The DCDC converter provides an output current which is periodically variable over time and includes a control network which generates a variable reference signal for the input current which is substantially smoothed and obtained from the difference between the output voltage and a reference voltage. A reference image is shifted by the candidate motion vectors obtained from the phase plane correlation. , to an inhibitory peptide or CPP inhibitor which specifically binds to p53 having an aberrant conformation and inhibits p53 amyloidogenic aggregation or restores proper folding of the misfolded protein. 25 \u03bcm or less in terms of arithmetical mean roughness. When necessary, the microprocessor of the DVD section instructs the microprocessor of the television section to switch a receiving channel of the tuner.
