Patent number: 11180405Abstract: Provided is a sheet glass production process for properly producing sheet glass having a convex shape in section in a width direction orthogonal to the advancing direction of a glass ribbon. A glass ribbon G2 advancing on molten metal 22 is heated so as to have both edge portions G2B heated more intensely than a central portion G2A in a width direction thereof in an upstream zone of the molten metal bath, and a plurality of rolls 23 are rotated in contact with both edge portions G2B of the glass ribbon G2 such that upstream rolls 23A in an advancing direction F1 have a lower peripheral speed than downstream rolls 23B in the advancing direction.Type: GrantFiled: March 10, 2020Date of Patent: November 23, 2021Assignee: AGC Inc.Inventors: Takamitsu Yamato, Kouhei Sunaga, Akira Hasegawa, Akira Sugahara

Patent number: 5796443Abstract: A projection television includes a video projector for projecting a video image, electrical circuit for supplying a video signal to the video projector, and screen on which the video image projected from the video projector is formed. At least the screen is arranged in a first housing and at least the video projector is arranged in a second housing. The projection television is adapted to be disassembled either into two separate housings or into one overall assembly where a housing of a smaller volume of the two housings is completely accommodated within a housing of a larger volume. The second housing may be pivotally coupled to the first housing so that the second housing pivots out of the first housing to a first position to project the video image onto the screen when assembled for viewing, and into the first housing to a second position to be completely accommodated in the first housing.Type: GrantFiled: October 16, 1996Date of Patent: August 18, 1998Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Shinobu Kawajiri, Shinji Koubara, Kouhei Sunaga
