Publication number: 20070259036Abstract: A process for producing a lactic acid polymer of 15,000 to 50,000 in weight-average molecular weight, the content of polymeric materials having not more than about 5,000 in weight-average molecular weight therein being not more than about 5% by weight, characterized by hydrolyzing a high molecular weight lactic acid polymer, placing the resultant solution comprising the hydrolyzed product under a condition capable of precipitating the objective lactic acid polymer, separating the precipitated lactic acid polymer and collecting them. The lactic acid polymer is useful as a matrix for sustained-release preparations. The sustained-release microcapsule preparation encapsulating a physiologically active substance can fully prevent the initial excessive release of the physiologically active substance from the microcapsules and keep a stable release rate over a long period of time.Type: ApplicationFiled: July 2, 2007Publication date: November 8, 2007Inventors: Kohei Yamamoto, Tsutomu Tani, Takashi Aoki, Yoshio Hata

Patent number: 6453439Abstract: A pseudo product code decoder effects error correction by using parity symbols of a first linear-structure error correction code contained in an input symbol train that constitutes a pseudo product code and by using parity symbols of a second linear-structure error correction code. Second-series information symbols are extracted from the symbol train; and a subtraction code of a pseudo product code codeword is formed of the second-series information symbols, with the first-series information symbol portion and the second linear-structure error correction code portion being changed to zero codes. The pseudo product code codeword is transformed into a product code codeword by subtracting processing with the subtraction code. Decoding processing is performed a plurality of times on the symbol train of the product code codeword, thereby effecting error correction; and first-series information symbols are extracted from the error corrected symbol train.Type: GrantFiled: February 10, 2000Date of Patent: September 17, 2002Assignee: Sony CorporationInventors: Masayuki Hattori, Kohei Yamamoto

Patent number: 5523122Abstract: The distance between a D-roll and a C-roll is switched at proper time intervals between two stages in which the distance is larger or smaller. A thicker coating layer on the C-roll with the thickness controlled by the larger distance between the D-roll and the C-roll is transferred onto a base sheet in a condition in which the C-roll and a B-roll are in contact with each other with the base sheet interposed therebetween. The distance between the C-roll and the B-roll is increased when a thinner coating layer on the C-roll with the thickness controlled by the smaller distance between the D-roll and the C-roll reaches a transfer position, so that the coating layer is not transferred onto the base sheet. A local increase of the amount of the coating material applied at the end of a coating area can be prevented, and the thickness of the coating material applied can be controlled to be constant with high accuracy over the entire coated area.Type: GrantFiled: September 9, 1994Date of Patent: June 4, 1996Assignees: Fuji Electrochemical Co., Ltd., Hirano Tecseed Co., Ltd.Inventors: Yoshiro Harada, Kohei Yamamoto, Kazuhiko Hironaka, Hiroshi Kobara
