摘要:
A compressor includes a rotor platform; a rotor blade; and a casing having an inner surface surrounding the tip and spaced radially outwardly from the tip to define a gap. A secondary air flow system includes a bleed inlet configured to remove secondary air flow from the primary air flow; an injection opening disposed in the inner surface of the casing upstream of the bleed inlet; an accessory conduit; and a plenum fluidly coupled to the bleed inlet, the injection opening, and the accessory conduit. The bleed inlet and plenum at least partially define a secondary air flow path such that a first portion of the secondary air flow is directed in through the bleed inlet, through the plenum, and out through the injection opening and a second portion of the secondary air flow is directed in through the bleed inlet, through the plenum, and out through the accessory conduit.

摘要:
A wire structure may have a loop of fishing line on each of four sides, with weights to lower the line, giving a loop on each side. These loops may be tied to a central fishing line, which a user may pull to close the loops. This may catch a crab if one is in the trap, allowing a user to bring the crab to a wharf or boat, for example. Releasing the fishing line may allow the weights to lower, which may open the loops and release the crab without the user needing to touch the trap near the crab, which may reduce the chance of being pinched by a crab claw.

A method of provisioning organization users in a multi-tenant database system includes receiving a request via a single sign-on protocol from an organization user to create a new multi-tenant database user account for access to the multi-tenant database system. The method retrieves rules that specify how to derive user permissions for access to the multi-tenant database system from stored user attributes of the organization user. The method continues with applying the rules to the stored user attributes to determine permissions for the users to access particular objects in the multi-tenant database system, and creating the new user account with the determined user permissions for access to the multi-tenant database system.

Disclosed is a polylactic acid composition with improved heat-resistance and improved impact-resistance. Specifically, in the disclosed polylactic acid composition, both impact strength and heat-resistance are improved by mixing 30 to 80 wt % of polyketone and 10 to 40 wt % of modified rubber. The disclosed polylactic acid composition does not only exhibit excellent in heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance, etc., but also has improved impact-resistance and improved heat resistance. Thus, it is possible to employ polylactic acid as a bioplastic in interior/exterior parts of a vehicle.

Disclosed herein is a joint structure of a core layer and a skin layer for manufacturing a partial foaming part having a polyurethane foam layer formed between the core layer and the skin layer. A recess is formed on the core layer corresponding to the joint of the core layer and the skin layer. The recess includes at the inside thereof a guiding wall for the skin layer and a pressing wall. A bent portion and a resilient supporting portion are formed in the end portion of the skin layer to be inserted inside the recess. The bent portion is bent upwardly so as to contact the guiding wall. The resilient supporting portion is resiliently supported underneath the pressing wall.

Disclosed is a ball grid array substrate having a window formed on a core material instead of a thin core material, and wherein a semiconductor chip is mounted thereon, thereby reducing the thickness of a package, and a method of fabricating the same. The ball grid array substrate comprises a first external layer which includes first circuit patterns, wire bonding pad patterns, and a window corresponding in size to a first chip mounted therein and wherein the chip is wire-bonded to the wire bonding pad patterns. A second external layer includes second circuit patterns, a portion corresponding in position to the window of the first external layer, and solder ball pad patterns. Second chips mounted on the solder ball pad patterns. An insulating layer interposed between the first and second external layers. The window is formed through the insulating layer at a position corresponding to the window of the first external layer.
