  • Patent number: 10582773
    Abstract: Wobbling among components is reduced. The seat reclining device includes: outer rolling members (80) disposed between a ring-shaped bottom surface portion (71) of a mounting ring (70) and an outer surface of a guide bracket (20) or an outer surface of an internal gear (30), that faces the ring-shaped bottom surface portion (71); and inner rolling members (90) which are disposed between opposed surfaces of guide groove portions of the guide bracket (20) and lock plates (60A to 60D) to guide the lock plates (60A, 60C) in a radial direction. Owing to the outer rolling members (80) and the inner rolling members (90), force pressing stacked members relatively to one another functions in a stacking direction, and as its reaction force, spring force of the mounting ring (70) acts, so that wobbling is reduced.

  • Patent number: 10455122
    Abstract: Device-independent coordinate values at an adjustment point are converted into second coordinate values in accordance with a B2A table of an output profile, and the second coordinate values are converted into adjustment target PCS values, which are the device-independent coordinate values, in accordance with an A2B table of the output profile. When values obtained by adding relative values of an adjustment target using PCS coordinates as a reference, are assumed as target PCS values, in an optimization step, an optimization process is carried out to obtain an optimal solution of adjustment color values. The optimization process includes an element for bringing provisional PCS values, obtained by converting, in accordance with the A2B table, provisional color values obtained by adding adjustment color values to the adjustment target color values, closer to the target PCS values.
