Abstract: A deposition apparatus including: a base substrate; an electrostatic chuck on the base substrate; and a plate on the electrostatic chuck. The plate has a first area in which first magnet units are arranged and a second area in which second magnet units are arranged. The first magnet units are spaced apart from each other at a first distance, and the second magnet units are spaced apart from each other at a second distance. The second distance is greater than the first distance.

Abstract: An embodiment vehicle air conditioner includes an air conditioning device connected to a blower device to receive air supplied from the blower device, a heat exchange core provided in the air conditioning device and disposed in parallel with a flow direction of the air supplied from the blower device, a partition wall disposed to divide the heat exchange core into a first core part disposed to be close in distance to the blower device and a second core part disposed to be distant from the blower device, such that the air supplied from the blower device is distributed and supplied to the first core part and the second core part, and an air guide provided in a connection portion between the blower device and the air conditioning device and configured to guide the air to be supplied to the second core part of the heat exchange core.

Abstract: Disclosed is a surface-penetration reinforcing agent that is used to effectively repair a damaged reinforced concrete structure. The surface-penetration reinforcing agent includes a silicate compound, an acrylate monomer, an amine compound and a silane compound as reactants. Further disclosed is a method for repairing a damaged reinforced concrete structure using the surface-penetration reinforcing agent depending on the aging grade of the reinforced concrete structure. According to the repair method, the surface-penetration reinforcing agent can be used to efficiently repair a damaged reinforced concrete structure depending on the aging grade of the reinforced concrete structure classified by whether or not the reinforcing bars are corroded in damaged portions of the concrete and the degree of carbonation in the concrete.

Abstract: A penetration reinforcing agent for preventing aging of concrete is prepared by using an inorganic silicate compound having an ethoxy or methoxy group and a monomer having a hydroxyl (OH) group. When the penetration reinforcing agent is applied onto the surface of a concrete structure it penetrates the concrete structure where it is hydrolyzed by water existing within the concrete to form silica (SiO2) having a particle size of several nanometers, is gelled by a sol-gel process and reacts with concrete hydrates, so that internal pores of the concrete structure are compactly filled with the reaction products. The penetration reinforcing agent is effective in enhancing the strength of, inhibiting penetration of aging factors into, improving waterproofness of, and preventing neutralization of the concrete structure.

Abstract: Disclosed herein is a penetration reinforcing agent for preventing aging of concrete. The penetration reinforcing agent is prepared by using an inorganic silicate compound having an ethoxy or methoxy group and a monomer having a hydroxyl (OH) group. When the penetration reinforcing agent is applied onto the surface of a concrete structure by using a spray gun or a brush, it penetrates the concrete structure where it is hydrolyzed by water existing within the concrete to form silica (SiO2) having a particle size of several nanometers, is gelled by a sol-gel process and reacts with concrete hydrates, so that internal pores of the concrete structure are compactly filled with the reaction products. Therefore, the penetration reinforcing agent is effective in enhancing the strength of the concrete structure, inhibiting penetration of aging factors into the concrete structure, improving waterproofness of the concrete structure and preventing neutralization of the concrete structure.

Abstract: A substrate delivering apparatus that delivers a substrate includes a base part, a moving part mounted on the base part so as to perform linear movement and having a rotating body, a pair of frame parts mounted in parallel on opposite sides of the moving part and having heights that are adjustable, and a delivering part that is connected between the pair of frame parts and is vertically displaced according to an adjustment of the heights of the frame parts. Thus, the substrate delivering apparatus is capable of facilitating delivery of a substrate while maintaining structural stability.

Abstract: A strain measurement system includes a tunable light generator, a coupler, a fiberoptic sensor unit, and an optical detector. The tunable light generator includes a Super Luminescent light emission Diode (SLD), and a tunable Fabry-Perrot (FP) filter cascaded to an output terminal of the SLD to convert light having a wideband spectrum into discrete optical signals. The coupler receives and distributes the optical signals and passes them to a wavelength compensation device which detects wavelengths of the optical signals. The fiberoptic sensor unit receives the optical signals from the tunable light generator through the coupler and transmits a response signal corresponding to a variation of strain attributable to load. The optical detector detects the response signal output from the fiberoptic sensor through the coupler.
