20080248238 | BONDING MATERIAL, PROCESS FOR PRODUCING THE SAME, AND HONEYCOMB STRUCTURE MADE WITH THE SAME - There is provided bonding material having a Young's Modulus after hardening of not less than 20% of articles to be bonded, and an average linear coefficient of thermal expansion after hardening of not more than 70% of the articles to be bonded. This bonding material can suppress deformation of a honeycomb segment due to thermal stress to be generated by a bonding material layer and can suitably be used at the time of manufacturing exhaust gas trapping filters capable of reducing the generation of defects such as a crack, and above all, a diesel particulate filter (DPF) for trapping particulate matter (particulates) in exhaust gas from the diesel engine. | 10-09-2008 |
20090022972 | METAL PHOSPHATE COMPOSITE AND DENSE MATERIAL COMPRISED OF THE SAME - A metal phosphate composite having a composition represented by the formula M1 | 01-22-2009 |
20090041975 | BONDED ELEMENT, HONEYCOMB SEGMENT BONDED ELEMENT, AND HONEYCOMB STRUCTURE USING THE SAME - There is disclosed a bonded element manufactured from a bonding material composition being capable of contributing to the lowering of thermal expansion of a bonding material layer sufficiently to relax any thermal stress generated in a honeycomb structure and largely inhibiting the cracking of the resultant honeycomb structure as well. In a bonded element in which two or more objects to be bonded are integrated via a bonding material layer, the bonding material layer having a Young's modulus of 20% or less of that of the objects to be bonded and having an average linear thermal expansion coefficient of 70% or less of that of the objects to be bonded, the bonding material layer being prepared from a bonding material composition composed mainly of fillers and a matrix in which fillers having an average linear thermal expansion coefficient of 2.0×10 | 02-12-2009 |
20110083490 | GAS SENSOR - A gas sensor includes an internal space, diffusion control part, pumping cell, and measuring cell. The diffusion control part communicates with the internal space and has a slit-like shape with a smaller thickness than that of the internal space. The pumping cell pumps out oxygen from the internal space when voltage is applied between a first electrode formed on a surface of the internal space and a second electrode formed outside the internal space. The measuring cell measures a current flowing between a third and fourth electrodes when a voltage is applied between the third and fourth electrodes. The third electrode is formed in the diffusion control part, and can reduce an oxide gas component in a predetermined gas component to which a predetermined diffusion resistance has been applied by the diffusion control part. The fourth electrode is formed in a part different from the diffusion control part. | 04-14-2011 |
20110147214 | GAS SENSOR AND METHOD FOR MANUFACTURING SENSOR ELEMENT - A gas sensor capable of a high-accuracy measurement which is realized by a high responsiveness and a strength that prevents a sensor element from being damaged by a stress occurring in assemblage and usage. This gas sensor includes a sensor element formed of an oxygen-ion conductive solid electrolyte as a main component, and the sensor element includes: an internal space to which a measurement gas is introduced from the outside; a first electrode formed on a surface of the internal space; a second electrode formed in a space different from the internal space; and a pumping cell including the first and second electrodes. The pumping cell is operable to pump out oxygen existing in the internal space when a predetermined voltage is applied to between the first and second electrodes. The thickness of the internal space is 50 μm or more and 180 μm or less. | 06-23-2011 |
