Latest Patents

One of Ohtomo's latest patents is an engine speed control apparatus for outboard motors. This apparatus is designed to control the speed of an internal combustion engine installed in an outboard motor. It features an actuator connected to the throttle valve of the engine, which opens and closes the throttle valve. The system includes up/down command signal outputting devices that allow an operator to increase or decrease the engine speed. The engine speed is controlled to change in response to the command signal, with a varying change amount depending on whether the detected engine speed exceeds a reference speed. This innovation enables fine and precise control of the engine speed in the low-speed range, facilitating better speed regulation.

Another significant patent is the outboard engine unit. In this design, the outboard engine body is mounted via a swivel shaft to a stern bracket. An angle sensor is provided on the stern bracket, which outputs detection information indicative of the operating angle of a contact. The curved member on the engine body engages with the contact and has a continuously varying radius of curvature. This design allows the contact to vary in operating angle while sliding along the curved surface, determining the steered angle based on the detection information from the angle sensor.
