Abstract: The present disclosure relates to a clock generator and a display device including the same. The clock generator includes a first clock generation circuit configured to output a clock, data, and a timing control signal; a first wiring through which the clock is serially transmitted; a second wiring through which the data is serially transmitted; a third wiring through which a pulse of the timing control signal is serially transmitted; a second clock generation circuit connected to the first clock generation circuit through the first wiring, the second wiring, and the third wiring and configured to generate pre-clocks in which phases are sequentially shifted based on the data and the clock; and a clock adjustment circuit configured to receive the pulse of the timing control signal and the pre-clock and output an output clock.

Abstract: The present invention relates to an anti-loosening bolt coupled to a bolt and a spring and, more specifically, to an anti-loosening bolt which can: prevent the bolt from being unintentionally loosened by a rotating object or by continuous long-time or momentary vibration; be fixed on a wall; be combined with a nut; prevent a periodic shaking phenomenon; and be reused.

Abstract: The present invention relates to titanium dioxide powder with a large specific surface area, a method for preparing thereof, and a use of the titanium dioxide as a photocatalyst, and more particularly, discloses a method for the preparation of titanium dioxide powder comprised of the steps of adding ice pieces or icy distilled water to pure titanium tetrachloride (TiCl4) to give an aqueous titanylchloride solution of 1.5 M or higher; diluting the aqueous titanylchloride with distilled water; obtaining precipitates from the diluted aqueous titanylchloride solution by standing for 2-20 hours at 15-70° C.; and filtering, washing and drying the above precipitates to give downy hair-shaped TiO2 powder with a specific surface area of 130-200 m2/g.

Abstract: A method for production of mono-dispersed and crystalline titanium dioxide ultra fine powders comprises preparing an aqueous titanyl chloride solution, diluting the aqueous titanyl chloride solution to a concentration of between about 0.2 to 1.2 mole and heating the diluted aqueous titanyl chloride solution and maintaining the solution in a temperature range of between 15 to 155.degree. C. to precipitate titanium dioxide. The aqueous titanyl chloride solution is prepared by adding ice pieces of distilled water or icing distilled water to undiluted titanium tetrachloride.
