Abstract: A display unit displays supplied image information on or through a front glass of a vehicle. A system controller generates and supplies the image information to the display unit. The image information indicates lane guides of the traveling lane, which correspond to a configuration of a traveling lane that is viewed from a view point position of a driver through the front glass. The system controller sets a display color of the lane guides displayed by the display unit to a color, which is distinguishable from a color of a road surface.

Abstract: A liquid injection regulator for use in an injection amount measuring apparatus has seal sections for sealing an injection chamber to be charged with fuel oil and a fuel oil discharge port, respectively, and a control valve having portions thereof which constitute parts of the two seal sections. The control valve departs from the injection chamber to release the two seal sections to thereby discharge the liquid and after completion of the discharge of liquid, returns to the liquid injection chamber while sealing the liquid discharge port to thereby raise pressure in the liquid injection chamber.
