Patent number: 9617298Abstract: Disclosed is a collagen powder and/or a collagen derivative powder, which are obtained by dispersing in a hydrophilic organic solvent a crude collagen precipitate which comprises 12 to 50% by mass of a collagen precipitate and/or a collagen derivative precipitate having an average particle size of 1 to 1,000 ?m, recovering solids and then drying the solids. By dispersing the crude collagen precipitate in the hydrophilic organic solvent, the resulting precipitates can be dehydrated, so that drying of the thus obtained solids can be done by air-drying. In addition, the resulting collagen powder and/or collagen derivative powder exhibit excellent solubility due to an increased specific surface area and also have excellent ease of handling with the average particle size being 8 to 1,000 ?m.Type: GrantFiled: July 29, 2011Date of Patent: April 11, 2017Assignee: NIPPI, INCORPORATEDInventors: Keisuke Tanaka, Takayuki Ogura, Shunji Hattori, Koichi Matsuda, Yoshikatsu Kobayashi, Shoji Oi

Publication number: 20150004414Abstract: Provided is a collagen structure characterized by: comprising collagen fibers of 1 to 5 ?m in average diameter; and has a water content of 0 to 15 (w/w)% and a collagen density of 50 to 800 mg/cm3. After generating collagen fibers by neutralizing an acidic collagen solution, the resulting solution is subjected to filtration or the like to form crude collagen fibers having a collagen concentration of 12 to 50 (w/v)%. The thus obtained crude collagen fibers are molded into a prescribed shape and then dried, thereby the collagen structure can be produced. Since the collagen structure is produced using, as raw material, collagen fibers that are formed by association of collagen molecules, the collagen structure has excellent cell infiltration property. Further, since the collagen density of the collagen structure is equivalent to that of in vivo collagen tissue, the collagen structure exhibits excellent tissue regeneration capacity when filled into a defective part in vivo.Type: ApplicationFiled: January 11, 2013Publication date: January 1, 2015Inventors: Takayuki Ogura, Keisuke Tanaka, Yasuhiro Ohba, Shunji Hattori

Patent number: 7248633Abstract: This invention is an MPEG decoding apparatus (10) for decoding a compression-coded image data stream, the apparatus including a motion compensation circuit (15) and error map table holding means (19) for holding an error map table with respect to a decoded frame to be referred to in performing motion compensation. When the error map table is referred to and an error block is found to be included in a reference area, or when dynamic image data of a decoding target block is broken, the motion compensation circuit (15) performs error conceal processing to interpolate a pixel in the decoding target block with a pixel in the decoded frame and output the resulting data. The motion compensation circuit (15) generates an error map table showing the error-concealed block as an error block and stores this error map table. This MPEG decoding apparatus (10) restrains propagation of an error due to the error conceal processing and reduces deterioration in image quality.Type: GrantFiled: May 27, 2003Date of Patent: July 24, 2007Assignee: Sony CorporationInventors: Takayuki Ogura, Masatoshi Takashima
