Patent number: 11324207Abstract: A dual-bearing reel configured to feed a fishing line forward is disclosed. The dual-bearing reel includes a reel body and a handle. The reel body has a first side plate, a second side plate, and a connecting portion. The first side plate includes a circular portion having a circular shape, and a bulging portion bulging forward and downward from the circular portion. The second side plate is circular and disposed apart from the first side plate. The connecting portion connects the first side plate and the second side plate. The handle is rotatably mounted on the first side plate. A first central axis of the circular portion of the first side plate is offset forward and downward from a second central axis of the second side plate.Type: GrantFiled: January 26, 2021Date of Patent: May 10, 2022Assignee: SHIMANO INC.Inventors: Kunio Takechi, Shoji Nakagawa

Patent number: 10765097Abstract: A dual-bearing reel includes a reel body, a spool, a handle, and a spool shaft. The reel body has a first side plate having a first opening that opens in an axial direction of the spool shaft and through which the spool can pass, a second side plate that faces the first side plate, and a second side cover that is mounted on the second side plate. The spool has a bobbin trunk and a second flange. The handle is rotatably provided on the first side plate side of the reel body. The second side plate has a second opening that opens in the axial direction and a fixing portion for mounting a second side cover member, the fixing portion being provided on a peripheral edge of the second opening and at a position overlapping the second flange as viewed in the axial direction.Type: GrantFiled: December 18, 2018Date of Patent: September 8, 2020Assignees: SHIMANO INC., SHIMANO COMPONENTS (MALAYSIA) SDN. BHD.Inventors: Chun Wee Chew, Shoji Nakagawa, Shingo Aoki, Kotaro Shinzaki, Takashi Saito

Patent number: 6096692Abstract: The present invention relates to a synthetic lubricating oil comprising cyclic ketals or cyclic acetals obtained by a reaction between one or more polyhydric alcohols having an even number of hydroxyl groups of not less than 4 and not more than 10 and one or more specific carbonyl compounds, or one or more ketals or acetals which are reactive derivatives of said carbonyl compounds; a working fluid composition for a refrigerating machine comprising a hydrofluorocarbon and a refrigeration oil containing the cyclic ketals or cyclic acetals; and novel compounds of the above cyclic acetals and a production method thereof. The present invention provides a synthetic lubricating oil which shows a good thermal stability, a good oxidation resistance, no carboxylic acid formation due to hydrolysis and a low hygroscopicity and is inexpensive as well.Type: GrantFiled: February 13, 1997Date of Patent: August 1, 2000Assignee: Kao CorporationInventors: Toshiya Hagihara, Shoji Nakagawa, Yuichiro Kobayashi, Hiroyasu Togashi, Koji Taira, Akimitsu Sakai
