    摘要: An improvement is proposed relating to an optical isolator for bonding of the polarizer and analyzer of polarizing glass to the respective holder rings for position adjustment. The improvement comprises: (a) forming a metallized layer of a specific composition over at least two of the side surfaces of each of the polarizer and analyzer on the area of the surface excepting for the linear areas of 50 to 150 .mu.m width from the top and bottom surfaces of the polarizer or analyzer; and (b) bonding the polarizer and analyzer to the respective holder rings by soldering using a solder alloy with intervention of the metallized layer between the polarizer or analyzer and the holder ring. The invention further provides an optical part having, on at least one of the surfaces, a heat-resistant anti-reflection coating film which is a double-layered film consisting of a thin film of the titanium oxide TiO.sub.x (x=1.9 to 2.2) as the underlayer of high refractive index and a thin film of silicon dioxide as the overlayer of low refractive index.

    摘要: A fluoroscopy apparatus is adopted which includes a fluorescence-image generating section that generates a fluorescence image of a subject, a white-light-image generating section that generates a white-light image of the subject, a fluorescence-image correcting section that generates a corrected fluorescence image in which luminance values of pixels are normalized by dividing the luminance values of the pixels of the fluorescence image by the luminance values of the pixels of the white-light image, an error-image identifying section that standardizes white-light-image acquisition conditions and identifies an error region, which is a region in which the luminance values of the corrected fluorescence image exceed a preset allowable error range, on the basis of a gray level of the normalized white-light image, and a monitor that displays the error region.

A management board receiving case includes a case main body and a lid connected to the case main body and receives a management board on which a memory storing data including fiscal information and a management board-side connector are mounted. A control board receiving case includes a case main body and a lid connected to the case main body and receives a control board on which a controller and a control board-side connector connected to the management board-side connector are mounted. The management board receiving case and the control board receiving case are configured such that one box-like body that receives at least the management board is formed while the management board-side connector and the control board-side connector are connected to each other by engaging the management board receiving case with the control board receiving case through engagement members provided in the cases. The management board receiving case and the control board receiving case are configured such that engagement between the cases and engagement between the case main body and the lid in each of the cases are irreversibly maintained after the cases are engaged with each other.
