In an apparatus for controlling operation of an outboard motor having an engine to power a propeller, a transmission being selectively changeable in gear position to establish speeds including a first speed and second speed and transmitting power of the engine to the propeller with a gear ratio determined by established speed, and a trim angle regulation mechanism regulating a trim angle through trim-up/down operation, the transmission is controlled to change the gear position from the second speed to the first speed when the second speed is selected and a throttle opening change amount is at or above a predetermined value; and the trim angle regulation mechanism is operated to start the trim-up operation based on engine speed. With this, the transmission can be appropriately controlled to suppress the decrease in boat speed caused by change of gear position, thereby mitigating an unnatural feel given to the operator.

In an apparatus for controlling operation of an outboard motor having an internal combustion engine to power a propeller, and a transmission being selectively changeable in gear position to establish speeds including a first speed and a second speed and transmitting power of the engine to the propeller with a gear ratio determined by established speed, engine speed is detected, it is determined whether acceleration is instructed when the second speed is established, and operation of the transmission is controlled to change the gear position from the second speed to the first speed when the acceleration is determined to be instructed, and then change back the gear position from the first speed to the second speed based on the detected engine speed, thereby enabling to control the transmission optimally.
摘要:
A light guide plate shaped substantially like a plate includes a light incident surface, a light exit surface and a reflective surface, which is opposite to the light exit surface, configured to reflect light toward the light exit surface. A plurality of optical units is arranged along the reflective surface in a direction orthogonal to the light incident surface. Each optical unit is shaped substantially like a quadratic prism that is convex toward the reflective surface and has a top surface and two slopes being formed opposite to each other with respect to the top surface. A dimension of the top surface is constant in a direction of arrangement of the optical units and an interval between adjacent optical units becomes greater as the adjacent optical units lie further away from the light incident surface in the direction of arrangement of the optical units.
