Publication number: 20160230688Abstract: 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.Type: ApplicationFiled: September 18, 2014Publication date: August 11, 2016Inventors: Takao NAKANISHI, Hiroaki MIYAZAKI, Terumitsu TAKAHATA

Patent number: 9162744Abstract: 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%.Type: GrantFiled: March 29, 2012Date of Patent: October 20, 2015Assignee: Yanmar Co., Ltd.Inventors: Junichi Hitachi, Naohiro Hara, Takao Nakanishi

Patent number: 6637953Abstract: 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.Type: GrantFiled: May 28, 2002Date of Patent: October 28, 2003Assignee: Fuji Photo Film Co., Ltd.Inventors: Takao Nakanishi, Kenichi Shiba
