    摘要: A magnetoresistive write element has a plurality of coils disposed between a first and second pole. A first coil having inner and outer contacts is provided on top of a layer of insulation on top of the first pole. A write gap material above the first coil separates the poles at a yoke tip region to form a write gap therebetween. Second and third coils wound in the form of a single bifilar coil are provided on top of the write gap material, each having an inner and an outer contact portion. Electrical connection between the inner contact of the first coil and the inner contact of the second coil is provided through a via in the write gap material. An insulation layer above the second and third coils provides separation from a fourth coil provided thereabove. The fourth coil also has inner and outer contact portions. The outer contact of the fourth coil electrically connects with the outer contact of the second coil through one of the vias in the second insulation layer separating the second and third coil from the fourth coil. Similarly, the inner contact of the fourth coil connects electrically with the inner contact of the third coil. An insulation layer is deposited on top of the fourth coil and the second pole is formed on top thereof such that the first and second poles make electrical connection with one another at back gap portion.

    摘要: In a preferred embodiment, a thin film write head having upper and lower pole structures. In the preferred embodiment of the present invention, a middle coat insulation layer is located over a yoke of the lower pole structure and adjacent a pedestal pole tip of the lower pole structure. A trench is formed in the middle coat layer by etching part way into the middle coat layer. A conductor coil is formed on the middle coat so that a portion of the coil is located within the trench and a portion above the trench. Preferably, the middle coat is planarized and then etched using a resist mask to form the trench. With one method, the resist mask is removed after etching the trench, a conductor seed layer deposited, a resist mask formed on the seed layer, a conductor coil formed within the mask, and the seed layer etched after resist mask removal to electrically isolate the turns of the coil. In another method, after trench etching and resist mask removal, conductor material may be deposited on the middle coat and planarized to form the portion of the coil within the trench. With this method, additional conductor material is deposited on the conductor material in the trench using a resist mask to form the coil. The additional conductor material provided in the trench can significantly reduce the coil resistance without increasing stack height or yoke lengths to improve write head performance.

    摘要: A harness for an upper extremity below-elbow prosthesis. The harness includes a humeral cuff having medial and lateral pivot arms configured to removably attach to the socket of a below-elbow prosthesis. The humeral cuff enables a user to suspend the prosthesis without the need of a shoulder strap/harness or body harness. A cable system is affixed to the pivot arms and includes a wheel coupling the pivot arms to the control arm of a hook of the below-elbow prosthesis, thereby enabling users to operate the hook by simple flexion and extension of their arm.

    摘要: Modular convertible furniture systems include a pair of similar open-ended box frame assemblies which are nestable one within the other. A pair of slotted support rails are attached pivotally at respective opposing corners of one of the box frame assemblies so as to be movable between raised and lowered positions. When in a raised position, the rails provide a support for a solid board plank thereby becoming a seat back (e.g., for a chair, love seat, or sofa-type arrangement). When the rails are in a lowered position substantially parallel to the ground, the two box frame assemblies may be oriented back-to-back so as to provide a support for a mattress thereby converting the structure into a bed arrangement, for example. The box frame assemblies can be positioned on different sides and ends thereby allowing formation of tables and/or shelving as may be desired.

In certain embodiments, the main tube comprises a single continuous tubular body extending uninterrupted from a widened proximal end portion through a narrow medial portion to a widened distal end portion. An objective is disposed in the widened distal end portion of the tubular body and an ocular is disposed in the widened proximal end portion of the continuous tubular body. A zoom selector ring is located about a circumference of the narrow medial portion of the continuous tubular body. The zoom selector ring can be used to provide optical zoom. In one arrangement, the zoom selector ring includes a plurality of segments arranged circumferentially about the circumference of the narrow medial portion. A flexible erector assembly that includes erector optics may be included in the main tube. This flexible erector assembly may flex to adjust windage and elevation.

    摘要: A compact, light-weight binocular includes motorized optical adjust. The binocular includes a pair of telescopic sections connected to a bridge section positioned between them. Each telescopic section includes an eyepiece lens group, a prism element, an intermediate focus lens element, and a fixed objective lens. A high-speed focus motor and a speed-reduction gear assembly are positioned on the bridge section and operably coupled to the intermediate focus lens elements. A user-operated focus control is selectively operated by a user to activate the focus motor and adjust focus of the binocular.
