  • Applicator and method for transferring dispersion liquid
    Patent number: 8171876
    Abstract: The present invention provides applicators reducing generating bubble. Dispersion liquid is supplied while the pressure of a circulation tank on the delivery side is lower than the atmospheric pressure but higher than the pressure of the space in buffer tanks. The dispersion liquid in the discharge chambers is recovered while the pressure in a circulation tank serving as recovery destination is lower than the atmospheric pressure. Gas dissolution can be reduced because the dispersion liquid does not come into contact with gases at pressures higher than the atmospheric pressure and engulffing gas or deformation of solid microparticles can be avoided because no pump is used.
    Type: Grant
