Abstract: A method and device for manufacturing a CRT enables four springs to be accurately welded to the apertured grill without disordering the relative position of the pin holes in each of the springs even if simultaneous welding is not carried out. The location of the pin hole is indexed in such a way that a space between the surface of the grill and the inner surface of the panel may always be kept constant at any location under a state in which the apertured grill is fixed to the panel. The spring is welded in advance to the spring holders of the lower lateral member and the right and left vertical members in such a way that the pin hole is positioned at the indexed location. The remaining one spring is positioned in such a way that the pin hole is positioned at the indexed location when the apertured grill is positioned to cause the relative positions of the pin holes of the welded three springs to coincide with the relative arrangement of the pins of the lower, right and left skirts of the panel.

Abstract: The present invention provides a pressure device to press a pair of members facing each other of a frame under the same pressure condition. A pressure device 5 for pressing top and bottom members 103 of a frame 101 for apertured grills, provided with a pair of pressure blocks 31 provided movably in the direction to bring the pressure blocks closer to and farther from each horizontal member 103 at the position facing to the top and bottom horizontal members respectively outside the frame 101, driving means 15 for moving synchronously each pressure block 31 in the direction to bring each pressure block 31 closer to and farther from each horizontal member 103, and pressure rolls 33 for contacting with each horizontal member 103 and supported on each pressure block 31, respectively.

Abstract: A method of for developing a panel in manufacture of a cathode ray tube which prevents possible dispersion of developing liquid to achieve a good developing operation free from irregular development. The method comprises fixing a panel, jetting developing liquid by way of a nozzle toward an inner face of the panel while moving the nozzle in a direction along stripes of a fluorescent face to be formed on the inner face of the panel to perform development of the panel.

Abstract: The present invention is directed to a method of and apparatus for forming a coating film on an inner surface of a panel of a cathode ray tube. In this case, slurries are injected into the panel, the panel is rotated on its own axis so as to uniformly coat the slurries on the panel and a recovering hood is moved in an opposing relation to the panel in synchronism with the revolution of the panel to thereby recover the slurries. Therefore, particularly when the slurries are recovered, the slurries can be prevented from being scattered, thereby avoiding the surroundings from being splattered.
