Patent ID: 8753431

Claim:
A bubble removal method for removing bubbles from liquid whose viscosity is reduced when shear occurs, comprising: using (1) a vessel that includes a liquid inlet and a plurality of liquid outlets and that has a variable volumetric capacity; (2) a device configured to increase and decrease the volumetric capacity of the vessel; and (3) a device configured to give resistance to passage of the liquid between inside and outside of the vessel; causing the liquid to pass through the vessel against the resistance; increasing and decreasing, by using the device configured to increase and decrease the volumetric capacity of the vessel, the volumetric capacity of the vessel; and causing the device configured to increase and decrease the volumetric capacity of the vessel and the device configured to give resistance to passage of liquid to depressurize and pressurize an interior of the vessel in conjunction with increase and decrease in the volumetric capacity of the vessel.
