  • Publication number: 20100208868
    Abstract: In one embodiment of the present invention, a curvature distribution crystal lens of the present invention is obtained via press-molding. In the case of a Ge single crystal plate, a temperature for the press-molding is in a range 1° C. to 120° C. lower than a melting point. In the case of a Si single crystal plate, a temperature for the press-molding is in a range 1° C. to 200° C. lower than a melting point. The curvature distribution crystal lens has a crystal lattice plane forming a 1D cylindrically curved surface or a 1D logarithmically curved surface whose valley is in a direction perpendicular to a direction having a maximum curvature, the direction having the maximum curvature being within 30° from a [001] or [1-10] direction in a (110) plane. As a result, it is possible to make an integrated reflection intensity uniform and to make a half-value width uniform in a wide range.

    Abstract: The present invention realizes (i) a gas flow measuring device which can measure a gas flow of a low-boiling gas in a mixed gas including two types of gasses having different boiling points, and (ii) a method of measuring a gas flow easily but highly precisely, using the gas flow measuring device. The gas flow measuring device includes a condensing tank for condensing a mixed gas in which two types of gasses having different boiling points are mixed with each other, and a flow meter for measuring the flow of the mixed gas. After condensing the mixed gas in the condensing tank so as to cause the gas flow of the high-boiling gas to be known, the flow is measured using the flow meter so that the gas flow of the low-boiling gas is worked out.
