摘要： PROBLEM TO BE SOLVED: To provide a bubble production device smaller in size than a conventional one and capable of producing a foamy liquid containing a smaller percentage of large-diameter foams and having high uniformity.SOLUTION: A member, which is provided with a gas discharge port which discharges gas from the same through a gas passage into a liquid in a gas and liquid mixing unit, has a surface lyophilic to a foamy liquid. Thus, when the gas is discharged from the gas discharge port, a bubble begins to be produced in a fixing solution and a constricted portion at a lower section of the bubble is produced as the bubble grows. However, a contact angle between the surface of the bubble and the surface of the member provided with the gas discharge port remains small because the surface of the member provided with the gas discharge port is lyophilic to the foamy liquid. For this reason, the constricted portion of the bubble is not extended and the constricted portion is cut off before the bubble grows large, thereby the foamy liquid with a small bubble diameter is produced.
摘要翻译：要解决的问题：提供一种泡罩制造装置，其尺寸比常规尺寸小，能够制造含有较小百分比的大直径泡沫并具有高均匀性的泡沫液体。解决方案：具有气体排出口的构件具有与气体和液体混合单元中的液体一起通过气体通道排出气体的气体排出口，其具有与泡沫液体亲液性的表面。因此，当气体从气体排出口排出时，在定影液中开始产生气泡，并且在气泡生长时产生气泡下部的收缩部分。然而，气泡的表面与设置有气体排出口的构件的表面之间的接触角保持较小，因为设置有排气口的构件的表面与泡沫液体是亲液性的。因此，在气泡生长较大之前，气泡的收缩部分不会延伸并且收缩部分被切断，从而产生具有小气泡直径的泡沫状液体。版权所有（C）2012，JPO＆INPIT
