Abstract: The inventive concept provides a substrate treating apparatus. The substrate treating apparatus includes a support unit configured to support a substrate; and a cleaning unit configured to clean a bottom surface of the substrate supported on the support unit, and wherein the cleaning unit comprises: a body; and a protrusion formed to be upwardly protruding from the body, and the protrusion is positioned to be spaced apart from the bottom surface.

Abstract: The present invention relates to a method of non-destructively measuring a thickness of a reinforcement membrane, and more particularly, to a method of non-destructively measuring a thickness of a hydrogen ion exchange reinforcement membrane for a fuel cell, in which the reinforcement membrane has a symmetric three-layer structure including a reinforcement base layer and pure water layers disposed at opposing sides of the reinforcement base layer, including performing total non-destructive inspection and omitting a process of analyzing a position by means of a thickness peak of a power spectrum of the respective layers of the reinforcement membrane.

Abstract: Provided is a method of preparing noodles with enhanced cooking convenience. Noodles according to the present invention can be immediately cooked without an additional boiling process.

Abstract: This ultra-low-loss optical fiber comprises a core having a higher relative refractive index difference than silica and a cladding having a lower relative refractive index difference than silica. The relative refractive index difference of the core with respect to the refractive index of silica is 0.0030 to 0.0055, for example, and the relative refractive index difference of the cladding with respect to the refractive index of silica is ?0.0020 to ?0.0003. The ultra-low-loss optical fiber has the loss characteristic of simultaneously having optical losses of at most 0.324 dB/km at a wavelength of 1310 nm, at most 0.320 dB/km at a wavelength of 1383 nm, at most 0.184 dB/km at a wavelength of 1550 nm, and at most 0.20 dB/km at a wavelength of 1625 nm. The ultra-low-loss optical fiber is supercooled when the surface temperature of the optical fiber has a temperature range in a glass transition section during drawing.

Abstract: This invention relates to tacrolimus injection comprising tacrolimus as an active ingredient, macrogol 15 hydroxystearate as a surfactant and a non-aqueous solvent.

Abstract: The present invention relates to the carrier of the solid dispersion of tacrolimus, which is prepared by using the solid surfactant having a property of HLB value higher than or equal to about 7. The surfactants carry out a function of a carrier and a function of a dissolution enhancer, simultaneously. As a result, the dissolution rate of tacrolimus is improved, and the oral absorbability and the bioavailability may be increased due to rapid drug release.
