    Abstract: A decimal point display circuit for use in an electronic desktop calculator, etc. which displays the result of a calculation or an entry number from the higher digits when it exceeds the number of digits in the numerical display, and displays the number of digits above the decimal point but not displayed in the numerical display by a digit mark in the numerical display. Even when the number of digits of the result of a calculation or an entry number exceeds the number of digits in the numerical display, it can be displayed in such a manner that the digits in the numerical display serve as the effective digits.

    Abstract: A target assembly of an image pick-up tube is provided which includes a stepped annular support member for a target substrate secured between a face plate and a front end portion of a tubular envelope of the image pick-up tube. The target substrate is affixed within the outwardly offset portion of the support member. The support member enables a fabrication sequence to be used which obviates exposure of the target substrate to mechanical or thermal shock during manufacture, permits the affixing material to be out of the field of view in a straightsides image pick-up tube, and furnishes automatically accurate centering of the target substrate. In combination with a softmetal sealing ring having an annular width extending from the inwardly offset portion of the support member to the inner side of a signal ring capping the face plate and the envelope, the support member also insulates the target substrate from mechanical shock during use of the image pick-up tube.

    Abstract: A phosphor screen for color picture tube is usually produced by the first step which comprises suspending a blue emission phosphor in an aqueous solution of photo-setting photosensitive material comprising polyvinyl alcohol and ammonium dichromate, applying thus obtained suspension to inner surface of face panel to form a photosensitive film, exposing said film through apertures of shadow mask and developing the exposed film to form dotty phosphor film and the second and the third steps of forming the dotty phosphor films of green and red emissions in this order by substantially the same procedure as that of the first step. According to the present invention, the dotty phosphor films formed at said first and second steps are treated with chromic acid solution to harden said films, whereby color mixing, namely, so-called color fogging caused by a phosphor of other color emission used at the subsequent step is reduced and color purity of emission from phosphor screen face is improved.
