  • Patent number: 7637249
    Abstract: A fuel injection control apparatus is provided with a fuel injection nozzle, a crank angle detector, a timer, and a control computer. The crank angle detector outputs a pulse signal corresponding to each tooth portion of a signal rotor and a pulse signal corresponding to a tooth missing portion. The control computer sets, as a fuel injection timing, a point of time at which a predetermined standby time period has elapsed from a point of time at which a reference tooth portion is detected. The control computer recognizes a tooth missing zone based on the pulse signal corresponding to the tooth missing portion. The control computer determines whether the fuel injection timing is set in a specific section in the tooth missing zone. When the fuel injection timing is set in a section outside the specific section, the control computer sets, as the predetermined standby time period, a remaining time period shorter than one inter-signal time period.

  • Patent number: 7527039
    Abstract: A fuel injection control apparatus of an internal combustion engine is disclosed. This apparatus is provided with a crank angle detector that includes a signal rotor having a number of tooth portions and a toothless portion. The crank angle detector outputs a first signal corresponding to each tooth portion and a second signal corresponding to the toothless portion. A control computer selectively carries out a first calculation process for calculating the timing of fuel injection using the first signal and a second calculation process for calculating the timing of fuel injection using the second signal. When carrying out the second calculation process, the control computer calculates the timing of fuel injection using the length of time gained by dividing the length of time gained through detection of the toothless portion by the number of tooth portions which can be aligned in the toothless portion.

  • Patent number: 7474734
    Abstract: A void or particle content is determined using the X-ray small angle scattering measurement for a sample made of a thin film having voids or particles disorderly dispersed in the matrix, the diffraction peaks being not available for such a sample. The invention includes three aspects. The first aspect is that an equipment constant is determined and an unknown void or particle content is calculated based on the equipment constant. The second aspect is that a plurality of samples having unknown matrix densities are prepared, the matrix densities are determined so that differences in the matrix densities among the samples become a minimum, and a void or particle content is calculated based on the matrix density and the scale factor of the X-ray small angle scattering. The third aspect is for a plurality of samples having unknown particle densities, and executes procedures similar to those of the second aspect.
