Patent number: 12494612Abstract: Provided is a method of bonding an operation wire used in a medical equipment. The method includes: locally heating an adjacent region of a bonding region of an operation wire to generate an oxide in the adjacent region of the operation wire; coating the bonding region and the adjacent region with flux to remove an oxide in the bonding region and the oxide in the adjacent region; inserting a bonding end portion of the operation wire into a through-hole of a coupling material; injecting a melted bonding material into between the coupling material and the operation wire to integrally bond the coupling material and the operation wire such that the oxide remaining in the adjacent region prevents wet-spreading of the bonding material.Type: GrantFiled: May 17, 2023Date of Patent: December 9, 2025Assignee: OLYMPUS CORPORATIONInventors: Takehiro Ishikawa, Keiichi Asami, Tomonori Imamura

Patent number: 10903038Abstract: With strength of an objective lens set to first strength, a first scanned image of a sample is produced. The strength of the objective lens is set to second strength. A rotation amount difference of a charged particle beam between the case where the strength is set to the first strength and the case where the strength is set to the second strength is specified. At the second strength, with a scanner controlled such that the rotation for canceling the rotation amount difference is supplied to the charged particle beam, a second scanned image of the sample is produced. Based on a relative positional relationship between the first and second scanned images, a deflector is controlled such that positions of the first and second scanned images coincide with each other.Type: GrantFiled: January 9, 2019Date of Patent: January 26, 2021Assignee: Shimadzu CorporationInventor: Takehiro Ishikawa

Patent number: 10504685Abstract: Magnetic field strength of a converging lens is repeatedly and alternately changed between first strength and second strength. The information about a first aperture image in the case where the magnetic field strength is the first strength and the information about a second aperture image in the case where the magnetic field strength is the second strength are produced. A first movement instruction for the first and second aperture images is given based on the first information and the second information during repetitive changes of the magnetic field strength. Based on the first movement instruction, a first deflector is controlled. A second movement instruction for the first and second aperture images is given based on the first information and the second information during repetitive changes of the magnetic field strength. Based on the second movement instruction, a second deflector is controlled.Type: GrantFiled: January 9, 2019Date of Patent: December 10, 2019Assignee: Shimadzu CorporationInventor: Takehiro Ishikawa
