An area S (m) of a facing surface of each of injectors which faces a glass ribbon is set so as to satisfy: S&#x2266;(0.0116&#xd7;P&#xd7;Cg&#xd7;T)/{&#x3b5;&#xd7;F&#xd7;&#x3c3;(T&#x2212;T)}, wherein P is an output (ton/day) of the glass ribbon; Cg is a specific heat (J/(kg&#xb7;&#xb0; C.)) of the glass; T is an acceptable temperature drop (&#xb0; C.); &#x3b5; is radiation factor; F is a surface-to-surface view factor; &#x3c3; is Boltzmann's constant; Tis a temperature (K) of the glass ribbon represented by K=(T+T)/2 where Tand Tare measured values of the glass ribbon at the inlet and outlet of the injector, respectively; and Tis a temperature (K) of the facing surface of the injector.

Method for manufacturing glass substrate with layered film

A method for producing active glass nanoparticles that exhibit upconversion is described. The method employs pulsed-laser ablation of an active glass substrate using, for example, a high repetition rate ultra-short pulse duration laser under normal atmospheric conditions or in a liquid environment.

Method for producing active glass nanoparticles by laser ablation

It is to provide a method for removing a tin defect present on the surface of a glass substrate produced by a float process in a short time without the glass substrate surface being damaged regardless of the glass temperature. A method for removing a tin-containing foreign matter from the surface of glass, which comprises applying to the surface of a glass substrate produced by a float process a pulse laser beam having a transmittance of at least 70% through the glass substrate and having a pulse width, a wavelength and an energy density per unit area on the glass substrate surface which satisfy specific relations, to remove a tin-containing foreign matter present on the rear face opposite to the face irradiated with the pulse laser beam.
