A Miller compensated voltage regulator, adapted to be supplied with power from a voltage supply, and having an input port and an output port. A program pulse is generated according to the latched data and is applied to a memory element at a state corresponding to the multi-value data. As a result, the temperatures of semiconductor chips arranged along the coolant flow direction are closer to each other. The HDR composing section composes the image regions each clipped by the image clipping section to generate data of plural composite images having a wider dynamic range than the image captured by the image capturing section. Colored microparticles are constructed with specific electromagnetic absorption andor structural properties that facilitate changing andor removing tissue markings made using the microparticles by applying specific energy to the tissue marking site. The package surrounds a bottom and side of the PCB, and dissipates heating of the active layer, which is transferred from the electrode pad of the photomixer chip to the PCB, to outside.
