  • Reflective spiral phase plate, and apparatus for generating Laguerre Gaussian beam comprising same
    Patent number: 11947104
    Abstract: A spiral phase plate, according to one embodiment, for generating a Laguerre Gaussian beam by reflecting an incident beam emitted from a light source, may comprise: a first quadrant area in which the step height increase rate per unit angle decreases progressively in one direction from the point with the lowest step height to the point with the highest step height; and a second quadrant area in which the step height increase rate per unit angle increases progressively in the one direction.

  • Rack assist type electric power steering apparatus
    Patent number: 8540258
    Abstract: A rack-assist type electric power steering apparatus, in which when a ball nut slides a rack bar while rotating, a vibration and a noise in the axis direction and the radial direction, generated from the rack bar and a rack housing, are absorbed. This facilitates the operation of the ball nut and the rack bar, and reduces the vibration and the noise, thereby resulting in an effect for providing a comfortable steering feeling to a driver.
