Patent number: 12387875Abstract: A ferrite magnet includes: a hexagonal ferrite main phase; and a second phase. The second phase is an oxide phase containing: an element A which is at least one selected from the group consisting of Ca, Sr, Ba, Bi, and rare earth elements; a transition metal element T including at least Fe; and an element G which is at least one selected from the group consisting of Si, Al, B, F, K, Na, Li, P, and S. When the total number of atoms of the element A, the transition metal element T, and the element G in the second phase is set to 100 at %, the element A occupies 30 to 80 at %, the element G occupies 15 to 40 at %, and the transition metal element T occupies less than 4 at %.Type: GrantFiled: March 8, 2022Date of Patent: August 12, 2025Assignee: TDK CorporationInventor: Keisuke Kamiya

Patent number: 8388425Abstract: A game device (2) executes a video game in which a hammer image (52) displayed on a display device (4) is moved based on an operational signal. The hammer image (52) corresponds to a controller (3), and the operational signal indicates acceleration detected by an acceleration sensor (21) embedded in the controller (3). Additionally, the game device (2) includes an operation-target object control section (32). The operation-target object control section (32) displays an enlarged hammer image (52?) instead of the hammer image (52) when at least either of the acceleration indicated by the operational signal or moving speed of the controller (3) computed based on the acceleration falls within a predetermined range.Type: GrantFiled: December 18, 2009Date of Patent: March 5, 2013Assignee: Konami Digital Entertainment Co., Ltd.Inventor: Keisuke Kamiya
