Title: Multilayer magnetoresistive sensor
Inventor: COFFEY KEVIN R
IPC: H01L43/10
Filed: 1994-10-31
Abstract: A magnetoresistive read sensor incorporates a multilayer sensing element formed of one or more magnetoresistive elements in a planar array, each magnetoresistive element having a multilayer structure of at least two ferromagnetic layers separated by a nonmagnetic layer. The ferromagnetic layers are coupled antiferromagnetically by magnetostatic coupling at opposing edges of the ferromagnetic layers. A bias layer separated from the magnetoresistive sensing element by a spacer layer provides a magnetic field to bias the magnetoresistivesensing element at a desired non-signal point for linear response. The magnetoresistive sensing element is formed by alternatively depositing layers offerromagnetic material and layers of nonmagnetic material on a substrate and then patterning the resulting structure using photolithographic techniques to provide a planar array of magnetoresistive elements. A conductive layer is deposited over the array filling in the spaces separating the magnetoresistive elements to provide electrical conductivity between the elements in the plane of the structure.

Patent CA-2145145-A1 (CA)
Title: Ram-type blowout preventer
Inventor: OLSON RICHARD A
IPC: E21B33/06
Filed: 1995-03-21
Abstract: An actuator for a ram-type blowout preventer used either with a shear ram blowout preventer or a pipe ram blowout preventer. The actuator includes a pressure-responsive cylinder having an operating piston disposed therewithin. The piston includes a shaft for transmitting relative motion to the ram in the blowout preventer. A reversible annular member is disposed around the periphery of the piston to provide a variable pressure force in a shear ram blowout preventer and to limit the stroke of the piston in a pipe ram blowout preventer. The annular member includes a pair of annular flanges extending radially inward to form a channel therebetween. The channel receives the periphery of the piston which is moveable within the channel between the flanges. In a shear ram blowout preventer, the annular member increases the annular pressure area of the piston during the shearing stroke to increase the pressure force on the rams and their seals during the shearing of the pipe. After the pipe has been sheared, the annular member bottoms on the end of the cylinder allowing the piston to continue to travel in the channel such that the reduced annular pressure area of the piston reduces the pressure force on the rams and their seals during the sealing stroke to seal the bore after the pipe has been sheared. The reversible annular member is reversed on the piston in a pipe ram blowout preventer. In the reverse position, the annular member increases the annular pressure area during the sealing stroke until the annular member bottoms on the end of the cylinder. The piston is then allowed to continue to travel a short distance within the channel until the piston engages the other annular flange of the annular member thereby reducing the stroke of the piston. In the shear ram blowout preventer, the piston is allowed to engage the bottom of the cylinder for a full stroke equal to the axial length of the cylinder while the piston bottoms out on the annular flange of the annular member in a pipe ram blowout preventer to reduce the stroke of the operating piston within the cylinder.

The first and second grooves each have a bottom face provided with a generally rectangular protuberance situated centrally of the groove while the first peg is formed of two spaced apart peg elements generally half-moon shaped in cross section. To removably install the load support member on the dorsal member, the first peg is inserted in the first or second groove by sliding the rectangular protuberance in the passage between the two peg elements. The load support member is then pivoted about the first peg until the second peg is inserted in the third groove.

Patent CA-2147336-A1 (CA)
Inventor: KIMURA YASUYUKI
IPC: G11B7/0033
Filed: 1995-04-19
Abstract: For recording or reproduction of  information,  the optical beam is moved relative to the recording medium along the  longitudinal  direction  of  a  certain  track.    When accessing another track, the relative  movement of the light beam  along  the  longitudinal  direction of  the  track  is decelerated, and during this deceleration, the light beam is started to move in the direction transverse to the tracks toward the desired track.  Thus, it is not necessary to wait for such time when the relative  movement of the light beam along the longitudinal direction of the track has been completely stopped, and hence the necessary accessing time can substantially be reduced.  If control is made to cause a decelerating rate of the relative  movement to decrease continuously gradually or stepwise from a relatively high decelerating rate to a relatively low rate and the light beam is caused to start relatively moving toward the desired track while the relative  movement is at the relatively low decelerating rate,  it is allowed to effectively suppress occurrence of unwanted  mechanical vibration due to abrupt deceleration of the relative  movement.

Filed: 1994-01-06
Abstract: An insert (1) for positioning in a con-tainer of beverage such as beer which is to be sealed under pressure. In use, the insert is filled with gas and/or beverage which is released from the insert in order to gen-erate foam in the beverage when the con-tainer is opened. The insert is formed from two mouldings (2, 12) which snap together. One of the mouldings (12) is deformable between a convex and a concave configu-ration. Apertures (10a, 14) are provided in each moulding so that when the moulding (12) is in its convex configuration, commu-nication is provided via the apertures into the insert. When the moulding (12) is in its concave configuration this communica-tion is substantially restricted, leaving only a small passage (14a). In use, a jet of gas is released from the insert via this aperture in order to cause the production of foam in the beverage. The invention also extends to a method of filling the insert (1) with nitrogen gas.

Abstract: A five valve manifold for use with a pressure sensing apparatus is disclosed. It has an integral body having a first face, a second face, parallel with the first face. A peripheral wall section, spans the distance between the first and second face sections. The distance is smaller than at least one of the width and the length of the second face section. A passage system within said body and includes a pluralaty of mutually intercommunicating passages extending from one said face to the other.
