    摘要: This invention provides an apparatus for measuring ozone in which interference effects of SO.sub.2 are intended to be reduced. This invention comprises a reference gas line for generating reference gas with ozone removed by allowing the sample gas to pass through the ozone decomposer with silver wool used as a catalyst, a sample gas line for introducing the sample gas as it is, an ozone analyzer to which the reference gas line and the sample gas line are connected via a selector valve and which measures the ozone component in the sample gas by introducing the reference gas and the sample gas alternately at specified intervals, and a temperature controller installed to the ozone decomposer for setting the catalyst reaction temperature to a range from 100 to 130.degree. C.

    摘要: A memory medium includes a memory layer of a polymer liquid crystal and a reflection layer disposed on a substrate. A record part having a different refractive index from that of a non-record part is formed in the memory layer so that the record part and the non-record part have a difference in optical thickness of the memory layer. In a reproduction step, the memory medium is irradiated with a reproduction beam of coherent light so that the reproduction beam is transmitted through the memory layer, reflected at the reflection layer and re-transmitted through the memory layer, during which the reproduction beam is subjected to interferential diffraction due to the optical thickness difference between the record part and the non-record part to allow readout of the recorded data.
