摘要： There is provided an optical module in which leaked light or the like from a plurality of optical elements on the same substrate is made less likely to affect adjacent optical elements, and a cross-talk noise can be thereby significantly reduced. The optical module includes an internal waveguide in a first trench of a substrate, a mirror section, and optical elements. A plurality of the first trenches of the substrate are formed independently of each other and substantially in parallel with each other, and lengths of adjacent first trenches from the end surface of the substrate are made different from each other. The optical elements are mounted on the surface of the substrate so as to oppose the minor sections formed at the tip portions of the first trenches having the different lengths.

摘要： A fuel injection amount control apparatus comprises an air-fuel ratio sensor disposed between an exhaust gas merging portion and an upstream catalyst. The control apparatus performs a feedback correction on an amount of fuel to be injected by the fuel injection valve so that an air-fuel ratio represented by the output value of the upstream air-fuel ratio sensor becomes equal to a target air-fuel ratio set at stoichiometric air-fuel ratio. The control apparatus obtains an air-fuel ratio imbalance indicating value, which becomes larger as a difference in air-fuel ratio of each of the mixtures supplied to each of the combustion chambers among the cylinders becomes larger, and performs an increasing correction to the instructed fuel injection amount in such a manner that an air-fuel ratio determined by the instructed fuel injection amount becomes richer than the stoichiometric air-fuel ratio as the obtained air-fuel ratio imbalance indicating value increases.
