Abstract: A glass plate having printed conductive members, comprises a functional strip (30) being a printed conductive member, a first bus bar (20a) electrically connected to an end of the functional strip and being a printed conductive member, a second bus bar (20b) electrically connected to the other end of the functional strip and being a printed conductive member and a printed dark ceramics (13) provided along the periphery of a glass plate (10), wherein the bus bars (20a, 20b) are provided on the printed dark ceramics and have cut-out portions (23a, 24a) in which the printed dark ceramics is exposed. Generation of uneven temperature distribution due to the difference of heat absorptivities between the printed dark ceramics and the bus bars is prevented, whereby a glass plate having printed conductive members is provided by more simple method and at lower cost than before.

Abstract: A method for manufacturing a curved sheet of glass which includes a heating furnace for heating a sheet of glass therein, the heating furnace having an outlet opening for discharging a curved sheet of glass, and an array of beds housed in the furnace for transferring a sheet of glass successively over the beds in the furnace in a first direction toward the outlet opening while shaping the sheet of glass complementarily to an upper surface of the beds, each of the beds having a plurality of hot air ejecting holes for ejecting hot air to keep the sheet of glass out of contact with the beds, the beds including a final bed disposed near the outlet opening and inclined upwardly toward the outlet opening, the final bed having an upper panel including at least a portion curved in the first direction near the outlet opening to curve the sheet of glass in the first direction.

Abstract: A process for bend-shaping a glass plate by heating the glass plate to a softening temperature of the glass plate, while the glass plate is transferred along a transferring surface in a shaping furnace. The glass plate is transferred along a complex bending transferring surface having a complex curved face which is upwardly projected with predetermined radius of curvatures along both the axis of the transferring direction and the axis perpendicular to the transferring direction.
