System for ultrasonic wave type bubble removal
First Claim
1. A method of ultrasonic wave type bubble removing for removing bubbles from a first liquid by imparting ultrasonic wave vibration to said first liquid, comprising the steps of:
- disposing a part of a liquid conduit in an ultrasonic wave liquid tank which is provided with an ultrasonic wave oscillator and is filled with an ultrasonic wave propagating liquid;
delivering said first liquid through said part of said conduit without a vapor-liquid interface in said conduit and while maintaining an absolute pressure of 1.3 Kg/cm2 or higher inside side liquid conduit; and
generating ultrasonic wave vibration by said ultrasonic wave oscillator and imparting said vibration to said first liquid in said liquid pipe to dissolve the bubbles in said first liquid and prevent deposition of bubbles under the atmospheric pressure.

Abstract
An ultrasonic wave type bubble removing system for removing bubbles from a first liquid from which bubbles should be removed, by imparting ultrasonic wave vibration to the first liquid. A part of a liquid conduit is provided in an ultrasonic wave liquid tank which has an ultrasonic wave oscillator and is filled with an ultrasonic wave propagating liquid. An absolute pressure of 1.3 Kg/cm2 or higher is maintained applied inside the liquid conduit. Ultrasonic wave vibration generated by the ultrasonic wave oscillator is imparted to the first liquid which is continuously delivered without causing a vapor-liquid interface in the liquid pipe, to dissolve the bubbles in the first liquid and to prevent deposition of bubbles under the atmospheric pressure.
