  • Publication number: 20070170008
    Abstract: The present invention pertains to an elevator landing door system having a fire prevention device that prevents flame or smoke from penetrating into a shaft (60) from a landing and being spread throughout the entire building by blocking the gap between door panels (11, 11?) when a fire breaks out in a building. The elevator landing door system having a fire prevention device consists of door panels (11, 11?) that are opened and closed; a fire prevention plate (40) that extends alongside the opening and closing edge surface (11b) of one door panel (11) on the side (11b) facing the elevator, equipped with a downward slot (42) inclined toward the opening and closing edge of the door panel, and fixed to the door panel by a fastening means (46) penetrating through the slot; and fixtures (44) made of a fusible material that are tightly attached together with the door panel and the fire prevention plate by the fastening means.

  • Publication number: 20070128540
    Abstract: A photoresist resin composition comprises about 10 to about 35% by weight of an acryl-based copolymer, about 5 to about 10% by weight of a quinone diazide compound, about 55 to about 80% by weight of a solvent, and about 0.01 to about 0.5% by weight of a silane-based surfactant where the weights of each of the acryl-based copolymer, quinone diazide compound, solvent, and silane-based surfactant are based on the total weight of acryl-based copolymer, quinone diazide compound, solvent, and silane-based surfactant. An overcoating layer formed using the photoresist resin composition has improved flatness, and thus defects on a display screen may be prevented and/or reduced.

  • Publication number: 20060079012
    Abstract: A carbon nanotube emitter and a method of manufacturing a carbon nanotube field emission device using the carbon nanotube emitter. Powdered carbon nanotubes are adsorbed onto a first substrate. A metal is deposited on the carbon nanotubes. The resultant structure is pressure-bonded to a surface of a cathode. The first substrate is spaced apart from a second substrate to tense the carbon nanotubes, so that the carbon nanotubes are perpendicular to the first substrate.

  • Patent number: 7025652
    Abstract: An electron amplifier and a method of manufacturing the same are provided. The electron amplifier includes a substrate in which a plurality of through holes are formed, a resistive layer deposited on the sidewalls of the through holes, an electron emissive layer including carbon nanotubes which is deposited on the resistive layer, and an electrode layer formed on each of the upper and lower sides of the substrate. Because the electron emissive layer of the electron amplifier is uniform and provides a high electron emission efficiency, the electron amplification efficiency is improved. The electron amplifier manufacturing method enables economical mass production of electron amplifiers.

  • Publication number: 20060067240
    Abstract: An apparatus for detecting a network traffic abnormality includes: a pre-processing unit pre-processing traffics collected from at least one traffic collecting point in a network; a profiler modeling a normal traffic according to a characteristic of the traffic; an analysis model unit generating the thresholds based on the traffic; and an analyzer comparing a relative ratio of the traffic to the entire network traffics and the threshold and determining whether the traffic is abnormal. A combinational use of analysis methods using the relative ratio to the entire traffics and the absolute traffic volume takes into consideration of characteristics of a relative traffic ratio and absolute traffic volume, thereby providing a more reliable determination on whether the traffic is abnormal.

  • Publication number: 20050138425
    Abstract: Provided is a method for analyzing a network attack situation. The method categorizes network intrusion detection alerts into network attack situations, counts the frequency of same-featured intrusion alert occurrence for each network attack situation using a counting algorithm based on time slots, and analyzes the network attack situation based on the frequency of same-featured intrusion detection alert occurrence, the rate of same-featured intrusion detection alert occurrence, or an AND/OR combination of them. The network attack situation can be correctly detected in real time without relatively being influenced by the size of the network or amount of the occurrence of the intrusion detection alerts.
