  • Patent number: 11939035
    Abstract: An outboard motor that significantly reduces or prevents discoloration around an exhaust opening includes an engine, a drive shaft, a propeller shaft, a housing, an exhaust passage, a water intake passage, and a valve. The exhaust passage guides an exhaust gas from the engine toward the discharge chamber inside the housing. The water intake passage guides water, which enters an inside of the housing, to the discharge chamber when a forward propulsive force is generated. The valve regulates passage of the exhaust gas at the first opening due to water pressure when a forward propulsive force is generated. The valve permits the passage of exhaust gas at the first opening due to exhaust pressure when a backward propulsive force is generated.

  • Publication number: 20240092183
    Abstract: A control apparatus, which controls a drive motor that drives a rotor installed in an electrical aircraft, instructs the drive motor to selectively operate in at least two motor-control modes. The at least two motor-control modes include a flying motor-control mode for causing the electrical aircraft to fly, and a cleaning motor-control mode for cleaning the rotor. The control apparatus controls, in the cleaning motor-control mode, the drive motor such that a rotational frequency of the drive motor is lower than a predetermined human-audible frequency range.

  • Patent number: 11921365
    Abstract: An isolator includes a first core, a second core, a nonreciprocal member, and a magnetic body. The first core and the second core extend in a first direction and are positioned side by side with a cladding therebetween in a second direction that intersects the first direction. The nonreciprocal member is in contact with at least a part of the second core while being positioned side by side with the second core in the second direction. In a magnetic field generated by the magnetic body in a portion where the nonreciprocal member is positioned, a component in a third direction perpendicular to the first direction and the second direction is greater than any component other than the component in the third direction.

    Abstract: The purpose of the present invention is to provide a method for producing a 3-hydroxy-3-methylbutyrate or salt thereof, the method being capable of efficiently producing a highly pure 3-hydroxy-3-methylbutyrate or salt thereof. The highly pure 3-hydroxy-3-methylbutyrate or salt thereof can be efficiently produced by performing at least one of the following operations (a) to (d) on a solution containing 3-hydroxy-3-methylbutyrate and impurities exposed to environments of pH 6.0 or less. (a) Hypochlorous acid or salt thereof is added to the solution. (b) The solution is maintained at 40 to 200° C. for 30 minutes or more, provided that the solution contains hypochlorous acid or salt thereof. (c) Calcium salt is added to the solution, and the precipitated calcium 2,3-dihydroxy-3-methylbutanoate is separated from the liquid phase in which 3-hydroxy-3-methylbutyrate and/or the salt is dissolved.
