摘要： PROBLEM TO BE SOLVED: To provide a method and device for regenerating a color cathode-ray tube glass panel without forming irregularity of a panel inner surface which causes unevenness of interference generated at reuse time. SOLUTION: A panel 5 is fixed with its inner surface facing upward to a base seat 6 movable in the longitudinal direction on the same plane. While a stainless steel felt buff 8 mounted in a tip end of a sander 9 of double action rotating system to have 5 to 20 μm element wire diameter, adjusting a degree of adhesion to the inner surface of the panel 5 by an air cylinder 10, is moved in the right/left directions by a profiling arm 11 formed by copying curvature of the inner surface of the panel 5. Further, a mixed abrasive fluid of prescribed amount containing cerium oxide abrasive powder and a surfactant is supplied by a nozzle to the moving direction side in the vicinity of the felt buff 8, and the inner surface of the panel 5 is polished by this mixed abrasive fluid and the felt buff 8, to completely remove a graphite film and fluorescent film.

摘要： PURPOSE:To process all the inputted data by prohibiting the input of the data from a second host device when receiving the data form a first host device by terminal equipment, and releasing prohibition at a time when the processing is completed. CONSTITUTION:When the data AD1 from a host device A is received by an emulator 3, an affirmative response signal AR1 is transmitted to the device A, and simultaneously, interruption prohibition is applied for the processing period TA of the data AD1. The data BD1 transmitted from the host device B is stopped in a state where it is fetched in a buffer 5. When the processing of a terminal application 1 is completed, the interruption prohibition is released, and the data BD1 is fetched in a buffer 2b. Simultaneously with the transmission of an affirmative response signal BR1 to the device B, the interruption prohibition for the processing period TB of the data BD1 is applied. The data BD2 from the device B remains being kept with the buffer 5. When the processing of the data BD1 is completed, the interruption prohibition is released, and the data BD2 is fetched in the buffer 2b.

摘要： PURPOSE:To obtain a small conversion loss and a wide band frequency characteristic by providing two short-circuits, two RF signal interruption circuits and output terminals connecting to the two RF signal interruption circuits to a conventional mixer. CONSTITUTION:An RF signal inputted from a terminal 1 is fed to a diode 6 through a strip/slot converter 1, a local oscillation signal interruption circuit 2, a strip/slot converter 3, a slot/strip converter 4 and short-circuited completely by a short-circuit 9 connecting to the rear side of the board. Moreover, the local oscillation signal inputted from a terminal 2 is fed to the diode 6 through the converters 3, 4 and short-circuited by the short-circuit 9. In this case, the RF signal and the local oscillation signal are not led to a terminal 3 because of the presence of an RF signal interruption circuit 8. Furthermore, an intermediate frequency signal generated from the two diodes 6 passes through the RF signal interruption circuit 8 and is outputted from the terminal 3 after being synthesized. Thus, the conversion loss is small and wide band frequency characteristic is obtained.

摘要： PROBLEM TO BE SOLVED: To provide the manufacturing method of a color cathode ray tube with uneven color of an image eliminated by undoing the intertwining of grille lines through air blowing, prior to sealing the electron gun of a color cathode- ray tube having a shadow grille. SOLUTION: In this color cathode-ray tube, 1 represents a panel, 2 represents the grille lines of a shadow grille for controlling three colors of RGB, 3 represents IMS for shutting off external magnet, 4 represents an air chip for forming air flow for eliminating intertwining and removing impurities within a tube. Air(gas) within the tube whose flow is represented by an arrow E2 is jetted directly to a frame 7 of the shadow mask grille, then formed as a constant flow with respect to the fluorescent screen of the panel 1 and the IMS 3.

摘要： PURPOSE:To provide a color select electrode with a uniform tension using a simple and lightweight structure without sacrificing the frame rigidity by installing the electrode as set over between frames, and giving a tension to this electrode with the restoring force of support pieces consisting of a spring material. CONSTITUTION:A load is applied between frames 21a, 21b facing each other, and support pieces 22 consisting of a spring material are deflected a certain amount within the electric range, and the span between the frames 21a, 21b is compressed, where a number of thin element wires 11 are set over and welded fast. If the load is removed, the restoring force of the support pieces 22 gives required unifor tension to the element wires 11, and even though a thermal expansion is generated in the element wires 11 by irradiating with electron beam, the resultant elongation of the wires is set off with the displacement of the support pieces 22, and the element wires 11 will have approx. the same tension as the initial value. Thus a tension distribution having required uniform tention can be obtained using a simple constitution.

摘要： PURPOSE:To assuredly prevent a trespass of a metal foil in the tube inside with the metal foil adhered to an air exchange nozzle of the tube inside by detecting a presence of a remains of the metal foil coated to a neck opening part of a funnel before the air exchange nozzle is inserted into the tube inside by a through type metal sensor. CONSTITUTION:A color cathode-ray tube 4 is made to stop at the place where a through type metal sensor 7 of a ring or rectangular state is mounted with a conveyer frame 5 moved. A presence of a remains of a metal foil 2 in a neck part 1A is made to be detected with the through type metal sensor 7 penetrated into a neck part 1A of a funnel 1 and moved in the x-y direction in the stopped position. And the metal foil 2 is completely eliminated by an air-blow means etc. When the remains of the metal foil 2 exist, and only a color cathoderay tube 4 in which the metal toil 2 is completely eliminated is shifted to next pipe inside air exchange place via a movement of the frame 5. This enables carrying of a part of the metal foil 2 adhered to a nozzle inserted to the tube inside for the tube inside air exchange is assuredly to be prevented.
