    • 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.

    • 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, by 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 by changing the ratio of irradiated light intensities under the prespecified value, a measurement error included in information obtained from the living body can be controlled.

    • The delay of delay circuit 10 is set within a predetermined range, and, in a stop mode, the clock pulses of 1 cycle of clock signal φin when transition is made from the stop mode to the DLL mode are excluded from the object detected by phase detector 20 such that phase difference Δφ′ detected by phase detector 20 is within a prescribed range when said transition is performed. As a result, it is possible to lock the delay of clock signal φdin with respect to clock signal φin at a desired value (e.g., “2π”), and it is possible to prevent locking to an undesired abnormal state.

    • The invention provides optical technique for measuring metabolism in a living body that can further reduce an error in measurement even if distance between irradiation and detection is fixed. The living body is classified into measurement regions and different measuring wavelengths are set according to the classification. For example, the head is classified into four regions of a parietal region, a frontal region, a temporal region and an occipital region and a wavelength according to each tissue is set in a wavelength selecting system. In measurement, wavelengths according to each measurement region are selected by multiple wavelengths-light radiating means. Besides, for a region having large personal difference, premeasurement is made using plural combinations of wavelengths and wavelengths are selected using a calculated error in measurement as a criterion.
