  • Patent number: 9494094
    Abstract: An engine rotational speed control device (4) includes a noise removal processing unit (6) which corrects a command value, wherein the noise removal processing unit (6) is configured to set a current first output value (B(i)) to be identical to a previous first output value (B(i?1)) in a case where, in a latest step group, the number of successive increase steps is smaller than a first predetermined number (n) and the number of successive decrease steps is smaller than the first predetermined number (n), the increase step is a step in which a current first input value (A(i)) is greater than the previous first output value (B(i?1)) by a first set width (n) or more, and the decrease step is a step in which the current first input value (A(i)) is smaller than the previous first output value (B(i)) by the first set width (n) or more.

  • Publication number: 20160230688
    Abstract: An engine control device includes an engine failure determination unit and a rotation rate control unit. The engine failure determination unit determines whether or not a predetermined failure condition is satisfied based on a result of detection performed by a sensor that detects the state of a marine vessel engine. If an engine rotation rate is higher than a limited rotation rate when the engine failure determination unit determines that the failure condition is satisfied, the rotation rate control unit decreases the engine rotation rate to the limited rotation rate and performs a limited-operation control for rejecting any rotation rate operation that indicates a higher engine rotation rate than the limited rotation rate.

  • Patent number: 9162744
    Abstract: A ship maneuvering device rotates a propeller at a lower rotational frequency than the rotational frequency of the minimum idling speed of an engine. A control device has a crawling speed navigation mode. A crawling speed navigation mode button that selects whether or not to execute the crawling speed navigation mode is connected to the control device. When the crawling speed navigation mode is selected, and the amount of operation of a joystick lever is at or beneath a baseline amount of operation Ms, the control device causes the rotational frequency N of the engine to be the rotational frequency Nlow of the minimum idling speed, and in accordance with the amount of operation of the joystick lever, varies the duty ratio D, which is the fraction of time T1 that a main clutch is engaged in a predetermined cycle T, within a range of no greater than 100%.

  • Patent number: 6637953
    Abstract: A camera is provided with a lens barrier moving between a closed position and an open position. The lens barrier is urged toward the open position by an urging mechanism, and is kept in the closed position by a locking mechanism. The urging mechanism urges the lens barrier with a compression spring. When the lens barrier is moved from the open position to the closed position, a movement amount thereof is reduced by a minimum length of the compression spring compressed in accordance with the movement of the lens barrier. In order to compensate the amount corresponding to the minimum length of the compression spring, a slider is provided. The slider is movable within a predetermined range together with the lens barrier when moving the lens barrier beyond the closed position.
