  • Patent number: 12095346
    Abstract: In an outboard motor including a vertical electric motor, a cooling structure for the vertical electric motor comprises a cooling oil supply member positioned above the stator and including a plurality of outlets for dropping cooling oil on an upper surface of the stator, the outlets being arranged circumferentially in a coaxial relationship to the stator, and the outlets are configured such that an amount of cooling oil that is dropped on a part of the stator located on a first axis on a plane orthogonal to the vertical axis is smaller than an amount of cooling oil that is dropped on a part of the stator located on a second axis which is orthogonal to the first axis on the plane orthogonal to the vertical axis.

  • Publication number: 20220297814
    Abstract: An outboard engine includes a steering mechanism having a pod propulsion device disposed in water outside a hull; a propulsive drive mechanism that is disposed in the hull and gives a propulsive drive force to the pod propulsion device; and a circulation cooling circuit which has an outward flow path that supplies a cooling oil to the steering mechanism and the propulsive drive mechanism, and an inward flow path which recovers the cooling oil from the steering mechanism and the propulsive drive mechanism, in which the inward flow path and the outward flow path of the circulation cooling circuit communicate with each other inside a case body of the pod propulsion device.

  • Patent number: 10937563
    Abstract: A bus bar unit related to one aspect includes: a first bus bar and a second bus bar. The first bus bar and the second bus bar are arranged side by side in a second direction orthogonal to a first direction as viewed from the first direction. The first bus bar includes, as viewed from the first direction, a first straight line portion, a first inclined portion, and a first bent portion. The second bus bar includes, as viewed from the first direction, a second straight line portion, a second inclined portion, and a second bent portion. In an end surface on a second bus bar side of the first bent portion, a distance between the first bent portion and the second inclined portion is longer than a distance between the first bent portion and the second straight line portion.

  • Publication number: 20080285401
    Abstract: According to one embodiment, there is provided an optical disc apparatus including: a recording unit forming a mark and a space having a predetermined code length by using a laser beam and, thus, recording data on an optical disc; a crest value acquiring unit acquiring a crest value of the mark and the space for each code length from a readout signal of the optical disc; an asymmetry calculation unit calculating asymmetry value for each code length from the crest value; and a recoding parameter determining unit determining, based on a linear characteristic between the asymmetry value for each code length and the recording power level, an optimal recording parameter including an optimal recording power level of the laser beam, the recoding parameter determining unit determining the optimal recording power level to set the asymmetry value for each code length within a predetermined range.
