Abstract:
An output adapting device of a plug-in power system is used to connect an output terminal of the plug-in power system with an input terminal of an electronic device, so as to transmit the power from the plug-in power system to the electronic device. The adapting device includes an output adapting terminal and an input adapting terminal respectively corresponding to the output terminal and the input terminal, in which corresponding pins of the corresponding terminals have identical potential, and at least one corresponding pair of pins of the output adapting terminal and the input adapting terminal have different potential. Furthermore, the adapting device also includes an adapting unit for adapting and outputting the power from the output adapting terminal to another pin with identical potential of the input adapting terminal. Therefore, the output terminal of the plug-in power system can be standardized for widely applying in various electronic devices.
Abstract:
A semiconductor module includes a plurality of rectangular shaped semiconductor devices which are arranged in two rows such that each pair of adjacent semiconductor devices is in orientations differed by 90 degrees from each other. A plurality of wirings connect the semiconductor devices included in one of the two rows to the semiconductor devices included in the other row such that the semiconductor devices arranged in the same orientations are connected to each other.
Abstract:
A multilayer wiring board includes at least two wiring boards having wiring layers containing wiring patterns formed on both sides. A pair of fin-shaped bumps are formed at desired positions on wiring patterns on the surfaces facing each other, of the wiring boards, so that the bumps assume a slender shape as seen in plan view and that the bumps intersect each other. The pair of fin-shaped bumps are electrically connected to form an inter-board connection terminal. Further, an insulating layer is formed between the wiring boards, and protection films are formed to cover the entire surface except pad areas defined at predetermined positions on outer wiring layers of the wiring boards.

The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes a multi-zone crosstalk compensation arrangement for reducing crosstalk at the jack.

The invention relates to a high frequency component of layered structure, and a method for manufacturing the component. The component comprises at least one dielectric layer parallel to the layers of the layered structure, at least two transmission lines for transmitting electrical signals, at least one capacitor, each of which is formed by overlapping parts of two transmission lines, the overlapping parts being for forming capacitive interaction between the parts, and the overlapping parts being arranged to overlap each other in a transversal direction to a dielectric layer parallel to the layers of the layered structure, the dielectric layer being in between the overlapping parts.

A communications connector includes: a dielectric mounting substrate; a plurality of conductors mounted in the mounting substrate; and a wiring board. Each of the conductors includes a fixed end portion mounted in the mounting substrate and a free end portion, each of the free end portions being positioned in side-by-side and generally parallel relationship, and each of the fixed end portions being positioned in side-by side and generally parallel relationship. The wiring board is positioned between the fixed and free end portions of the conductors, the wiring board being generally perpendicular to the conductors, the wiring board including first and second conductive traces that are electrically insulated from each other. First and second conductors are electrically connected with the first and second traces. The first and second conductive traces are arranged on the wiring board to create a crossover between the first and second conductors.
Abstract:
A memory module substrate printed-circuit board (PCB) has multi-type footprints and an edge connector for mating with a memory module socket on a motherboard. Two or more kinds of dynamic-random-access memory (DRAM) chips with different data I/O widths can be soldered to solder pads around the multi-type footprints. When ×4 DRAM chips with 4 data I/O pins are soldered over the multi-type footprints, the memory module has a rank-select signal that drives chip-select inputs to all DRAM chips. When ×8 DRAM chips with 8 data I/O pins are soldered over the multi-type footprints, the memory module has two rank-select signals. One rank-select drives chip-select inputs to front-side DRAM chips while the second rank-select drives chip-select inputs to back-side DRAM chips. Wiring traces on the PCB cross-over data nibbles between the solder pads and the connector to allow two ×4 chips to drive a byte driven by only one ×8 chip.
Abstract:
A printed circuit board includes a first conductive plane and a second conductive plane substantially parallel to the first conductive plane. The printed circuit board includes a via signal barrel transecting the first and second conductive planes and a first anti-pad positioned between the first conductive plane and the via signal barrel. The first anti-pad has a first voided area. The printed circuit board includes a second anti-pad positioned between the second conductive plane and the via signal barrel. The second anti-pad has a second voided area. The first voided area does not completely overlap the second voided area.
