摘要： The invention relates to a miniaturized fluid flow switch which enables a directed deflection or deviation of a fluidic test current injected into a fluidic carrier current. The aim of the invention it to provide a fluid flow switch which does not require any moveable parts and with which no restricting preconditions exist with regard to the fluid media to be used. To this end, the inventive switch is comprised of at least two carrier current channels (11, 12) and of a test current channel (2) which, together, open into a distribution chamber (3) to which at least two discharge channels (41, 42) connect. The carrier current channels (11, 12) are connected to a common inlet (10), and at least the carrier current channels (11, 12) are respectively placed, in particle sections, in close thermal contact with controllable heating devices (5). Said heating devices are attached such that they are thermally insulated from the remaining components, and in the area of the heating devices (5), the carrier current channels (11, 12) comprise a channel cross section (111, 121) which is narrower than the other carrier current channel cross section.

摘要： PROBLEM TO BE SOLVED: To easily control a flow of a fluid in a micro-system without using complicated valve structure. SOLUTION: A substance having a property of sol-gel transition by stimulation is added to the fluid flowing in a micro-passage of the micro-system, the stimulation is applied to a desirable portion on the micro-passage, and the fluid is thereby gelled to control the flow.

摘要： PURPOSE:To easily select a single straight jet, a single deflected jet, two differently-oriented divided deflected jets or three differently-oriented jets, by providing two independently-slidable deflecting portions at a fluid outlet port and sliding the portions to various positions. CONSTITUTION:A casing 11 is provided with holes 14a, 14b into which metal shafts 4a, 4b are slidably inserted. Deflecting portions 2a, 2b are secured on the tips of the shafts 4a, 4b and operating knobs 3a, 3b are seucred on their butts. The casing 11 is so shaped that an inlet part 16 has both side walls 15 having steps 13 and extending to both the curved guide walls 12 of an outlet part 5. The deflecting portions 2a, 2b are provided with flat sides 21 parallel with the side walls 15 and are also provided with curved sides 22 which can be brought into conatct with the guide walls 12. The deflecting portions 2a, 2b are moved separately or jointly to various positions to define different outlet passages among the casing 1 and the deflecting portions.
