    摘要: A starter driving semiconductor switch apparatus energizes and de-energizes a starter according to a command from an outside. A series circuit to which semiconductor switches are connected in series is provided between a battery serving as a power supply and the starter. The starter is energized by bringing all the semiconductor switches into conduction. A voltage or a current at a predetermined point in the series circuit is monitored to make a self-diagnosis on whether the starter is allowed to start and whether there is a failure in the semiconductor switches according to a monitor output. The starter driving semiconductor switch apparatus is thus expected to have a longer useful life by energizing the starter not by using mechanical contacts but by using semiconductor switches.

    摘要: Provided are an illumination optical system allowing light beams to be condensed and enter an illumination area at different angles from each other, color separating elements that separate colors of the light beams from the illumination optical systems, liquid crystal light valves that modulate the color lights to form image light for the right and the left eyes, a color combining element that combines the color light beams, a wavelength-selective polarization rotating element that rotates the polarization direction of a predetermined color light so as to align the polarization direction with that of a light beam of another color, and a projection lens that magnifies and projects images. The liquid crystal light valves are provided with an incident side microlens array that causes the light beams for the right and the left eyes to pass respectively through the right and the left eye image pixels, and an exit side microlens array that condenses the light that has passed through the pixels. The projection lens is provided with a polarized light separating element that causes the polarization directions of image light for the right and the left eyes to be orthogonal to each other. Using one projection-type display apparatus, a highly efficient stereoscopic image can be displayed with little flicker and cross talk of image light for the right eye and for the left eye.
