The present invention relates to a method for producing a float glass sheet, containing a step of melting a glass source material, a step of forming the glass melted in the previous step into a glass ribbon while allowing it to float on a molten metal, and a step of annealing the glass ribbon, in which the float glass sheet is a soda lime silicate glass, and in the forming step, a top surface of the glass ribbon that is opposite to a bottom surface thereof to be in contact with the molten metal is subjected to a dealkalization treatment in the float bath for 1 to 30 seconds and a surface temperature of the glass ribbon during the dealkalization treatment is 600 C. or higher.


The present invention relates to a method for producing phase-separated glass, sequentially including a melting step of melting a glass, a phase separation step of separating phases in the glass, and a shaping step of shaping the glass, and to the phase-separated glass obtained by the production method.

To provide a method for efficiently separating 2,3,3,3-tetrafluoropropene (HFO-1234yf) and chloromethane (R40) from a composition containing HFO-1234yf and R40. A method for separating HFO-1234yf containing substantially no R40, which comprises bringing an azeotropic composition or azeotrope-like composition of HFO-1234yf and R40 into contact with a specific extraction solvent.


To provide a coating solution for forming an ultraviolet-absorbing film which has mechanical durability such as abrasion resistance and which is little susceptible to deterioration of the ultraviolet-absorbing ability by use for a long period of time, and an ultraviolet-absorbing glass article having an ultraviolet-absorbing film formed by using such a coating solution, which has mechanical durability such as abrasion resistance and which is little susceptible to deterioration of the ultraviolet-absorbing ability by use for a long period of time. A coating solution which comprises a component derived from an epoxidized organooxysilane compound, a component derived from an organooxysilane compound which is a reaction product of a hydroxylated benzophenone compound and an epoxidized organooxysilane compound, and a component derived from an organooxysilane compound other than the above both organooxysilane compounds, and an ultraviolet-absorbing glass article obtained by using the coating solution.

An antenna device includes an antenna conductor on windshield glass, a feeding point having adjacent first and second feeding parts on the antenna conductor, and an auxiliary conductor including electrically connected horizontal and vertical conductors. The antenna conductor is adjacent to a connecting part between the horizontal and vertical conductors, and has a semi-loop shape with a cutout part in a loop-shape. The feeding point is located along the horizontal conductor, and the cutout part is located opposite from the horizontal conductor with respect to a horizontal line passing through a center point of a region surrounded by a semi-loop element, and opposite from the vertical conductor with respect to a vertical line passing through the center point. A length of a first element forming a part of the antenna conductor is 0.2
