    摘要: A measurement unit used in an analyzing apparatus for measuring concentrations of component gases in a sample gas comprises a light emitting unit configured to emit a measurement light to the sample gas, a light receiving unit configured to receive the measurement light on a light receiving plane, a purge air introducing unit configured to introduce a purge air into a vicinity of at least one of the light emitting unit and the light receiving unit, and a condensing lens arranged in an optical path of the measurement light from the light emitting unit to the light receiving unit, the condensing lens being configured to condense the measurement light within the light receiving plane of the light receiving unit, a propagation path of the measurement light being varied by a thermal lens effect caused by a temperature difference between the sample gas and the purge air.

    摘要: A probe for gas analysis is provided in a pipe through which sample gas flows. The probe includes a tubular member and one or more sample gas inflow portions. The tubular member is disposed to cross a flow of the sample gas, and includes a measurement field to which the sample gas is introduced. The one or more sample gas inflow portions are provided in the tubular member. The sample gas flows around, and flows into the measurement field through the one or more sample gas inflow portions.

    摘要: An air-driven shutter device is used in an optical analyzer. The optical analyzer includes a measurement field to which a sample is supplied, a light-emitting unit measurement field for emitting measuring light to the sample, a light-receptive unit for receiving the measuring light that has passed through the sample, and a purge air supplying unit for supplying purge air. The air-driven shutter device includes a shutter and a shutter opening and closing mechanism. The shutter is disposed between the light-emitting unit and/or the light-receptive unit and the measurement field. The shutter opening and closing mechanism keeps the shutter open with pressure of the gas supplied from the purge air supplying unit, and closes the shutter when the pressure of the gas supplied from the purge air supplying unit becomes lower than a predetermined level.

    摘要: A polymeric liquid crystal composition includes a polymer mesomorphic compound having an asymmetric carbon atom and a low-molecular weight mesomorphic compound. The composition can be easily formed into a film of a large area, exhibits a response speed which is not substantially different from that of the low-molecular weight mesomorphic compound alone and stably retains alignment resistant to pressure or heat impact. Such a good alignment is especially obtained when the polymeric liquid crystal composition is incorporated in a liquid crystal device by being disposed between a pair of substrates preferably having an alignment face provided with an orientation characteristic for aligning the molecular axis of the liquid crystal composition in one direction. It is suitable that the polymer mesomorphic compound is optically active and has a helical rotation direction opposite to that of the low-molecular weight mesomorphic compound.
