Abstract: The disclosure is related to an uncoupled multi-phase inductor that includes a primary iron core, multiple secondary iron cores, multiple metal strip coils and multiple sheet members. The primary iron core includes multiple grooves, in which multiple middle cylinders are correspondingly installed. The middle cylinders in the primary iron core, the secondary iron cores in the grooves, and the metal strip coils are assembled. The sheet members are also integrated in the assembly for forming one single device with two or more inductors. For reaching a requisite inductance, the inductors administrate air gaps among the primary iron core and the secondary iron cores by the sheet members. The multi-phase inductor shares the middle cylinder with the primary iron core as one device so as to increase power density since the space can be saved. The device integrated with the two or more inductors has an extreme low coupling coefficient.

Abstract: A current sensor includes a printed circuit and current lines. The printed circuit comprises a stack, along a vertical direction, of metallization layers mechanically separated by electrically insulating layers, and a measurement or excitation coil wound around a vertical winding axis. The coil is formed by conductive tracks made in at least one metallization layer. One or more current lines are positioned in a plane parallel to the layers and are configured to be supplied with currents to be measured. The coil comprises turns formed by conductive tracks, made in respective metallization layers, electrically connected to one another by pads passing through at least one of the electrically insulating layers, to form a coil that extends along the vertical winding axis.

Abstract: A computer motherboard includes a printed circuit board which includes a central processing unit (CPU) socket and a group of memory slots. The group of memory slots includes an in-line type memory slot and a surface mounted device (SMD) type memory slot. The in-line type memory slot includes a number of plated through holes. The SMD type memory slot is set between the in-line type memory slot and the CPU socket. The through holes of the in-line type memory slot are connected to the CPU socket through traces, pads of the SMD type memory slot are connected to corresponding through holes of the in-line type memory slot having the same pin definition.

Abstract: A ferromagnetic thin-film based magnetic field detection system used for detecting the presence of selected molecular species. A magnetic field sensor supported on a substrate has a binding molecule layer positioned on a side thereof capable of selectively binding to the selected molecular species. The magnetic field sensor can be substantially covered by an electrical insulating layer having a recess therein adjacent to the sensor in which the binding molecule layer is provided. An electrical interconnection conductor can be supported on the substrate at least in part between the sensor and the substrate, and is electrically connected to the sensor. The magnetic field sensor can be provided in a bridge circuit, and can be formed by a number of interconnected individual sensors.

Abstract: A testing method for a magnetic recording medium which is magnetized measures variation of magnetization with the passage of time and evaluates the magnetic recording medium over its life. The method includes the steps of recording a first pattern at a density to be guaranteed in the magnetic recording medium, the first pattern having a difference between the sum total of areas of +bits and the sum total of areas of -bits, measuring remanence of the first pattern with the passage of time, and evaluating the magnetic recording medium over its life based on a measurement result.

Abstract: A full width single in-line memory module (SIMM) for dynamic random access memory (DRAM) memory expansions. A printed circuit board having a multiplicity of DRAM memory elements mounted thereto is arranged in a data path having a width of 144 bits. The SIMM further includes on-board drivers to buffer and drive signals in close proximity to the memory elements. In addition, electrically conductive traces are routed on the circuit board to reduce loading and trace capacitance to minimize signal skew to the distributed memory elements. The SIMM further includes a high pin density dual read-out connector structure receiving electrical traces from both sides of the circuit board for enhanced functionality. The SIMM is installed in complementary sockets one SIMM at a time to provide memory expansion in full width increments.

Abstract: An improved magnetic memory system in which binary data are stored as cross-tie, Bloch-line pairs, which are serially propagated downstream along a cross-tie wall in a magnetizable layer by appropriate drive fields. The magnetizable layer is configured into a data track whose two opposing edges are formed into patterns of asymmetrically shaped edges which form successive narrow portions with wide portions therebetween, and which are formed about the geometric centerline of the data track. The improvement comprises forming a plurality of energy wells along the geometric centerline of the data track and, transverse to the geometric centerline of the data track in the areas of the narrow portions where the cross-ties are stored but not in the areas of the geometric centerline.
