  • Publication number: 20160040814
    Abstract: The present invention relates to a tube-fitting structure for a pure-water line of a water purifier or refrigerator. The present invention provides a tube connecting structure in which a tube fitted into a body having a fitting part formed therein is fixed by a cap, wherein a guide groove formed to have a receiving recess curved downward is formed on an outer circumferential surface of a tube link part of the body, and wherein a guide protrusion is formed on an inner circumferential surface of the tube corresponding to the outer circumferential surface of the body to allow the guide protrusion to be coupled along the guide groove, so that the tube is easily assembled with the body while the cap is rotated due to an inclined surface of the guide groove. Thus, in spite of enhancing the air tightness of the fitting structure, the assembly is improved.

  • Publication number: 20140018583
    Abstract: Embodiments of the inventive concept provide a successive gas hydrate manufacturing method, without hydration after generating gas hydrate slurry, capable of operating with a higher conversion rate and relatively low hydrate generation pressure and reducing a product cost by decreasing the number of processing steps for removing heat of reaction, for which the total exothermic value downs due to no need of latent heat according to a phase change rather than the case of generating a gas hydrate directly from a water solution, as well as making gas diffusion easier during reaction of generation and maximizing a contact area between water and gas to increase a gas capture rate and shorten the total hydrate generation time.

  • Patent number: 8200855
    Abstract: Methods and systems are disclosed for detecting DisplayPort (DP) source device connection to sink devices. When the DP link is active, no measurements are made to determine source device connections. When a DP link is not active, a signal line for the auxiliary channel for a DP connection is measured to determine if a source device is connected. More particularly, the auxiliary channel is a differential auxiliary channel, and the positive signal line is measured to make the determination of whether a source device is connected. Still further, an indication is made that a source device is connected if the positive signal line is at a low level, and an indication is made that a source device is not connected if the positive signal line is at a high level.

  • Patent number: 8111799
    Abstract: A method for reducing power consumption in an information handling system (IHS) where the method includes receiving main data through a main link, wherein the main link provides at least one data lane. The IHS also receives a reference clock corresponding to the main data through an auxiliary channel and provides the reference clock to a first phase-lock loop, wherein the first phase-lock loop outputs a stream clock.

  • Publication number: 20100183818
    Abstract: Provided are an apparatus and a method of depositing films capable of controlling deposition rate and film properties using the charging behavior of nanoparticles formed in gas phase. The apparatus includes a chamber in which a substrate is loaded, a gas supply system configured to introduce a reaction gas into the chamber, a filament configured to emit heat for dissociating the introduced reaction gas, a power supply configured to apply a constant alternate current or direct current voltage, and a bias supply unit configured to apply a bias to at least one of a top, a side and a bottom of the substrate using a voltage applied from the power supply while a film is deposited on the substrate from the dissociated reaction gas, the bias supply unit being separated from the substrate.

  • Patent number: 7619167
    Abstract: Disclosed is a fiber reinforced plastic wire used as the overhead transmission cable. The fiber reinforced plastic wire for a strength member of an overhead transmission cable according to the present invention includes a wire having a predetermined diameter and composed of thermoset matrix resin; and a plurality of high strength fibers dispersed parallel to a longitudinal direction in an inside of the wire, the high strength fibers being surface-treated with a coupling agent to improve interfacial adhesion to the matrix resin. The fiber reinforced plastic wire of the present invention has the high tensile strength at the room temperature and the high temperature since its high strength fiber is surface-treated with a coupling agent. The fiber reinforced plastic wire can be also effectively used as the strength member in the overhead transmission cable since it has the excellent low coefficient of thermal expansion, etc. and is light-weight.
