  • Patent number: 11672051
    Abstract: An electrically heated support according to the present invention includes: a pillar shaped honeycomb structure, the honeycomb structure including an outer peripheral wall and a partition wall, the partition wall defining a plurality of cells, each of the cells penetrating from one end face to other end face to form a flow path; and a pair of electrode terminals provided on a surface of the outer peripheral wall. In a cross section of the honeycomb structure, the honeycomb structure includes: a plurality of first slits arranged, the first slits being configured to define an energizing path; and a least one second slit located in the energizing path, the second slit extending in a different direction from that of the first slits. A length of the energizing path from one electrode terminal to the other electrode terminal is longer than a diameter of the honeycomb structure.

  • Patent number: 7741649
    Abstract: In a semiconductor light emitting device, a semiconductor light emitting element has a light extracted surface on which a plurality of convex structures is formed. The convex structures each have a conical mesa portion constituting a refractive index gradient structure, a cylindrical portion constituting a diffraction grating structure, and a conical portion constituting a refractive index gradient structure. The mesa portion, cylindrical portion, and conical portion are arranged in this order from the light extracted surface. The period between the convex structures is longer than 1/(the refractive index of an external medium+the refractive index of the convex structures) of an emission wavelength and equal to or shorter than the emission wavelength. The circle-equivalent average diameter of the cylindrical portion is ? to 9/10 of that of the bottom of the mesa portion.

  • Patent number: 7179672
    Abstract: A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved. The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index.
