20100229371 | TUBULAR STRUCTURE FOR FIXING PARTICULATE MATTER DETECTION DEVICE - A tubular structure for fixing particulate matter detection device | 09-16-2010 |
20100229627 | PROTECTIVE EQUIPMENT FOR PARTICULATE MATTER DETECTION DEVICE - A protective equipment | 09-16-2010 |
20100229629 | PARTICULATE MATTER DETECTION DEVICE - A particulate matter detection device | 09-16-2010 |
20100242441 | DEVICES FOR DETECTING ACCUMULATION AMOUNT OF PARTICULATES - It is provided a device for detecting an accumulation amount of particulates. The device has a filter for trapping particulates from a gas containing the particulates, a container | 09-30-2010 |
20100242442 | DEVICES FOR DETECTING ACCUMULATION AMOUNT OF PARTICULATES - A device for detecting particulates includes: a filter; a filter container; an upstream pipe; a downstream pipe; an upstream detecting unit; and a downstream detecting unit. The upstream detecting unit has a branch flow route for receiving gas from the upstream pipe, a trapping portion, a transmitting portion for transmitting an electromagnetic wave to the trapping portion, and a receiving portion for receiving an electromagnetic wave from the trapping portion. The downstream detecting unit has a branch flow route for receiving gas from the downstream pipe, a trapping portion, a transmitting portion for transmitting an electromagnetic wave to the trapping portion, and a receiving portion for receiving an electromagnetic wave from the trapping portion. The amount of the particulates trapped in the filter is detected based on a difference between detection values of the mass of the particulates trapped in the upstream and downstream trapping portions. | 09-30-2010 |

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 |
