  • Patent number: 8875379
    Abstract: Methods of manufacturing a fluid flow measuring device are provided. In an embodiment of the present invention, shields are disposed to prevent or reduce circulating electrical currents from causing a voltage difference that would adversely affect the measured voltage difference between two adjacent electrodes. Groups of sensors, e.g., two or more, may be placed within the shield. The shields may have any cross-section shape. A magnetic field source is disposed proximate the electrodes such that the magnetic field source is oriented to generate a magnetic field substantially orthogonal to an imaginary line intersecting each pair of electrodes. A voltage measuring circuit is electrically coupled to the plurality of electrodes and configured to measure a voltage difference between each pair of electrodes.

  • Patent number: 8850691
    Abstract: A manufacturing method for a heating resistor element includes a concave portion forming step, a bonding step and a resistor forming step. The concave portion forming step includes forming a concave portion on at least one of bonded surfaces between an insulating substrate and a heat accumulating layer. The bonding step causes the bonded surfaces between the insulating substrate and the heat accumulating layer to adhere to each other to bond the insulating substrate and the heat accumulating layer. The resistor forming step includes forming a heating resistor at a position on the heat accumulating layer. The position is opposed to the concave portion. The concave portion forming step further includes processing an inner surface of the concave portion on a side of the insulating substrate to have surface roughness Ra of 0.2 ?m or more.
