  • Patent number: 10242428
    Abstract: The present disclosure is related to a method for driving a transparent display device. The method includes extracting a corneal reflection image, generating a flat target image, generating a background image, and displaying the background image on a transparent display panel. The corneal reflection image includes a target image formed by projecting, on a cornea of a user, a display area of the transparent display panel divided into the display area which displays a display image and transmits light reflected from a background and a non-display area adjacent to the display area. The flat target image is generated by correcting the target image distorted by a curved shape of the cornea. The background image is formed by removing the display image from the flat target image.

  • Patent number: 9046150
    Abstract: A silent chain includes guide plates each of which has a cut-away portion on its inner side and a cut-away portion on its outer side for allowing elastic deformation of the guide plate in the longitudinal direction of the chain so that bowing of the connecting pins of the chain is reduced, and galling of the connecting pins and unbalance of the loads on the link plates of the chain are suppressed. The deepest parts of the respective cut-away portions are longitudinally offset from each other so that longitudinal elastic deformation can occur without impairing the tensile strength of the guide plate.

  • Patent number: 8602932
    Abstract: There is provided a chain comprising guide link rows and non-guide link rows disposed alternately along the length of the chain with each plate of each row overlapping each plate of each of two adjacent rows. For each guide link row, a pair of pins is provided for connecting the guide link rows and non-guide link rows in articulating relationship. The first connecting pin extends into a first hole of each of the guide plates of its guide link row and into and through the second hole of each link plate of an adjacent non-guide link row. The second connecting pin extends into a second hole of each of the guide plates extends into and through a first hole of each link plate of an adjacent non-guide link row. The connecting pins fit tightly into each first hole into which it extends and fits loosely in each second hole into which it extends.
