  • Patent number: 8236251
    Abstract: Suppression or enhancement of various properties of a liquid fluid is aimed by improving uniform dispersion of nanoparticles by means of making a state in which no oxidized film exists on the surfaces of the nanoparticles to be dispersed in the liquid fluid. The location of the liquid fluid is confirmed with ease by enhancing the brightness of light emission of the fluid through uniform dispersion of the nanoparticles in the liquid fluid containing a material having a flame reaction. In this way, as to liquid fluids utilized in various industries, it is possible to offer a technology to desirably enhance or suppress a property desired to be enhanced and a property desired to be suppressed among various properties that its constituents have.

  • Publication number: 20040231766
    Abstract: A propulsion device operated in a bi-propellant mode uses a safe hydrogen peroxide as oxidizer and yet has high specific impulse and high response performance. A preheated net 18 is provided in a combustion chamber 14. Both of an oxidizer supply means 10 and a fuel supply means 12 open toward the net 18. Oxidizer 30 and fuel 32 are atomized on the net 18 to thereby increase the surface area. At the same time, the oxidizer 30 and fuel 32 are heated on the net 18 and their decomposition is accelerated. By quickly effecting collision and mixing of the oxidizer 30 with the fuel 32, an instantaneous ignitability can be obtained.

  • Patent number: 5702505
    Abstract: A method for collecting volatile organic substances from an off-gas containing moisture and volatile organic substances. The organic substances are removed from the gas containing the organic substances and the moisture by introducing the gas into an adsorbing tower filled with the adsorbents and being in the adsorbing process under a relatively low temperature condition. The gas is discharged outside the system as the gas containing the moisture but from which the organic substances have been removed. The organic substances are desorbed under a relatively high temperature condition in the regenerating process for the regeneration. The moisture is removed from the desorbed gas discharged from the adsorbent regenerating process in a dehumidifying tower filled with the moisture absorbent by the temperature swing method or pressure swing method.
