| 20080253021 | Non-magnetic contact enhancement feature - A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable beyond the external contact surface. The contact member surrounds at least a portion of the extendable writer portion. | 10-16-2008 |
| 20110058278 | HIGH STROKE EFFICIENCY AIR-BEARING DESIGN - This disclosure is directed to air-bearing sliders used in magnetic storage systems that employ a trench arranged between a transducing head connected to a slider body and a leading edge of the slider body. The trench is configured to divert air passing over an air-bearing surface of the slider body away from the transducing head. | 03-10-2011 |

| 20090184696 | VOLTAGE SOURCE FOR GATE OXIDE PROTECTION - An electronic circuit. The electronic circuit includes a first circuit leg coupled to a first supply voltage node and a second supply voltage node. The first circuit leg includes a first reference current circuit configured to produce a first reference current and a second reference current circuit configured to produce a second reference current. The electronic circuit further includes a second circuit leg coupled in parallel with the first circuit leg. The second circuit leg includes a first transistor coupled to form a current mirror with the first reference current circuit and a second transistor coupled to form a current mirror with the second reference current circuit. The source terminals of each of the first and second transistors are coupled together to form a third supply voltage node | 07-23-2009 |

| 20080278155 | System and Use Concerning Under Water Eddy Current Measurements on Components for Nuclear Reactors - The invention concerns a system suited for carrying out eddy current measurements on components for nuclear reactors when these components are located in water. The system comprises a control unit, a measurement probe and a first cable suited to constitute at least a part of the connection between the control unit and the measurement probe. The system also comprises a switching unit, suited to be located in water and arranged to be connected with said first cable, and to be connected with the measurement probe. The switching unit has a switching device which can assume at least a first and a second state. In the first state, the first cable is connected with the measurement probe. In the second state, the first cable is not connected with the measurement probe. The invention also concerns the use of the system. | 11-13-2008 |
