Patent number: 9764119Abstract: A urethral stricture treatment apparatus and treatment method are disclosed, which can easily inhibit the position of a medical material from deviating from a treatment site and can make the medical material selectively indwell different treatment sites. The urethral stricture treatment apparatus can have a dilation portion, which dilates in a state of holding a medical material providing an epithelial function so as to bring the medical material into contact with an inner wall of urethra, and a restriction portion which is provided in a position closer to a distal side than the dilation portion in an insertion direction such that a distance between the restriction portion and the dilation portion can be relative changed, and comes into contact with external urethral sphincter in a living body so as to restrict the movement of the medical material toward the distal side.Type: GrantFiled: September 18, 2015Date of Patent: September 19, 2017Assignee: TERUMO KABUSHIKI KAISHAInventors: Kosuke Nishio, Riyaheh S.

Patent number: 8852555Abstract: Nano-sized inorganic particles having uniform particle sizes and precisely controlled particle diameters have already been produced by synthesis in an organic solvent, but these nano-sized inorganic particles are hindered from dispersing in a polar solvent because of the adsorption of a long-chain fatty acid on the surfaces of the particles. Further, it was difficult to form nano-sized inorganic particles dispersible in a polar solvent by replacing the long-chain fatty acid coats.Type: GrantFiled: July 25, 2008Date of Patent: October 7, 2014Assignee: Tokyo Institute of TechnologyInventors: Hiroshi Handa, Mamoru Hatakeyama, Masanori Abe, Satoshi Sakamoto, Yuka Masaike, Kosuke Nishio, Yoshinori Kita, Hiroshi Kishi

Patent number: 8694326Abstract: A communication terminal includes a decoder which decodes an input bitstream received from another communication terminal, to generate an output audio signal and outputs the generated output audio signal to a speaker; and an echo canceller which obtains an input audio signal representing sound captured by a microphone placed in a space to which the speaker outputs the sound, and removes, for respective subbands, an echo component included in the obtained input audio signal and corresponding to the output audio signal, to generate an audio signal for transmission. An encoder codes the audio signal for transmission to generate an output bitstream and transmits the generated output bitstream to another communication terminal; and a control unit controls, for the respective subbands, echo cancellation processing according to a reproduction band of at least one of the output audio signal and the audio signal for transmission.Type: GrantFiled: August 21, 2012Date of Patent: April 8, 2014Assignee: Panasonic CorporationInventors: Shuji Miyasaka, Kosuke Nishio, Ichiro Kawashima
