  • Publication number: 20180158474
    Abstract: A method for manufacturing a magnetic write head having a heat sink structure, wherein the magnetic write head is free of voids at the media facing surface. After forming the write pole, a chemical mechanical polishing process is performed prior to defining the heat sink structure. Planarizing the write pole structure by chemical mechanical polishing prior to forming the heat sink structure advantageously reduces the topography over which the heat sink structure. This mitigates shadowing effects from the write pole structure and prevents the formation of voids at the media facing surface.

  • Publication number: 20180158473
    Abstract: A magnetic write head for heat assisted magnetic recording having a novel heat sink structure. The write head includes a magnetic write pole and a thermal transducer located adjacent to a leading edge of the magnetic write pole. A heat sink structure, constructed of a non-magnetic, thermally conductive material such as Au, Ag or Cu partially surrounds the magnetic write pole. The heat sink structure can be formed to contact first and second sides of the magnetic write pole, and can be recessed from the media facing surface of the write head. The space between the heat sink structure and the media facing surface can be filled with a physically hard, non-corrosive metal.

  • Patent number: 9726103
    Abstract: A fuel injection amount control apparatus comprises an air-fuel ratio sensor disposed between an exhaust gas merging portion and an upstream catalyst. The control apparatus performs a feedback correction on an amount of fuel to be injected by the fuel injection valve so that an air-fuel ratio represented by the output value of the upstream air-fuel ratio sensor becomes equal to a target air-fuel ratio set at stoichiometric air-fuel ratio. The control apparatus obtains an air-fuel ratio imbalance indicating value, which becomes larger as a difference in air-fuel ratio of each of the mixtures supplied to each of the combustion chambers among the cylinders becomes larger, and performs an increasing correction to the instructed fuel injection amount in such a manner that an air-fuel ratio determined by the instructed fuel injection amount becomes richer than the stoichiometric air-fuel ratio as the obtained air-fuel ratio imbalance indicating value increases.
