A method for improving purging of fuel vapors from a boosted engine is presented. In one embodiment, the method increases the efficiency of a venturi that supplies vacuum to purge fuel vapors from a vapor storage canister.

Assemblies, systems, and methods convey fluid from an internal wound site or body cavity by applying negative pressure from a source outside the internal wound site or body cavity through a wound drain assembly that is placed directly inside the internal wound site or body cavity.

A woven or knitted fabric, formed from two types of yarns different in self-elongating property upon absorbing water and capable of facilitating the air-permeability when wetted with water, is constituted so that a ratio A / B of a mean length A of yarns (1) having a high water-absorbing, self-elongating property to a mean length B of yarns (2) arranged in the same direction as that of the yarn (1) and having a lower water-absorbing, self-elongating property than that of the yarn (1) is adjusted to 0.9 or less.

A rear projector (1) has a closed space (530) including an inside of an upper cabinet (12) and an electric optical device (44), where the electric optical device (44), a sirocco fan (541) located below the electric optical device (44), a duct (542) covering the upper side of the electric optical device (44) and a heat sink (543) attached to the upper cabinet (12) are disposed and an upper cabinet cooling system (600) that cools the interior of the closed space (530) in a circulative manner is provided in the closed space (530), thereby preventing invasion of duct etc. and providing high-quality image.

A locking tree cap for use on a subsea tree. The tree cap may be installed and retrieved using a remote operated vehicle. The tree cap may include deflectable collet fingers that lock the tree cap to a tree spool. The deflectable collet fingers may be adapted, such as with enlarged heads, to extend into recesses of the tree spool when the tree cap has been landed on the tree spool. The tree cap may be locked onto a tree spool before energizing sealing members within the bores of the subsea tree, thereby protecting the sealing members from damage during the installation of the tree cap onto the tree spool. The tree cap may include soft landing means such as a plastic cap, on the end of stabs to protect the sealing members as the tree cap is landed. The tree cap may include a secondary locking mechanism used to further secure the tree cap to the tree spool.

To reduce an opening area of a wall through hole in a paper sheet handling device having a paper sheet handling part installed separately from a transaction port part via a wall. A bill handling device is provided with a deposit / payment port unit 10, to / from which a bill for transaction is inserted / discharged, and a bill handling unit 101 connected to the deposit / payment unit via a conveying path for determining validity of the bill and performing bill charge / discharge processing. In the bill handling device, the conveying passage for the deposit / payment port unit and that for the bill handling unit arranged separately via a clearance are connected together by means of a connection conveying path unit 60. When the bill handling unit is mounted on the inside face side of the wall and only the deposit / payment port unit is installed in the through hole of the wall, an opening area of the through hole in the wall can be reduced.

A woven or knitted fabric, formed from two types of yarns different in self-elongating property upon absorbing water and capable of facilitating the air-permeability when wetted with water, is constituted so that a ratio A / B of a mean length A of high water-absorbing, self-elongating yarns (1) to a mean length B of lower water-absorbing, self-elongating yarns (2) arranged in the same direction as that of the yarn (1) property is adjusted to 0.9 or less, the wetted fabric exhibits a change in roughness of 5% or more.
