Patent number: 10024280Abstract: A vessel includes a vessel body, an engine contained in the vessel body, an air intake box including an air intake port and that is attached to the engine, an air intake duct drawn around in the vessel body, and a guide duct including an opening that opposes the air intake port. The air intake box supplies air taken in from the air intake port to the engine. The air intake duct includes an outer end connected to a deck of the vessel body. The guide duct guides air taken in from outside the vessel body by the air intake duct to the opening.Type: GrantFiled: July 5, 2017Date of Patent: July 17, 2018Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Hirofumi Anma, Kenichi Otsuka, Satoru Suzuki

Patent number: 9926062Abstract: A jet propelled watercraft includes a reverse gate that moves to a first position and to a second position. When the reverse gate is in the first position, the reverse gate causes a vessel body to move forward. When the reverse gate is in the second position, the reverse gate causes the vessel body to decelerate or move backward. A velocity mode selector is used to select a normal mode or a velocity mode. The velocity mode has a maximum velocity different from that of the normal mode. When the reverse gate is in the second position and the velocity mode is selected, a controller is configured or programmed to set an upper limit of an engine rotation speed in the velocity mode to be different from that of the engine rotation speed in the normal mode.Type: GrantFiled: March 17, 2017Date of Patent: March 27, 2018Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Hirofumi Anma

Patent number: 9623943Abstract: A jet propulsion boat includes a boat body, a jet propelling apparatus configured to propel the boat body, an engine configured to drive the jet propelling apparatus, and an ECU. The ECU is configured or programmed to determine that a deceleration operation is performed when an amount of operation of a first accelerator operation section is greater than an amount of operation of a second accelerator operation section. The ECU sets an upper limit value for the number of revolutions of the engine to a first predetermined value if the boat body is in a first speed traveling state and the boat body is in a turning state.Type: GrantFiled: February 20, 2015Date of Patent: April 18, 2017Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Hirofumi Anma

Patent number: 9193420Abstract: A jet propelled watercraft includes a vessel body, a jet propulsion mechanism, an engine, at least one switch, and an emergency contact unit. The at least one switch includes an engine stop switch, a lanyard switch, and a rollover switch. The engine stop switch is configured to stop the engine in response to manual operation. The lanyard switch is configured to stop the engine in response to detachment of a lanyard. The rollover switch is configured to stop the engine in response to rollover of the vessel body. The emergency contact unit includes a determination portion and an instruction portion. The determination portion determines whether or not rescue is required based on the status of the at least one switch when the engine has been stopped. The instruction portion instructs transmission of a distress signal to a predetermined emergency contact when the determination portion has determined that rescue is required.Type: GrantFiled: September 3, 2014Date of Patent: November 24, 2015Assignee: Yamaha Hatsudoki Kabushiki KaishaInventor: Hirofumi Anma

The ECU is configured or programmed to determine that a deceleration operation is performed when an amount of operation of a first accelerator operation section is greater than an amount of operation of a second accelerator operation section. The ECU sets an upper limit value for the number of revolutions of the engine to a first predetermined value if the boat body is in a high speed traveling state and the boat body is in a turning state, whereas the ECU sets the upper limit value for the number of revolutions of the engine to a second predetermined value which is greater than the first predetermined value if the boat body is in a high speed traveling state but the boat body is not in the turning state.Type: ApplicationFiled: February 20, 2015Publication date: August 27, 2015Inventor: Hirofumi ANMA

Publication number: 20050024258Abstract: An on-vehicle apparatus for recognizing objects is provided. The apparatus comprises a transmission/reception unit, detection unit, estimation unit, and specification unit. The transmission/reception unit transmits a medium wave toward a desired directional range from the vehicle and receives reflected waves of the medium wave and the detection unit detects objects existing in the desired directional range on the basis of the reflected wave. The estimation unit estimates a possibility that each detected object has been detected based on a reflected wave from a first part (e.g., cabin) of a further vehicle other than a second part (e.g., rear part) of the further vehicle, the first part being other than the second part that is the closest in distance to the apparatus-mounted vehicle. The specification unit specifies the second part as an object to finally be recognized of the apparatus-mounted vehicle depending on an estimated result by the estimation unit.Type: ApplicationFiled: July 29, 2004Publication date: February 3, 2005Inventors: Keiji Matsuoka, Hideki Kitagawa, Hirofumi Anma, Atsushi Kawakubo, Tomoya Kawasaki
