    • A solid-state imaging device includes: a plurality of pixels which are arranged in a matrix; a sequential scanning device that selects each row of pixels; and an analog-to-digital conversion unit having a first analog-to-digital converter that is connected to a vertical signal line to which a pixel signal is supplied from the pixel and performs a first bit-length analog-to-digital conversion on an output signal from the vertical signal line or a pixel output signal obtained by sampling the output signal, and a second analog-to-digital converter that, when the first analog-to-digital converter completes the conversion operation, subtracts an analog signal corresponding to the first bit-length from the pixel output signal and then performs a second bit-length analog-to-digital conversion.

    • To control information obtained from inside of a living body with higher precision as compared to that in the conventional technology by controlling a ratio of intensities of light, directed to a trial body, in a plurality of wavelength ranges different in peak wavelength from each other, a measurement error included in information obtained from the living body can be controlled by changing a ratio of intensity of the light in the first wavelength range against that of the light in the second wavelength range. When intensity of irradiated light is limited from the viewpoint of safety to the trial subject, keeping a ratio of the light irradiated to the trial body in the first wavelength range against that of the light in the second wavelength range under a prespecified value and also changing the ratio of irradiated light intensities under the prespecified value.

    • To provide an exhaust emission control device of an internal combustion engine able to well atomize a reducing agent and ensure supply of combustion air. Since a controller of the exhaust emission control device also controls a nozzle opening degree of a variable geometry turbocharger for purpose of spraying a urea water, even in the state where the engine works in a low load range of T1 to T2 where supercharging pressure normally can not be increased, supercharging pressure P suitable to atomization of the urea water can be obtained by controlling the nozzle opening degree of the variable geometry turbocharger to be closer to a closing side compared to the conventional art (shown by the chain double-dashed line), while the urea water can be securely atomized by a part of the supercharged air. Further, by increasing the supercharging pressure up to the value P, combustion air supplied to the engine is increased, therefore favorable combustion can be realized, and generation of particulates and exhaust of unburned fuel can be reduced.
    • 提供能够充分雾化还原剂并确保供给燃烧空气的内燃机的废气排放控制装置。 由于废气排放控制装置的控制器也控制用于喷射尿素水的可变几何涡轮增压器的喷嘴开度,即使在发动机在T1至T2的低负载范围内工作的状态下,其中增压压力通常可以 通过将可变几何形状的涡轮增压器的喷嘴开度控制为比传统技术(由双点划线所示)更靠近闭合侧,可以获得适合于尿素水雾化的增压压力P, 而尿素水可被一部分增压空气牢固地雾化。 此外,通过将增压压力提高到P值,供给到发动机的燃烧空气增加,因此能够实现良好的燃烧,能够降低未燃燃料的微粒和废气的产生。
