摘要： PURPOSE:To obviate generation of cracks in a photosensitive material layer even if the film thickness is increased and to obviate degradation of diffraction efficiency by incorporating a copolymer of vinyl carbazole and vinyl compd. having a specific arom. amine and a halogen compd. into the above-mentioned layer. CONSTITUTION:The copolymer of the vinyl carbazole and the vinyl compd. having the arom. amine expressed by the formula I and/or II and the halogen compd. are incorporated into the photosensitive material layer. (R1; -H, -CH3, R2; arom. group, R3; H, an alkyl group or arom. group, n is >=2 integer). Examples of the arom. group include a phenyl group, naphtyl group, etc., and the examples of the alkyl group include aliphat. alkyl groups such as methyl and ethyl. The generation of the cracks is thereby prevented and the transparency is improved even if the film thickness is large. The volumetric phase type hologram recording medium which is not degraded in the diffraction efficiency as compared to the homopolymer of the vinyl carbazole is thereby obtd.

摘要： PURPOSE:To simplify a pattern forming process, and to make possible to easily form a fine pattern, even in case of dry etching by forming a crystal layer composed of a monomer on a substrate and subjecting a monomer layer to a solid-phase polymerization by pattern-wisely irradiating ionizing radiation rays or corpuscular rays on the monomer layer. CONSTITUTION:The crystal layer composed of the monomer is formed on the substrate, and the monomer layer is subjected to the solid-phase polymerization by pattern-wisely irradiating the ionizing radiation rays or the corpuscular rays to the monomer layer to form a pattern. Namely, as the crystal of the monomer is used for a resist material, and the crystal layer of the monomer is subjected to the solid-phase polymerization by irradiating the ionizing radiation rays or the corpuscular rays to the layer, the high resolving power having less than the unit cell length of a monomer crystal can be expected as the limit of resolution. Thus, the fine pattern is easily formed, without using a developer.

摘要： PURPOSE:To prevent display information in a display element from being read by the other party by selecting suitably plural input display information and displaying it on at least one of the display element or a display part. CONSTITUTION:An observer 1 observes simultaneously display information of a display element 2 and the other party 4 through a luminous flux coupling element 3, and also, selects display information 7 which is prevented from being known to the other party in the input display information 7 from the outside, by an input circuit 5 and displays it on only the display element 2 by a discriminating circuit 6 and a display driving circuit 8, and displays the display information 7 which is allowed to be known to the other party on the display element 2 and a display part 9. In such a way, even when a distance to the other party 4 is continuous, the display information on the display element 2 surface is not read by the other party 4, the display information and a face and an action of the other party 4 can be observed in the same visual field, and also, by selecting suitably the input display information from the outside, it can be displayed on at least one of the display element 2 or the display part 9.

摘要： PURPOSE:To vary a projected image and to facilitate production of the title mirror by impressing the voltage corresponding to the image to be displayed to a piezo-electric material in the state of projecting light to the mirror having the specular face which can be deformed cooperatively with the deformation of the piezo-electric material. CONSTITUTION:The light is projected by using a halogen lamp 3 and a lens 4 to the surface of the gold film 1c of the mirror 1 consisting of an aluminum nitride film 1a, an electrode 1b and the gold film 1c and the reflected light thereof is projected on a black board 2. The projected image is formed when 40V voltage is impressed to the gold paste electrode 1b. The image disappears when the impression of the voltage is suspended. If the impression of the voltage is repeatedly turned on and off, the image appears and disappears accordingly. The projected image is thereby changed and deformed as desired and since the constitution is simple, the production is easy.

摘要： PURPOSE:To obtain a variable focus optical element which is deformed while a spherical face or desired aspherical face is maintained by selecting the initial shape and moduli of elasticity of laminated elastic bodies. CONSTITUTION:The transparent elastic body 1 is housed in a container constituted of a bottom plate 2 and side walls 3 formed of glass, etc. The elastic body 1 is constituted of the 1st elastic body 1-1 and 2nd elastic body 1-2 laminated in the direction of an optical axis (h). An aperture plate 4 as a deforming member to deform the elastic body 1 is freely movably provided on the side walls 3. The element is so constituted that, of the elastic body 1 consisting of the plural elastic bodies, the modulus E1 of elasticity of the 1st elastic body 1-1 on the projection side is larger than the modulus E2 of elasticity of the 2nd elastic body 1-2 adjacent to the 1st elastic body 1-1. The variable focus optical element which is deformed while the spherical face or the desired aspherical face is maintained at all times is thereby obtd. if the initial shapes and moduli of elasticity of the elastic body 1-1 and the elastic body 1-2 are adequately selected.

摘要： PURPOSE:To enable easy and simple impartation of a desired holographic image to the desired part of various objects by providing a hologram film strippably from a base material via a stripping layer which has no specific absorption band in a specific wavelength range on the base material. CONSTITUTION:This hologram has the base material 1 and the volume phase type hologram 2 which is provided via the stripping layer 3 having no specific absorption band in the 400-800nm wavelength range on the base material 1 and on which the desired image strippable from the base material 1 is formed. Since the stripping layer 3 has no specific absorption band in the 400-800nm wavelength range, the intrinsic coloration exhibited by the hologram is distinctly exhibited even if the stripping layer 3 is left on the hologram after a transfer operation. The desired holographic image is thereby easily imparted to the desired part of the various objects with the simple operation.

摘要： PURPOSE:To obtain a resin for an optical element which has a high refractive index and permits the change of the refractive index with the specified Abbe number by incorporating a specific repeating unit therein. CONSTITUTION:This resin has the biphenylene repeating unit expressed by the formula, where X is a halogen selected from chlorine and bromine, n1 is 0-4 integer, Y is a group selected from -OR, -SR, etc., and -TeO2R. R is a group selected from hydrogen, alkyl group, etc., n2 and n3 are 1-5 integer in the sum thereof, n3 is >=1 integer. The resin which has the specified Abbe number and the refractive index ranging 1.57-1.75 is more particularly adequate for said resin, for which an amorphous polymer is more preferable. The nonuniformity of density hence the nonuniformity of the refractive index are resulted if the polymerized chain length having a strong blocking property is formed in the case of a copolymer even if the copolymer is amorphous; therefore, the resin forming the polymerized chain length having a high random property is more adequate.
