Patent number: 11421745Abstract: A clutch includes a clutch housing, a drive-side rotation body, a driven-side rotation body, a rolling element arranged between an inner circumferential surface of the clutch housing and the driven-side rotation body, a support member, and grease. The support member holds the rolling element between the inner circumferential surface of the clutch housing and the driven-side rotation body. The grease is located between the inner circumferential surface of the clutch housing and the rolling element. The support member includes a guide arranged on a distal surface of the support member. When the grease is unevenly applied to the inner circumferential surface of the clutch housing, the guide is configured to guide the grease to be evenly applied to the inner circumferential surface of the clutch housing when inserted into the clutch housing.Type: GrantFiled: May 31, 2019Date of Patent: August 23, 2022Assignee: DENSO CORPORATIONInventor: Daisuke Sawamoto

Patent number: 11047433Abstract: This clutch includes an annular clutch housing, a rotationally driven drive-side rotating body, a driven-side rotating body, a rolling body, and a support member. The clutch is configured such that, when the drive-side rotating body starts to rotate when driven, the drive-side rotating body comes into contact with the support member in a rotational direction and presses the rolling body in the rotational direction through the support member, thereby releasing the rolling body from gripping effected by the clutch housing and the driven-side rotating body. The support member includes a load generation section for generating a load which makes it difficult for the support member to rotate about the rotation axis of the drive-side rotating body when at least the drive-side rotating body starts to rotate when driven.Type: GrantFiled: March 9, 2018Date of Patent: June 29, 2021Assignee: DENSO CORPORATIONInventors: Ryosuke Oguri, Shusuke Kijima, Tetsuya Honda, Yoshio Aoki, Hiroyuki Okada, Kenta Suzuki, Nakatsune Shirai, Daisuke Sawamoto, Tomoaki Ozaki

Patent number: 11002322Abstract: A clutch includes a roller arranged between a clutch housing and a driven side rotating body. The roller is rotated about a rotation axis of a drive side rotating body together with the drive side rotating body when the drive side rotating body is rotationally driven. The roller hinders rotation of the driven side rotating body by being sandwiched between the clutch housing and the driven side rotating body when the drive side rotating body is not rotationally driven. The support member sandwiches the roller between the clutch housing and the driven side rotating body. The support member rotates about the rotation axis of the drive side rotating body together with the drive side rotating body. The grease is arranged between the clutch housing and the roller. The support member restricts rotation of the roller about a central axis of the roller.Type: GrantFiled: September 14, 2017Date of Patent: May 11, 2021Assignee: DENSO CORPORATIONInventors: Ryousuke Oguri, Nakatsune Shirai, Tomoaki Ozaki, Shusuke Kijima, Kenta Suzuki, Daisuke Sawamoto, Akiyoshi Ohara, Hiroyuki Okada

Patent number: 10774259Abstract: An encapsulated agent includes a central part and an outer part that covers a surface of the central part. The central part contains a viscosity-reducing material that reduces viscosity of a fluid to be used in a hydrofracturing technique. The outer part contains a plurality of particulate substances and a holding material that holds the plurality of particulate substances and enables gradual release of the central part in the fluid. The outer part involves distribution of the plurality of particulate substances that allows a content to have one or more local maxima in a direction away from the central part.Type: GrantFiled: July 29, 2016Date of Patent: September 15, 2020Assignee: ADEKA CORPORATIONInventors: Masatoshi Homma, Kazuyuki Noda, Hirokatsu Shinano, Kensaku Akimoto, Daisuke Sawamoto
