  • Patent number: 10578032
    Abstract: An electronic control unit of an internal combustion engine is configured to control the fuel injection valve and to control a spark plug if necessary such that fuel is combusted by pre-mixture compression ignition combustion or flame propagation combustion. The electronic control unit is configured to perform homogeneous combustion in a flame ignition operation range when switching failure has not occurred, the homogeneous combustion being combustion in which fuel homogeneously diffused into the combustion chamber is ignited using the spark plug and is combusted by flame propagation combustion. The electronic control unit is configured to perform spray-guided stratified combustion in a second operation range when the switching failure has occurred, the spray-guided stratified combustion being combustion in which fuel in the fuel injection path is ignited using the spark plug and is combusted by the flame propagation combustion.

  • Patent number: 10022102
    Abstract: In an X-ray imaging apparatus, a detection panel has monitor pixels for monitoring X-rays. A signal processor samples a dose signal of a dose per unit time of X-rays according to an output of the monitor pixels. A start detector checks whether irradiation of X-rays is started according to a result of comparison between the dose signal and a start threshold. An AEC device acquires cumulative dose from a start time of the start of irradiation of X-rays until acquisition time after a predetermined time according to the dose signal. According to the cumulative dose, a predicted time point of a reach of the cumulative dose to a target dose is estimated. A stop signal is transmitted to a radiation source controller at the predicted time point, to stop the irradiation of X-rays.

  • Patent number: 9995199
    Abstract: An internal combustion engine has a water-cooled intercooler cooling intake air turbocharged by a turbocharger. The intercooler has an HT intercooler into which HT cooling water passing through a cylinder block is introduced and an LT intercooler into which LT cooling water lower in temperature than the HT cooling water is introduced and the LT intercooler is arranged to abut against an intake downstream side of the HT intercooler. A target LT temperature is set to a high temperature-side target value in a case where a temperature of the HT cooling water flowing into the HT intercooler is lower than a target HT temperature correlated with warm-up completion and the target LT temperature is set to a low temperature-side target value in a case where the temperature of the HT cooling water is equal to or higher than the target HT temperature.

  • Patent number: 9952335
    Abstract: The present invention provides a radiation detector, a radiographic imaging device and a radiographic imaging system that may detect radiation with high precision. Namely, in the radiation detector, radiation detection pixels include detection TFTs, and light that has been converted from radiation is illuminated directly from a scintillator onto the detection TFTs. Accordingly, leak current occurs in semiconductor active layers of the detection TFTs corresponding to the amount (intensity) of the illuminated light, and the leak current flows in to signal lines. Accordingly, radiation may be detected by monitoring the leak current, and enables timings, such as the start of irradiation of radiation, to be detected.
