Patent number: 11860346Abstract: A lens 1 has unevenness within an optical effective diameter D of an optical surface 2, an arithmetic mean roughness Ra within the optical effective diameter D of the optical surface 2 is 20 nm or more and 50 nm or less, and an average value of widths W of protrusion portions 3 of the unevenness on an average line C2 of a roughness curve C1 of the optical surface 2 is 1/200 or more and 1/50 or less of the optical effective diameter D of the optical surface 2. The lens 1 is suitably used as a lens that composes a zoom lens or an imaging lens.Type: GrantFiled: June 23, 2021Date of Patent: January 2, 2024Assignee: FUJIFILM CorporationInventors: Kenji Ito, Toshio Sasaki, Masayasu Konishi, Michio Cho

Patent number: 8802426Abstract: A device for assay can evenly develop solution, and performs highly accurate and sensitive measurement. A first device part (10) maintains a second insoluble carrier (12) and a third insoluble carrier (13) in such a manner that they overlap with each other at a detection portion (14) of a first insoluble carrier (11). These three carriers (11), (12) and (13) are housed not in contact with each other. A pressing unit (18) having a pressing surface (18a) that is parallel to the detection portion (14) is provided on an inner surface of the second device part (20) facing the detection portion (14). The pressing surface (18a) is displaced by being pressed toward the detection portion (14), and presses, from the upper side of the first insoluble carrier (11), the second insoluble carrier (12) and the third insoluble carrier (13) onto the first insoluble carrier (11). The first device part (10) and the second device part (20) are joined together.Type: GrantFiled: March 30, 2010Date of Patent: August 12, 2014Assignee: FUJIFILM CorporationInventors: Mikinaga Mori, Junichi Katada, Takayoshi Oyamada, Hideyuki Karaki, Masayasu Konishi, Hiroki Terada
