The member 60 is generally conical and provides a large surface area over which the water cascades in a shallow stream from serration to serration enabling dogs and monkeys &c. to lick the member. The serrations 65 may be annular or may be arranged spirally or elliptically and the member may alternatively be frusto-conical or cylindrical.

충격 디바이스를 사용하여 점성 매체를 분사하기 위한 방법 및 장치

기판(23) 상으로 점성 매체를 분사하기 위한 이젝터(1)가 개시된다. 이젝터는 점성 매체를 수용하도록 적응되는 분사 챔버(2), 챔버에 연통되게 연결되는 노즐(3), 및 점성 매체가 노즐을 통해서 기판을 향해 분사되도록 챔버 내의 점성 매체의 체적에 충격을 가하도록 적응되는 충격 디바이스(4)를 포함한다. 이젝터는 분사될 점성 매체에 전단이 유도되도록 충격 디바이스의 길이 축을 중심으로 충격 디바이스를 회전시키도록 적응되는 회전 기구(5)를 더 포함할 수 있다. 대응하는 시스템 및 방법이 또한 개시되어 있다.
