摘要： The present invention relates to treatments for atom probe components. For example, certain aspects are directed toward processes for treating an atom probe component that includes removing material from a surface of the atom probe component (e.g., using an ion beam, a plasma, a chemical etching process, and/or photonic energy). Another aspect of the invention is directed toward a method for treating an atom probe specimen that includes using a computing device to automatically control a voltage used in an ion sputtering process. Still other aspects of the invention are directed toward methods for treating an atom probe component that includes introducing photonic energy proximate to a surface of the atom probe component, annealing at least a portion of a surface of the atom probe component, coating at least a portion of a surface of the atom probe component, and/or cooling at least a portion of the atom probe component.

摘要： An atom probe provides rapidly pulsed field evaporation/desorption of ions from a tip utilizing a local extraction electrode positioned closely adjacent to the tip. A bias potential is applied between the tip and the local extraction electrode which provides an electric field at the tip which is less than but near the field intensity required for field evaporation of ions. Additional potential is applied between the tip and the extraction electrode in relatively low over-voltage pulses to obtain field evaporation of ions without substantially accelerating the ions. The ions extracted from the tip by the sharply defined pulses pass through an aperture in the extraction electrode and are accelerated by a large potential difference between the tip and a detector spaced from the tip and the local extraction electrode. An intermediate acceleration electrode may be positioned between the extraction electrode and the detector, with the acceleration electrode having an aperture therein to pass ions therethrough to the detector. The acceleration electrode is maintained at a higher potential with respect to the tip than the extraction electrode, and may be maintained at the same potential as the detector so that ions passed through the acceleration electrode coast to the detector. The use of relatively low voltage pulses to obtain evaporation of ions permits rapid repetition of the pulses, on the order of hundreds of thousands of pulses per second, to allow rapid accumulation of atom probe data.

摘要： A transducing head has a magnetoresistive sensor and a first and a second dual path conductor/magnet structure for providing current to the magnetoresistive sensor and for stabilizing the magnetoresistive sensor. The first and the second dual path conductor/magnet structures are arranged in an abutted-junction configuration on opposite sides of the magnetoresistive sensor. Each of the first and the second dual path conductor/magnet structures has at least one bias layer and at least one conductor layer. Each bias layer is formed upon a bias seed layer positioned over one of the conductor layers. Each bias seed layer is selected to result in the bias layer formed upon it having a coercivity between about 1 kOe and about 5 kOe and an in-plane remnant squareness greater than about 0.8. Most preferably, each of the first and the second dual path conductor/magnet structures is formed of at least two conductor layers interspersed with at least one bias layer.

摘要： A magnetoresistive sensor having an MR stack biased by high anisotropy hard bias elements thereby reducing distortion in sensor operation and improving head to head operational values. The high anisotropy hard bias elements are formed from a hard magnetic material deposited in a thin film having a substantially axial preferred direction of magnetic anisotropy prior to application of a setting field. The magnetic anisotropy in the hard magnetic material is formed by oblique deposition in a direction approximately normal to the preferred direction of anisotropy in the resulting hard bias element.

摘要： The forced air helmet heater and defroster system for sport and utility vehicles begins with a small motor driven blower. This blower is mounted or fastened to the vehicle and adapted to draw in cold, fresh air from the exterior of the vehicle and force it through a heat source. The heat source warms or tempers this cold fresh air. Then, depending on system configuration, the air exiting the heat source is either forced to an insulated helmet delivery conduit equipped with a break-away connection on the inlet end and a diffuser on the exit end, or it can first be routed to an optional temperature control junction and then to the insulated helmet delivery conduit. The vehicle rider may then place the delivery conduit's exit diffuser between the interior side of the helmet and their cheek or chin whereby the expelling warm air flushes the helmet's interior thus warming the rider's face and breathing air as well as keeping the rider's face shield and eyeglasses defrosted and fog free.

摘要： A magnetic sensor having adjustable electrical dimensions, such as electrical read width and electrical stripe height, is disclosed. The magnetic sensor includes a sensor stack with one or more bias electrodes positioned with respect to the sensor stack. The electrical width or electrical stripe height of the sensor stack is a function of a voltage applied to the bias electrodes. The electric field produced by the bias electrodes alters the electrical profile of the magnetoresistive device.
