from the filter module by moving in a direction away from the filter module, or a coupled state in which the fitting valve module coupled to the filter module by moving toward the filter module.

  • Publication number: 20120220647
    Abstract: A nanohybrid of the potent gene therapeutic agent siRNA (small interfering RNA) and a target-specific layered inorganic hydroxide, a preparation method thereof, and a pharmaceutical composition for tumor treatment containing the target-specific, siRNA/layered inorganic hydroxide nanohybrid. The nanohybrid increases the in vivo stability of the siRNA, and a target-specific multifunctional ligand, which is bonded to the layered inorganic hydroxide and can bind specifically to a tumor, increases the efficiency of tumor-specific transfer of the siRNA such that the siRNA shows tumor therapeutic activity even at a relatively low dose. Thus, the nanohybrid will be widely useful for target-specific antitumor therapies.

  • Publication number: 20110052842
    Abstract: The present invention relates to a receiving sheet for dye-sublimation thermal transfer recording and a method for manufacturing the same, and more particularly to a receiving sheet for dye-sublimation thermal transfer recording, which includes a base layer, a back coating layer formed on one surface of the base layer, and an ink-receiving layer formed on the surface opposite the surface of the base layer on which the back coating layer is formed, the ink-receiving layer containing porous metal oxide nanoparticles, and a method for manufacturing the same. The inventive receiving sheet for dye-sublimation thermal transfer recording includes the ink-receiving layer containing porous metal oxide nanoparticles. Thus, the resolution of images on the receiving sheet can be maintained, while the resistance to thermal deformation and durability of the receiving sheet can be greatly improved, thus offering many advantages in terms of image quality or cost.
