As the excitation energy decreases, the aperture dilates so as increase the amount of light through the aperture.

A racetrack memory device facilitates the manipulation of a series of domain walls along the racetrack. The racetrack is designed so that the domain wall energy increases and decreases in a continuous fashion between adjacent pinning sites, so that a domain wall does not become stuck between them. The variation in the domain wall energy along the racetrack can be provided by continuous variations of the racetrack's width (while maintaining constant thickness) and/or cross-sectional area (in which the racetrack dimensions are varied in both directions perpendicular to the length of the racetrack). Alternatively, this variation in domain wall energy may be provided by varying the magnetic properties of the racetrack along the racetrack while otherwise keeping the shape and size of the racetrack unchanged. In addition, variations of the racetrack's composition and/or shape can be used.

An engine control unit (ECU) of an internal combustion engine performs energy changing control for changing a charging amount (an upper limit value of charging voltage, charging speed or target energy) to a piezo stack of a piezo injector in accordance with common rail pressure. During the energy changing control, the ECU contracts a command injection period as the target energy charged to the piezo stack increases so that actual injection end timing or valve closing timing of a nozzle portion is unchanged even if the target energy is changed. Meanwhile, the ECU delays command injection timing as the target energy increases so that actual injection start timing or valve opening timing of the nozzle portion is unchanged even if the target energy is changed.
