摘要： A gripping device for an endoscope insertion tube utilizing first and second arms that are hingedly attached to one another. Each arm includes an opening to accommodate the insertion tube of an endoscope such that the endoscope insertion tube spans both arms. First and second jaws are associated with first and second arms and are positioned in opposition to one another. The movement of the arms toward one another causes the jaws to engage the insertion tube which is guided through the arms by the apertures found in the arms.

摘要： Systems, methods and devices are provided for the automated centrifugal processing of samples. In some embodiments, an integrated fluidic processing cartridge is provided, in which a centrifugation chamber is fluidically interfaced, through a lateral surface thereof, with a microfluidic device, and wherein the integrated fluidic processing cartridge is configured to be inserted into a centrifuge for centrifugation. A cartridge interfacing assembly may be employed to interface with the integrated fluidic processing cartridge for performing various fluidic processing steps, such as controlling the flow of fluids into and out of the centrifugation chamber, and controlling the flow of fluids into the microfluidic device, and optionally for the further fluidic processing of fluids extracted to the micro-fluidic device. The integrated fluidic processing cartridge may include a supernatant chamber the extraction of a supernatant thereto, and a diluent chamber for diluting a suspension collected in the centrifugation chamber.

摘要： A valve arrangement for controlling gas flow. A gas block includes a gas inlet, a gas outlet, and a gas cavity fluidly connecting the gas inlet to the gas outlet. A diaphragm is configured for controlling gas flow between the gas inlet and the gas outlet. An actuator is configured to vary the position of the diaphragm so as to control the gas flow. The actuator comprises a tubular housing; a plunger positioned inside the housing and having an actuating extension extending outside of the housing and coupled to the diaphragm, the plunger configured to be slidable inside the housing; a piezoelectric body positioned inside the plunger; and a pre-loader applying force to the plunger so as to press the plunger against the piezoelectric body.

摘要： A diaphragm valve and a flow rate control device for a semiconductor manufacturing apparatus are configured so as to allow an increase of a valve flow rate while avoiding an increase in size of the valve. The diaphragm valve includes a diaphragm with an outer periphery being pressed and a valve seat part in a valve chamber of a body having an inflow path and an outflow path, with the diaphragm being configured to open and close the valve chamber by an ascending/descending motion of a stem. The diaphragm has a substantially-flat cross sectional form having a substantially-planar center region and a boundary region. The boundary region is on an outer peripheral side of the center region and has a radius of curvature smaller than that of the center region, and the boundary region is positioned near an outer peripheral side of the valve seat part.

摘要： An electronic cigarette includes a power supply device, a sensing unit, an atomizer, a liquid storage structure and a fluid transportation device. The atomizer includes an electric heater and a liquid conduit. The liquid conduit has an input port at one end and plural perforations at the other end, and the electric heater is disposed around the liquid conduit. The liquid storage structure includes a passageway and a liquid container. A cigarette liquid is stored in the liquid container. The fluid transportation device includes an input channel and an output channel. The input channel is in communication with the liquid container. The output channel is in communication with the liquid conduit of the atomizer. The cigarette liquid is transferred to the atomizer at a certain amount. Consequently, an atomized vapor is generated.

摘要： A pinch valve has an upper casing support the entire pinch assembly and the lower casing. In a particular embodiment, a quarter-turn actuator is deployed and the sleeve may be removed without moving the actuator. The body may be open or closed to retain an external air pressure used to help close the sleeve and reduce actuator forces.

摘要： A gas control device includes a pump, a valve, a cuff, and a controller. The valve includes a first plate having a first vent hole and a first vent hole, a channel forming plate having an exhaust hole and an exhaust channel, a second plate having a second vent hole, and an edge separation plate. A manchette rubber tube in the cuff is joined to the periphery of the second vent hole in the second plate by an adhesive, and thus the valve is connected to the cuff. The exhaust hole is opened to the atmosphere. The pump includes a pump housing having a discharge hole and a discharge hole. The upper surface of the pump housing is joined to the bottom surface of the edge separation plate.

摘要： A gas delivery system for a substrate processing system includes first and second valves, a first gas channel, and a cylinder. The first valve includes a first inlet and a first outlet. The first outlet is in fluid communication with a processing chamber of the substrate processing system. The second valve includes a second inlet and a second outlet. The cylinder defines a second gas channel having a first end and a second end. The cylinder is at least partially disposed within the first gas channel such that the cylinder and the first gas channel collectively define a flow channel. The flow channel is in fluid communication with the first end of the second gas channel and with the first inlet. A third gas channel is in fluid communication with the second end of the second gas channel and with the second inlet.
