Title: Warpage correction apparatus and method for metallic foil-clad laminated plate
Inventor: IWATA TERUHIKO
IPC: B32B15/08
Filed: 1988-11-15
Abstract: PURPOSE:To obtain a metallic foil-clad laminated plate having no warpage and no change in size by arraying in a zigzag pattern three or more rollers so that the rollers are positioned in a furnace at right angles therewith in the longitudinal direction of the furnace retaining a preset temperature. CONSTITUTION:A metallic foil-clad laminated plate 4 introduced into a heating furnace 1 first passes between rollers 2 for elevating a temperature, which vertically form a pair. In this process, the metallic foil-clad laminated plate 4 receives heat from an atmosphere in the heating furnace and, at the same time, also receives heat from the rollers 2 for elevating a temperature because the plate 4 is brought into contact with the rollers 2 for elevating a temperature. Further, an electric heater is inserted into the rollers 2 for elevating a temperature to warm up the whole rollers so as to promote the temperature rise of the metallic foil-clad laminated plate 4. Then, the metallic foil-clad laminated plate 4 whose temperature has been elevated to the level of a glass transition temperature or higher passes between rollers 3 for collecting the warpage of the plates, which are arranged in a zigzag pattern, whereby the metallic foil-clad laminated plate is repeatedly subjected to the bending processing so that residual strain is removed and the warpage is corrected. Further, after-cure is performed by heating in the heating furnace 1.

Title: Liquid crystal display device
Inventor: SHIROKURA HIDEAKI
IPC: H05K3/32
Filed: 1994-11-24
Abstract: PURPOSE: To prevent the occurrence of contact defect of TAB sheet by diagonally arranging flexible sheet so as to gradually widen the spacing between the sheets in the non-superposed parts toward a second insulatable substrate. CONSTITUTION: The flexible TAB sheet 26 is arranged diagonally on the first insulatable substrate 20 so as to expand toward the second insulatable substrate (display region) 21. There is a possibility that crack and disconnection are generated in the lower wiring of a flat conductive ball 29 on the extreme right, but the ball having a good pressurized state exits always on the left of this conductive ball and the contact is attained. Connection is made possible on the front end side of a terminal even if a burr exists on the side face of the second insulatable substrate 21 if the flexible sheet 26 is diagonally arranged and, therefore, the influence of the burr is eliminated. Since the conductive ball 28 on the terminal side is strongly pressurized, the contact is attained even if the pressurization of the conductive ball on the display side is weakened by the burr.
