Abstract
In an apparatus for defoaming liquid with ultrasonic wave in order to eliminate foam or bubble from the liquid, provided with an ultrasonic wave liquid tank, a defoaming tank, and an ultrasonic oscillator for irradiating ultrasonic wave through the ultrasonic wave transmitting liquid to the defoaming tank; at least a part of the defoaming tank is immersed in the ultrasonic wave transmitting liquid in the ultrasonic wave liquid tank, and a degree of unsaturation of dissolved air in the ultrasonic wave transmitting liquid under defoaming operation is not lower than 10%.
Claims27
A method of defoaming liquid with ultrasonic wave in order to eliminate foam or bubble from the liquid, comprising steps of:
- storing liquid to be defoamed in a defoaming tank;
- and
- irradiating ultrasonic wave through ultrasonic wave transmitting liquid to the defoaming tank in which the liquid to be defoamed is stored;
- wherein a degree of unsaturation of dissolved air in the ultrasonic wave transmitting liquid under defoaming operation is not lower than 10%.
A method of producing a light sensitive material in order to eliminate foam or bubble from the liquid, comprising steps of:
- storing liquid to be coated onto the light sensitive material in a defoaming tank;
- irradiating ultrasonic wave through ultrasonic wave transmitting liquid to the defoaming tank in which the liquid is stored so that the liquid to be coated is defoamed;
- and
- coating the defoamed liquid onto a support of the light sensitive material;
- wherein a degree of unsaturation of dissolved air in the ultrasonic wave transmitting liquid under defoaming operation is not lower than 10%.
An apparatus for defoaming liquid with ultrasonic wave in order to eliminate foam or bubble from the liquid comprising:
- an ultrasonic wave liquid tank in which an ultrasonic wave transmitting liquid is stored;
- a defoaming tank in which a liquid to be defoamed is stored, at least a part of the defoaming tank immersed in the ultrasonic wave transmitting liquid in the ultrasonic wave liquid tank;
- a deaerating device to deaerate the ultrasonic wave transmitting liquid so as to make the degree of unsaturation of dissolved air in the ultrasonic wave transmitting liquid under defoaming operation not lower than 10%.
