Abstract:
A core-sheet assembly (30) includes a first sheet portion (1) having non-magnetic and insulating properties, and having a hole (2) of predetermined shape formed therein, a high permeability member (3) arranged in the hole (2), and a second sheet portion (4, 5) having non-magnetic and insulating properties, and bonded to the first sheet portion (1) by an adhesive agent (6). The high permeability member (3) forms a magnetic core. A plurality of conductive paths (20) are passed through the core-sheet assembly (30), and a plurality of conductive paths (22, 23) are formed on the assembly (30) to produce a coil-shaped conductive path around the magnetic core (3).
Abstract:
A flat flexible electrical cable includes a pair of pseudo-twisted conductors (3a, 3b) on a flexible dielectric substrate (2, d). Each conductor includes alternate straight (4) and oblique (5) sections. The straight sections (4) of the conductors are generally parallel to each other and of uniform width. The oblique sections (5) of the conductors cross each other at a crossover point (8). Each oblique section (5) of each conductor is reduced in width uniformly in a direction from the straight-to-oblique transfer point (7) of the respective conductor to the crossover point (8) of the conductors (3a, 3b).
Abstract:
A twisted-pair conductor line structure is formed on a substrate (22) having insulated conductive layers (10, 11). The conductive layers are used to form first, second, third, and fourth conductive planar segments (16). A first conductive link (17) joins the first and second planar conductive segments to provide a first signal path. Similarly, a second conductive link (17) joins the third and fourth planar conductive segments to provide a second signal path. The first and second conductive links are operatively arranged to form a twist (17) in the first and second signal paths, such that the resulting magnetic fields (57, 59) around the twisted conductive segments will be opposite to each other for cancelling each other out, in order to reduce the magnetic field radiation to the surrounding environment.
Abstract:
An electrical circuit package wherein a flexible support member (11) having conductive materials (91, 94) and electronic components thereon is fused with a substrate (12) which acts as a support for the film. This results in a unitary packaged circuit. In one embodiment the film is a decal on which certain portions have a substrate fused thereto. In other embodiments, various layers of conductive materials (91, 94) are applied and molded into the substrate (12) to form a variety of electronic functions. The circuit package lends itself to high production and reliability as well as cost savings.

Abstract:
Printed circuit panel for reducing cross talk between electrical circuit conductors (17, 18, 19, 20) wherein the conductors lie within individual parallel channels (13) within the same plane or different parallel planes within the induced voltage or cross talk region of an energized and a quiet conductor and either converge or diverge with respect to each other. The amount of relative convergence or divergence, preferably more than six degrees and less than 15 degrees, is that required to attenuate the magnitude of any signal induced by the activated conductor in a neighboring or quiet conductor to maintain an acceptable and desired signal-to-noise ratio.
Abstract:
Leiterplatte, die zur Verdrahtung von Geräten auf mindestens einer ihrer Seiten Zweidraht-Leitungen (1,2,3,4) aufweist, die voneinander und von Fremd-Störfeldern entkoppelt sein sollen. Hierzu werden die Zweidraht-Leitungen (1,2,3,4) verdrillt, indem in Abständen Durchkontaktierungen (7,8,12,13) vorgesehen sind, mit deren Hilfe jeweils ein Leiter der Zweidraht-Leitungen um den anderen herumgeführt (11,11a) ist.
Abstract:
Die vorliegende Erfindung bezieht sich auf eine Anschlußvorrichtung für ein im Randbereich mit Anschlüssen versehenes, plattenförmiges elektrisches Gerät, vorzugsweise einem Mikropack, mit Leiterzügen (6) einer Leiterplatine (1). Die Leiterplatine (1) ist hier mit einem der Größe der Platte (Filmabschnitt 8 des Mikropack) im wesentlichen angepaßten Fenster (2) versehen, dessen Fensterränder elastisch nachgiebige Haltezungen (4, 5) unterschiedlicher Länge aufweisen, die zumindest teilweise Leiterzugsenden (6) bilden, die mit den Anschlüssen (10) im Randbereich des Mikropacks korrespondieren. Hierdurch ergibt sich eine einfache Halterung des Gerätes bzw. des Mikropacks zwischen den Haltezungen, da bei Eindrücken des Mikropacks die kürzeren Zungen auf die Oberseite springen und die längeren Zungen auf der Unterseite verharren, so daß der Rand des Mikropacks zwischen den kurzen und den langen Haltezungen eingespannt ist.
Abstract:
Disclosed herein are printed circuit boards (100) with embedded solenoid filters (110A-L, 120A-K) through which signal traces (140) pass to filter unwanted noise and electromagnetic interference. A printed circuit board (100) comprises a least three layers (102, 104, 106), a solenoid embedded within the at least three layers, and at least one trace (140) extending through the solenoid. The insertion loss characteristics of the solenoid filter can be tuned by modifying the number of turns in the solenoid(s) and the width (160) of the solenoid(s). The solenoid filter may comprise multiple solenoids connected in series, with adjacent solenoids having opposite wind directions. Surface components may be included on the board to tune the insertion loss further.
