Patent number: 11817289Abstract: As a device for correcting positive spherical aberration of an electromagnetic lens for a charged particle beam, a spherical aberration correction device combining a hole electrode and a ring electrode is known. In this spherical aberration correction device, when a voltage is applied between the hole electrode and the ring electrode, the focus of the charged particle beam device changes due to the convex lens effect generated in the hole electrode. Therefore, in a charged particle beam device including a charged particle beam source which generates a charged particle beam, a charged particle beam aperture having a ring shape, and a charged particle beam aperture power supply which applies a voltage to the charged particle beam aperture, the charged particle beam aperture power supply is configured to apply, to the charged particle beam aperture, a voltage having a polarity opposite to a polarity of charges of the charged particle beam.Type: GrantFiled: April 20, 2022Date of Patent: November 14, 2023Assignees: Hitachi High-Tech Corporation, Japan Fine Ceramics CenterInventors: Tsunenori Nomaguchi, Shunichi Motomura, Tadahiro Kawasaki, Takeharu Kato, Ryuji Yoshida

Patent number: 11164716Abstract: When using a charged particle beam aperture having a ring shape in a charged particle beam device, the charged particle beam with the highest current density immediately above the optical axis, among the charged particle beams is blocked, so that it is difficult to dispose the charged particle beam aperture at the optimal mounting position. Therefore, in addition to the ring-shaped charged particle beam aperture, a hole-shaped charged particle beam aperture is provided, and it is possible to switch between the case where the ring-shaped charged particle beam aperture is disposed on the optical axis of the charged particle beam and the case where the hole-shaped charged particle beam aperture is disposed on the optical axis of the charged particle beam.Type: GrantFiled: March 29, 2018Date of Patent: November 2, 2021Assignees: Hitachi High-Tech Corporation, Japan Fine Ceramics CenterInventors: Shunichi Motomura, Tsunenori Nomaguchi, Tadahiro Kawasaki, Takeharu Kato, Ryuji Yoshida

Patent number: 9546801Abstract: A solar-thermal conversion member includes a ?-FeSi2 phase material. The solar-thermal conversion member exhibits a high absorptance for visible light at wavelengths of several hundred nm and a low absorptance for infrared light at wavelengths of several thousand nm and, as a consequence, efficiently absorbs visible light at wavelengths of several hundred nm and converts the same into heat and exhibits little thermal radiation due to thermal emission at temperatures of several hundred ° C. The solar-thermal conversion member may therefore efficiently absorb sunlight, provide heat, and prevent thermal radiation due to thermal emission.Type: GrantFiled: November 9, 2012Date of Patent: January 17, 2017Assignees: Toyota Jidosha Kabushiki Kaisha, Japan Fine Ceramics Center, Kabushiki Kaisha Toyota JidoshokkiInventors: Akinori Sato, Yoshiki Okuhara, Seiichi Suda, Daisaku Yokoe, Takeharu Kato, Toru Sasatani
