Publication number: 20100101660Abstract: A channel switching system includes two microvalves i.e. a first valve (stopper valve) and a second valve (water retaining valve). The first valve is openable and closable, and the second valve is operable to block fluid flow by a surface tension force. Changing the first valve from an open state to a close state enables to switch the system from a condition that the fluid flows through the channel where the first valve is mounted by blocking the flow at the second valve by the surface tension force to a condition that the fluid flows through the channel where the second valve is mounted by releasing the system from the condition that the flow is blocked at the second valve by the surface tension force.Type: ApplicationFiled: February 21, 2008Publication date: April 29, 2010Applicant: Konica Minolta Holdings, Inc.Inventors: Ken Kitamura, Toshihito Kido, Shinji Harada, Kenichi Miyata, Yasuhiro Sando
