  • Patent number: 12187075
    Abstract: A tire comprises a tread portion having a tread surface and buttress surfaces. The buttress surfaces have inclinations such that the tread edges shift axially outwards as the tread portion is worn off. The tread rubber includes a radially outermost first rubber layer and a radially inner second rubber layer. The loss tangent ?2 of the second rubber layer is larger than the loss tangent ?1 of the first rubber layer. One of or each of the buttress surfaces is provided with an outer lateral groove. The outer lateral groove is located axially outside the tread edge when the tire is new, and when the tread portion is worn off and the tread edge shifts axially outward, the outer lateral groove is at least partially located axially inward of the tread edge.

  • Publication number: 20240014200
    Abstract: The present invention provides a method of relocating optical devices onto a carrier substrate in a case where a pixel pitch of a display is not an integer multiple of a pitch of the optical devices arrayed on a sapphire substrate. A moving speed ratio between a donor substrate and a receptor substrate is determined from an array pitch (3, 4) of optical devices (2) formed on the sapphire substrate and an array pitch (5, 7) of optical devices to be transferred onto a carrier substrate (6), and the optical devices are subjected to LIFT (laser transferred) in synchronization with movement of the donor substrate, whereby the optical devices on the sapphire substrate are transferred onto the carrier substrate at an array pitch that is identical to the pixel pitch of the display.
