    • In one embodiment a relief safety valve driving system that supplies a driving gas by use of a relief safety valve driving unit and thereby opens a relief safety valve provided in a main steam system of a nuclear power plant if an accident or a transient state occurs, for protecting a reactor against pressurization, wherein the relief safety valve driving unit opens the relief safety valve by supplying the driving gas to the relief safety valve by one or more auto-depressurization system actuating signals, among auto-depressurization system actuating signals respectively belonging to three safety segments, or by a relief valve functions actuating signal, and closes the relief safety valve without supplying the driving gas thereto when none of the auto-depressurization system actuating signals and the relief valve functions actuating signal is generated.

    • An OCT probe has a sheath to be inserted into a subject; and an optical system within the sheath, for changing the direction of light which propagates from a light source through an optical fiber to irradiate the light onto the subject through a transparent portion of the sheath, and for reflecting the light beam, which is reflected by the subject, to guide the light into the optical fiber. A light output surface, for causing the light to be output from the reflecting surface in a direction obliquely inclined with respect to the inner surface of the sheath, and a reflected light sheath entrance preventing portion, for preventing light reflected by the inner surface of the sheath from entering the optical fiber, are provided in the optical system. The reflected light sheath entrance preventing portion may be formed by providing a cut planar surface portion on the lens.
    • OCT探针具有插入受试者的护套; 以及在护套内的光学系统,用于改变从光源通过光纤传播的光的方向,以通过护套的透明部分将光照射到被摄体上,并且用于反射由光束反射的光束 将光线引导到光纤中。 一个光输出表面,用于使光从相对于护套的内表面倾斜倾斜的方向从反射表面输出,反射光线入口防止部分,用于防止光的内表面反射的光 护套进入光纤,设置在光学系统中。 可以通过在透镜上设置切割的平坦表面部分来形成反射光线入射防止部分。
