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 |
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 |
20150030510 | HONEYCOMB STRUCTURE - A honeycomb structure of the present invention includes a honeycomb structure body and a pair of electrode member arranged at a side surface of the honeycomb structure body. The honeycomb structure body has an electrical resistivity of 1 to 200 Ωcm, and the respective pair of electrode members is formed into a band-like shape extending in a direction in which the cells extend. In a cross section perpendicular to the cell extending direction, one of the electrode members is arranged opposite to another of the electrode members sandwiching a center of the honeycomb structure body. One or more of slits, which being open to a side surface, are formed at the honeycomb structure body. At least the one slit is formed so as not to intersect with a straight line connecting center portions of the respective pair of electrode members in the cross section perpendicular to the cell extending direction. | 01-29-2015 |
