  • Patent number: 11973022
    Abstract: A semiconductor device includes a line; a source structure on the line; a stack structure on the source structure; a first slit structure penetrating the stack structure; a second slit structure penetrating the stack structure; and a contact plug adjacent to the first slit structure in a first direction. The first slit structure and the second slit structure may be spaced apart from each other by a first distance in a second direction that is perpendicular to the first direction. The contact plug penetrates the source structure, the contact plug being electrically connected to the lower line. The first slit structure and the contact plug may be spaced apart from each other by a second distance in the first direction, and the second distance may be longer than the first distance.

  • Patent number: 11962001
    Abstract: Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

  • Publication number: 20240106073
    Abstract: Provided are a separator coating composition for a secondary battery including inorganic particles and a silane salt compound having a specific structure, a separator using the same, and an electrochemical device including the same. Specifically, a separator coating composition for a secondary battery which implements adhesion between an inorganic material layer and a porous substrate without including an acid/polymer-based organic binder in a coating composition for forming the inorganic material layer on one or both surfaces of the porous substrate and does not need a separate dispersing agent for dispersing the inorganic particles, a separator manufactured using the same, and an electrochemical device including the separator are provided.

  • Patent number: 6955691
    Abstract: An expandable interfusion cage comprising a cage body and a spacer. The cage body includes a seat part which is pierced by an orifice and a branch part which defines therein an inside space and has a plurality of elongate branches integrally formed at their proximal ends with the seat part. An opening is defined between two adjoining branches to communicate with the inside space. The spacer is movably assembled in the inside space of the cage body to expand the cage body radially outward. Inward projections are formed at distal ends, respectively, of the branches to project radially inward toward an axis of the cage body. The inside space of the cage body has substantially a circular or polygonal sectional shape. The spacer is engaged with the inward projections of the branches while expanding the cage body.

  • Patent number: 6917811
    Abstract: Provided is a real-time dynamic channel assignment method based on a genetic algorithm in a radio communication system, and a computer-readable recording medium for recording a program implementing the method. The channel assignment method in accordance with the present invention has following advantages. First, an evaluation function clearly shows the difference between chromosomes, which represents channel assignment, can be set. Second, the efficiency in calculation time and memory capacity is increased by representing the assignment of channels arranged in one-dimensional using inherent channel numbers. Third, by controlling the Elitist pool crossover method and mutation probability properly, diversity is pursued in the initial process of the evolution program, and then as generation repeats, the convergence is enhanced so as to increase the efficiency in obtaining the optimum solution.
