Patent number: 11400521Abstract: A cutting insert has a top surface, a seating surface, and an outer peripheral surface. The cutting edge includes a corner cutting edge portion, a first cutting edge portion, and a second cutting edge portion. The top surface includes a first rake face, a second rake face, a third rake face, a front side surface, an upper surface, a first side surface, and a second side surface. A ridgeline between the first side surface and the second side surface is continuous to the upper surface. When seen in a direction perpendicular to the seating surface, a width of a boundary between the front side surface and the third rake face is larger than a width of a boundary between the front side surface and the upper surface.Type: GrantFiled: September 6, 2018Date of Patent: August 2, 2022Assignee: SUMITOMO ELECTRIC HARDMETAL CORP.Inventors: Hideo Maeno, Takahiro Okuno, Naoki Matsuda

Patent number: 11185930Abstract: A cutting edge includes a nose portion, a first cutting edge portion, and a second cutting edge portion. When a boundary between a first inclined portion and a first breaker portion, a boundary between a first step surface and a second breaker portion, a boundary between a second inclined portion and a third breaker portion, and a boundary between a second step surface and a fourth breaker portion are a first position, a second position, a third position, and a fourth position, respectively, the second position is higher than the first position and the fourth position is higher than the third position in a direction perpendicular to the seating surface, and a distance between the first position and the third position is greater than a distance between the second position and the fourth position in a direction parallel to the seating surface.Type: GrantFiled: July 26, 2017Date of Patent: November 30, 2021Assignee: Sumitomo Electric Hardmetal Corp.Inventors: Yosuke Shimamoto, Naoki Matsuda, Hideo Maeno, Junya Okida

Patent number: 11040404Abstract: A cutting insert has a seating surface, an outer peripheral surface, a top surface, and an attachment hole. The cutting edge includes a curved cutting corner edge portion, a first cutting edge portion, and a second cutting edge portion. The top surface includes a first rake face contiguous to the first cutting edge portion, a second rake face contiguous to the second cutting edge portion, and a third rake face contiguous to the cutting corner edge portion and also contiguous to the first and second rake faces. The third rake face has a first region contiguous to the first rake face and a second region contiguous to the second rake face. The first rake face and the first region each have a rake angle which is a positive angle. The second rake face and the second region each have a rake angle which is a negative angle.Type: GrantFiled: September 13, 2019Date of Patent: June 22, 2021Assignees: SUMITOMO ELECTRIC HARDMETAL CORP., BIG DAISHOWA SEIKI CO., LTD.Inventors: Naoki Matsuda, Hideo Maeno, Chikara Kimura, Yoshihiro Kuroda, Takafumi Takami, Junichi Koyama, Masahiro Sasano

Patent number: 7095359Abstract: An ice thickness/drifting velocity observation of sea ice by using an ice thickness measurement sonar and a current meter moored into the sea and a sea ice observation by a high-resolution airborne SAR are synchronously performed, a correlation between a draft profile of sea ice passing over the sonar and an SAR backscattering coefficient profile is calculated, and an ice draft of desired sea ice is calculated from the relational expression and an SAR backscattering coefficient. As the SAR backscattering coefficient, a backscattering coefficient of L-band HV polarization may be used. A backscattering coefficient of X-band VV polarization is preferably used as the SAR backscattering coefficient to detect thin ice having a thickness of not more than approximately 10 cm.Type: GrantFiled: October 31, 2003Date of Patent: August 22, 2006Assignees: National Institute of Informantion and Communications Technology, Incorporated Administrative Agency, Japan Aerospace Exploration Agency, Agency of Industrial Science and TechnologyInventors: Takeshi Matsuoka, Seiho Uratsuka, Makoto Satake, Tatsuharu Kobayashi, Akitsugu Nadai, Toshihiko Umehara, Hideo Maeno, Hiroyuki Wakabayashi, Yasushi Fukamachi, Fumihiko Nishio
