  • Apparatus and method to reduce electromagnetic emissions in a multi-layer circuit board
    Patent number: 5357050
    Abstract: A method for defining traces on a multi-layer circuit board suppresses electro-magnetic emissions radiated from the traces. The defined traces carry a differential signal. Layers of signal and return trace pairs are formed. Each succeeding layer of traces is spaced above and follows the traces below, with the succeeding signal trace positioned above the preceding return trace and the succeeding return trace positioned above the preceding signal trace. All of the signal traces are conductively connected and all of the return traces are conductively connected. The symmetry of the arrangement causes the electro-magnetic fields generated by the conductors (traces) to cancel at any appreciable distance. Additionally, varying combinations of layers and/or varying parameters such as dimension, spacing and dielectric material, results in a desired impedance for matching to external cabling and the like.

  • Branch off
    Patent number: 5347089
    Abstract: An arrangement for enclosing a branch-off between a pair of cables (2,3,4) comprises a dimensionally recoverable sleeve (5) which can surround the branch-off, and one or more clips (6) which can be positioned about opposed walls of the sleeve to divide the sleeve into channels for the cables. The or each clip (6) is of unitary form and has a pair of legs (8) that are splayed outwardly to facilitate positioning of the clip over the sleeve walls. The or each clip is deformable so that the legs can be forced towards each other after the clip has been positioned on the sleeve walls but is sufficiently rigid, at least in its deformed state, it will resist opening out of the legs under the recovery forces of the sleeve.The invention provides a relatively simple and easy to install enclosure for branch-offs in harnesses for example that are intended to be used in automotive vehicles.

  • Insulated electrical conductor wire having a high operating temperature
    Patent number: 5336851
    Abstract: An insulated wire has a conductor, a first insulating metal oxide layer which is formed around the conductor, and a second insulating metal oxide layer, containing ceramic particles mixed by addition and formed around the first insulating metal oxide layer. The so formed insulating metal oxide layers are produced by changing a precursor of a metal oxide into the ceramic state. This change is caused by a method such as a sol-gel method or a thermal decomposition method. The mixed ceramic particles are more preferably in the form of fine platelets. This insulated wire has an excellent flexibility, emits no gas, can maintain its insulation even at a high temperature, and has a high breakdown voltage.
