Abstract: A fuel filtration system and methods controlling, and operating a fuel filtration system. A first fuel filter head is fluidly coupled to one or more first fuel filters, a second fuel filter head is fluidly coupled to one or more second fuel filters and a selector valve is coupled to the first fuel filter head and the second fuel filter head. The selector valve includes a primary valve inlet port, a primary valve outlet port, and a movable valve body movable from a first position to a second position. The first position fluidly couples the first fuel filter head to the primary valve outlet port and fluidly decouples the second fuel filter head from the primary valve outlet port. The second position fluidly couples the second fuel filter head to the primary valve outlet port and fluidly decouples the first fuel filter head from the primary valve outlet port.

Abstract: A resistive touch panel including a base layer is disclosed. The touch panel includes a resistive layer covering the active area of the touch panel. The touch panel also includes a plurality of electrodes disposed to induce a voltage gradient across the resistive layer. The touch panel also includes a linearization pattern comprising a plurality of resistors disposed over at least a portion of the resistive layer for maintaining the uniformity of the voltage gradient across the resistive layer. The touch panel also includes an insulator covering a least a portion of the linearization pattern. The insulator reduces changes in the voltage gradient over time. A method of making a resistive touch screen is also disclosed.

Abstract: A pressure sensitive spacer coating for a touch screen may include a silicone adhesive material dissolved in a solvent. A touch screen may also include a first layer including a first conductive coating, a second layer including a second conductive coating, and a silicone pressure sensitive adhesive disposed between the first layer and the second layer. A method of manufacturing a touch screen may include providing a first layer having a first translucent conductive surface. The method may also include providing a second layer having a second translucent conductive surface. The method may also include applying an adhesive solution including silicone on at least one of the first conductive surface and the second conductive surface. The touch screen can be an analog or a matrix resistive touch screen. The adhesive can be applied by screen printing. The adhesive can be mixed with a slow evaporating solvent before screen printing.

Abstract: A slider of the type for use with a rotatable magnetic disk is disclosed. The slider has two ends and a bottom surface which includes an air bearing surface. An adhesive layer and continuous coating of carbon is located on the air bearing surface. A method of sputter depositing this continuous layer of carbon upon the air bearing surface of the slider is also provided. The continuous layer of carbon is crown-shaped and deposited using the sputtering technique. The carbon is directed from a source at the air bearing surface of a slider. A mask is placed between the source and slider so that the carbon is deposited in a crown shape. When the slider is viewed from front to rear the maximum depth of the coating is less than about 6 to 10 nm, while at the ends of the slider the coating depth is near 0 nm. The resistivity of the protective carbon layer is controlled for the additional benefit of protection from damages by electrostatic discharge.

Abstract: A magnetic head assembly having a transverse guiding surface which is highly resistant to being abraded by a recording medium for reading and recording magnetically recorded information on the recording medium including a transducer having a transducing element on one end thereof and conductive leads extending from a different end thereof, a substrate formed of a mixture of Aluminum Oxide and Titanium Carbide ("Al.sub.2 O.sub.3 --TiC") having a medium contacting surface and a supporting surface extending substantially perpendicular therefrom wherein the substrate has the transducer rigidly affixed to the substrate supporting surface with the transducing element positioned adjacent the substrate contacting surface, a spacer formed of Al.sub.2 O.sub.

Abstract: A thin film transducer having a substrate, a first and second pole piece formed of a selected magnetic material and terminating in a gap, a coil positioned between the first and second pole pieces and a magnetically conductive layer formed of a material having selected chemical, magnetic and physical properties and having a known magnetic saturation flux density and being positioned contiguous at least one of the first pole piece and second pole piece and rearward of the edges forming the gap to conduct magnetic flux in parallel to the pole pieces and to increase and concentrate the magnetic flux density at the edges of the first and second pole piece defining the gap is shown.

Abstract: This device provides for a substantially orthogonal transition or connection point between a strip transmission line configuration (one conductor, or two conductors sandwiched around a dielectric support, positioned in air between two ground planes such as might be used in a microwave antenna feed network) and a coaxial line section. The particular construction of the "side-launch transition" suppresses spurious parallel plate modes, and, in the case of two conductors surrounding a dielectric, trapped modes which occur between the two conductors. A U-shaped upper "dam" and corresponding lower "dam," electrically interconnected at several points, surround the termination of the stripline conductor(s) and provide suppression of parallel plate moding at the transition. In the case of two conductors surrounding a dielectric, electrical interconnection at the terminal point of the stripline conductors suppresses the trapped modes before they can be launched.
