An optical system capable of outputting hi-contrast images and multi-primary color or 3-dimensional images is provided. Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens 36 and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid 37. The S-polarized light is transmitted through a wavelength spectral filter 39 to select red/green/blue light components R1, G1, B1 of 615, 515, 450 nm in wavelength, which are then modulated by a Y1 device 44. The P-polarized light is transmitted through a wavelength spectral filter 46 to select red/green/blue light components R2, G2, B2 of 650, 550, 475 nm in wavelength, which are then modulated by a Y2 device 51. The 3-primary color lights modulated by the Y1/Y2 devices 44, 51 are combined with each other at a PS composite wire grid 55 to project a synthetic light on a screen.

An illumination device has a light guide plate, a sheet section, and a frame. Each optical sheet has projections. The sheet section has a plurality of secured parts each formed by one of the projections or by a plurality of the projections overlapping each other, and the sheet section is secured to the frame at the respective secured parts by a fixing member provided on the side of the sheet section opposite to the light guide plate. The number of projections included in each of the secured parts is fewer than the number of the plurality of optical sheets forming the sheet section.

An optical system attaining a nearly double resolving power in spite of one projector and also eliminating a convergence device is provided. The system includes an 1:1 relay lens in place of a projector lens of a RGB split-combine projection system, and a quarter-wave plate for P-S polarization separation.

The S-polarized light is modulated by a luminance signal Y1 at a Y1 device. The P-polarized light is modulated by a luminance signal Y2 at a Y2 device. The lights modulated by the Y1/Y2 devices are combined with each other at a PS composite wire grid to project a synthetic light on a screen.

摘要:
A magnetic recording medium wind-up method for winding up a long strip-like magnetic recording medium into a coil around a core comprises the steps of pressing the wound-up portion of the magnetic recording medium toward the core with a predetermined pressure while the magnetic recording medium is being wound up around the core. A predetermined length of the magnetic recording medium is wetted, which length will be wound up around the core immediately before the core is fully loaded with the magnetic recording medium, immediately before the predetermined length of the magnetic recording medium is wound up.
摘要:
A liquid crystal display device for an overhead projector has a light-transmissive liquid crystal display cell sandwiched between protective plates both from above and below. At least one of these protective plates is separated from the cell surface to form an air passage provided with a fan such that air can be caused to flow therethrough and come into direct contact with the cell. The cell can thus be cooled efficiently and the light of the projector can be increased for projecting a clearer image.
