Abstract: The invention provides a magnetoresistance element with a configuration such that a stable switching action is possible with a current flowing in response to the application of a unipolar electrical pulse, and a non-volatile semiconductor storage device using the magnetoresistance element. A magnetoresistance element 1-1 includes a magnetic tunnel junction portion 13 configured by sequentially stacking a perpendicularly magnetized first magnetic body 22, an insulation layer 21, and a perpendicularly magnetized second magnetic body 200. The second magnetic body 200 has a configuration wherein a ferromagnetic layer and a rare earth-transition metal alloy layer are stacked sequentially from the insulation layer 21 side interface.

Abstract: A system for selling wellhead production assets is provided. The system includes a bid request system that displays one or more bidders, such as approved oil refinery operators, and receives one or more bidder selections from the seller. A production posting system connected to the bid request system receives the bidder selections and provides lease data to the bidders selected by the seller, so as to allow the seller to obtain competing bids without alerting the bidders of the other competing bids.

Abstract: A check valve (10) including a valve disk (12), wherein the valve disk (12) is so arranged and configured as to be of a thickness sufficiently substantial to prevent the valve disk (12) from exhibiting a significant amount of flexure even under high reverse pressure, an upper housing portion (16) having an inlet aperture (18) formed therein, a lower housing portion (20) having an outlet portion (22) formed therein, the upper housing portion (16) being formed with a valve seat (24) which protrudes towards the lower housing portion (20) by a preselected distance, the inlet aperture (18) extending through the valve seat (24), a static seal ring (26) for installation between the upper (16) and lower (20) housing portions in sealing fashion, the static seal ring (26) being located circumferentially around and spaced away from the valve disk (12), and a support web (32) extending between the static seal ring (26) and the valve disk (12) for supporting the valve disk (12) from the static seal ring (26), the support
