A lighting apparatus of an elevator has a light source element for lighting in the cage, which is provided on the ceiling of an elevator. The light source element composes combination of light sources including at least one first light source to emit a first lighting color, and at least one second light source to emit a second lighting color different from the first lighting color. The light sources with different lighting colors are simultaneously used, providing various color tones.

The measurement sensitivity is improved by suppressing the surrounding temperature influence as much as possible, while realizing scale reduction, and by enlarging the detection signal, while reducing the production errors in enclosing a reference gas. Provided is a thermal conductivity sensor that detects thermal conductivity of a sample gas by using a Wheatstone Bridge circuit constructed in such a manner that measurement resistors that are brought into contact with the sample gas are disposed on a first side, and reference resistors that are brought into contact with a reference gas are disposed on a second side, and comparing the potential difference between connection points of the reference resistors and the measurement resistors. The measurement resistors disposed on the first side are assembled in one measurement space, and the reference resistors disposed on the second side are assembled in one reference space.

This invention relates to a multi-component absorbance monitor, and the object is to provide a general-purpose and highly accurate compact absorbance monitor. Disclosed is an absorbance monitor including a light source, a sample cell and a plurality of detectors as elements, wherein a light collecting member is arranged between the light source and one detector, and an inside wall of the light collecting member has a site for guiding a part of light from the light source, that is, a light guiding opening, and light from the light guiding opening enters another detector. Preferably, the light collecting member lies between the light source and the sample cell. Preferably, an optical element used for another detector described above is arranged in the light guiding opening and adjacently to a light path formed by the light collecting member.
