Publication number: 20100289047Abstract: 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.Type: ApplicationFiled: November 28, 2008Publication date: November 18, 2010Applicant: KYOCERA CORPORATIONInventors: Yoshiyuki Kawaguchi, Kazuhiro Nishizono

Patent number: 6159349Abstract: 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.Type: GrantFiled: November 3, 1998Date of Patent: December 12, 2000Assignee: Permelec Electrode Ltd.Inventors: Shuhei Wakita, Yoshinori Nishiki, Takayuki Shimamune, Yasuo Nakajima, Masaaki Katoh, Yoshiyuki Kawaguchi, Takahiro Ashida, Masaharu Uno
