摘要： Two embodiments of compact high performance induction systems for V type engines that include pairs of plenum chambers that extend over the respective cylinder banks. First pairs of runners extend from an inlet opening in each plenum chamber to an outlet opening that communicates with the cylinder of the opposite bank. Second pairs of intake passages are provided which extend from inlet openings in the respective plenum chambers to outlet openings in the cylinders of the adjacent cylinder head. The first intake passages have portions that extend through the other plenum chambers and the second intake passages communicate with the cylinders through these intermediate portions. The intermediate portions are curved and in one embodiment the second intake passages are tangential to these curved portions and in the other embodiment they are radial to it.

摘要： A composite image is generated by combining a gray scale image, referred to as a luminance image, and a depth image respectively representing the plurality of components. In the generated composite image, the shape of the component at a relatively high position among the plurality of components easily remains, and the composite image is useful in confirming such a component.

摘要： A planing boat sailing assisting device includes a sensor and a data processing apparatus mounted on a planing boat. The sensor is configured to obtain not reflected light of laser light applied to a water surface but natural visible light or infrared light coming from the water surface obliquely below the sensor, by using a global shutter. The data processing apparatus obtains data obtained by the sensor, at a frame rate of not lower than FPS and not higher than 100 FPS, and generates wave data related at least to a height of a wave and a time until arrival of the wave based on sets of data obtained by the sensor, at least once every second. The data processing apparatus outputs the generated wave data to at least one of a wave display or a controller.

摘要： A vessel operation system includes a propulsion apparatus to generate a forward thrust or a backward thrust by output of an engine, a throttle actuator to change a throttle opening degree of the engine, a first operator, a second operator, and a controller. When the propulsion apparatus generates a backward thrust, the controller sets a first target value within a range not more than a first upper limit value in accordance with an operation of the first operator and control the throttle actuator so that the throttle opening degree reaches the first target value. The controller sets a second target value within a range not more than a second upper limit value larger than the first upper limit value in accordance with an operation of the second operator and control the throttle actuator so that the throttle opening degree reaches the second target value.

摘要： A water jet propulsion boat includes a hull, a drive source, a power storage, a jet propulsion mechanism, a power generator, and a controller. The hull includes a water inlet, a jet outlet, and a flow path connecting the water inlet and the jet outlet and including at least a main flow path extending from the water inlet to the jet outlet. The drive source is located in the hull, and the power storage supplies power to the drive source. The jet propulsion mechanism includes an impeller in the main flow path and driven by a driving force of the drive source to generate a water flow to generate a propulsive force to the hull. The power generator is located in the flow path and uses the water flow generated by the impeller to generate power. The controller charges the power storage with the power generated by the power generator.

摘要： An axial-gap-dynamoelectric machine includes resin bobbins having positioning protrusions, and a stator core including a base yoke having a plurality of tooth holes and positioning holes. In each tooth hole, a circumferential length of a tooth-hole-radial-direction-outer-end surface is larger than a circumferential length of a tooth-hole-radial-direction-inner-end surface. Each of the plurality of teeth has a columnar shape in which a circumferential length of a tooth-upper surface is larger than a circumferential length of a tooth-bottom surface. The positioning protrusions are inserted in the positioning holes, and press the teeth against the base yoke inward in the radial direction such that the tooth-bottom surface is brought into contact with the tooth-hole-radial-direction-inner-end surface and the tooth-oblique surface is brought into contact with the tooth-hole-circumferential-direction-end surface.

摘要： A joystick outputs an operating signal indicating a tilt amount and a twist direction of the joystick. A controller receives the operating signal and controls a marine propulsion device to output a thrust having a magnitude depending on the tilt amount. The controller changes a rudder angle of the marine propulsion device such that a watercraft turns in a direction corresponding to the twist direction. The controller reduces a speed of changing the rudder angle with an increase in the magnitude of the thrust.

摘要： A suspension structure for an outboard motor and an outboard motor includes a clamp bracket, a main body support having a lowest position in a tilt-down state among portions supporting an outboard motor main body except for the clamp bracket, and a coupling fixed to the main body support and supported turnably about a tilt shaft at a first position and a second position in an axial direction of the tilt shaft. The main body support is between the first position and the second position and parallel to the axial direction of the tilt shaft. In the tilt-down state, the main body support is lower than the first position and the second position, and an imaginary triangle is defined by the first position, the second position, and the main body support as vertices when viewed from a rear.
