Patent number: 9539366Abstract: It is intended to provide a medical material which enables a new method for cartilage tissue regeneration treatment based on an entirely new concept unlike a treatment method by transplantation of autologous cartilage tissue, a cartilage alternative or undifferentiated cells. The invention provides a bone filler for cartilage tissue regeneration comprising hydrogel having an interpenetrating network structure formed by two or more crosslinked network polymers or a semi-interpenetrating network structure formed by a crosslinked network polymer and a linear polymer. By filling the bone filler of the invention in a hole or a groove provided in subchondral bone just under damaged cartilage tissue, regeneration of the cartilage tissue or both the cartilage tissue and the subchondral bone can be promoted.Type: GrantFiled: June 30, 2011Date of Patent: January 10, 2017Assignee: National University Corporation Hokkaido UniversityInventors: Kazunori Yasuda, Yoshihito Osada, Jian Ping Gong, Nobuto Kitamura

Patent number: 8369456Abstract: A data processing apparatus able to start decoding at a timing earlier than the conventional timing and able to reduce the storage capacity required for a storing means for storing the encoded data until a decoding side decodes the input encoded data in comparison with the conventional storage capacity, which apparatus selects frame data from frame data f(5) having the last decoding order to frame data f(0) having the first decoding order for processing for calculating a delay time min_delay and calculates the delay time min_delay. It calculates the delay time min_delay indicating the delay time from when the decoding side starts to receive input of the frame data to when the data is decoded based on the specified size and the bit rate of the input of the frame data to the decoding side for each of the frame data for processing.Type: GrantFiled: January 15, 2010Date of Patent: February 5, 2013Assignee: Sony CorporationInventors: Markus Hendriks Veltman, Kazunori Yasuda
