  • Patent number: 11180405
    Abstract: 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.

  • Patent number: 5873665
    Abstract: A printer for printing characters and images on recording paper comprising: a paper cassette for storing the recording paper; a platen roller around which the recorrding paper is wound at the time of the transfer of images for printing; a clamping mechanism for clamping the recording paper between the clamping mechanism and the platen roller; a motor for driving the platen roller through a gear unit; a thermal printing head for transferring images onto the recording paper; paper feeding rollers for feeding the recording paper from the paper cassette to the clamper; paper discharging rollers for discharging the recording paper upon the completion of the transfer of images thereto; and an ink cassette storing an ink sheet inside thereof; in which the clamping mechanism comprises a clamper which is mounted on the platen roller in such a manner as to permit the free movement of the clamper, holds the recording paper by pushing the recording paper onto the platen roller in a first position and also releases the re

  • Patent number: 5796443
    Abstract: 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.

  • Patent number: 5421660
    Abstract: An output mechanism printer which prints characters and images on recording paper includes an input path along which a sheet of paper is conveyed towards the printing unit, a cylindrical platen roller having a longitudinal axis of rotation which is orthogonal to the input direction, and an output device which moves the sheet in the same direction as the input direction, and then automatically moves the paper directly parallel to the longitudinal axis of the platen until it is outside the printer.
