20080285026 | OPTICAL CHARACTERISTIC MEASURING APPARATUS AND MEASURING METHOD USING LIGHT REFLECTED FROM OBJECT TO BE MEASURED - A measurement-purpose light source generates a measurement light used for measuring an optical characteristic of an object to be measured, and the measurement light includes a component in a wavelength range for measurement of the optical characteristic of the object. An observation-purpose light source generates an observation light used for focusing on the object to be measured and checking a position of measurement. The observation light is selected such that the observation light includes a component that can be reflected from the object to be measured. The measurement light and the observation light are thus applied independently to the object to be measured, through a common objective lens, and accordingly improvement of the precision in measurement of the optical characteristic and facilitation of focusing on the object to be measured are achieved simultaneously. | 11-20-2008 |
20100091280 | OPTICAL CHARACTERISTIC MEASUREMENT DEVICE AND OPTICAL CHARACTERISTIC MEASUREMENT METHOD SUITABLE FOR SPECTRUM MEASUREMENT - A processing unit obtains a first spectrum detected in a first detection area and a first signal intensity detected in a second detection area after the light entering the housing is cut off, and then calculates a first correction spectrum by subtracting a first correction value calculated based on the first signal intensity from each component value of the first spectrum. The processing unit obtains a second spectrum detected in the first detection area and a second signal intensity detected in the second detection area while a cut-off portion is opened, and then calculates a second correction spectrum by subtracting a second correction value calculated based on the second signal intensity from each component value of the second spectrum. The processing unit calculates an output spectrum representing a measurement result by subtracting a corresponding component value of the first correction spectrum from each component value of the second correction spectrum. | 04-15-2010 |
20120075628 | OPTICAL CHARACTERISTIC MEASUREMENT DEVICE AND OPTICAL CHARACTERISTIC MEASUREMENT METHOD SUITABLE FOR SPECTRUM MEASUREMENT - An optical characteristic measurement device includes a photodetector and a processor. The photodetector has a detection surface greater than a light incident surface receiving light from a spectrometer. The processor is configured to obtain a measurement spectrum detected in a first detection area corresponding to the light incident surface and a signal intensity detected in a second detection area different from the light incident surface, correct a pattern prepared in advance and exhibiting a noise characteristic of the photodetector based on the signal intensity to calculate a first correction spectrum, subtract a correction value calculated based on the signal intensity from each component value of the measurement spectrum to calculate a second correction spectrum, and subtract each component value of the first correction spectrum from a corresponding component value of the second correction spectrum to calculate an output spectrum. | 03-29-2012 |

20160107239 | METHOD FOR MANUFACTURING NANOCOMPOSITE THERMOELECTRIC CONVERSION MATERIAL - This invention provides a method for manufacturing a nanocomposite thermoelectric conversion material in which phonon-scattering particles having a specific shape are dispersed, reducing thermal conductivity and increasing thermoelectric conversion performance. Said method for manufacturing a nanocomposite thermoelectric conversion material, in which oxide phonon-scattering particles are dispersed within the matrix of a thermoelectric conversion material, is characterized by including the following stages: a first stage in which, in a solution, the reduction of a salt is used to precipitate out/grow nanoparticles consisting of elements constituting a thermoelectric conversion material, the polymerization of a precursor is used to precipitate out/grow nanoparticles consisting of an oxide constituting phonon-scattering particles, and a mixture of said nanoparticles is collected; and a second stage in which a hydrothermal treatment is used to alloy said mixture into composite nanoparticles, which are then sintered. This method for manufacturing a nanocomposite thermoelectric conversion material is also characterized in that in the aforementioned first stage, nanoparticles consisting of a first group of elements that constitute the thermoelectric conversion material are precipitated out or grown before nanoparticles consisting of oxides of a second group of elements that constitute the phonon-scattering particles. | 04-21-2016 |
