摘要： Provided is an UFB generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. To this end, the ultrafine bubble generating apparatus includes a pre-processing unit that performs predetermined pre-processing on a liquid W and a generating unit that generates ultrafine bubbles in the liquid on which the pre-processing is performed. The generating unit generates the ultrafine bubbles by causing a heating element, which is provided in the liquid on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element.

摘要： An ultrafine bubble generating apparatus generates thermal-ultrafine bubbles by bringing a liquid into film boiling while using a heater provided to a substrate. The ultrafine bubble generating apparatus includes a control unit which inputs energy to the heater such that a value of a ratio of energy to be inputted to the heater relative to energy with which the heater generates film boiling falls below 1.17 under a condition that the energy to be inputted to the heater is larger than the energy with which the heater generates film boiling.

摘要： A platen disposed at a position at which the platen faces a printing head includes a contact portion that comes into contact with a recording medium, a non-contact portion that does not come into contact with the recording medium, and an ink receiving portion that receives ink ejected to beyond the recording medium. A recessed portion is formed between the ink receiving portion and the contact portion in the width direction of the recording medium so as to be lower than the contact portion in the vertical direction. A supply portion that supplies air to the recessed portion is formed upstream of the recessed portion in the conveyance direction of the recording medium.
