Patent number: 10894907Abstract: In the present invention, after a primary coating film is formed by boehmite treatment of the surface of a core particle in a solution comprising Al ions, a secondary coating film is formed by cooling the solution to the supersaturation temperature of the Al ions to cause deposition of a hydroxide of aluminum on the surface of the primary coating film, and an Al oxide film is formed on the surface of the core particle by heat treating the secondary coating film in an oxidizing atmosphere. Consequently, the shell is thickened by the amount of secondary coating film formed, so that the cyclic strength of the capsule can be secured and the composition change of the PCM in the production process is remarkably suppressed.Type: GrantFiled: May 17, 2017Date of Patent: January 19, 2021Assignee: NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITYInventors: Takahiro Nomura, Tomohiro Akiyama, Nan Sheng, Daiki Hanzaki

Publication number: 20200225342Abstract: In this object recognition device, an association between a first object detection result and a second object detection result is taken in a region excluding an occlusion area. When the first object detection result and the second object detection result are determined to be detection results for an identical object, a recognition result of the surrounding object is calculated from the first object detection result and the second object detection result. Thus, occurrences of erroneous recognition of an object can be decreased as compared to a conventional object recognition device of a vehicle.Type: ApplicationFiled: November 13, 2017Publication date: July 16, 2020Applicant: Mitsubishi Electric CorporationInventor: Tomohiro AKIYAMA

Patent number: 10585244Abstract: An optical fiber placement surface has formed thereon width-directional position restricting sections for partially restricting the position of an optical fiber ribbon in a width direction perpendicular to the axial direction of the optical fiber ribbon. A portion other than the width-directional position restricting sections serves as a width-directional position non-restricting section that does not restrict the position of the optical fiber ribbon in the direction perpendicular to the axial direction of the optical fiber ribbon. A pressing member is formed at a portion corresponding to the width-directional position non-restricting section. On the other hand, the pressing member is not formed at positions corresponding to the width-directional positional restricting sections. Thus, the optical fiber ribbon is not pressed at the width-directional positional restricting sections. Portions at which the optical fiber ribbon is not pressed by the pressing member are defined as non-main pressing sections.Type: GrantFiled: November 30, 2017Date of Patent: March 10, 2020Assignee: FURUKAWA ELECTRIC CO., LTD.Inventors: Kenji Mori, Tomohiro Akiyama, Takashi Kuroki

Patent number: 10563108Abstract: In the latent heat storage body (100) according to the present invention, the surface of a core particle (10) composed of a latent heat storage material of a metal or an alloy is coated with an oxidized film of a compositional element of the core particle (10). Hence, the step of separately fabricating the core particle and the oxidized film (20) corresponding to a shell accommodating the core particle and accommodating the core particle inside the shell becomes unnecessary. Further since the core particle exhibits no expansion when transforming from a solid phase to a liquid phase, the component of the melted latent heat storage material stays inside the space covered with the oxidized film and the oxidized film is never damaged. Further, the oxidized film (20) can be made chemically stable.Type: GrantFiled: April 23, 2015Date of Patent: February 18, 2020Assignee: NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITYInventors: Tomohiro Akiyama, Takahiro Nomura, Akihito Sagara, Noriyuki Okinaka, Chunyu Zhu

Patent number: 10497942Abstract: A method for forming catalyst particles, each of which has a core/shell structure, by a Cu-UPD method. Namely, a method of manufacturing a catalyst wherein catalyst particles, each of which has a core/shell structure composed of a shell layer that is formed of platinum and a core particle that is covered with the shell layer and is formed of a metal other than platinum, are supported on a carrier. This method is characterized by comprising: an electrolysis step wherein the carrier supporting the core particles is electrolyzed in an electrolytic solution containing copper ions, so that copper is precipitated on the surfaces of the core particles; and a substitution reaction step wherein a platinum compound solution is brought into contact with the core particles, on which copper has been precipitated, so that the copper on the surface of each core particle is substituted by platinum, thereby forming a shell layer that is formed of platinum.Type: GrantFiled: March 2, 2016Date of Patent: December 3, 2019Assignee: TANAKA KIKINZOKU KOGYO K.K.Inventors: Koichi Matsutani, Takeshi Kaieda, Tomohiro Akiyama

Patent number: 9929505Abstract: A connector includes a first connector and a second connector. The first connector includes a pair of housings and a lever that slidably joins the pair of housings relative to each other. The second connector engages with the first connector by sliding relative to the first connector in an axial direction. The pair of housings includes a supporting portion, temporary locking portions, and a guiding portion. The supporting portion is provided on one of the pair of housings and rotatably supports the lever. The temporary locking portions restrict rotation of the lever.
