  • Patent number: 6645021
    Abstract: A cowling assembly for an outboard motor includes an improved construction that can supply relatively cool air containing little water to the induction device and can also supply air to cool engine components without reducing the charging efficiency. The outboard motor has an engine that includes an air induction device and is enclosed within the cowling. The cowling assembly defines a closed cavity in which the engine is contained and has an air intake system. An air intake duct structure introduces air into the cavity. The intake duct structure includes a plurality of relatively narrow connection passages and has an expansion chamber portion disposed on the downstream side of the passages. Intake noise is reduced by this construction. In one preferred form, the cowling assembly additionally has a second intake system. One or more connection passages communicate with the first air intake system and the second air intake system.

  • Patent number: 6358105
    Abstract: An improved cowling arrangement for an outboard motor powered by an internal combustion engine. The improved arrangement includes a flywheel cover and cowling that incorporate upwardly and downwardly extending ribs which are positioned along an air path between the air vent of the outboard motor and the throttle body of the motor. These ribs act as labyrinth-type seals which prevent water entering the air vent from contacting the throttle body. Also disclosed is an improved cowling arrangement that prevents water pooled on the flywheel cover from draining onto the throttle body when the motor is tilted, such as when the watercraft banks into a turn.

  • Patent number: 6070232
    Abstract: A fault tolerant computer which executes the cache flush operation at a high speed and has the real time characteristic. A processor module is equipped with a cache memory so that the entry address of the updated cache block within the cache memory is stored in a stack. The cache flush is effected only with respect to the entry address in the stack when a recovery-point setting condition due to a timer or the like is satisfied. A memory module has an arrangement doubled in the same storage physical space and is equipped with a buffer memory for temporarily storing the transferred cache block, so that the cache block is simultaneously transferred to a pair of buffer memories.
