  • Patent number: 12126137
    Abstract: A light-emitting element includes: a laminated structure body 20 which is formed from a GaN-based compound semiconductor and in which a first compound semiconductor layer 21 including a first surface 21a and a second surface 21b that is opposed to the first surface 21a, an active layer 23 that faces the second surface 21b of the first compound semiconductor layer 21, and a second compound semiconductor layer 22 including a first surface 22a that faces the active layer 23 and a second surface 22b that is opposed to the first surface 22a are laminated; a first light reflection layer 41 that is provided on the first surface 21a side of the first compound semiconductor layer 21; and a second light reflection layer 42 that is provided on the second surface 22b side of the second compound semiconductor layer 22. The first light reflection layer 41 includes a concave mirror portion 43, and the second light reflection layer 42 has a flat shape.

  • Patent number: 6557155
    Abstract: A method for designing routes for multilevel interconnections in a semiconductor device having at least a field effect transistor having a gate electrode, where the route extends between a diffusion region and the gate electrode. Each interconnection connected to the gate electrode is given an area which does not exceed a predetermined antenna effect reference value by inserting a buffer, such as a logic gate, into the interconnection on the same level as the interconnection.

  • Publication number: 20020078109
    Abstract: In a shift and shift-out detecting circuit, a plurality of partial shift circuits respectively have bit shift quantities which are different from each other, and are connected in series. Each of the plurality of partial shift circuits receives a shift result as a previous shift result from the partial shift circuit of a previous stage and a corresponding shift instruction, shifts the previous shift result by the corresponding bit shift quantity in response to the shift instruction to produce a current shift result, and outputs the current shift result to the partial shift circuit of a subsequent stage. A plurality of shift-out detecting circuits are respectively provided for the plurality of partial shift circuits. Each of the plurality of shift-out detecting circuits detects a shift-out of “1” bit from the current shift result and the corresponding shift instruction and generates a partial sticky signal when the shift-out is detected.

  • Patent number: 6282787
    Abstract: A nozzle rod is formed by fixing a thick diamond chip to a tip of a nozzle pipe made of a super hard metal, the other end of the nozzle pipe is thinned and the nozzle rod is joined with a shank by way of this end, a tip of the nozzle rod and vicinities thereof are so shaped as to have a predetermined sectional shape, a center hole is formed in the diamond chip by wire electro spark machining and expanded for forming a nozzle slot having a nozzle opening consisting of a center slit and “U-shaped” slits which are disposed symmetrically on both sides of a longitudinal direction of the center slit, thereby composing an electronic part adsorbing nozzle. This construction enables it to provide an electronic part adsorbing nozzle which is economical and excellent in durability.
