摘要： A reflection mirror of a projection display unit which displays a stereoscopic image through a light polarization glasses, reflects a linearly polarized light emitted from a projection source through a polarizing plate toward a screen. The reflection mirror includes: a glass substrate; a metal film provided on the glass substrate; a first dielectric film provided on the metal film; and a second dielectric film provided on the first dielectric film, wherein each of the first and second dielectric films includes a predetermined thickness and a predetermined refractive index so that a phase difference between a p-polarized light of a reflected light and a s-polarized light of the reflected light is within a range from -45 degree to 45 degree in case of an incident angle of the linearly polarized light being varied from 0 degree to 45 degree.

摘要： A frequency/voltage converting device includes a frequency/voltage converting means for converting a DC voltage corresponding to the frequency of an input signal, a reverse-polarity ripple voltage outputting device for outputting a ripple voltage which is equal in magnitude and reverse in polarity to a ripple voltage contained in the DC voltage output from the frequency/voltage converting means; and an adding device for adding the DC voltage output from the frequency/voltage converting device and the voltage output from the reverse-polarity ripple voltage outputting device. The above arrangement serves to cancel the ripple voltage, thereby obtaining a DC voltage containing no ripple voltage for a sawtooth wave generating device.
