    Abstract: PROBLEM TO BE SOLVED: To measure a large-sized sample in a horizontally placed state. SOLUTION: Luminous flux S on a sample side is incident on the undersurface of a sample 21, in an almost vertical direction and the light transmitted through the sample upwardly is refracted by a reflecting mirror M1 to be sent to an integrating sphere 24 equipped with a detector. A luminous flux R on the reference side incident, in parallel with the luminous flux S on the sample side, is refracted by reflecting mirrors M2-M4 so as to bypass the sample 21 to be introduced into the integrating sphere 24. Accordingly, it is unnecessary to prepare a holder matched with the sample 21 in size or shape, and a measuring position can be freely changed by shifting the position of the sample. When a conventional standard sample chamber 11 is utilized, movable reflecting mirrors 22, 23 are inserted in a optical path and luminous flux advancing on a horizontal surface in parallel by reflectingt mirrors M5-M7 may be used.

    Abstract: PROBLEM TO BE SOLVED: To facilitate a mounting work, to occupy no wide space, and besides to detect in such a manner that adhesion of frost is distinguished from that of ice. SOLUTION: A base sheet 4 having a heat generating resistor 2 and a thermistor 3 is arranged in the vicinity of a heat-exchanger. When temperature detected by the thermistor 3 is lower than a freezing temperature, the heat generating resistor 2 is caused to generate heat in a specified time ratio until temperature measured by the thermistor 3 is increased by a given value. When an increase time required for the increase of the temperature is higher than a given ice boundary value, it is decided that a freezing state is produced. When the increase time is lower than the ice boundary value and higher than a given frost boundary value, it is decided that a frosting state is produced. When the increase time is lower than the frost boundary value, it is decided that neither frost nor ice is adhered.

    Abstract: PURPOSE:To reduce the opening area of an incident window, to reduce the opening ratio of an integrating sphere and to make it possible to measure the diffused reflection only based on the diffused reflection component by providing the constitution wherein luminous fluxes are cast into two reflection measuring windows at an incident angle 0 and a specified incident angle. CONSTITUTION:A main body 1 of an integrating sphere has two reflection measuring windows, wherein a sample 2 whose reflection is measured or a standard sample 2 is arranged. Incident windows A and B, through which measuring luminous flux or reference luminous flux is cast, are provided in correspondence with the reflection measuring windows. The window A is set so that the incident luminous flux 3 is cast on the sample at the specified incident angle and the reflected luminous flux 4 does not return to the incident window again. The incident window at the side A has the opening area of the size, which can sufficiently pass only the incident luminous flux, because the luminous flux 3 has the specified incident angle and the entire reflected luminous flux from the corresponding sample is supplemented with the inner wall of the integrating sphere.

    Abstract: PURPOSE:To cover a wide wavelength region by setting different wavelengths by one diffraction grating without using a change-over mechanism by using a diffraction grating wherein the angles of inclination to the grating surfaces of the slopes of a grating groove on both sides thereof are made different from each other. CONSTITUTION:A diffraction grating G is mounted to the upper part of a shaft rotatable around a point 0 and a sign bar S is provided to the shaft so as to protrude horizontally therefrom. A feed screw T is rotated by a drive device D using a pulse motor and the quantity of rotation of the screw T is converted to a wavelength to be displayed. The nut NA with which the sphere provided to the leading end of the sign bar S is brought into contact is threaded with the feed screw T. When the sign bar S is vertical to the grating surface of the diffraction grating G and present in an ON-direction, the wavelength of diffracted light is 0 and becomes the starting position of a spectroscope. Since the sign bar S is energized in a clockwise direction by a spring Sp, said sign bar S is always elastically in contact with the nut NA and revolved in the clockwise direction as the nut is moved to the right. According to the belonging wavelength region of a measured wavelength, either one of +1st order diffracted light and -1st order diffracted light is utilized.

    Abstract: PROBLEM TO BE SOLVED: To provide a double beam spectrophotometer capable of measuring large-scale samples in a horizontally-installed situation.
    SOLUTION: The sample-side light flux S is incident in a nearly vertical direction to the undersurface of sample 21, while the light transmitted upward is inflected with a reflecting mirror M to send to an integrating sphere 24 equipped with a detector. The control-side light flux R incident in parallel to the sample-side light flux S is inflected with reflecting mirrors M2 to M4 so as to bypass the sample 21 to be introduced to the integrating sphere 24. The measuring position is, therefore, freely changeable by shifting the sample position, without necessity to prepare holders fitted with magnitude and geometry of the sample 21. Moreover, when the conventional standard sample room 11 is utilized, by inserting adjustable reflecting mirrors 22 and 23 into a light path, the light flux may be obtained to propagate parallelly over horizontal plane by the use of the reflecting mirrors M5 to M7.
