Publication number: 20230115132Abstract: A subject S to which 17O gas has been administered is placed within a fixed uniform static magnetic field of an NMR apparatus 1. The subject is irradiated, through proton coupling, with an excitation pulse produced using a pulse sequence having a short cycle time of 20.4 msec or less, preferably 10.4 msec or less, and more preferably 5.6 msec or less. An NMR signal generated due to 17O nuclei of 17O water produced within the subject by oxygen metabolism of the 17O gas being excited by irradiation with the excitation pulse is detected with high sensitivity and is processed in accordance with a prescribed imaging sequence in which an MRS sequence is used.Type: ApplicationFiled: March 5, 2021Publication date: April 13, 2023Inventors: Masashi TSUDA, Masayuki TSUDA, Noboru NAKAYAMA, Shigeru NAKAOKA

Patent number: 11377358Abstract: A novel method for producing a porous carbon material which makes it possible to easily produce a porous carbon material having a desired shape. The method includes immersing a carbon-containing material having a desired shape and composed of a compound, alloy or non-equilibrium alloy containing carbon in a metal bath, the metal bath having a solidification point that is lower than a melting point of the carbon-containing material, the metal bath being controlled to a lower temperature than a minimum value of a liquidus temperature within a compositional fluctuation range extending from the carbon-containing material to carbon by decreasing the other non-carbon main components, to thereby selectively elute the other non-carbon main components into the metal bath while maintaining an external shape of the carbon-containing material to give a porous carbon material having microvoids.Type: GrantFiled: February 27, 2020Date of Patent: July 5, 2022Assignees: TOHOKU TECHNO ARCH CO., LTD., TPR CO., LTD.Inventors: Hidemi Kato, Masashi Tsuda, Yugo Takano, Yosuke Suzuki, Tsutomu Chino, Koji Kamata, Shota Muronaka
