Abstract: PURPOSE:To widen a sample chamber and to reduce the distance between the sample and a photodetector by so arranging a titled meter that divided two luminous fluxes are intersected again at around 90 deg. angle and disposing one photodetector commonly for the two luminous fluxes near the point of intersection thereof. CONSTITUTION:The luminous flux emitted from a spectroscope is divided and the divided luminous fluxes are intersected again at around 90 deg.. One photodetector is disposed commonly for the two luminous fluxes near the point where the two luminous fluxes intersect. For example, the light out from a spectroscope M is divided to two luminous fluxes with a sector mirror S1; the reflected luminous flux is reflected by mirrors m3, m4, and the transmitted luminous flux is reflected by mirrors m1, m2. These two luminous fluxes are intersected orthogonally on the photodetection surface of a photomultiplier P. Further, two sheets of light diffusion plates D, D' are disposed orthogonally in front of the photodetection surface of the photomultiplier P so as to assure the equivalency of the two luminous fluxes.

Abstract: PURPOSE:To perform measurement in the state of good SN ratios by disposing image sensors on a spectrum image plane and setting scanning speeds in such a way that the integrated output thereof is nearly saturated. CONSTITUTION:The light diffracted by the concave diffraction grating G of a spectroscope 1 is imaged on a photodiode array P driven by a sweeping circuit 2. The integrated output thereof is inputted and stored in a control circuit 5 via a preamplifier 3 and an ADC 4. The 2 operations are repeated, whereby the ratio of the output of a photodetector P to the satd. output value of the max. value of the output is calculated and the scanning speed of the circuit 2 is controlled until the max. value attains a satd. value. Next, when the key for measurement start is pushed, the photodetectors P are scanned at a set scanning speed, and the ratio of the time when only the solvent is put into a sample cell C and the output of the time when a sample soln. is set are calculated with a controller 5 and is displayed 6. Thereby, the measurement is performed in the state of good SN ratios.

Abstract: PURPOSE:Not only to increase the accuracy of measurement but to realize a simple and small-sized constitution, by carrying out a scanning of the wavelength with a relative turn secured between the diffraction grid for spectrum of the reflected light of measurement and the detector for the spectrum. CONSTITUTION:The white light reflected from sample 3 enters Rowland concave surface diffraction grid 10 through slit 8 provided on the Rowland circle of grid 10. Grid 10 gives a spectrum to white reflected light into a double or the like compared with the number of photoelectric transducers D1-D18 with a pitch of 1/2 or the like of transducers D1-D18 provided on the Rowland circle with an equal and fixed pitch. On the other hand, a control is given to the rotary movement of cam 14 via CPU21 which controls integrators I1-I18 corresponding to transucers D1-D18. At the same time, a relative turn is given between grid 10 and transducers D1-D18 to give a scanning to the wavelength. As a result, the spectral diffraction corresponding to many wavelengths is measured by a small number of photoelectric transducers or the like. Thus a simple and small-sized spectrum can be obtained with a high resolution and high accuracy.

Abstract: PROBLEM TO BE SOLVED: To calculate depth of hole or step with high precision by eliminating the effect of thickness of resist film during execution of etching.SOLUTION: The light of predetermined wavelength width is radiated to a sample 50, and the light containing interference with the light reflected on a bottom surface of a hole 52 or an upper surface of a substrate 51, and the like is subjected to spectral detection by a spectroscope unit 25. At a data processing part 30, an interference spectrum is obtained that is provided by removing effects or the like of an emission spectrum of a light source 21 from spectral profile, which is then subjected to Fourier transformation to provide a peak interval, for calculating depth of a hole, film thickness, or the like. Since a chopper 103 periodically allows shielding/passing of external reference light that is reflected on an external reference surface 104, a data processing part 30 provides data with external reference light and data with no external reference light. For example, during the period when a resist layer 53 is thick, a depth of hole or the like is calculated based on the data with no external reference light which has higher resolution, but when the resist layer 53 becomes thinner as etching proceeds, a depth of a hole or the like is calculated based on the data with external reference light which is hard to be affected by disturbance.

Abstract: PROBLEM TO BE SOLVED: To provide a vacuum pump with improved temperature determination accuracy, while suppressing increase in cost.
SOLUTION: A nut 42 disposed on a shaft 3 of the vacuum pump has a magnetic body target 81 in which there is Curie temperature within a temperature monitoring range of a rotor 2.

Abstract: PROBLEM TO BE SOLVED: To acquire significant information on a living body in a measurement by using information on an image obtained from a two-dimensional change amount without measuring an absolute amount and to diagnose the state of the tissue of the living body. SOLUTION: In this optical-image measuring apparatus, a living body (a specimen 10) is irradiated with light, light which is emitted from the living body is detected by a two-dimensional detector (an optical detection means 21), and an image is obtained. The optical-image measuring apparatus is constituted in such a way that it is provided with an image measuring means 2 which acquires image data at a plurality of wavelengths in a time-dependent manner and that it is provided with an image computing means 3 which computes an image used to find information on the living body by using a plurality of image data whose measuring wavelengths and measuring times are respectively different. The two-dimensional change amount of the specimen such as the living body or the like is acquired as image data in a plurality of times. The acquired image data at many wavelengths and in the plurality of times are computed. Significant information on the living body in a measurement is obtained. As a value which is related to the information on the living body, an oxyhemoglobin amount or a deoxyhemoglobin amount can be used.
