Publication number: 20240140753Abstract: A sheet storing device includes: a rotary drum; a tape that winds a sheet on the rotary drum; a guide that guides the tape and the sheet to be wound on the rotary drum; and a frame that accommodates the rotary drum and the guide. The frame includes a first frame and a second frame. The first frame and the second frame are connected movably relative to each other to change the frame between an open state and a closed state. The second frame supports the guide to cause at least a part of the guide to move relative to the second frame in a direction away from the second frame in the open state.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Applicant: Glory Ltd.Inventors: Hiroyuki YANAI, Takeshi YOKAWA

Publication number: 20240132318Abstract: A sheet storing device includes: a rotary drum; at least one tape that wraps a sheet around the rotary drum; and at least one first pressing member that is shifted from the tape along an axis of the rotary drum and presses the sheet against the outer circumferential surface of the rotary drum. The first pressing member presses the sheet against the rotary drum at or near a starting point at which the tape to be wound on the rotary drum first comes into contact with the rotary drum.Type: ApplicationFiled: January 3, 2024Publication date: April 25, 2024Applicant: Glory Ltd.Inventors: Takeshi YOKAWA, Hiroyuki YANAI

Patent number: 11250976Abstract: The present invention provides a rare earth thin film magnet having Nd, Fe, and B as essential components, wherein the rare earth thin film magnet has a texture in which an ?-Fe phase and a Nd2Fe14B phase are alternately arranged three-dimensionally, and each phase has an average crystal grain size of 10 to 30 nm. An object of this invention is to provide a rare earth thin film magnet having superior mass productivity and reproducibility and favorable magnetic properties, as well as to provide the production method thereof and a target for producing the thin film.Type: GrantFiled: March 3, 2015Date of Patent: February 15, 2022Assignee: JX Nippon Mining & Metals CorporationInventors: Masaki Nakano, Hirotoshi Fukunaga, Takeshi Yanai, Masaru Itakura, Hironobu Sawatari

Patent number: 11114225Abstract: A rare-earth thin film magnet is provided which includes Nd, Fe and B as essential components, characterized by including a Si substrate having an oxide film present on a surface thereof, a Nd base film formed as a first layer over the Si substrate, and a Nd—Fe—B film formed as a second layer on the first layer. The rare earth thin film magnet and a production process therefor provides a rare earth thin film magnet suffering neither film separation nor substrate breakage and having satisfactory magnetic properties even when the second layer has composition in the range of 0.120 ?Nd/(Nd+Fe)<0.150, which corresponds to a compositional range in the vicinity of a stoichiometric composition.Type: GrantFiled: February 28, 2017Date of Patent: September 7, 2021Assignee: JX NIPPON MINING & METALS CORPORATIONInventors: Masaki Nakano, Hirotoshi Fukunaga, Takeshi Yanai, Hironobu Sawatari

Patent number: 11072842Abstract: Provided is a rare earth thin film magnet having Nd, Fe and B as essential components, which is characterized in that a Nd—Fe—B base film is formed on a Si substrate having an oxide film formed on a surface thereof and has a composition in which the Nd content is higher than that of a stoichiometric composition and that a film (nano composite film) is formed on the base film and has a texture in which an ?-Fe phase and Nd2Fe14B are alternately arranged and three-dimensionally dispersed. The rare earth thin film magnet provided is less susceptible to the occurrence of film separation and substrate breakage and exhibits favorable magnetic properties.Type: GrantFiled: March 29, 2017Date of Patent: July 27, 2021Assignee: JX NIPPON MINING & METALS CORPORATIONInventors: Masaki Nakano, Hirotoshi Fukunaga, Takeshi Yanai, Hironobu Sawatari

Patent number: 10597771Abstract: A rare earth thin-film magnet of a Nd—Fe—B film deposited on a Si substrate, wherein, when the film thickness of the rare earth thin film is 70 ?m or less, the Nd content satisfies the conditional expression of 0.15?Nd/(Nd+Fe)?0.25 in terms of an atomic ratio; when the film thickness of the rare earth thin film is 70 ?m to 115 ?m (but excluding 70 ?m), the Nd content satisfies the conditional expression of 0.18?Nd/(Nd+Fe)?0.25 in terms of an atomic ratio; and when the film thickness of the rare earth thin film is 115 ?m to 160 ?m (but excluding 115 ?m), the Nd content satisfies the conditional expression of 0.20?Nd/(Nd+Fe)?0.25 in terms of an atomic ratio. An object of the present invention is to provide a rare earth thin-film magnet having a maximum film thickness of 160 ?m and which is free from film separation and substrate fracture, and a method of producing such a rare earth thin-film magnet by which the thin film can be stably deposited.Type: GrantFiled: October 19, 2015Date of Patent: March 24, 2020Assignee: JX NIPPON MINING & METALS CORPORATIONInventors: Masaki Nakano, Hirotoshi Fukunaga, Takeshi Yanai, Hironobu Sawatari

Patent number: 5455171Abstract: A microorganism exhibiting excellent antibiotic and sterilizing properties for the preparation of medicines and the like, obtained by fusion of cells of two different fungal species. A Ganoderma and a Grifola, each exhibiting little or no antibiotic activity, are isolated and hybridized, and milled to produce a fused cell body.
