Abstract:
System for connecting in orthogonal position an auxiliary board to a double face or multilayer printed circuit base board, said base board (1) having internally metallized orifices (2) which are transverse to a dielectric substrate (3) and which interconnect electrically tracks (4) defined in one or two faces of said plate (1). Conductor members (5) of the auxiliary board (6) are inserted into the orifices (2) and are connected electrically to tracks (7) of said board; the conductor layer/surface lining internally the metallized orifices (2) is divided in various portions which are electrically separated. In said auxiliary board (6), a dielectric substrate (10) has appendices (8), each of which comprising various separated conductor parts (9a, 9b) which are connected to corresponding tracks (7a, 7b) of the board (6). The conductor parts (9a, 9b) of each appendice (8) correspond in number and position to those of the separated parts (2a, 2b) of each metallized orifice (2).
Abstract:
A multi-axis magnetometer (100) is provided having three magnetic field sensing circuits for sensing a magnetic field along the X, Y and Z axes. Each magnetic field sensing circuit includes an operational amplifier and a bridge chip (10) having at least one electrical conductor. The operational amplifier (12) is electrically connected to the at least one electrical conductor of the bridge chip (10) for receiving a portion of a current flowing through the at least one electrical conductor. The operational amplifier (12) provides an output voltage based on a magnitude of the portion of the current flowing through the at least one electrical conductor. The multi-axis magnetometer (100) further includes a voltage regulator (14) providing an operating voltage.

Abstract:
PROBLEM TO BE SOLVED: To provide a connector having a new and simple structure and capable of solving a problem about contact reliability in the case contaminant such as oil or grease is adhered onto a contact part. SOLUTION: A contact part or its vicinity in a conductive film is made to be a concavo-convex structure, and electric contact is provided by the convex part, and contaminant is removed by the concave part. As a configuration, for example, (1) a part corresponding to a contact part of an insulation film is made a concavo-convex shape, then a conductive pattern is formed, (2) a conductive pattern is directly processed into a concavo-convex shape, (3) a contact part is structured by a plurality of thin wires, and gaps between the thin wires are used for removing contaminant.
