  • Patent number: 10871117
    Abstract: After an engine is started, an ECU performs first regeneration processing of a PM sensor through heating by a heater and, after the first regeneration processing, applies a voltage continuously to detection electrodes for a predetermined voltage application period. The ECU causes PM to adhere to an insulating substrate due to the voltage application and, at a time point after the predetermined time period has elapsed, determines the amount of PM that is adhering to the insulating substrate. When a predetermined condition is satisfied outside the voltage application period, the ECU determines whether the amount of adhering PM on the insulating substrate is equal to or greater than an excess determination threshold value. If the amount of adhering PM is determined to be equal to or greater than the excess determination threshold value, the ECU performs second regeneration processing of the PM sensor, through heating by the heater.

  • Patent number: 10809178
    Abstract: An analysis device includes a turntable, an optical pickup, and a controller. The turntable holds a disc for specimen analysis having a reaction region on which fine particles binding to substances to be detected are captured per track. The optical pickup emits laser light to the reaction region, receives a reflected light from the reaction region, and generates a reception level signal of the light. The controller sequentially generates a plurality of measurement gate signals per track for counting the number of the fine particles captured on the reaction region, counts the number of the fine particles per measurement gate signal from the reception level signal, compares measurement results obtained in positions having a symmetric relation with each other in the reaction region, and defines a measurement-result-correction target region for correcting the number of the fine particles.

  • Patent number: 10794811
    Abstract: An apparatus which detects particulate matter is provided. This apparatus estimates a volume of water inside an exhaust passage using estimation sections. When an estimated volume of water is larger than a water drainage threshold, an element portion is heated using a heater by the first temperature range controller, in a temperature range which resists water-induced cracking independent of a volume of water droplets. If the estimated volume of water is less than a water drainage threshold, the water drainage determination section determines that the water drainage of the exhaust passage is completed. Additionally, if it is estimated that the water drainage is completed, the element portion is heated by a second temperature controller at temperature lower than a starting temperature of combustion of particulate matter and in order to repel water adhered onto the element portion in a water-repellent temperature range for a predetermined period.
