  • Patent number: 12006997
    Abstract: A damper device including an input element to which a torque from an engine is transmitted; an output element; an elastic body to transmit torque between the input element and the output element; and rotary inertia mass damper having a mass body that rotates in accordance with a relative rotation of the input element and the output element. The output element is coupled to a rotor of an electric motor, which is coupled to an input shaft of a transmission. The rotary inertia mass damper includes a planetary gear mechanism having a carrier that supports pinion gears, the carrier is a part of the input element, one of the sun gear and the ring gear is a part of the output element, and the other of the sun gear and the ring gear functions as the mass body.

  • Patent number: 7350927
    Abstract: The present invention includes a reflection portion which light-modulates three primary color lights by three rectangular reflective liquid crystal light modulators, then color-combine the light-modulated lights and reflects the resultant light; and a projection lens which projects the reflected color-combined light onto a plane mirror. The three reflective light modulators are arranged in such a manner that their long side directions coincide with a perpendicular direction, and two of the three reflective light modulators are arranged in such a manner that their short side directions become parallel with a projecting direction of image light from a color separation/combination optical system.

  • Publication number: 20060066814
    Abstract: The present invention includes a reflection portion which light-modulates three primary color lights by three rectangular reflective liquid crystal light bulbs, then color-combine the light-modulated lights and reflects the resultant light; and a projection lens which projects the reflected color-combined light onto a plane mirror. The three reflective light bulbs are arranged in such a manner that their long side directions coincide with a perpendicular direction, and two of the three reflective light bulbs are arranged in such a manner that their short side directions become parallel with a projecting direction of image light from a color separation/combination optical system.
