摘要： In order to read out information even from an optical recording medium having birefringence, of a diffracting element comprising an optical material forming a diffraction grating 21 having a cross-sectional shape of projections and recesses, and another optical material 22 filled at least in the recesses of the diffraction grating 21, at least one of the above two types of optical materials 21 and 22 shows birefringence, and the other optical material 22 has a refractive index which is different from both the ordinary refractive index and the extraordinary refractive index of said one optical material 21 showing birefringence. Further, in order to obtain a diffracting element of polarization type having a high diffraction efficiency and a uniform distribution in the plane, an alignment treatment film 11 is formed on one of two substrates 2 facing each other, spacers 12 to hold the space constant, and liquid crystal to be a thin film 1 of polymer liquid crystal, are sandwiched between the substrates 2 facing each other, the liquid crystal is aligned and cured by irradiation with light to obtain the thin film 1 of polymer liquid crystal, then one substrate is taken off, a grating having a cross-sectional shape of projections and recesses is formed on the thin film 1 of polymer liquid crystal, and the projections and recesses are filled with an isotropic medium.

摘要： A medical waste disposal apparatus for heating waste includes a hydrodynamic exhaust scrubber in which water is sprinkled in an atomized or spouted state into a circulation passage as the gaseous pyrolytic product and the steam flow through the passage, so that the product and the steam are dissolved in the water. The product and the steam are thus collected and removed.
