  • Publication number: 20040150769
    Abstract: A color filter substrate for a display device includes pixels arranged in columns and rows. The substrate includes color filters, each being associated with one of the pixels and including at least two A-color filters in a first color and at least two B-color filters in a second color. Each row is associated with a group of color filters including at least one of the A-color filters and at least one of the B-color filters. Each of the A-color and B-color filters has first and second sides defining a width in the row direction. The area SA of each A-color filter is greater than the area SB of each B-color filter. The first side of each B-color filter has at least one recess, and the first side of each B-color filter has a shape that is defined by forming a recess on the first side of each A-color filter toward the second side thereof in the row direction.

  • Patent number: 4879886
    Abstract: A circular knitting machine comprising a knitting assembly for forming a tubular knitted fabric, fabric transport rollers for delivering the fabric from the assembly, a take-up spool for rolling up the delivered fabric thereon, and a pair of opposed frames stoppably rotatable about a vertical axis in synchronism with the knitting assembly. The rollers and the spool are supported by the frames. A constant torque is transmitted from a drive transmission for the frames to the transport rollers by a constant-torque transmission utilizing a magnetic force, while the spool is driven with power transmitted from the drive transmission through a belt transmission, so that the fabric knitted at a high speed can be rolled up properly. The spool comprises a pair of divided spool members and is therefore easily withdrawable from the rolled-up fabric.
