    摘要： Method and apparatus for measuring a surface temperature of an object body, by calculating a temperature at each picture element of an image of the object body, on the basis of a radiant intensity ratio at each pair of corresponding picture elements of a first and a second image which are obtained with respective radiations having respective first and second wavelengths which are selected from a light emitted from the surface of the body, by a first filter which permits transmission therethrough a radiation having the first wavelength which is selected according to a radiant intensity curve corresponding to a wavelength of a black body at a lower limit of a temperature measurement range, and which is within a high radiant intensity range in which the radiant intensity is higher than a radiant intensity at a normal room temperature, and a second filter which permits transmission therethrough a radiation having the second wavelength which is selected within the high radiant intensity range, such that the second wavelength is different from the first wavelength by a predetermined difference which is not larger than null of the first wavelength and which is not smaller than a sum of half widths of the first and second wavelengths.

    摘要： A roller conveyor device including a three-line conveyor for conveying objects that form at least three lines extending in a conveying direction. The three-line conveyor includes first conveyor rollers for conveying ones of the objects that form at least one central line of the at least three lines, second conveyor rollers for conveying ones of the objects that form at least one non-central line of the at least three lines, and third conveyor rollers for conveying ones of the objects that form another at least one non-central line of the at least three lines. A rotary shaft of each of the first, second and third conveyor rollers includes a shaft end portion having a projection portion that projects out from a conveying path in a widthwise direction of the conveying path, and the projection portion is to be driven so as to convey the objects in the conveying direction.

    摘要： An inkjet ink for a glass substrate can enable formation of an aesthetic image with high concealability on the surface of the glass substrate. The inkjet ink disclosed here can include: an inorganic solid including an inorganic pigment that develops black and a glass frit; a monomer component having a photocuring property; and a photoinitiator. In the inkjet ink, a volume ratio of the inorganic solid in a case where an ink total volume is 100 volume% can be 35 volume% or less, a volume ratio of the inorganic pigment in the case where a total volume of the inorganic solid is 100 volume% can be 15 volume% or more and less than 90 volume%, and a volume ratio of the inorganic pigment to the photoinitiator can be 6 times or less.
