Abstract:
A communication Jack has a housing with a face having a plug receiving aperture. A conductive path pairs extends from corresponding plug interface contacts located at the plug receiving aperture to corresponding output terminate. A first circuit board is connected to the plug interface contacts and a second circuit board is connected to the plug Interface contacts and the output terminals. The first circuit board has a first single stage of crosstalk compensation with opposite polarity of the crosstalk of a plug for a first combination of the conductive path pairs. The second circuit board includes a second single stage of opposite polarity crosstalk compensation for some of the conductive path pairs not compensated on the first circuit board. The stages cancel substantially ail of the crosstalk caused by the plug, for the signal operating frequencies, for corresponding combinations of the conductive path pairs.

Abstract:
본 발명은 녹아 나온 땜납의 서로 이웃한 입력 전극으로의 유동을 방지하고, 또 입력 전극에 가해지는 전단 방향의 응력의 집중을 회피하는 가공이 실시되어 전극 사이의 쇼트나 단선을 방지하는 것을 목적으로 한다. 입력 전극(28)에 대응하는 슬릿 구멍(26)의 장벽은 요철 형상으로 되어 있다. 입력 전극(28)은 기판전극(30)과 중합되어 가열함으로써 땜납(32)가 녹아 양 전극(28 및 30)을 고정한다. 녹아 나온 땜납(32)는 베이스(22)와 기판(18A) 사이를 모세관 현상으로 유동한다. 이 땜납의 유동을 슬릿 구멍(26)의 장변에 철부(26A)를 형성하여 요철로 함으로써, 서로 이웃하는 입력 전극(28)을 접속하는 베이스(22)를 비직선으로 함으로써, 서로 이웃하는 입력 전극(28)로의 유동을 저지하고 있다. 또, 액정 셀(16)과 기판(18A 및 18B)가 상대 이동한 경우, 철부(26A)과 개개의 입력 전극(28)과의 접합부로, 각각 독립한 변형이 가능하게 되고 전단 방향의 응력의 집중이 회피되어 강도가 증가하고 있다.

Abstract:
A coil of a high current magnetic element (1) with a magnetic core (5) that is mounted on a substrate (2) is formed by pieces of thick U-shaped wires (7.1 - 7.8) that are fitted over the magnetic core (5) and into corresponding holes (6) in the substrate (2) and interconnected in the required manner by grooves (9.1 - 9.10) on the lower surface of the substrate that are plated with copper and filled with solder. In this manner, the manufacturing of high current magnetic elements where thick wires have to be wound around the core can be realised with a high degree of automation that is without the need to manually wind a thick wire around the magnetic core.
