  • Patent number: 11922030
    Abstract: According to one embodiment, a memory device includes a first nonvolatile memory die, a second nonvolatile memory die, a controller, and a first temperature sensor and a second temperature sensor incorporated respectively in the first nonvolatile memory die and the second nonvolatile memory die. The controller reads temperatures measured by the first and second temperature sensors, from the first and second nonvolatile memory dies. When at least one of the temperatures read from the first and second nonvolatile memory dies is equal to or higher than a threshold temperature, the controller reduces a frequency of issue of commands to the first and second nonvolatile memory dies or a seed of access to the first and second nonvolatile memory dies.

  • Patent number: 6186844
    Abstract: In an outboard motor, a balancer shaft is arranged in a crank chamber substantially in parallel to a crank shaft disposed in an engine unit so as to extend perpendicularly in an operative state of an outboard motor and end portions of the balancer shaft are supported by bearings. The end portions of the crank shaft and the balancer shaft are covered and sealed by a seal member straddling over both the end portions thereof.

  • Patent number: 5474012
    Abstract: Adjustment is made of the position of a marine transportation system including a boat having a drive, a trimmable port tab and a trimmable starboard tab. The operation of the marine transportation system is monitored to provide an output distinguishing boat operation in an on-plane condition and boat operation in an off-plane condition, to provide an output distinguishing boat travel in a straight forward condition and boat travel in a turning condition and to provide an output distinguishing boat operation in a first heel condition in which the boat tilts to port and boat operation in a second heel condition in which the boat tilts to starboard. The port and starboard tabs are positioned at desired positions in response to the outputs. According to the embodiment, a heel adjustment operation of the boat is carried out during boat operation in an on-plane straight forward travel condition, only.

  • Patent number: 4699110
    Abstract: A primary passage and a secondary passage in a parallel relation to each other are disposed between an air cleaner and a branch passage collecting portion of an intake manifold. The primary passage is smaller in diameter than the secondary passage and has at the downstream end thereof a laval nozzle through which air flows at the speed of sound even under low-speed low-load engine operating conditions. The laval nozzle is connected to a carburetion chamber which is elongated straightly in the direction downstream of the laval nozzle. A fuel injection valve is disposed in the primary passage at a place upstream of the laval nozzle. A pressure control valve is adapted so that a vacuum higher than a predetermined value is developed in the carburetion chamber at any time. A primary throttle valve and a secondary throttle valve are interconnected so that the secondary throttle valve is held closed unless the primary throttle valve is fully open.

  • Patent number: 4517134
    Abstract: In a variable venturi carburetor in which the metering jet portion of fuel changes automatically according to the amount of intake air required to keep the mixture at a constant air-to-fuel ratio at all times, two series-arranged nozzles and an auxiliary fuel passage communicating with the downstream side of the venturi and with the space formed between the two nozzles additionally formed at the fixed venturi portion in such a way that the auxiliary fuel passage can be opened or closed according to engine operating conditions. Therefore, when the auxiliary fuel passage is opened, since fuel is introduced into the venturi through only a single nozzle, a rich mixture is obtained; when the auxiliary fuel passage is closed, since fuel is introduced through two nozzles, a lean mixture is obtained.
