20100000863 | PARTICULATE MATTER DETECTION DEVICE - A particulate matter detection device | 01-07-2010 |
20100071441 | PARTICULATE MATTER DETECTION DEVICE AND METHOD FOR MANUFACTURING THE SAME - A particulate matter detection device including a main body which has one end provided with a through hole; a pair of electrodes embedded in a wall through which the through hole is formed, and covered with a dielectric material; wires extending from the electrodes to the other end of the main body; and a ground electrode provided at a position sandwiched between the wires. The device can electrically adsorb, on the wall surface of the through hole, a charged particle in a fluid flowing into the through hole, or a particle charged by electric discharge caused in the through hole by applying a voltage across the pair of electrodes. The device can measure the changes of the electric properties of the wall through which the through hole is formed, thereby detecting particles adsorbed on the wall surface of the through hole. | 03-25-2010 |

20120055233 | PARTICULATE MATTER DETECTION DEVICE - A particulate matter detection device includes a plate-like element base material including, on one surface thereof, a formed recess portion to collect a particulate matter; a pair of measurement electrodes arranged on the bottom surface side of the recess portion of the element base material; and a high-voltage dust collection electrode embedded in a wall which forms the recess portion of the element base material on the one surface side of the element base material from a position where the pair of measurement electrodes are arranged. An electric field is generated from the high-voltage dust collection electrode to the pair of measurement electrodes, to collect, on the bottom surface side of the recess portion, the particulate matter flowing along the element base material, and a change of electric characteristics between the pair of measurement electrodes is measured to detect the particulate matter collected on the recess portion. | 03-08-2012 |
