    • A light source section outputs optical flux having two types of wavelength, which are a short wavelength and a long wavelength, while the intensity is made variable. The optical flux is made incident to a detected surface of a body to be detected at a predetermined incident angle simultaneously or alternatively. Based on a type of optical flux outputted from the light source section and an output from a first light intensity detecting section, at least the intensity of the optical flux having a long wavelength outputted from the light source section is adjusted. The output from the first light intensity detecting section in irradiating the optical flux having a short wavelength is compared with the output from the first light intensity detecting section in irradiating the optical flux having a long wavelength. A signal that appears only in the output from the first light intensity detecting section in irradiating the optical flux having a long wavelength is identified as a detected signal from an internal subject. The intensity of optical flux having a long wavelength is adjusted. A disappearance level near a point where the detected signal from the internal subject disappears is calculated. The first intensity of optical flux having a long wavelength is set to level higher than the disappearance level. Based on the output from the first light intensity detecting section obtained by the optical flux having a long wavelength of the first intensity, a subject inside the body to be detected is measured.
    • 光源部分输出具有短波长和长波长的两种波长的光通量,同时强度可变。 光通量以预定的入射角同时或交替地入射到要检测的身体的检测表面。 基于从光源部输出的光通量和第一光强检测部的输出,至少从光源部输出的具有长波长的光通量的强度被调整。 在照射长波长的光通量时,将照射具有短波长的光束的来自第一光强度检测部的输出与来自第一光强检测部的输出进行比较。 作为来自内部被检体的检测信号,识别仅在来自第一光强检测部的输出中出现的长波长的光束的信号。 调整长波长的光通量的强度。 计算来自内部对象的检测信号消失的点附近的消失水平。 具有长波长的光通量的第一强度被设置为高于消失水平的水平。 基于通过具有第一强度的长波长的光通量获得的来自第一光强检测部的输出,测量被检体内的被检体。

    • Only suspension type superheaters (52) and (53) are disposed in an outlet of a furnace. These superheaters have heat transfer areas which are so dimensioned that an exhaust gas temperature at downstream of the superheaters is 1000.degree. C. to 1100.degree. C. when the boiler is under a maximum load. An exhaust gas passage downstream of the superheaters (52) and (53) is divided into sub passages along a flow of an exhaust gas, and a damper is disposed in an outlet of each of the sub passages for adjusting a flow rate of the exhaust gas flowing through the respective sub passages. A traverse type reheater (41) is disposed in the sub passage. Since a difference between a temperature (1000.degree. C. to 1100.degree. C.) of the exhaust gas flowing around the reheater (41) and a temperature of steam flowing through the reheater (41) is large, heat exchange can be performed with a high efficiency even through a small heat transfer area. Accordingly, this configuration makes it possible to prevent a heat transfer area of the reheater (41), or overall dimensions of a boiler from being increased.
