    摘要： The method and system provide a perpendicular magnetic recording (PMR) head having an air bearing surface (ABS). The PMR head includes first and second poles each having front and back gap regions, a first nonmagnetic insertion layer between the back gap regions, a magnetic pole layer with a front terminating at the ABS, a write gap, shield(s), a second nonmagnetic insertion layer between the second pole back gap region and the shield(s), and coil(s) between the shield(s) and the first pole. The magnetic pole layer terminates between the ABS and the second pole back gap region and has pole angle(s) of at least thirty and not more than fifty degrees. At least part of the magnetic pole layer resides on the second pole. Part of the shield(s) are adjacent to the write gap. Another part of the shield(s) is coupled with the second pole back gap region.

    摘要： An evaporative condenser radiating module for steam exhaust of a steam turbine comprises tube bundles and steam-water separating chambers. A steam-water separating chamber (4) between a section A and a section B, a section A downflow cooling section tube bundle (3), a section B downflow cooling section tube bundle (5), and a counter flow cooling section tube bundle (8) are disposes at the left side of a central steam-water separating chamber (7). An upper sealed space (10) of the steam-water separating chamber (4) between the section A and the section B is in communication with the central steam-water separating chamber (7) through the counter flow cooling section tube bundle (8). A lower sealed space of the steam-water separating chamber (4) between the section A and the section B is in communication with the central steam-water separating chamber (7) through the section B downflow cooling section tube bundle (5). A sealed section A steam entering chamber (2) is arranged on the left side of the steam-water separating chamber (4) between the section A and the section B. The section A downflow cooling section tube bundle (3) is arranged between the section A steam entering chamber (2) and the lower sealed space of the steam-water separating chamber (4) between the section A and the section B. The right side of the central steam-water separating chamber (7) is provided with tube bundles and steam-water separating chambers totally structurally identical with those arranged on the left side of the central steam-water separating chamber (7).

    摘要： A method of fabricating a perpendicular magnetic recording (PMR) head with a multi-level tapered write pole which creates an efficient channeling of magnetic flux to the pole tip. A tapered bottom yoke is first formed in an etched substrate and a write pole is formed on the tapered bottom yoke. The write pole comprises a main pole with a tapered tip. A tapered top yoke is then formed on the write pole and symmetrically positioned relative to the bottom yoke. The edge of each yoke is recessed from the ABS of the tapered tip, giving the write pole a stepped profile. The tapered tip can be two sloped surfaces that are symmetric about a mid-plane of the main pole or a single sloped edge on the leading side or the trailing side of the pole.
