A turbine engine annular combustion chamber includes inner and outer longitudinal walls connected upstream by a transverse chamber bottom and including a single-piece cowling covering the chamber bottom. Each of the longitudinal walls is inserted between corresponding flanges of the chamber bottom and of the cowling. The longitudinal walls, the chamber bottom and the cowling are assembled together by a plurality of first fixings between the longitudinal walls and the chamber bottom alternating with a plurality of second fixings distinct from the first fixings between the longitudinal walls and the cowling.

A connector is provided with a rotatable toggle lever which is movable between a first position where the connector is fitted to a counterpart connector and a second position in which the connector is secured to the counterpart connector. The connector includes a housing and a lock member for locking the lever at the second position. The lock member has a body portion extending approximately parallel with one wall surface of the housing. The lock member has a locking engaging projection portion for engagement with the lever and, at one end of the body, has a releasing operation portion for releasing the engagement of the projection. A first connection portion connects the other end of the body portion to the one wall surface while second connection portions are arranged on both sides of the releasing operation portion to connect the one end of the body portion to the one wall surface. The lock member further includes cable protective projections projecting from the surfaces of the second connection portions in a direction away from the one wall surface. The lever includes a cross frame portion having a concave portion formed in a position located adjacent the releasing operation portion when the lever is in the second position.

A gas purge valve comprising a housing fitted with an inlet port being in flow communication with a liquid outlet port, and at least one gas outlet member, a gas flow barrier associated with the liquid outlet port, a float member displaceable within the housing between a first position adjacent the inlet port and a second position adjacent the gas outlet The at least one gas outlet is fitted with an inlet prohibiting valve, and is sealingly engageable by a flexible sealing member articulated to the float member. Buoyant displacement of the float member into the second position entails sealing of the at least one gas outlet by the flexible sealing member.

A chemical mechanical polishing apparatus includes a platen, a polishing pad affixed to a surface of the platen, and a polishing head configured to retain and rotate a wafer while pressing a surface of the rotating wafer against the polishing pad. A first portion of the polishing pad that engages the polishing head proximate the edge of the wafer provides less rigidity than a second portion of the polishing pad that engages a portion of the surface of the wafer. For example, the polishing pad and / or the platen may have a recess or other cushioning structure positioned proximate a locus of movement of a portion of the polishing head that supports the edge of the wafer.

An end seal for a fluid chamber which supplies fluid to a roll, includes a generally parallelepiped compressible member having first and second opposite sides and including a first end section having a first inclined planar upper surface, a second end section having a second inclined planar upper surface, and a central section which connects together the first and second end sections, the central section having an arcuate upper surface for receiving the roll, the arcuate upper surface connected to the first and second inclined planar upper surfaces at respective apices; and at least one pressure relieving recess positioned in the compressible member at a position below at least one apex, each pressure relieving recess extending through one side of the compressible member and terminating short of the opposite side of the compressible member so as to define a membrane of the compressible member thereat.

A glass film laminate includes a glass film and a supporting glass. The glass film and the supporting glass have surfaces in contact with each other, and each of the surfaces has a surface roughness Ra of 2.0 nm or less.

A method of manufacturing a footwear sole component is provided including projecting elongated pins into a mold cavity in the shape of the footwear sole component and partially filled with an expandable material including multiple unexpanded beads, and introducing steam into the cavity through ports defined by one or more cavity walls and through the pins in an internal region of the expandable material, to expand both exterior beads and interior beads in the internal region a predetermined amount. With the elongated pins, the interior beads can be expanded more, less and / or the same amount as exterior beads to provide particular physical characteristics to the component. For example, the interior beads can be fully expanded to a similar density as exterior beads, or expanded less to provide more density and rigidity in the internal region, or expanded more to provide less density and rigidity in the internal region.

A joint structure for an independent system designed to improve the maintenance performance of a rear wheel suspension. Rear wheel axles extend leftward and rearward from a final case supported by the rear portion of a body frame to independently suspend respective left and right rear wheels. The respective rear wheel axles are coupled to left-hand and right-hand joints on the left and right sides, respectively, of the final case. A driven sprocket engaging with a chain is attached to the left-hand joint and a separate holder is detachably attached to the front of the final case. A joint-part shaft of the right-hand joint is supported by the final case via a bearing and also a brake disk is attached thereto. A male-shaped joint-part shaft integrally extending from the left-hand joint is fitted into the female-shaped joint-part shaft for integrally rotatable coupling.
