  • Publication number: 20110073666
    Abstract: The present invention relates to a boiler system with dual hot water tanks. More specifically, the invention provides a boiler system with dual hot water tanks wherein one boiler comprises high-temperature and low-temperature water tanks. The invention mixes high-temperature water in the high-temperature tank with low-temperature water in the low-temperature tank at different flow rates in a mixing valve, and supplies hot water at a preset temperature to a water supply heat exchanger so the temperature of the heated water in the water supply heat exchanger is constantly maintained. The present invention can supply hot water at a constant temperature always suitable for use and is free from inconvenience or discomfort caused by thermal deviation, because hot water at a temperature higher or lower than the preset temperature is mixed with the preset-temperature water, and then supplied to the water supply heat exchanger.

  • Patent number: 7817236
    Abstract: A display substrate includes a transparent plate and a liquid crystal dispersion adjuster. The display substrate includes a display area and a peripheral area surrounding the display area. The liquid crystal dispersion adjuster is formed in the peripheral area to modify the movement of the liquid crystal. The dispersion adjuster includes enhancing parts and a suppression part. The enhancing parts increase the dispersion of the liquid crystal, and the suppression part reduces the dispersion of the liquid crystal, thereby reducing non-filling area of the liquid crystal and the contamination of a seal-line.

  • Publication number: 20090262285
    Abstract: In a method of fabricating a liquid crystal display device, when a photoresist film formed on a substrate for the liquid crystal display device is exposed and developed, protrusions are formed on the substrate for increasing a viewing angle of the liquid crystal display device. Although the substrate is formed with step differences thereon caused by various intermediate films, the protrusions may have a same size since an exposure amount to the photoresist film is varied according to the step differences of the substrate on which the protrusions are formed. Thus, the liquid crystal display device may have an improved display quality.
