  • Publication number: 20100289047
    Abstract: Provided is a light emitting element capable of improving light extraction efficiency and suppressing the nonuniformity of emission intensity distribution over the entire surface of a light extraction surface. The light emitting element is provided with a semiconductor multilayer body having an n-type semiconductor layer and an emission layer and a p-type semiconductor layer, and an electrode pad connected to the p-type semiconductor layer. The semiconductor multilayer body has a large number of projections on one main surface thereof through which the light from the emission layer is emitted. The main surface of the semiconductor multilayer body has a first region located in the vicinity of the electrode pad, and a second region being further separated from the electrode pad than the first region. The interval between the projections in the second region is smaller than that in the first region.

  • Publication number: 20070015306
    Abstract: A p type group III nitride semiconductor layer can be manufactured without causing its crystal deterioration, and without requiring any complicated post-treatment, by repeating a plurality of times the following steps: the step A of growing a group III nitride semiconductor layer containing p type impurities; the step B of discontinuing the growth of the group III nitride semiconductor layer by stopping supplies of the respective material gases and the carrier gas, and replacing an atmospheric gas within a film forming apparatus with an inert gas, and reducing a temperature of the substrate from a growth temperature; and the step C of resuming the growth of the group III nitride semiconductor layer by again raising the temperature of the substrate and supplying the material gases and the carrier gas into the film forming apparatus.

  • Patent number: 6159349
    Abstract: An electrolytic cell for producing a brine containing hydrogen peroxide is disclosed. Units for hydrogen peroxide production 3 and units for water electrolysis 2 are alternately arranged in the same electrolytic cell 1. Electrolysis is conducted while supplying hydrogen gas and oxygen gas generating in the respective water electrolysis units to a gas diffusion anode 11 and a gas diffusion cathode 13 of each unit for hydrogen peroxide production, to thereby obtain a brine containing hydrogen peroxide in a high concentration. Furthermore, because the anode of the hydrogen peroxide production units is a hydrogen gas diffusion anode having a reduced oxidizing ability, halogen ions contained in the seawater do not yield harmful halogenated organic substances.

  • Patent number: 4757020
    Abstract: Expression plasmids containing the full cDNA sequence of calf prochymosin and capable of expressing prochymosin gene in E. coli host cells are disclosed. A method is described for the preparation of said plasmids which comprises altering the spacing between the SD and ATG sequences within the E. coli trp promoter-operator region of the parent expression plasmid, pCR 701, which is known to express prochymosin gene in the E. coli host cells. These modified expression plasmids are designed to provide high expression levels of prochymosin.
