20110252865 | PARTICULATE MATTER DETECTING DEVICE - The particulate matter detecting device of the present invention includes: a sensor element having a plate-shaped element substrate, at least one pair of measurement electrodes arranged on one end face of this element substrate, a heater electrode arranged on either of end faces or inside of the element substrate, and a plurality of lead terminals arranged on the other end face of the element substrate and electrically connected to each of the measurement electrodes and the heater electrode; and an outer sheath body having a columnar barrel portion and a barrel-portion end face arranged on one end face of the barrel portion, in which the sensor element is arranged in the barrel portion of the outer sheath body such that the pair of measurement electrodes is exposed from an open frontal area of the barrel-portion end face. | 10-20-2011 |
20110252866 | PARTICULATE MATTER DETECTING DEVICE - A particulate matter detecting device includes a sensor element having a measurement electrode and a heater electrode provided on one end portion of a plate-like element substrate, a cylindrical lead terminal cover member having the sensor element inserted into a penetration portion that penetrates in an axial direction thereof so that the sensor element is held inside a detecting device external cylinder, and the detecting device external cylinder. The penetration portion includes a first penetration portion having a size corresponding to that of a cross section of the sensor element, and a second penetration portion with a larger cross section perpendicular to the penetration direction than that of the first penetration portion. An electrical insulating sealant is filled in a gap between the second penetration portion and the sensor element inserted into the second penetration portion so that the sensor element and the lead terminal cover member are fixed. | 10-20-2011 |

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 |
