    摘要: Provided is a microchip having a liquid supply mechanism which can supply a solution in a micro flow path with a simple construction in which a drive source utilizing an osmotic pressure is arranged within the microchip and which controls the osmotic pressure by a control unit utilizing temperature or the like, whereby it is possible to effect drive control such as intermittent driving and continuous driving at a fixed velocity. The liquid supply mechanism using osmotic pressure includes an osmotic pump utilizing the osmotic pressure of a liquid filling chambers separated from each other by a semipermeable membrane, and a unit which varies the osmotic pressure by changing a condition of the solution in at least one of the chambers on the basis of a timing of a pumping operation.

    摘要: A pump includes an outer body; and a wall within said outer body. The outer body and the wall define a pumping cavity and an excitation cavity within the outer body. An excitable medium is contained within the excitation cavity. An excitation source is coupled to said excitable medium. This excitation source is operable to excite the excitable medium and create a standing wave therein. The standing wave acts through the wall to pump said fluid through said pumping cavity. Advantageously, the excitable medium is isolated from the pumped fluid by the wall.

    摘要: According to the present invention, a device body casing 17 has a liquid chamber 20a for temporarily storing a liquid to be transported by a pump, a gas chamber 20b, and an extendably and contractibly deformable pulsation suppression diaphragm 18, which separate them. The device body casing 17 having an aperture 27 so as to communicate with 20b, is detachably engaged with a valve case 23. The valve case 23 is provided with an automatic gas supply valve mechanism 33 and an automatic gas exhaust valve mechanism 34, which restrict the amount of the extendable and contractible deformation of the pulsation suppression diaphragm 18 within the predetermined range, so that a liquid pressure inside the liquid chamber 20a and an atmospheric pressure inside the gas chamber 20b may balance each other when the discharge pressure of the pump is fluctuated. The automatic gas exhaust valve mechanism 34 is provided with a gas exhaust port 32, a gas exhaust valve element 43, and a slider 48. The gas exhaust port 32 exhausts the gas from the gas chamber 20b to the outside, when the gas sealing pressure inside the gas chamber 20b is decreased. The gas exhaust valve element 43 usually makes the gas exhaust port 32 close. The slider 48 is operated so that the gas exhaust valve element 43 may usually make the gas exhaust port 32 open, when the pulsation suppression diaphragm 18 is moved in a direction of reducing the liquid chamber 20a so as to exceed the predetermined stroke. The gas exhaust valve element 43 is disposed on a tip of the gas exhaust valve rod 45. A rear end of the gas exhaust valve rod 45 is slidably inserted in the slider 48. The gas exhaust valve rod 45 is loosely inserted in a through hole 46 of the spring receiving member 47 fixed to the inside of the gas exhaust chamber 42 of the valve case 23. On the gas exhaust rod 45, a spring 49 for a closing state is disposed between the gas exhaust valve element 43 and the spring receiving member 47, and a spring 50 for an opening state is disposed between the spring receiving member 47 and the slider 48.

    摘要: A positive displacement pump includes a deformable hollow member for delivering a subject liquid by a cycle of contraction and restoration of its volume, a casing which contains the hollow member, and a pressurizing device for supplying and evacuating a hydraulic liquid in an annular space between the casing and the hollow member. The supplying of hydraulic fluid causes the contraction of the hollow member, and the evacuating of the hydraulic fluid causes the restoration (expansion) of the hollow member. A guide structure contacts and deforms the outer circumferential portions of the hollow member as the hollow member continues to expand to determine an initial contraction position of the hollow member. That is, a particular direction of contraction of the hollow member is set by the guide structure. Drive means periodically vary the circumferential position of the guide means relative to the hollow member to vary the initial contraction position of the hollow member. Consequently, stresses due to contraction and restoration are dispersed in the hollow member.
