A method for forming sidewall spacers on a gate stack by depositing one or more layers of silicon containing materials using PECVD process(es) on a gate structure to produce a spacer having an overall k value of about 3.0 to about 5.0. The silicon containing materials may be silicon carbide, oxygen doped silicon carbide, nitrogen doped silicon carbide, carbon doped silicon nitride, nitrogen doped silicon oxycarbide, or combinations thereof. The deposition is performed in a plasma enhanced chemical vapor deposition chamber and the deposition temperature is less than 450° C. The sidewall spacers so produced provide good capacity resistance, as well as excellent structural stability and hermeticity.

An improved gelatinous elastomer is disclosed which uses an A-B-A triblock copolymer having a molecular weight in the range of 125,000 to 175,000, or about 150,000, and a plasticizer.

A collapsible chair. The chair includes a chair frame having two spaced leg structures and a top ring mounted to and supported on the leg structures. Each leg structure includes a top bar and front and rear side bars depending from the top bar to form a substantially U-shape. The top ring is fixed to the top bars. The front and rear side bars are rotatable with respect to the top bar for collapsing the chair frame. Front and rear ground members are respectively connected between the front side bars and the rear side bars. The ground members have a U-shaped configuration having a bottom section positionable on a fixture and first and second side sections extending from opposite ends of the bottom section. The first side section is rotatably fit over a lower end of a first one of the front side bars or the rear side bars of the leg structures and the second side section is removably fit over a second one of the front side bars or the rear side bar of the leg structures.

This invention relates to a light-weight foldable chair for leisure with seat and backrest loop capable to be folded once, which can be used in households, outdoors, in a courtyard, in a park and at the beach.

The present invention provides a convertible furniture piece generally including a base, a first quick-release locking mechanism, a first cushion member and a first support bracket. The first quick-release locking mechanism is attached to the base. The first cushion member has a first surface and a second surface generally perpendicular to each other. The first surface is supported on the base. The first support bracket is removably attached to the base by the first quick-release locking mechanism. The first support bracket engages the second surface of the first cushion member to solely provide lateral support thereto.

An air-pressure applying assembly for a seat, having an occupant holding portion, for selectively applying a desired pressure to the body of a seat occupant. This assembly includes an air-bag assembly, an air-pressure source, an inlet-conduit assembly, an exhaust valve assembly, and a control assembly. The air-bag assembly is removably mountable to the seat occupant holding portion. The inlet-conduit assembly is in fluid communication at one end to the air-pressure source and at another to the air-bag assembly. The exhaust valve assembly is in fluid communication at one end to the inlet conduit assembly and has an air-outlet at the other end. A control assembly is linked to the air pressure source and to the exhaust valve assembly. The control assembly is so configured as to selectively signal the air-pressure source to inflate the air bag assembly so as to apply the desired pressure to the body of the seat occupant and as to selectively signal the exhaust valve assembly to release air from the air-bag assembly.

A chair includes a first leg, a second leg pivotally mounted on the first leg, and a seat frame mounted on the first leg and the second leg by a plurality of detachable connecting members. Thus, the first leg, the second leg and the seat frame are assembled and disassembled easily and conveniently, thereby facilitating the user mounting the chair. In addition, the seat frame is combined with the first leg and the second leg by the connecting members, thereby simplifying the working procedure.

A backpack chair which allows the user to carry a chair on their back while still having the packing ability of a backpack. Embodiments of the backpack chair include a collapsible chair frame which opens into a chair and collapses into a backpack frame. A seat panel attached to the collapsible chair frame provides support for the user when the frame is opened into a chair. A pack container is attached to the seat panel and a flap is also attached in order to close the pack container and provide shade for the user when the collapsible chair frame is being used as a chair. The collapsible chair frame is also configured to form a stand for the backpack in order to provide ease of packing and unpacking the pack container. Shoulder straps are attached directly opposite the pack container on the collapsed collapsible chair frame.

A folding lounge chair has a seat frame, including a front leg and a rear leg crossing each other and hinged to the seat frame. At the crossing of the front leg and the rear leg, a hinge plate having a guide groove is fixed to the rear leg. At two ends of the guide groove are, respectively, upper and lower arrest units. The lower arrest unit is curved upwards. At one end of the lower arrest unit is provided a projected retaining part. One end of a bolt is fixed onto the rear leg, the other end running through the guide groove of the hinge plate, permitting the bolt to glide up and down along the guide groove. Besides allowing the lounge chair to retain a simplified construction, when the legs are unfolded, the bolt will not glide into the lower arrest unit and will be arrested by the projected retaining part. Therefore, the legs will not easily fold up. By lightly patting on the rear leg, the bolt will jump away from the projected retaining part and escape out of the lower arrest unit, and allow the legs to be folded up. Thereby, the legs of the chair can be easily folded or unfolded by simple operation.
