Abstract: Disclosed are heat-ray cutoff compounds, films and method using them. The heat-ray compound is produced by dispersing conductive nanoparticles in an amphoteric solvent with acids and dispersion sol, which provides a low cost production for the heat-ray cutoff films because it is able to any resin binder without sorting the kinds of resin binders (hydrolic or alcoholic, or anti-hydrolic).

Abstract: The present invention relates to compositions for functional films, and more particularly to compositions for functional films such as a heat ray screening film compatible with hydrolic or alcoholic and anti-hydrolic resin binder, a near infrared screening film, a chrominance correcting film, a conductive film, a magnetic film, a ferromagnetic film, a dielectric film, a ferroelectric film, an electrochromic film, an electroluminescence film, an insulating film, a reflecting film, a reflection preventing film, a catalyst film, a photocatalyst film, a light selectively absorbing film, a hard film, and a heat resisting film, films formed therefrom, and a method of forming the compositions and the films.

Abstract: A water injection device for injecting water into the combustion chambers of an engine is disclosed. Water particles are injected through a system other than the fuel injection nozzle, and the water is injected through a suction system, but as to the injection of the water particles, the injection rate and injection time are optimally controlled in accordance with the internal situations of the combustion chambers.
