  • Tapered roller bearing
    Patent number: 9453534
    Abstract: A cage 20 of a tapered roller bearing 1 holds tapered rollers 30 by plural pockets formed between a large-diameter side annular part 22 and a small-diameter side annular part 23 arranged in an axial direction, and plural bar parts 24 which axially join the large-diameter side annular part 22 and the small-diameter side annular part 23 and are circumferentially formed at substantially an equal distance. A value of a ratio of a cross section modulus of the small-diameter side annular part 23 of the cage 20 to a cross section modulus of the large-diameter side annular part 22 of the cage 20 is values from 0.5 to 1.5 (both inclusive).
    Type: Grant

  • Recording apparatus and liquid ejecting apparatus
    Patent number: 7547091
    Abstract: A liquid ejecting head is adapted to eject liquid toward a target medium. A guide shaft extends in a first direction. A carriage reciprocately carries the liquid ejecting head in the first direction while being guided by the guide shaft. A moment generator is disposed between the carriage and the guide shaft at a position shifted from a centrium of the carriage in the first direction. The moment generator exerts a force directed in a second direction perpendicular to the first direction, thereby generating a first rotation moment in the carriage.
