A TMR sensor, a CPP GMR sensor and a CCP CPP GMR sensor all include a tri-layered free layer that is of the form CoFe/CoFeB/NiFe, where the atom percentage of Fe can vary between 5% and 90% and the atom percentage of B can vary between 5% and 30%. The sensors also include SyAP pinned layers which, in the case of the GMR sensors include at least one layer of CoFe laminated onto a thin layer of Cu. In the CCP CPP sensor, a layer of oxidized aluminum containing segregated particles of copper is formed between the spacer layer and the free layer. All three configurations exhibit extremely good values of coercivity, areal resistance, GMR ratio and magnetostriction.

A fan holder (1) includes a base (12) for supporting a fan (3) thereon and a pair of locking members (14) pivotally connected to the base. Each of the locking members includes a pivot shaft (142) and a handle (144) extending perpendicularly from the pivot shaft. The pivot shaft includes a pivot section (1422) and a pressing section (1426) offsetting from the pivot section and spaced from the base, wherein the handle is capable of rotating about an axis of the pivot shaft to lock with the base and to cause the pressing section to exert a force against the fan toward the base to securely attach the fan to the base.

An MTJ in an MRAM array or TMR read head is disclosed in which a capping layer has a bilayer configuration with a non-magnetic NiFeX inner layer on a NiFe free layer and a Ta layer on the NiFeX layer to improve dR/R and minimize magnetostriction. Optionally, a trilayer configuration may be employed where the Ta layer is sandwiched between an inner NiFeX layer and an outer Ru layer. The X component in NiFeX is preferably an element having an oxidation potential greater than Ni or Fe such as Mg, Hf, Zr, Nb, or Ta. NiFeX is preferably formed by co-sputtering a NiFe target with an X target at a forward power of about 200 W and 50 W, respectively. In an MRAM structure, the Mg content in NiFeMg may be increased to >50 atomic % to improve the gettering power of removing oxygen from the free layer.

The present invention relates to methods for detecting and/or measuring the activity of a specific kinase, with the methods comprising contacting one or more kinases with a binding agent to isolate a specific kinase of interest. The isolated kinase is then contacted with a kinase activity sensor, where the kinase activity sensor is comprised of a kinase recognition motif that is capable of being recognized by the isolated kinase, and at least one phosphorylation site. The isolated kinase phosphorylates the amino acid target of the kinase activity sensor and levels of the phosphorylated target amino acid can then be quantified.

A retainer (20) for a heat sink includes a supporting member (22), a bracket member (24), a pair of locking members (26) and an operating member (28). The supporting member defines a pair of openings (222) at opposite ends thereof. The bracket member is located above the supporting member and has a pair of abutting portions (246) extending therefrom. The locking members respectively pass through the openings of the supporting member and are pivotably attached to the bracket member. Each locking member has a spring portion (264) depressed on one of said abutting portions to maintain the locking member at a releasing position. The operating member is pivotable relative to the bracket member to cause the bracket member and the associated locking members to move upward and the supporting member to drive the locking members to turn toward each other to a locking position.
摘要:
Patterned, longitudinally and transversely antiferromagnetically exchange biased GMR sensors are provided which have narrow effective trackwidths and reduced side reading. The exchange biasing significantly reduces signals produced by the portion of the ferromagnetic free layer that is underneath the conducting leads while still providing a strong pinning field to maintain sensor stability. In the case of the transversely biased sensor, the magnetization of the free and biasing layers in the same direction as the pinned layer simplifies the fabrication process and permits the formation of thinner leads by eliminating the necessity for current shunting.

The retention device comprises a clip and a back plate engaging the clip, the clip comprises pressing members for press the heat sink onto the processor and at least a pair of hooks, the back plate is placed below a printed circuit board on which the processor is mounted, and comprises a body and at least a pair of retaining rings mounted thereof. The retaining rings travel through mounting holes in the printed circuit board and beyond the top surface thereof for catching the hooks of the clip.
摘要:
Two hitherto unreported novel hemiterpene glycosides were isolated in substantially pure form from the root of Ilex pubescens. The chemical structures and some properties of these hemiterpenes have been elucidated. These hemiterpene glycosides possess anti-platelet aggregation activity more potent than those of salvianolic acid B and aspirin and may be used in pharmaceutical compositions in humans and mammals in need of such treatment.

Improved performance of CIP GMR devices has been achieved by modifying the composition of AP2. Said modification comprises the addition of chromium or vanadium to AP2, while still retaining its ferromagnetic properties. Examples of alloys suitable for use in AP2 include FeCr, NiFeCr, NiCr, CoCr, CoFeCr, and CoFeV. The ruthenium layer normally used to effect antiferromagnetic coupling between AP1 and AP2 is retained.
摘要:
A method for forming a top spin-valve SyAP GMR read sensor having a novel conductive lead overlay configuration and the sensor so formed. The lead overlay electrically contacts the sensor at a position within the SyAP pinned layer, thus simultaneously assuring improved electrical contact and destroying the GMR properties of the sensor at the junction to improve the definition of the sensor track width.
