Abstract: A vessel propulsion apparatus includes an exhaust passage guiding an exhaust, discharged from combustion chambers into an exhaust collecting passage, to a catalyst housed in a catalyst housing passage, and a cooling water passage guiding cooling water. The cooling water passage includes an upstream water passage, guiding the cooling water taken into the interior of the vessel propulsion apparatus by a water pump, and a first and second parallel water passage connected in series to the upstream water passage and connected in parallel to each other. The cooling water passage supplies the cooling water from the upstream water passage to each of the first and second parallel water passages to cool the catalyst housing passage by the first parallel water passage disposed along the catalyst housing passage and cool the exhaust collecting passage by the second parallel water passage disposed along the exhaust collecting passage.

Abstract: A V-type engine includes two exhaust manifolds connected to two cylinder banks. First and second exhaust ports, respectively provided in the two cylinder banks, are disposed at an inner side of V-shaped lines. Each exhaust manifold includes N branch pipes and a collecting pipe, where N is an integer not less than 2. The N branch pipes are respectively connected to N exhaust ports including at least one of the first exhaust ports and at least one of the second exhaust ports. The collecting pipe is disposed adjacent to N cylinders that are aligned in a direction parallel or substantially parallel to a crank axis direction and extends from one end to the other end of the N cylinders.

Abstract: In a communication control method, a target SIR setting part controls downlink transmission power from a base station so that the T-SIR will be equal to the SIR measured in a known inner loop, by increasing a target signal interference ratio (T-SIR) by a first predetermined value when a reception field level of a common pilot channel before the establishment of synchronization of a dedicated control channel, which is provided by the quality measurement part, falls below a first threshold selected by a target quality setting part depending on the reception quality of a DPDCH, and decreasing the target signal interference ratio (T-SIR) by a second predetermined value when the reception field level of the common pilot channel exceeds a second threshold selected by the target quality setting part depending on the reception quality of the DPDCH.
