  • Patent number: 11940734
    Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a chamber having a treating space therein; a supply line having a first open/close valve installed thereon and configured to supply a treating fluid to the treating space; a heater installed on the supply line and configured to heat the treating fluid; an exhaust line having a second open/close valve installed thereon and configured to exhaust the treating space; and, a controller configured to control the first open/close value and the second open/close valve such that the treating fluid heated is supplied to and exhausted from the treating space before a treating process is performed on a substrate in the treating space.

  • Publication number: 20240073416
    Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

  • Patent number: 11917193
    Abstract: According to the present invention, an image encoding apparatus comprises: a motion prediction unit which derives motion information on a current block in the form of the motion information including L0 motion information and L1 motion information; a motion compensation unit which performs a motion compensation for the current block on the basis of at least one of the L0 motion information and L1 motion information so as to generate a prediction block corresponding to the current block; and a restoration block generating unit which generates a restoration block corresponding to the current block based on the prediction block. According to the present invention, image encoding efficiency can be improved.

  • Publication number: 20120107683
    Abstract: A composite of electrode active material including aggregates formed by self-assembly of electrode active material nanoparticles and carbon nanotubes, and a fabrication method thereof are disclosed. This composite is in the form of a network in which at least some of the carbon nanotubes connect two or more aggregates that are not directly contacting each other, creating an entangled structure in which a plurality of aggregates and a plurality of carbon nanotube strands are intertwined. Due to the highly conductive properties of the carbon nanotubes in this composite, charge carriers can be rapidly transferred between the self-assembled aggregates. This composite may be prepared by preparing a dispersion in which the nanoparticles and/or carbon nanotubes are dispersed without any organic binders, simultaneously spraying the nanoparticles and the carbon nanotubes on a current collector through electrospray, and then subjecting the composite material formed on the current collector to a heat treatment.
