摘要： A tempered glass includes a glass sheet having a thickness of 2.3-3.5 mm, an average surface compressive stress of 1000-1300 kg/cm2, and a plurality of first and second belt-like regions. Each of the second belt-like regions is interposed between adjacent ones of the first belt-like regions. Each of the first belt-like regions has a width of 10-30 mm and a plurality of first reference points, each having a principal stress difference of 120 kg/cm2 or less, which is larger than principal stress differences at areas of each of the first belt-like regions which are peripheral to each of the first reference points. The first principal stress difference at each of the first reference points is located in a direction perpendicular to the length of the first belt-like regions. Lines connecting adjacent ones of the first reference points form a center line, as a reference line, of each of the first belt-like regions. Each of the second belt-like regions contain a plurality of second reference points, each having a second principal stress difference which is larger than principal stress differences at areas of each of the second belt-like regions which are peripheral to each of the second reference points. The second principal stress difference extends in at least two different directions, one direction being substantially perpendicular to the first direction of the first principal stress difference and being located at peripheral edges of each of the second belt-like regions, and another direction being oblique to the first direction of the first principal stress difference. The two different directions of the second reference points forms a pattern. The pattern is a snaking line having undulations which are approximately trapezoidally-shaped.

摘要： A quenching method and apparatus for tempering a glass sheet. The method includes a step of transferring a heated glass sheet between quenching boxes which are provided with nozzles opposingly arranged near upper and lower surfaces of the glass sheet to blow air streams of cooling air supplied from the quenching boxes to the glass sheet. The method also includes the step of arranging the nozzles extending from the quenching boxes so as to face at least one of the upper and lower surfaces of the glass sheet so that openings on the end of the nozzles blow the air streams of the cooling air in different directions simultaneously so as to intersect and thus be substantially uniformly arranged with respect to the glass sheet. The number of intersections is approximately 30 or more in any 10 cm square area of the glass sheet. The end portions of the nozzles have a semi-spherical shape. The apparatus includes quenching boxes arranged opposing the surfaces of the glass sheet, and nozzles extend from the quenching boxes so that air streams of cooling air are blown towards the glass sheet which has been heated to a predetermined temperature. Each of the nozzles has a tubular form with a semi-spherically shaped end portion opposing the surfaces of the glass sheet. The end portions of the nozzles each have a plurality of openings so that air streams of cooling air supplied from the quenching boxes are blown towards the surfaces of the glass sheet. The openings formed are uniformly arranged in the end portion of the nozzles.
