  • Patent number: 11309688
    Abstract: In a method for manufacturing a nitride semiconductor light-emitting element by splitting a semiconductor layer stacked substrate including a semiconductor layer stacked body with a plurality of waveguides extending along the Y-axis to fabricate a bar-shaped substrate, and splitting the bar-shaped substrate along a lengthwise split line to fabricate an individual element, the waveguide in the individual element has different widths at one end portion and the other end portion and the center line of the waveguide is located off the center of the individual element along the X-axis, and in the semiconductor layer stacked substrate including a first element forming region and a second element forming region which are adjacent to each other along the X-axis, two lengthwise split lines sandwiching the first element forming region and two lengthwise split lines sandwiching the second element forming region are misaligned along the X-axis.

  • Patent number: 6255081
    Abstract: The present invention relates to a thermostable Flap endonuclease whose optimum temperature is 75° C. or more and DNA coding for (a) a protein consisting of the amino acid sequence shown in SEQ ID NO:2 or (b) a protein with Flap endonuclease activity, consisting of an amino acid sequence where in the amino acid sequence (a), one or more amino acids are deleted, substituted or added. According to the present invention, there is provided a thermostable Flap endonuclease whose optimum temperature for reaction is 75° C. or more. Further, this enzyme is thermally stable, so it becomes possible to develop new techniques of conducting artificial homologous recombination or genetic shuffling highly efficiently by coupling the enzyme reaction with PCR.
