CONSTITUTION: The photocatalyst is prepared by the following procedure: 7ml of a 20% tetrabutyl- ammoniumhydroxide ((CH3(CH2)3)4NOH; TBAOH) solution and 6-2.66ml of a tetraethyl-orthosilicate (Si(OC2H5)4; TEOS) is stirred homogeneously for 30minutes. And 0.76-4.58g of tetrabutyl-orthotitanate (Ti(O(CH2)3CH3)4; TBOT) as a titanium precursor is dissolved in 5ml of isopropyl-alcohol and added slowly into the previous mixture. In order to remove the contained alcohol, the solution is heated at 80±2deg.C for 2hours. And after 9.6ml of water is added, the solution is crystallized in the autoclave reactor under the reaction conditions of 175deg.C for 24hours. The crystallized powder is gained by water washing and a drying at 110deg.C for 24hours. And the final catalyst is prepared by a calcination process of 500deg.C for 5hours.

Abstract: PURPOSE: A method for 3-dimensional measuring load is provided to measure level of raw material loaded in a bin by using three point sensors. CONSTITUTION: By using three point sensors, level of powder raw material is measured. Modeling of the logical values of the measured levels is performed. The modeled values are compared with the measured level values from the point sensors. In case of identification of the values, the logical level values are established as a three-dimensional loaded shape. Herein, the point sensors are installed at left and right sides and a center of a tank. Moreover, the sensors face toward center of lower surface of the tank.

Abstract: PURPOSE: An apparatus is provided to distinguish a degree of charge-up induced to a pattern by a plasma process, by repeatedly scanning primary electron beams, and by measuring a variation of the quantity of the emitted secondary electrons. CONSTITUTION: A plasma process is completed regarding a wafer(110). An electron beam generating unit(310) generates a primary electron beam which repeatedly scans a predetermined region of the surface of the wafer. A detecting unit(400) is separated from the wafer by a predetermined interval, and collects secondary electrons(250) emitted to the exterior of the surface of the wafer, The secondary electrons are generated by a reaction between the primary electron beam and the surface of the wafer. From a variation of the quantity of the secondary electrons collected at the detecting unit, a distinguishing unit(500) distinguishes a degree of charge-up induced to the surface of the wafer by plasma used in the plasma process.
