Abstract: A method of manufacturing a neutral and transparent metal oxide colloid solution containing dispersed titanium dioxide nano particles comprising the steps of (i) adding a titanium compound and a stabilizer to alcohol to produce a titanium-containing solution and (ii) neutralizing the titanium-containing solution of step (i) by adding a basic solution to produce a neutralized solution with the pH of the neutralized solution in a range of 6-8; and (iii) heating the neutralized solution at a temperature of above 75° C.

Abstract: The present invention relates to a method of manufacturing a neutral and transparent titanium dioxide colloid solution wherein titanium dioxide nano particles is dispersed, and a novel titanium dioxide colloid solution prepared by the method. In addition, the present invention relates to a multifunctional, normal temperature curing-type coating agent comprising the titanium dioxide colloid solution.

Abstract: The object of this invention is to provide a toy vehicle, having a permanent magnet ring (55, 65) fixedly fitted over each of the front and rear wheels. This toy vehicle (100, 200, 300 or 400) is thus movable on a magnetic slope surface and a metal vertical wall in addition to a horizontal surface. The toy vehicle has a V-shaped groove (15) through the center on its bottom between the front and rear wheels, thus being movable on a metal stairway while climbing over the top corner of each step of the stairway. The toy vehicle is further provided with a floater (80) on its body and a plurality of vanes (95) on each wheel,thus being movable on the surface of the water. This toy vehicle easily moves on the rails between two or more sections as desired, thus more effectively getting children interested in playing such toy vehicles.
