Abstract: An acoustic transducer includes a sound-producing member at least partially disposed within the first magnetic flux gap region between the magnetic poles. The sound-producing assemblage is magnetically excited through a magnetic circuit that passes from a location outside the magnetic flux gap region to inside the magnetic flux region through an air gap. The moving member is controllably movable under the influence of at least one varying magnetic field, and its movement is constrained by a unique combination of mechanical restraints and magnetic restraints imposed upon the moving member by the interaction of a plurality of magnetic fields.

Abstract: A method for manufacturing a magnetic write pole of a magnetic write head for perpendicular magnetic recording. A magnetic write pole material is deposited, followed by union milling hard mask, a polymer mask under-layer followed by a dielectric hard mask material, followed by a photoresist. The photoresist is patterned to define a write pole shape and the shape of the patterned photoresist is transferred onto the underlying dielectric hard mask by a novel reactive ion etching that is performed in a chemistry that includes one or more fluorine containing gases and He. The presence of He in the reactive ion etching tool helps to improve the profile of the patterned dielectric hard mask. In addition, RIE parameters such a gas ratio (e.g. CF4 to CHF3 gas ratio) and power ratio (e.g. source power to bias power) are adjusted to optimize the profile of the patterned dielectric mask.
Abstract translation: 一种用于制造用于垂直磁记录的磁写头的磁写磁极的方法。 沉积磁性写入极材料，随后是联合铣削硬掩模，聚合物掩模底层，随后是电介质硬掩模材料，随后是光致抗蚀剂。 光致抗蚀剂被图案化以限定写磁极形状，并且通过在包括一种或多种含氟气体和He的化学中进行的新型反应离子蚀刻将图案化光致抗蚀剂的形状转印到下面的电介质硬掩模上。 反应离子蚀刻工具中He的存在有助于改善图案化电介质硬掩模的轮廓。 此外，调整诸如气体比（例如CF4至CHF3气体比）和功率比（例如源功率与偏置功率）的RIE参数以优化图案化电介质掩模的轮廓。

Abstract: A solid marine seismic cable assembly includes a cable, hydrophone housings, a buoyant filler, and an outer protective jacket. The cable includes a load-bearing fiber bundle, data-transmitting wires, power conductors, optical fibers, and a protective sheath. The data-transmitting wires, power conductors, and optical fibers surround the load-bearing fiber bundle. The protective sheath surrounds the assembly of the data-transmitting wires, power conductors, optical fibers, and the load-bearing fiber bundle. The hydrophone housings affix around the cable in a spaced-apart relationship. Each hydrophone housing includes a hydrophone module, and each hydrophone module contains a hydrophone. The buoyant filler surrounds the cable, and separates the hydrophone housings. The outer protective jacket surrounds the hydrophone housings and the buoyant filler, enclosing the cable assembly.

Abstract: A piezoelectric vibrator comprises a piezoelectric element having a rectangular shape and being provided with at least one input electrode from which an input lead extends and at least one output electrode from which an output lead extends; and a case having a rectangle-like shape for accommodating the piezoelectric element and having at least through holes through which the input and output leads penetrate thereby the leads project to an exterior of the case. The through holes have a size larger than a size of the leads to create a clearance between the leads and inner walls of the through holes so as to allow the leads to show a displacement or a vibration due to the vibration of the piezoelectric element. The case has a size larger than a size of the piezoelectric element for forming gaps between the piezoelectric element and the case to allow the piezoelectric element to be freely vibrate, the piezoelectric element being merely placed on a bottom of the case but not fixed nor adhered thereon to allow the piezoelectric element to be freely vibrated.
