This microelectronic component has an active face positioned within the substrate recess, a back face positioned outside the substrate recess, and a plurality of component contacts carried by the component active face and electrically coupled to the substrate contacts through the communication opening. This exemplary microelectronic component assembly may also include a mold compound which encapsulates the microelectronic component and a portion of the substrate active face. The mold compound may also substantially fill a gap between the periphery of the microelectronic component and a sidewall of the recess.Type: ApplicationFiled: August 29, 2002Publication date: February 19, 2004Inventor: Puah Kia Heng

Publication number: 20040031622Abstract: The present invention generally relates to an apparatus and method for removing hydrocarbons and other material from a wellbore. In one aspect, a method of drilling a sub-sea wellbore is provided. The method includes circulating a drilling fluid through a drill string from a surface of the sea to a drill bit in the wellbore. The method further includes pumping the fluid and drill cuttings from the sea floor to the surface with a multiphase pump having at least two plungers operating in a predetermined phase relationship. In another aspect, a fluid separator system having a first and a second plunger assembly is provided. The fluid separator system includes at least one fluid line for removing a fluid portion from the at least one plunger assembly and at least one gas line for removing gas from the first and a second plunger assembly.Type: ApplicationFiled: June 26, 2003Publication date: February 19, 2004Inventors: Bryan V. Butler, Gregory H. Chitty, Darcy Nott, Jeffrey C. Saponja, Peter B. Moyes

Publication number: 20040031623Abstract: A subsea return fluid recovery system for recovering drilling fluid and cuttings (“return fluid”) from a subsea wellbore in one embodiment includes a hub at the opening of the subsea wellbore that directs fluid into a transport device. In one embodiment, the hub includes a stand pipe that forms a return fluid column, the hydrostatic pressure of which causes return fluid to flow into the transport device rather than up the stand pipe. One or more buoyant members attached to the transport device convey the transport device toward the surface. A preferred recovery method includes collecting return fluid at the seabed, passively transporting the collected fluid to the surface, and processing the collected fluid at a local (offshore) or land based treatment facility. The retrieval and processing of the return fluid is done outside the critical path of the drilling activities at an offshore platform.Type: ApplicationFiled: March 18, 2003Publication date: February 19, 2004Applicant: Baker Hughes IncorporatedInventor: Peter Fontana

Publication number: 20040031624Abstract: An earth-boring bit has a seal assembly with a seal face having a DLC coating. The seal assembly locates between a bearing pin and a cone of the bit. The seal assembly has at least one rigid ring that rotates against a mating surface. The DLC coating is diamond-like carbon that may be coated by different processes onto either the ring, the mating surface, or both.Type: ApplicationFiled: August 19, 2002Publication date: February 19, 2004Inventors: Danny E. Scott, Chih C. Lin, Aaron J. Dick

Publication number: 20040031628Abstract: A method is provided to control at least one movement of an industrial truck. The method includes determining the lifting height of load holding means (5), determining the weight of a lifted load, calculatiing of the position of the overall center of gravity (S) of the industrial truck, calculating a variable which is a function of the stability of the industrial truck in at least one direction, and determining the allowable scope of the movement of the industrial truck. The overall center of gravity (S) and/or the stability of the industrial truck can be calculated taking into consideration a potential elastic deformation of a lifting platform (6) of the industrial truck.Type: ApplicationFiled: June 11, 2003Publication date: February 19, 2004Inventors: Hans-Jorg Schiebel, Michael Meinhardt, Ralf Mebert
