Patent number: 12292311Abstract: To reduce the influence of an unintended magnetic flux of a permanent magnet on detection accuracy. An absolute encoder (2) includes a magnet provided at a tip end side of any one of a first worm gear portion (11) and a second worm gear portion (22), and an angle sensor configured to detect a rotation angle of the magnet in response to a change in magnetic flux generated from the magnet. In the magnet, a first magnetic pole portion of a first polarity and a second magnetic pole portion of a second polarity different from the first polarity are formed adjacent to each other as viewed from an axial end surface of the magnet. The first magnetic pole portion and the second magnetic pole portion are formed adjacent to each other in a radial direction with a radial center of the magnet as a boundary, and the first magnetic pole portion and the second magnetic pole portion are formed adjacent to each other in an axial direction with an axial center as a boundary.Type: GrantFiled: December 25, 2020Date of Patent: May 6, 2025Assignee: MINEBEA MITSUMI Inc.Inventors: Kaoru Nishiguchi, Yasuo Osada, Takahiro Ohara

Publication number: 20240167117Abstract: A method for producing a hot-rolled steel sheet which enables predicting a temperature history of unevenness of the end face of a coil includes: measuring a surface temperature of hot-rolled strip-shaped steel; calculating a temperature history in a natural cooling state after coiling, assuming that the strip-shaped steel has been coiled without unevenness on an end face, based on the surface temperature measured in the measurement step; actually coiling the strip-shaped steel after the measurement step; scanning with a displacement meter, an end face of a coil formed in the coiling step, and deriving a size of the unevenness of the end face over a radius of the coil; and predicting a temperature history of the unevenness in a natural cooling state using: the temperature history calculated in the first calculation step; and the size of the unevenness derived in the derivation step.Type: ApplicationFiled: June 15, 2021Publication date: May 23, 2024Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Koki FUKUSHIMA, Yuta SANO, Masanori KOBAYASHI, Toma KITAGAWA, Toshio MURAKAMI, Takahiro OHARA, Masahiro INUI, Takeshi IIJIMA, Takashi TERAOKA, Takuma YONEDA, Kohei ODO, Shun HARADA

Publication number: 20240088287Abstract: A semiconductor device includes a semiconductor substrate, a first insulating film formed on an upper surface of the semiconductor substrate in an outer peripheral region so as to surround a cell region in plan view, and a resistive element formed on the first insulating film so as to surround the cell region in plan view. A second insulating film having a thickness thinner than that of the first insulating film is formed on the upper surface of the semiconductor substrate in the outer peripheral region. A dummy pattern is formed from a portion over the second insulating film to a portion over the first insulating film so as to cover a step occurring between the second insulating film and the first insulating film.Type: ApplicationFiled: July 5, 2023Publication date: March 14, 2024Inventors: Takahiro OHARA, Koichi ARAI, Yasunori YAMASHITA, Hideyuki YASHIMA

Publication number: 20230170523Abstract: The invention is a nonwoven fabric characterized by satisfying 0.25?(L2/V)?10, when an average fiber diameter of all fibers is L (?m) and a volume per m2 is V (cm3). The nonwoven fabric leads to a solid electrolyte-carrying sheet in which solid electrolyte particles are carried between fibers and which can achieve a good balance among thickness reduction, powder falling property of the solid electrolyte particles, and electrical conductivity.Type: ApplicationFiled: April 13, 2021Publication date: June 1, 2023Applicant: Nippon Sheet Glass Company, LimitedInventors: Yuji KATAGIRI, Takahiro OHARA

Patent number: 7512319Abstract: In a synchronous information reproduction apparatus, a receiving section sequentially receives a clock signal. A storing section stores object information to be sequentially reproduced from a series of reproduction points. A reproduction point generating section generates location information indicative of a reproduction point of the object information stored in the storing section. A reproducing section reads and reproduces the object information from the storing section based on the reproduction point generated by the reproduction point generating section. A synchronizing section synchronizes an incremental speed of the reproduction point generated by the reproduction point generating section with a reception timing of the clock signal based on a reception time interval of the clock signals. An outputting section outputs contents of the object information reproduced by the reproducing section.Type: GrantFiled: June 14, 2001Date of Patent: March 31, 2009Assignee: Yamaha CorporationInventors: Tsuyoshi Miyaki, Satoshi Sekine, Takahiro Ohara

Patent number: 6555737Abstract: Pictures of a predetermined musical instrument, such as a drum set, and a model player are displayed, so as to visually indicate, in accordance with a progression of performance, which musical instrument should be operated or played and which of body parts, such as left and right hands and feet, should be used for playing the musical instrument. For example, different display colors may be allocated to the left and right hands so that each musical instrument to be played is displayed in such a color corresponding to the hand to be used for playing the musical instrument. A picture of a musical score may be displayed. Performance data and musical score data of a music piece and performance motion picture data may include time data that are based on their respective time scales. In reproduction, the respective time scales of the respective data are commonized to thereby permit synchronization between a reproductive music performance and visual display.Type: GrantFiled: October 3, 2001Date of Patent: April 29, 2003Assignee: Yamaha CorporationInventors: Tsuyoshi Miyaki, Satoshi Sekine, Takahiro Ohara
