Patent number: 11969803Abstract: According to one implementation, a drill includes the first cutting edges, the second cutting edges and a deflection reducer. The first cutting edges drill a prepared hole to a workpiece. The first cutting edges are formed in a tip side of the drill. The first point angle and each first relief angle of the first cutting edges continuously or intermittently decrease from the tip side toward a rear end side of the drill. The second cutting edges finish the prepared hole. The second cutting edges are formed at positions away in the rear end side from the first cutting edges. The second cutting edges have the second relief angles at a maximum diameter position. The deflection reducer reduces deflection of the second cutting edges by being inserted into the prepared hole. The deflection reducer is formed between the first cutting edges and the second cutting edges.Type: GrantFiled: January 6, 2022Date of Patent: April 30, 2024Assignee: SUBARU CORPORATIONInventors: Masao Watanabe, Ryohei Ono, Tatsuo Nakahata, Hiroyuki Sugawara, Shinya Matsuo, Hideharu Takahashi

Publication number: 20240084753Abstract: A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.Type: ApplicationFiled: November 29, 2021Publication date: March 14, 2024Inventors: Tetsuya NISHIYAMA, Daigo KISHI, Tatsuo NAKANO, Seiichirou TAKAHASHI, Koji SAITO, Yukiyoshi INUTA, Takao ARIMATSU, Yasuhiro ENDO

Patent number: 8720021Abstract: The present invention utilizes jet streams of hot gas at a high efficiency and thereby to increase a bulk of non-woven fabric. Non-woven fabric containing thermoplastic synthetic fibers is subjected to jet streams of hot gas in a thickness direction of the non-woven fabric. A temperature of the jet streams of hot gas used for this process is set to a level lower than the temperature at which a resinous ingredient forming the surface of the thermoplastic begins to be melted. The jet streams of hot gas are directed to penetrate fiber interstices in the non-woven fabric and then to strike on a means serving to divert the jet streams of hot gas.Type: GrantFiled: October 19, 2009Date of Patent: May 13, 2014Assignee: Uni-Charm CorporationInventor: Tatsuo Takahashi
