    摘要: A display device of projection type capable of projecting an image with well defined image frame is disclosed. The device comprises 3 spatial light modulators on which color image information is written in 3 primary colors respectively and is read out as a combined optical color image in a form of light beam, the light beam is then projected out of the display device through lens groups for forming a projected image on a screen, the device further comprises a mask disposed in a proximity of an imaginary image formation plane arranged to locate in a vicinity of one of the lens groups, the light beam is caused to form an optical image on the imaginary image formation plane. The mask has a variable light shielding configuration controlled either electronically or electro-mechanically for cutting off unnecessary light portions of the light beam carrying the optical image so that an image of high contrast and well defined clear fringe is projected on the screen.

    摘要: To provide a laminated band-pass filter comprising at least two band-pass filters without reducing the Q factor of strip line conductors constituting the band-pass filters. A laminated band-pass filter comprises an integrated device formed by laminating and integrating a plurality of dielectric layers together, a plurality of internal grounding conductors formed inside the integrated device, and two band-pass filters sandwiched between two of the plurality of grounding conductors and formed inside the integrated device. One of the band-pass filters has strip line conductors, and the other has strip line conductors. The two band-pass filters are formed in different areas with a boundary between these areas corresponding to a predetermined cross section substantially perpendicular to the grounding conductors.
