    Abstract: A X-ray detector having enhanced X-ray sensitivity, which enables dual energy imaging having high diagnostic performance. This X-ray detector includes: scintillator elements which are partitioned by light blocking walls and which convert low-energy X-rays to light; and scintillator elements which are partitioned by light blocking walls and which convert high-energy X-rays to light. When seen from the direction of incidence of the X-rays, the positional pattern of the light blocking walls and that of the light blocking walls are configured so as not to be in alignment with each other. Accordingly, the X-rays incident on the X-ray detector are converted to light by at least either one of the scintillator elements and are finally outputted as X-ray detection signals.

  • Patent number: 10180109
    Abstract: An internal combustion engine 100 comprises an air-fuel ratio control device. The air-fuel ratio control device controls the amount of fuel fed to the combustion chamber by feedback control so that the air-fuel ratio detected by the upstream side air-fuel ratio sensor matches the target air-fuel ratio when a blow-through amount of air blown from the intake passage through a cylinder to the exhaust passage due to an occurrence of valve overlap is a reference blow-through amount or less. The air-fuel ratio control device sets the target air-fuel ratio of the inflowing exhaust gas based on the air-fuel ratio detected by the downstream side air-fuel ratio sensor and, without performing the feedback control, feeds the amount of fuel calculated from the target air-fuel ratio to the combustion chamber when the blow-through amount is greater than the reference blow-through amount.

  • Patent number: 10100763
    Abstract: In a control apparatus for use an internal combustion engine in which warming-up time air fuel ratio control is executed, the air fuel ratio of the exhaust gas flowing into the three-way catalyst is changed to an air fuel ratio higher by the predetermined amount, by using as a trigger the timing at which a measured value of an air fuel ratio sensor indicates a rich air fuel ratio. In addition, when the timing at which the measured value of the air fuel ratio sensor indicates the rich air fuel ratio is earlier than a reference timing, the starting-time-rich-air-fuel-ratio in the next and following warming-up time air fuel ratio control is corrected to an air fuel ratio which is higher than that in the current warming-up time air fuel ratio control.
