Abstract: A system for calibrating a moisture sensor encompasses a processing unit (341). The processing unit (341) includes a reference data obtaining LCKT (345), a subject data obtaining LCKT (346) and a relationship calculating LCKT (347). The reference data obtaining LCKT (345) obtains reference data, after injecting water-vapor with known concentrations into an analyzer. The subject data obtaining LCKT (346) measures subject data indicating temporal variation of output-responses of a subject sensor element of the analyzer under test. The relationship calculating LCKT (347) compares the subject data with the reference data, and calculates relationships between the output-responses of the subject sensor element and the known concentrations.

Abstract: An optical testing apparatus is used in testing an optical measuring instrument. The optical measuring instrument provides an incident light pulse from a light source to an incident object and receives a reflected light pulse as a result of reflection of the incident light pulse at the incident object. The optical testing apparatus includes two or more testing light sources, two or more optical penetration members, and a wave multiplexing section. The two or more testing light sources each output a testing light pulse. The two or more optical penetration members each have an optical penetration region and receive the testing light pulse from each of the two or more testing light sources for penetration through the optical penetration region. The wave multiplexing section multiplexes the testing light pulses penetrating through the two or more optical penetration members for provision to the optical measuring instrument.

Abstract: An optical testing device for use in testing an optical measuring instrument provides incident light from a light source to an incident object and receives reflected light due to reflection of the incident light at the incident object. The optical testing device includes an incident light receiving section that receives incident light, and a light signal providing section. The light signal providing section provides a light signal to the incident object after a predetermined delay time since the incident light receiving section has received the incident light. A reflected light signal due to reflection of the light signal at the incident object is provided to the optical measuring instrument. The delay time is approximately equal to the time between emission of the incident light from the light source and reception of the reflected light by the optical measuring instrument in the case of actually using the optical measuring instrument.

Abstract: An optical testing apparatus is used in testing an optical measuring instrument that provides incident light from a light source to an incident object and receives reflected light of the incident light at the incident object. The apparatus includes an incident light receiving section, a light signal providing section, an imaging section, and an optical axis misalignment deriving section. The incident light receiving section receives incident light. The light signal providing section provides a light signal to an incident object after a predetermined delay time since the incident light receiving section has received the incident light. The imaging section images the incident light. The optical axis misalignment deriving section derives misalignment of the optical axis of the incident light with respect to the incident light receiving section based on misalignment between the incident light receiving section and the imaging section as well as an imaging result with the imaging section.

Abstract: Cooling liquid flowing through cooling-liquid passages cools in heat-transmission manner an inner layer on an inner surface of an impermeable intermediate layer and is directed through a piping to an interface between the intermediate and outer layers, whereby the porous outer layer is cooled by latent heat generated by evaporation of the cooling liquid infiltrated into the porous outer layer.
