Publication number: 20230008631Abstract: A product purchase system includes a first communication terminal carried by an advertising user, a second communication terminal provided to be movable with a vehicle, and a server. The first communication terminal sends advertisement product information indicating a product worn or held by the advertising user to the server. The second communication terminal sends a product search request including second position information and second time information to the server. The second position information indicates a position of the vehicle when a specific action performed by an occupant in the vehicle is detected while the vehicle is moving. The second time information indicates a clock time when the specific action is detected. The server extracts candidate product information from the advertisement product information, based on the second position information and the second time information. The server then sends the extracted candidate product information to the second communication terminal.Type: ApplicationFiled: June 27, 2022Publication date: January 12, 2023Applicant: SUBARU CORPORATIONInventors: Hiroyuki CHIDA, Takahito INOH, Yosuke OHTOMO, Mitsuo AOKI, Hiroyuki SUZUKI, Kazunori OZAKI, Kazuya TACHIMOTO

Patent number: 9822863Abstract: A differential case includes: two supported parts so supported that a differential case is rotatable around a central axis of the differential chamber; and a flange provided between the supported parts and projecting in an outer diameter direction, and welded with a ring gear. The flange includes a bearing surface and a rounded base disposed on one side of the differential case in an axial direction. The bearing surface is in contact with a surface, of the ring gear, disposed on opposite side of a tooth surface of the ring gear, and the rounded base is coupled in a continuous fashion to the bearing surface. A rounded part that disperses stress, generated at the rounded base by gear reaction force derived from the ring gear, is provided in a region between the flange and one of the supported parts disposed on the one side.Type: GrantFiled: March 22, 2016Date of Patent: November 21, 2017Assignee: SUBARU CORPORATIONInventors: Hiroyuki Chida, Yusuke Shirakawa

Patent number: 7951738Abstract: The present invention provides a process for production of a zeolite separation membrane with satisfactory separation performance. The process for production of a zeolite separation membrane according to the invention is comprising: a seed crystal-attaching step in which: a sealed body (10), which is obtained by sealing both ends of a cylindrical porous body (11) with sealing members (12a, 12b), is immersed from the sealing member (12a) end into a suspension (22) containing zeolite seed crystals; the suspension (22) is allowed to permeate from the exterior of the porous body (11) to the interior thereof; the zeolite seed crystals are thereby attached to the porous body (11); and a seed crystal-attached porous body is obtained; and a zeolite membrane-forming step in which: the seed crystal-attached porous body is contacted with a reaction solution containing the raw material of a zeolite membrane; the zeolite membrane is formed on the porous body (11); and a zeolite separation membrane is obtained.Type: GrantFiled: July 27, 2006Date of Patent: May 31, 2011Assignee: Mitsubishi Chemical CorporationInventors: Hiroyuki Chida, Takehito Mizuno
