    • Provided is a driving method of a mode-locked semiconductor laser device comprising a laminated structure in which a first compound semiconductor layer, a third compound semiconductor layer having an emission region and a second compound semiconductor layer are successively laminated, a second electrode, and a first electrode. The laminated structure is formed on a compound semiconductor substrate having polarity, the third compound semiconductor layer includes a quantum well structure having a well layer and a barrier layer. The well layer has a depth of 1 nm or more and 10 nm or less. The barrier layer has an impurity doping density of 2×1018 cm−3 or more and 1×1020 cm−3 or less. An optical pulse is generated in the emission region by passing a current from the second electrode to the first electrode via the laminated structure.

    • A starting device for feeding a quantity of fuel from the fixed-quantity fuel chamber to an intake passage during start-up having a manually operated primary pump for suctioning/pumping fuel and arranged on a fuel introduction path connected along a fuel-feeding path; and a fixed-quantity fuel chamber for temporarily storing fuel delivered from the primary pump. An internal wall of the fixed-quantity fuel chamber undergoes elastic displacement, allowing its internal capacity to expand/shrink within a predetermined range; the fixed-quantity fuel chamber is connected to a fuel delivery path that communicates with the intake passage side and has a manually operated open/close valve; the valve is opened in a state in which, due to the primary pump being operated, the fixed-quantity fuel chamber is filled with a predetermined quantity of fuel while enlarging its internal capacity, whereby it shrinks due to an elastic contraction force and the fuel.
