摘要： A wafer level test structure and method detects multiple magnetic domains and magnetic domain instability in a test magnetic element. The apparatus comprises a first MR sensor designed to be held in a single magnetic domain by shape anisotropy and a second MR sensor having a permanent magnet to hold the element in a single magnetic domain. A circuit connects the first and second MR sensors to detect differences between the changes in resistance between the first and second sensors in the presence of a magnetic field or differences in resistance after the application and release of a magnetic field. The circuit is preferably a balance circuit in which imbalance in the presence of a magnetic field indicates the presence of multiple magnetic domains in at least one of the test sensors. Magnetic domain stability may be tested by applying an external field to disrupt the existing single domain state of the test sensors, and thereafter detecting differences in resistance of the sensors during reversal of the magnetic field.

摘要： A cutter attachment for a mono-filament type trimmer implement including a trimmer support shaft and a cutter in the form of a rotatable mono-filament used for lawn trimming mounted at a free end thereof. The cutter attachment has a base secured to the trimmer support shaft above the cutter. An elongated swingable rod shaped guard has a closed guard end and a pair of free ends positioned in adjacency to the base. An attachment device joins the free ends of the guard to the base enabling the elongated swingable rod shaped guard to be swung from a "storage position" where the closed end of the guard rests on and overlies the shaft in a "guard position" where the closed guard end overlies the cutter for protecting shrubs, trees and the like. The guard is a triangularly shaped open ended rod that is secured by the attachment device to a conventional commercial type whip type weed cutter.

摘要： A two-dose autoinjector for a medicament wherein the locking and releasing of the drive spring of the autoinjector is controlled through stepped guides with ramps for two successive slidings of slides operated by the spring and connected with the syringe and plunger. The guides and the slides are pivotable relative to one another and the sliding direction, while the syringe can only slide axially. To enable or disable the sliding of the slides within the guides an angularly angularly mobile arming member is provided formed with a guide track substantially equal to that of the stationary member where the guides are formed.

摘要： A read/write head includes a bottom shield and a shared shield. The shared shield includes a first domain and a plurality of closure domains. The read/write head also includes a magnetoresistive sensor deposited adjacent an air bearing surface between the bottom shield and the shared shield. The magnetoresistive sensor includes a magnetoresistor aligned with the first domain. Non-magnetic material separates the magnetoresistive sensor from the bottom shield and the shared shield. The shared shield includes a shaped feature that defines an unambiguous direction of magnetization for the first domain.
