Patent number: 11904971Abstract: A straddled vehicle having an engine unit. The engine unit includes an engine body having a cylinder axis tilting forward, a radiator including a radiator core, a turbocharger including a turbine wheel and a compressor wheel, and an intercooler including an intercooler core. In a side view, at least a part of the intercooler core, a part of the turbine wheel and a part of the radiator core are within an area enclosed by a first connecting line, a second connecting line, an engine-body front-surface and a wheel rear-surface. In an upward-downward or forward-backward direction of the cylinder axis, the intercooler-core upper end is more upward than the turbine-wheel upper end, the intercooler-core front end is more frontward than the turbine-wheel front end, the intercooler-core lower end is more upward than the radiator-core upper end, and the radiator-core rear end is more frontward than both the turbine-wheel rear end and the intercooler-core rear end.Type: GrantFiled: October 22, 2021Date of Patent: February 20, 2024Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Naoki Makita, Hayatoshi Sato, Masaki Torigoshi, Makoto Kuroiwa, Naoto Tajima

Patent number: 9931857Abstract: An expendable supply includes a memory that stores a timing of a last warning after a recommended limit. A warning generator of a printer determines whether to generate a warning upon occurrence of certain operations. The warning generator generates a warning when the last warning generation time is not stored in the memory of the expendable supply upon detection by a printer detector, or upon the last warning generation included in a first time period is stored in the expendable supply memory at the detection by the detector and the first time period has elapsed at the detection by the detector. A warning is not generated upon the timing of the last warning generation included in the first time period is already stored in the expendable supply memory upon detection by the detector and the first time period having not elapsed at the detection by the detector.Type: GrantFiled: January 10, 2017Date of Patent: April 3, 2018Assignee: RISO KAGAKU CORPORATIONInventors: Satoshi Ohtaka, Tomoki Matsumura, Naoto Tajima

Patent number: 9636910Abstract: A printer includes an expendable supply, a detector that detects at least one of a power-on operation, a resume from an energy-saving mode and a new installation of an expendable supply, a determiner that determines whether or not a recommended limit of the expendable supply has passed, a warning generator that generates a warning for notifying that a usable limit of the expendable supply will come soon if the recommended limit has already passed, and a memory storage that stores a warning cycle and a last warning generation. When the recommended limit has passed and the power-on operation, the resume or the new installation is detected, the warning generator generates a warning [1] when the last warning generation is not stored in the memory storage, or [2] when the last warning generation is stored in the memory storage and the warning cycle has elapsed from the last warning generation.Type: GrantFiled: May 22, 2015Date of Patent: May 2, 2017Assignee: RISO KAGAKU CORPORATIONInventors: Satoshi Ohtaka, Tomoki Matsumura, Naoto Tajima
