Patent number: 11773814Abstract: An air intake passage structure includes an outer cover forming an outer wall of an outboard motor, an inner cover disposed inside the outer cover, a first intake port formed in the outer cover, a second intake port formed in the inner cover, an air introduction chamber formed between the outer cover and the inner cover; and an air passage formed inside the outer cover. The air passage includes a first passage part on an upper side of the air introduction chamber, and a second passage part extending downward from the first passage part. The air introduction chamber includes a side portion communicating with the first intake port, and a top portion communicating with the first passage part through an opening formed in the partition wall.Type: GrantFiled: January 25, 2022Date of Patent: October 3, 2023Assignee: HONDA MOTOR CO., LTD.Inventors: Yoshihiro Harada, Tsuyoshi Yoshigasaki, Yuki Hase, Hiroshi Yamamoto, Shogo Yoneyama, Ayaka Yamamoto

Patent number: 11326563Abstract: An outboard engine cover structure that covers an outboard engine and includes an inner cover on an inside and an outer cover on an outside. The structure includes a flow space for air formed between the inner and outer covers, an intake formed in a lower portion of the outer cover and configured to take in outer air to the flow space, a communication port formed in the inner cover in a position above the intake, and configured to cause an inner space of the inner cover accommodating the outboard engine to communicate with the flow space, first ribs arranged between the intake and the communication port in the flow space; and second ribs arranged between the intake and the communication port and positioned closer to the communication port than the first ribs in the flow space.Type: GrantFiled: March 16, 2021Date of Patent: May 10, 2022Assignee: HONDA MOTOR CO., LTD.Inventors: Tsuyoshi Yoshigasaki, Yoshihiro Harada, Yuki Hase

Patent number: 11156136Abstract: A breather device and a snow removal machine having the breather device have a casing into which blowby gas of an engine flows, an air suction port for letting out gas from the inside of the casing, and a gas-liquid separation mechanism for separating moisture contained in the blowby gas. The gas-liquid separation mechanism separates an inlet, which allows the blowby gas to flow in, and the air suction port by a predetermined distance, and has the air suction port positioned above a liquid path through which the moisture flows. A gas path allows the blowby gas to flow from the inlet to the air suction port without passing through an air cleaner element.Type: GrantFiled: August 30, 2018Date of Patent: October 26, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Yuki Hase, Atsushi Moroi, Taiga Takamine, Kaku Okabe

Publication number: 20130230660Abstract: [Problem] To provide a method for producing a quantum crystal of a metal complex encapsulating plasmon metal quantum dots. [Solution] The present quantum crystals are produced by a method characterized in that an aqueous solution of plasmon metal complex made from a ligand and a plasmon metal selected from the group consisting of gold, silver, copper, nickel, zinc, aluminium, and platinum, is prepared and brought into contact with a metal carrier made of a metal or a metal alloy having an electrode potential lower than that of the plasmon metal in the aqueous solution, such that the plasmon metal complex is preciptated as quantum crystals arranged on the metal carrier, resulting in having a plasmon enhancement effect. The metal complex crystals encapsulate metal quantum dots, so that an excellent adsorption capability of sample to be detected, as well as an excellent surface plasmon exitation electrofield enhancement effects, are obtained as a result of the quantum size effect.Type: ApplicationFiled: September 6, 2011Publication date: September 5, 2013Applicant: MYTECH CO., LTDInventors: Yuki Hase, Katsuyuki Hasegawa
