Patent number: 12222700Abstract: A controller includes a calculator, a generator, and an adjuster. The calculator calculates a correction value for a position command based on a transmission delay and a control delay included in outputting the position command from the controller to the slave axis drive. The transmission delay is a delay in transmitting the position command to the slave axis drive. The control delay is a delay in the slave axis drive. The generator generates a corrected position command by applying the correction value to a reference position command for the slave axis drive calculated using position information about the master axis drive. The adjuster adjusts, in a predetermined period from when a speed of the master axis drive changes, the correction value to be below a value calculated by the calculator to cause a position of the slave axis drive to avoid exceeding a position of the master axis drive.Type: GrantFiled: March 5, 2020Date of Patent: February 11, 2025Assignee: OMRON CORPORATIONInventors: Yuto Yasui, Junji Shimamura, Masahiko Nakano, Takafumi Okura, Tomonori Shimamura

Publication number: 20190137578Abstract: A magnetic sensor includes a substrate that has a main surface, a free layer that has a magnetic easy axis in an in-plane direction parallel to the main surface, an intermediate layer that is disposed between the substrate and the free layer, and a fixed layer that is disposed between the substrate and the intermediate layer. The fixed layer includes: a first ferromagnetic layer a magnetization direction of which is fixed in a first direction that is nonparallel to the main surface; a second ferromagnetic layer a magnetization direction of which is fixed in a second direction in which a component of a direction parallel to a normal line of the main surface is opposite to the first direction; and a nonmagnetic layer that is disposed between the first ferromagnetic layer and the second ferromagnetic layer.Type: ApplicationFiled: December 27, 2018Publication date: May 9, 2019Inventors: Takamoto FURUICHI, Kenichi AO, Yasuo ANDO, Mikihiko OOGANE, Takafumi NAKANO

Patent number: 9905752Abstract: A magneto-resistance element includes a resistance variable layer and a trap layer. The resistance variable layer includes the alloy having B. A resistance of the resistance variable layer changes according to a magnetic field. The trap layer is for trapping the B diffused from the resistance variable layer. With this structure, the B in the resistance variable layer becomes easily trapped in the trap layer and becomes difficult to be diffused to an outside of the magneto-resistance element. A difficulty associated with B diffusion to the outside of the magneto-resistance element can be prevented from occurring.Type: GrantFiled: August 8, 2014Date of Patent: February 27, 2018Assignees: DENSO CORPORATION, TOHOKU UNIVERSITYInventors: Toshifumi Yano, Kenichi Ao, Yasuo Ando, Mikihiko Oogane, Takafumi Nakano

Patent number: 9753100Abstract: A magnetic sensor includes a magnetization fixed layer, a magnetic field detecting layer, and an intermediate layer. The magnetization fixed layer is formed into a thin-film shape, and a magnetization direction of the magnetization fixed layer is fixed in a direction parallel to an in-plane direction. A magnetization direction of the magnetic field detecting layer changes depending on an external magnetic field. The intermediate layer is disposed between the magnetization fixed layer and the magnetic field detecting layer, and a resistance value of the intermediate layer changes depending on an angle between the magnetization direction of the magnetization fixed layer and the magnetization direction of the magnetic field detecting layer. A magnetization amount per unit area of the magnetic field detecting layer is less than 0.2 [memu/cm2].Type: GrantFiled: February 23, 2015Date of Patent: September 5, 2017Assignees: DENSO CORPORATION, TOHOKU UNIVERSITYInventors: Toshifumi Yano, Kenichi Ao, Takamoto Furuichi, Yasuo Ando, Mikihiko Oogane, Takafumi Nakano

Patent number: 5097762Abstract: The known keyless printing press including an ink feeder section consisting of an ink source roller, a transfer roller, a doctor roller, an anti-hysteresis doctor disposed on the circumferential surface of the doctor roller and the like, and also provided with a wetting device for a plate drum, is improved in order to realize a fresh condition of the ink source roller which is free from residual ink before printing ink having a uniform moisture content is applied thereto. The improvements reside in that a refresh doctor is disposed on the ink source roller at a position downstream of the nip between the ink source roller and the transfer roller for scraping residual ink from the circumferential surface of the ink source roller.Type: GrantFiled: August 23, 1989Date of Patent: March 24, 1992Assignees: Mitsubishi Jukogyo Kabushiki Kaisha, Ryomei Engineering Co., Ltd.Inventors: Takafumi Nakano, Akikazu Seo, Hiromitsu Soeda, Masataka Hirota

Patent number: 5007341Abstract: A keyless printing press includes a delivery nozzle disposed in opposition to an ink source roller and provided with a plurality of delivery ports aligned in parallel along the axial direction of the ink source roller. Printing ink circulating through an ink circulation system is delivered and fed through the respective delivery ports of the delivery nozzle to the ink source roller. The arrangement is improved to obviate the shortcoming that isolated water may repeatedly circulate through the ink circulation system and accumulate, resulting in lowering of printing depth. At least one ink outflow port, for ensuring that printing ink having a high moisture content proportion will flow out of the delivery nozzle, is provided in the delivery nozzle at a position at a level higher than any of the delivery ports.Type: GrantFiled: August 23, 1989Date of Patent: April 16, 1991Assignees: Mitsubishi Jukogyo Kabushiki Kaisha, Ryomei Engineering Co., Ltd.Inventors: Takafumi Nakano, Akikazu Seo, Hiromitsu Soeda, Kazufumi Sueoka
