摘要： Transducer assembly for an offshore drilling riser, in an example, includes a spool for connecting into the riser and a protrusion extending around the side wall of the spool. A recess extends around the protrusion between upper and lower sloping surfaces. Upper transducer bores are spaced around the protrusion and extend from the upper sloping surface downward and inward into the spool bore and lower transducer bores extend from the lower sloping surface upward and inward into the spool bore. A base of a rigid non-metallic material is located in each of the transducer bores. A seal ring extends around a cylindrical exterior portion of each of the bases and one of the transducer bores. An acoustic transducer element is mounted to the outer end of each of the bases. The transducer assembly can detect drilling fluid and form sealing.

摘要： A method to create piezoresistive sensing elements and electrostatic actuator elements on trench sidewalls is disclosed. P-type doped regions are formed in the upper surface of an n-type substrate. A trench is formed in the substrate (e.g. by DRIE process) intersecting with the doped regions and defining a portion of the substrate which is movable in the plane of the substrate relative to the rest of the substrate. Then diffusion of P-type dopant into the trench side-walls creates piezoresistive elements and electrode elements for electrostatic actuation. Owing to the intersection of two doped regions, there are good electrical paths between the electrical elements on the trench side-walls and the previously P-type doped portions on the wafer surface. The trench intersects with insulating elements, so that insulating elements mutually insulate adjacent electrical elements. P-n junctions between the electrical elements and the substrate insulate the electrical elements from the substrate.

摘要： A method to create piezoresistive sensing elements and electrostatic actuator elements on trench sidewalls is disclosed. P-type doped region(s) 25 are formed in the upper surface of an n-type substrate 20. A trench 22 is formed in the substrate (e.g. by DRIE process) intersecting with the doped regions and defining a portion 21 of the substrate which is movable in the plane of the substrate relative to the rest of the substrate. Then diffusion of P-type dopant into the trench side-walls creates piezoresistive elements 27 and electrode elements 29 for electrostatic actuation. Owing to the intersection of two doped regions, there are good electrical paths between the electrical elements 27, 29 on the trench side-walls and the previously P-typedoped portions 25 on the wafer surface. The trench 22 intersects with insulating elements 28, so that insulating elements 28 mutually insulate adjacent electrical elements 27, 29. P-n junctions between the electrical elements 27, 29 and the substrate 20 insulate the electrical elements 27, 29 from the substrate.
