  • Publication number: 20210356253
    Abstract: An oxide layer thickness measurement device according to the present invention stores, for each of layer thickness measurement sub-ranges constituting a layer thickness measurement range, layer thickness conversion information representing a correlation between a layer thickness and an emissivity where a ratio of a change in the emissivity to a change in the layer thickness in the layer thickness measurement sub-range falls within a set extent. Emitting light luminances of a surface of a steel sheet are measured at respective measurement wavelengths different from each other, and a temperature of the surface of the steel sheet is measured to thereby calculate the emissivity at each of the measurement wavelengths.

  • Patent number: 8952338
    Abstract: The present invention provides a crystalline quality evaluation apparatus (1) and a crystalline quality evaluation method for thin-film semiconductors, which are designed to evaluate crystalline quality of a sample (2) of a thin-film semiconductor (2a) by emitting excitation light and an electromagnetic wave to irradiate a measurement site of the sample (2), and detecting an intensity of a reflected electromagnetic wave from the sample (2). In the present invention, the thin-film semiconductor (2a) of the sample (2) is formed on an electrically conductive film (2b), and a dielectric (3) transparent to the excitation light is additionally disposed between the sample (2) and a waveguide (13) for emitting the electromagnetic wave therefrom.

  • Patent number: 8939090
    Abstract: In a guided vehicle of air spring suspension for running along exclusive guideways, decreasing of center distance of the left and right air spring to mount air springs of increased dimension and increased load carrying capacity, which decreasing of the center distance induces decrease in rolling stiffness of the vehicle resulting in deteriorated ride quality and also induces difficulty in adjusting vehicle height resulting in spending long time in height adjusting operation, will not be required even when load carrying capacity of air springs is required to be increased in order to comply with increased vehicle load. A plurality of air spring elements are mounted tandem along the longitudinal direction of the vehicle with the air spring elements connected with each other so that air pressure thereof is always equal.

  • Publication number: 20120203473
    Abstract: In a semiconductor carrier lifetime measuring apparatus A1 of the present invention, at least two types of light having mutually different wavelengths are irradiated onto a semiconductor X to be measured, a predetermined measurement wave is irradiated onto the semiconductor X to be measured, a reflected wave of the measurement wave that has been reflected by the semiconductor X to be measured or a transmitted wave of the measurement wave that has transmitted through the semiconductor X to be measured is detected, and the carrier lifetime in the semiconductor X to be measured is obtained based on the detection results so as to minimize the error. Accordingly, the semiconductor carrier lifetime measuring apparatus A1 configured as described above can more accurately measure the carrier lifetime.

  • Patent number: 8006628
    Abstract: An emergency staircase includes a plurality of step forming members that are housed in a casing. A podium and a railing are fitted to the casing so that the podium and the railing can be unfolded against the casing. Each of the step forming members includes a pair of guiding parts which are arranged in parallel, and a step plate that is sandwiched between the guiding parts of each pair and fastened to each of the guiding parts, so that left and right pairs of resulting squarish U-shapes face each other. Inner guiding parts and outer guiding parts are mutually of a similar configuration, so that each inner one is relatively smaller than each outer one by the thickness of the part. The protrusions act as sliding contacts between adjacent guiding parts.
