Abstract: The invention relates to a process for depositing under vacuum a multilayers coating stack on a flat glass substrate and to a modular coater for the deposit of thin layers on a flat glass substrate. A gas separation zone disposed between two depositing zones of the modular coater comprises at least one gas injector in the vicinity of the convoying path for the glass substrate which passes through apertures from a depositing zone towards the other depositing zone via the separation zone. The invention allows improvement of the separation factor between the two depositing zones.

Abstract: An area S (m2) of a facing surface of each of injectors which faces a glass ribbon is set so as to satisfy: S?(0.0116×P×Cg×T)/{?×F×?(Tgla4?Tinj4)}, wherein P is an output (ton/day) of the glass ribbon; Cg is a specific heat (J/(kg·° C.)) of the glass; T is an acceptable temperature drop (° C.); ? is radiation factor; F is a surface-to-surface view factor; ? is Boltzmann's constant; Tgla is a temperature (K) of the glass ribbon represented by K=(Tin+Tout)/2 where Tin and Tout are measured values of the glass ribbon at the inlet and outlet of the injector, respectively; and Tinj is a temperature (K) of the facing surface of the injector.

Abstract: A method for manufacturing a laminated film-coated glass substrate in which a laminated film is formed on a glass ribbon by a CVD method by means of a plurality of injectors disposed in an annealing furnace and the glass ribbon is cut, wherein the laminated film is formed at Tg+50° C. or lower and at least two layers of the laminated film are formed in a temperature range of Tg+50° C. to Tg. In addition, a temperature drop K1 per unit length of the glass ribbon in a temperature range where all layers of the laminated film are formed is 0° C./m<K1<10° C./m.

Abstract: The present invention provides an air-cooling/tempering device and an air-cooling/tempering method for a glass sheet, which are capable of uniformly air-cooling and tempering a glass sheet as a whole without being affected by the pitch between adjacent rollers and a roller diameter. The roller body of each roller forming the air-cooling/tempering device includes a rotary shaft formed of a guide shaft permitting a bendable action; and a plurality of ring rollers carried on the guide shaft and engaged and coupled with adjacent ring rollers; and disc rollers fixedly carried at intervals on ring rollers so as not to overlap the disc rollers on an adjacent roller with respect to a conveying direction of the glass sheet. Further, outlet modules are disposed on ring rollers between adjacent disc rollers through bearings so as to be rotatable with respect to the rotary shaft.
