Publication number: 20240103277Abstract: This optical waveguide detection element includes a substrate, an optical waveguide layer formed on the substrate, and a photodetector. The optical waveguide layer includes a first optical waveguide in which visible light having a wavelength of 380 nm to 800 nm propagates, a second optical waveguide in which near-infrared light having a wavelength of 801 nm to 2000 nm propagates, and a third optical waveguide in which light propagates to a light receiving surface of the photodetector. A visible light output port of the first optical waveguide from which the visible light is output, a near-infrared light output port of the second optical waveguide from which the near-infrared light is output, and a reflected light input port of the third optical waveguide to which the near-infrared light is reflected and returned are arranged on one end surface of the optical waveguide layer.Type: ApplicationFiled: September 26, 2023Publication date: March 28, 2024Applicant: TDK CORPORATIONInventors: Hideaki FUKUZAWA, Tomohito MIZUNO, Tetsuya SHIBATA, Tsuyoshi KOMAKI

Patent number: 10952510Abstract: There is provided a hook-and-loop fastener manufacturing method. Injection molding is performed to form a molded product in which a pillar group and a base plate having a surface from which the pillar group protrudes are integrated into a unified body. A tip part of the pillar group is cut to form a cut product in which a small pillar group shorter than the pillar group and the base plate are integrated into a unified body. A tip part of the small pillar group is melted to form pillar body portions which are non-melted portions and engaging portions which are melted portions and thicker than the pillar body portions from small pillars. The engaging portions are cooled to determine shapes of a plurality of engaging elements including the pillar body portions and the engaging portions.Type: GrantFiled: October 31, 2018Date of Patent: March 23, 2021Inventors: Tetsuya Fukuzawa, Yasuaki Funo, Yoshitomo Iyoda, Wanli Zhang

Patent number: 10820719Abstract: There is provided a cover-material fixing tool. A cover-material fixing end member is configured to be attached on a cover-material. A clip is configured to be attached on a cover-material fixing end member. The cover-material fixing end member includes a tape member, a clip locking member, and a plurality of stoppers. The clip includes a locking portion for holding the clip locking member to allow the clip locking member to move in a longitudinal direction, and a locking protrusion protruding toward the clip locking member and configured to abut against the stoppers. The clip is movable between the adjacent stoppers to allow position adjustment thereof.Type: GrantFiled: March 23, 2016Date of Patent: November 3, 2020Assignee: YKK CorporationInventors: Ryuichi Murasaki, Takefumi Adachi, Genta Matsumura, Tetsuya Fukuzawa, Wanli Zhang, Hikaru Okuyama
