Provided are a high strength thin steel sheet having tensile strength of about 800 MPa or more, and a manufacturing method thereof. The thin steel sheet is mainly used for construction materials, home appliances, and automobiles. The thin steel sheet has excellent plating characteristic, welding characteristic, bending workability, and hole expansion ratio. The thin steel sheet includes, in weight %, C: 0.02-0.20%, Si: 1.5% or less, Mn: 1.5-3.0%, P: 0.001-0.10%, S: 0.010% or less, SoLAl: 0.01-0.40%, N: 0.020% or less, Cr: 0.3-1.5%, B: 0.0010-0.0060%, Sb: 0.001-0.10%, and including at least one material selected from the group consisting of Ti: 0.003-0.08%, Nb: 0.003-0.08%, and Mo: 0.003-0.08%, and includes Fe and other inevitable impurities as a remainder. Here, Si, Mn, B, Sb, P, and S meet conditions of 5

A platelet-type zirconium phosphate, which has a P—OH group contained in a structure thereof, and has a crystalline peak at a 2θ value of 11.6±2 degrees and no crystalline peak at a 2θ value of less than 11.6±2 degrees in X-ray diffraction analysis, is provided. The platelet-type zirconium phosphate has a platelet-type structure and can be uniformly dispersed at a nanoscale level in a coating film to exhibit excellent surface gloss and barrier capability. Also, the platelet-type zirconium phosphate can exhibit excellent corrosion resistance due to the presence of the P—OH group on a surface thereof, and can be dispersed not only in an aqueous solution but also in an organic solvent.

A circular filtering disc and a filter device having the filtering disc. The filtering disc includes a circular partition plate having an inner hub and an outer rim, with radial inlet holes formed in the outer rim and introducing water to the partition plate, and a vertical outlet hole formed in the center of the inner hub and discharging pure water; and a filter fabric placed on or below the partition plate, wherein water supplied to the filtering disc passes through the filter fabric and becomes concentrated at the vertical outlet hole, and is discharged from the filtering disc through the vertical outlet hole. In the filter device, raw water is supplied through the circumferential edges of the circular filtering discs stacked on top of one another in the filter device and is filtered prior to being discharged from the filter device through the center of the filtering discs.

Disclosed herein is a gap sensor enabling the mounting of a syringe. The gap sensor includes an emitting part and a receiving part for measuring a distance to a substrate. A syringe mounting unit is integrally provided between the receiving part and the emitting part, so that the lower end of the syringe is inserted into and secured to the syringe mounting unit. The syringe mounting unit includes a mounting hole which holds the syringe to keep a distance between a laser beam spot formed by the emitting part and the receiving part and an outlet of the syringe constant, when the syringe is inserted into and secured to the syringe mounting unit. The syringe is directly inserted into the gap sensor to be secured thereto, thus enabling the convenient replacement of the syringe, and minimizing an error between the sensor and the outlet of the syringe which may occur during the replacement of the syringe, therefore allowing the syringe to be more precisely mounted.
