Abstract: PROBLEM TO BE SOLVED: To provide a high quality flat face color cathode ray tube with a tint panel combined with a press mask. SOLUTION: The outer face of a panel of the color cathode ray tube is formed approximately flat and the inner face is curved into recessed face. The longitudinal pitch of slots formed in a perforated region 2 of the press mask 1 arranged in proximity to the inner face and the connection width of bridges connecting the slots are differentiated at a central portion (A) of the perforated region 2 of the press mask 1 from those at a peripheral portion (B). The percentage of the bridges occupied per unit area is larger at the central portion (A) than at the peripheral portion (B), or the percentage of the slots opened per unit area is larger at the peripheral portion (B) than at the central portion (A).  Thus, the mechanical strength of the press mask is greater at the central portion (A), inhibiting the undersired deformation of the press mask 1 due to a so-called doming phenomenon resulting from the application of external impulse or temperature rise with the increase of the radius of curvature of the central portion (A) and permitting the uniform brightness all over the screen.

IPC: E04G21/02
Filed: 2000-03-15
Abstract: PROBLEM TO BE SOLVED: To provide a concrete placing method which can positively prevent cracking of concrete only by using a small quantity of a contraction preventive agent. SOLUTION: This concrete placing method is carried out by placing uncured concrete over a cured concrete body at least twice to form at least two concrete layers. According to the method, at least the undermost uncured layer contains the contraction preventive agent, and at the same time at least the uppermost layer does not contain the contraction preventive agent or the content of the agent therein is smaller than that contained in the lowermost layer. For instance, when the concrete is placed five times so as to form five layers, the contraction preventive agent is mixed only in the undermost layer or in the two lowest layers, and the agent is not mixed in the layers upper than the second lowest layer. Alternatively, mixed proportion of the contraction preventive agent may be progressively reduced from the undermost layer to the uppermost layer.  In this case, the agent may not be mixed in the uppermost layer or in the layer in the vicinity thereof.
