    摘要: This optical sensor device includes a first light receiving portion having sensitivity to ultraviolet light, a first sealing portion covering the first light receiving portion, a second light receiving portion having sensitivity to ultraviolet light, and a second sealing portion which covers the second light receiving portion. At least one of the first sealing portion and the second sealing portion is configured to transmit at least part of a ultraviolet light wavelength band, the first sealing portion is formed from one or more resin layers and has transmission spectral characteristics that a first wavelength is set as a lower limit value of a transmission wavelength band, and the second sealing portion is formed from one or more resin layers and has transmission spectral characteristics that a second wavelength different from the first wavelength is set as a lower limit value of the transmission wavelength band.

    摘要: The present invention relates to a Ni-based heat-resistant alloy including Ir: 5.0 mass % or more and 50.0 mass % or less, Al: 1.0 mass % or more and 8.0 mass % or less, W: 5.0 mass % or more and 25.0 mass % or less, and balance Ni, having an L12-structured γ′ phase present in the matrix, and including at least one of Ru: 0.8 mass % or more and 5.0 mass % or less and Re: 0.8 mass % or more and 5.0 mass % or less. This Ni-based heat-resistant alloy has improved toughness over a conventional Ni-based heat-resistant alloy based on a Ni—Ir—Al—W-based alloy, and is also excellent in ambient-temperature strength.
