摘要： A particulate matter concentration measuring apparatus is configured to measure a concentration of particulate matter in exhaust gas flowing through an exhaust line of a diesel engine. The apparatus includes an exhaust gas extraction line diverging from the exhaust line and having a flow passage cross-sectional area smaller than a flow passage cross-sectional area of the exhaust line. A particulate matter detection filter has a cell wall and is provided in the exhaust gas extraction line. A flow velocity of the exhaust gas passing through the cell wall is more than or equal to approximately 0.02 m/s and less than or equal to approximately 2.0 m/s. A differential pressure sensing part is configured to sense a differential pressure generated between an inlet and an outlet of the particulate matter detection filter.

摘要： A semiconductor pressure sensor includes a single crystal silicon substrate, a diaphragm, four diaphragm side walls enclosing the diaphragm, and a bridge circuit. The diaphragm is formed in the silicon substrate by etching the silicon substrate from a lower surface side of the silicon substrate. The diaphragm has a (110) plane orientation and a substantially parallelogram shape. The four diaphragm side walls have a (111) plane orientation and form two pairs of substantially parallel and opposite surfaces. The bridge circuit is formed on an upper surface of the silicon substrate. The bridge circuit includes a lead conductor and a strain gauge resistor. The bridge circuit is configured to detect pressure applied to the pressure sensor based on a change in an output value of the bridge circuit corresponding to an amount of flexure produced in the diaphragm by the pressure.
