The present invention provides an integrated valve, push connection and push release components, and a valve mounting assembly for use on fluid, air or gas applications. The invention allows for the installation of the valve by sliding the valve over the supply tube / piping or pushing the tube / piping into the valve. Once connected, an o-ring seals the connection, a packing gland applies energy to the o-ring seal maintaining constant, even pressure across the seal, and a grip ring applies opposing energy to prevent the disconnection of the assembly. The quick connection assembly is retained by a retaining cap, which applies constant, positive force on the sealing surface.

The present invention provides a gas switching method for switching from gas supply source 101 to gas supply source 111, wherein the gas supply source 101 is switched to gas supply source 111 by opening a valve 114 in advance, setting a flow rate of MFC 112 to a flow rate used in the subsequent step, letting the gas supply source 111 to flow toward an exhaust means 5, and closing the valve 114 simultaneously when opening the valve 113, wherein a volume V1 of an area of a gas pipe 115 surrounded by the valve 113, the valve 114 and the MFC 112 is set sufficiently smaller than a volume Vo from the shower plate to the valve 113 including a gas reservoir 10 and a processing gas line 8. The present arrangement enables to prevent the occurrence of pressure undershoot and to solve the problem of discharge instability.

A safety panel is attachable to the grip of a handgun that stores rounds in the grip and that has at least one opening in the frame of the grip through which hot gases and shrapnel may pass in a blowout. The safety panel is a plate that completely covers the openings and that has no apertures through it in a portion that is over an opening. The plate may have screw holes through it for attaching it to the frame. It also may have indentations in its periphery for an ambidextrous thumb safety, a mainspring housing pin, and a magazine release clearance. The safety panel is attached to the grip of the gun by removing the grip cover, inserting the safety panel in between the frame and the grip cover, and re-fastening the grip cover to the frame.

The present application provides a shoulder strap applicable to a baby carrier, comprising: a strap body having a top end and a bottom end and two sides; and at least one of a decompression expansion member extending outwardly from at least one of the two sides of the strap body, being as long as the strap body, and connected to the top and bottom ends of the strap body, respectively, wherein the decompression extension member has a first extended flap medially extending toward the other one of the two sides of the strap body and a second extended flap extending in a reverse direction to the inner side of the first extended flap, and having an outer side.

A lithium secondary battery including: an inner electrode member having electrode plates (cathode plate and anode plate) of a metal foil as a constituting element, and being formed by winding or laminating electrode plates; and a battery case for housing the inner electrode member. A gas release channel capable of releasing a gas to the outside of the battery case is formed by deformation of the inner electrode member by a function of a raised inner pressure when the inner pressure of the battery case rises to a predetermined pressure or more due to the gas generated inside the inner electrode member. The lithium secondary battery can smoothly release the gas generated inside the inner electrode member without being retained therein before the gas reaches a pressure releasing mechanism; thus, it is superior in safety and has a high energy density.

The present invention relates generally to a device for supporting the foot and more particularly to a device for relieving pressure from specific areas of the foot, and for relaxing and shortening the musculatures of the foot by raising the arch. Through specific shapes and materials, the design intends to aid in alignment, add comfort, and prevent and relieve many foot problems and other lower extremity ailments. The device is uniquely designed to sit in the midfoot region of an article of footwear to relieve pressure from the heel and forefoot, redistribute pressure more evenly across the foot, and support the foot arches. The device may be constructed from flexible material which allows the orthotic to form to the shape of the shoe it is placed in. The medial wing portion of the orthotic device may utilize the medial wall of a shoe to increase arch support.

A hermetically sealed compressor including a pressure release device. In one exemplary embodiment, the pressure release device includes a flange portion and a rupture portion. The flange portion is positioned against and secured to the inner surface of the housing of a hermetically sealed compressor. In this embodiment, the rupture portion extends at least partially within a vent aperture extending through the compressor housing. When the interior pressure of the housing exceeds a predetermined limit, the rupture portion of the pressure release device opens allowing the fluid within the compressor housing to escape. In another exemplary embodiment, the pressure release device further includes a connecting portion positioned between the flange portion and the rupture portion. In one exemplary embodiment, the connecting portion forms an S-curve.

A safety device of a battery including a pressure releasing unit provided at a cell and the battery, in which the pressure releasing unit is configured to release an internal pressure within the cell when the internal pressure of the cell exceeds a predetermined set pressure. Also included is a space member covering the pressure releasing unit and configured to form an empty space around the pressure releasing unit such that when the internal pressure of the cell exceeds the predetermined set pressure, the released internal pressure is released into the empty space formed by the space member.
