Abstract: Buildings surfaces are often seen subjected to application of heat insulation paint. When the surface of buildings gets dirty, reflectivity of the light lowers, so that the surface of buildings is likely to adsorb heat, resulting in lowering of the heat insulation effect. The present invention has such object of providing a paint that the tasks of prevention of getting dirty and provision of heat insulation are achieved, decomposition of resin is much lowered, and applying the paint is readily carried out. An emulsion type paint comprising: an organic hollow balloon A having on the surface photo-catalyst minute particles stuck by heat fusion, an organic hollow balloon B having on the surface minute particles other than photo-catalyst stuck by the similar manner, and an organic resin, colloidal silica, and water, characterized in that the organic hollow balloon B is higher in specific gravity than the organic hollow balloon A.

Abstract: A roller coaster device which can operate a seat together with a car to perform a perpendicular running motion such as vertical descent, vertical ascent, vertical spiral motion and the like, or in such a manner as to run backwards. The device significantly increases thrill and interest levels by creating the sensation that the endless running rail suddenly disappears from the view of the occupants in the roller coaster device. The device can be configured in a small space and in a compact manner. A car (4) is mounted on the endless running rail (1) having a desired length that is provided in a rolling and bending manner through rollers (6) so as to run freely while being held thereto, and seats (11a, 11b) are suspended on the car 4 by mounting members (12a, 12b) so as to rotate freely.
