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.

Abstract: In order to avoid undesirable loss of color disparity in the performance of a cathode ray tube of the multi-beam, multi-color, shadow mask type, it is preferable to limit the diameter of each color dot on the phosphor screen. In the process of fixing phosphor dots on a phosphor screen inside a face plate of the cathode ray tube during the fabrication thereof, a specially shaped light-emitting source is employed, in order to limit the diameter of each phosphor dot to no larger than that of each aperture in the shadow mask through which ultraviolet rays strike the screen to fix said dot. The light-emitting source has a small light-emitting point on the top of the transparent light conduit, which conduit is provided eccentrically on a shaft so that it rotates around in a small circle in a plane parallel with the face plate.

Abstract: A multivibrator circuit comprising a base bias-supplying circuit for a transistor which is connected with at least one diode in parallel with a resistor for obtaining stable temperature and voltage characteristics. This resistor serves to overcome the problem of the cessation of variations in bias voltage directly proportional to the supply voltage which is caused by the insertion of the diode. Thus it is possible to start and stop oscillation of the multivibrator circuit even when the supply voltage is reduced to a considerably lower voltage.
