| 20080210017 | Orifice Member, and Differential-Pressure Flow Meter and Flow-Regulating Apparatus Using the Same - Provided are an orifice member, and a differential-pressure flow meter and a flow-regulating device using the orifice member, that allow purging to be carried out easily when changing the fluid to be circulated, that are less likely to cause contamination and leaching of impurities to the circulated fluid, and that can be easily produced. The flow-regulating device includes a first pressure-measuring device (object to be connected to) that is connected to one end of the orifice member, and a second pressure-measuring device (object to be connected to) that is connected to the other end of the orifice member, and a flow-regulating valve that is connected to the downstream side of the differential-pressure flow meter, which includes the above-mentioned units. In the orifice member, a tube portion, one end of which is connected to the first pressure-measuring device and other end of which is connected to the second pressure-measuring device and whose internal part forms a channel connecting the first and second pressure-measuring devices, and an orifice provided inside the tube portion are integrated. | 09-04-2008 |
| 20080210324 | Damper - A damper that has chemical resistance, that can be used under a high-pressure environment, and that can remove pressure pulsations is provided. This damper includes a fluid chamber into and out of which a fluid flows, a diaphragm defining at least one surface of the fluid chamber, and a separate chamber adjacent to the fluid chamber in a fluid-tight manner, with the diaphragm disposed therebetween. The diaphragm includes a first film having chemical resistance and a second film having pressure resistance. | 09-04-2008 |
| 20090020176 | JOINT FOR FLUID CONTAINER - A joint for duplex storage type fluid container that can attain secure fitting of a liquid discharge tube and can attain easy, secure connection of a passage for fluid emission disposed in a dispenser to the liquid discharge tube. There is provided a joint for fluid container comprising flexible bag ( | 01-22-2009 |
| 20090026059 | PRESSURE SWITCH - A compact pressure switch that causes little error in the operating point of the switch and that has resistance to dust, water, and chemical solutions is provided. The pressure switch includes a housing ( | 01-29-2009 |
| 20090072173 | Flow control valve - An object is to provide a flow control valve that is capable of reducing or eliminating backlash generated between a male threaded portion and a female threaded portion engaged with the male threaded portion and preventing or eliminating hysteresis in the flow level. The flow control valve includes a body having a fluid inlet and a fluid outlet, a cover attachable to the body, a motor disposed in a space defined by the body and the cover, a valving element connected to a rotary shaft of the motor with a screw member, and an urging member that urges the valving element toward the motor side or toward the side opposite to the motor. | 03-19-2009 |
| 20090078038 | FLOW METER AND FLOW-REGULATING SYSTEM USING THE SAME - Provided are a flow meter and a flow-rate control system using the same that is capable of measuring a flow rate in a minute flow-rate region with excellent measurement accuracy by preventing or suppressing the generation of bubbles and in which accumulation of the fluid and the bubbles is less likely to occur. The flow meter is for measuring a minute flow rate of a fluid flowing through a fluid channel whose outlet environment is set to constant pressure, the flow meter including a flow-rate measurement conduit portion having a predetermined length connected to an outlet-side end of the fluid channel | 03-26-2009 |
| 20090101667 | Connector Structure - A connector structure that can minimize the amount of liquid remaining in a container is provided. In a connector structure that is attached to an opening | 04-23-2009 |
