    摘要: The present invention relates to an illuminant, etc., having a high response speed and a high luminous intensity. The illuminant comprises a substrate and a nitride semiconductor layer provided on one surface of the substrate. The nitride semiconductor layer emits fluorescence in response to incidence of electrons. At least part of the emitted fluorescence passes through the substrate, and then exits from the other surface of the substrate. Generation of the fluorescence is caused by incidence of electrons onto a quantum well structure of the nitride semiconductor layer and recombination of pairs of electrons and holes generated due to electron incidence, and the response speed of fluorescence generation is on the order of nanoseconds or less. Also, the luminous intensity of the fluorescence becomes equivalent to that of a conventional P47 fluorescent substance. Namely, the illuminant has a response speed and a luminous intensity that are sufficient for adaptation to scanning electron microscopes and mass spectroscopes.

    摘要: A light-emitting body of rapid speed of response and high light emission intensity, and an electron beam detector, scanning electron microscope and mass spectroscope using this are provided. In the light-emitting body 10 according to the present invention, when fluorescence is emitted by a nitride semiconductor layer 14 formed on one face 12a of a substrate 12 in response to incidence of electrons, at least some of this fluorescence is transmitted through this substrate 12, whereby that fluorescence is emitted from the other face 12b of the substrate. The response speed of this fluorescence is not more than μsec order. Also, the intensity of emission of this fluorescence is almost identical to that of a conventional P47 phosphor. Specifically, with this light-emitting body 10, a response speed and light emission intensity are obtained that are fully satisfactory for application to a scanning electron microscope or mass spectroscope. In addition, a cap layer 16 contributes to improvement in the persistence rate of light emission in the nitride semiconductor layer 14, so, with this light-emitting body 10, not only high-speed response and high light emission intensity are obtained, but also an excellent persistence rate.

    摘要: An intake air flow detecting device is provided to an intake air passage, through which intake air flows into an internal combustion engine. Intake air flow is divided into a main passage and a bypass passage. The detecting device includes a thermal air flowmeter, a bypass flow delay information calculating means, and a response delay compensating means. The thermal air flowmeter includes a detector arranged in the bypass passage for detecting an air flow amount in the intake air passage. The bypass flow delay information calculating means calculates a bypass flow delay information representing delay in variation in a flow amount in the bypass passage with respect to variation in a flow amount in the main passage. The response delay compensating means compensates delay in response of the air flowmeter in accordance with the bypass flow delay information.
