20150362391Pressure Sensor, and Mass Flow Meter and Mass Flow Controller Using the Same - There is provided a pressure sensor which includes: a diaphragm having an inside surface facing to a fluid-tight space, the diaphragm including a diaphragm film that is part of the inside surface and deformable in response to a pressure application, and a diaphragm film support that is part of the inside surface and constitutes a periphery of the diaphragm film; a strain sensor bonded to the inside surface so as to lie partially on the periphery and having plural strain gauges thereon; and a depression formed on the inside surface, when defining an x-direction oriented from center of the inside surface to a position bonded of the strain sensor and a y-direction perpendicular to the x-direction on the inside surface, the depression extending a certain length in the y-direction, the depression being adjacent to or a certain distance apart from an edge of the strain sensor in the y-direction.12-17-2015
20160048138Compact Inverted Pressure Regulator for Dispensing a Gas - An inverted gas pressure regulator includes at least one inlet duct for admitting a gas at a high pressure, at least one outlet duct for letting out this gas at a low pressure from a downstream expansion chamber. A mobile regulator piece against one side of which the low pressure presses and against the other side of which a spring element presses that is able to close off the high pressure gas inlet. Upstream and downstream connectors are able to connect and incorporate the pressure regulator to/into any gas circuit. Inlet and outlet ducts are each situated in the upstream and downstream connectors respectively, and these two connectors, which are positioned coaxially, are able to connect the pressure regulator in-line to said circuit.02-18-2016
20160076189INTEGRATION APPARATUS FOR WATER VALVE FOR A WASHING MACHINE AND METHOD OF MANUFACTURING THE SAME - An integration apparatus for a water valve for a washing machine includes: a depressurizing valve unit installed in a valve head and operable for maintaining a hydraulic pressure of a feed water to less than a preset hydraulic pressure limit; and a filter unit disposed in front of the depressurizing valve unit.03-17-2016
20160076683Coupling Assembly for a Pipe and Valve Assembly Comprising the Same - A valve assembly comprising: a body having a threaded tubular connector sized and shaped to receive a pipe having a first fluid line; a primary passageway defined through the body and the tubular connector for connection to the first fluid line; a valve disposed in the primary passageway; and a coupling assembly for sealingly connecting the pipe to the body, the coupling assembly including: an annular compression member adapted to be disposed around the pipe, the annular compression member threadingly engaging the tubular connector such that rotation of the compression member selectively moves the annular compression member axially towards and away from the body; and an O-ring seal adapted to be disposed concentrically around the pipe between the annular compression member and the body, the O-ring being compressed when the annular compression member is moved towards the body to create a seal between the pipe and the body.03-17-2016
20160126517CLOSURE PLUG ASSEMBLY, CASE AND RECHARGEABLE BATTERY - The invention relates to a sealing plug arrangement (05-05-2016
20160146359Temporary Elastomeric Functional Barrier Membrane and Method of Manufacture - A fluid check valve incorporating a temporary elastomeric functional barrier membrane, the check valve having a sealing member comprising a first elastomer and a barrier membrane comprising a second elastomer, different from the first elastomer, disposed directly upon the surface of the sealing member so as to form a continuous layer over at least a seal opening of the sealing member. The barrier membrane may include a photoinitiator and coagent which aids in the ultraviolet (UV) curing of the second elastomer after application upon the first. The barrier membrane may applied as a solution of monomers, photoinitiator, and optional coagent, the solvent evaporated, and the deposited solutes exposed to ultraviolet so as to form the barrier membrane material.05-26-2016

20160376913PRESSURE LIMITERS - A bleed valve system includes a flow path defined between a system inlet and a system outlet. A pressure control mechanism is defined in the flow path downstream from the system inlet to selectively block fluid flow in the flow path. A pressure limiter is defined in the flow path downstream from the system inlet and upstream from the pressure control mechanism to block the flow path when the pressure at the system inlet is greater than the pressure capacity of the pressure control mechanism.12-29-2016
