Abstract: PROBLEM TO BE SOLVED: To obtain an electrophoretic display device which embodies a memory characteristic stable for a long period of time without depending upon an electrode holding charge and without requiring switching control of an open state. SOLUTION: Colored charge particles 7 dispersed in a colored insulative liquid 6 and an insulative coloring liquid 6 are held within the closed spaces enclosed by a transparent display substrate 1, a counter substrate 2 and partition walls 3. Transparent electrodes 4 are arranged on the transparent display substrate 1 in the respective closed spaces and counter electrodes 5 on the counter substrate 2. The transparent electrodes 4 and? the counter electrodes 5 have fixing surfaces 14 at which the colored charge particle 7 gather. Tacky adhesive layers 8 which allow the repetitive adsorption and peel of the colored charge particles are arranged on the surfaces of these fixing surfaces 14, by which the electrophoretic display device is constituted.

Abstract: PROBLEM TO BE SOLVED: To enable production of an inexpensive minute colored ball by forming a minute colored ball in its semispherical surface by the application of exposing and developping treatment with the use of the photosensitive characteristic of silver halide. SOLUTION: Light is applied for exposure to a part of surface of an opaque photosensitive ball 1 having silver halide. The ball 1 is immersed in a developping solution to form a colored layer 2 on a bright surface of the ball 1 irradiated with the light or on a dark surface thereof not irradiated therewith. Then, the silver halide remaining on the surface thereof is removed by immersing it in a fixer. For example, photosensitive balls 1 in which silver bromide or titanium oxide is contained in a gelatin ball having an average diameter of 50 μm, are used, and these balls 1 are scattered on a black alumite substrate 11, then even exposure is applied from the surfaces thereof (a). Subsequently, a developping treatment is applied (b), and then fixing treatment is applied thereto by the use of sodium thiosulface (c), thereby forming a black colored layer 2.

Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method for electron emission element which can attain a large area and mass production of electron emission elements with high resolution without being affected by sodium during driving the electron emission element over a long time even in the case of manufacturing the electron emission element using blue plate glass. SOLUTION: This method, which is used for manufacturing electron emission elements having an electron emission part 5 between opposing electrodes 2, 3, involves a process which applies metallic compound-containing aqueous solution between the electrodes 2, 3, and a process which heats and burns the metallic compound. The metal compound uses organic metallic complex salt formed out of metal and neutral ligand containing silicon and/or phosphorus in molecule.

Abstract: PURPOSE:To obtain a analyzing method capable of carrying out detection of a target nucleic acid in simple operation and high sensitivity even in the case of a small amount of sample. CONSTITUTION:A sample is made to react with a probe in the presence of two or more kinds of reagent substances causing irreversible change and capable of detecting and accumulating by mutual action through a double helix structure under conditions where formation of hybrid body and dissociation of the formed hybrid body are repeatedly carried out between the target nucleic acid in the sample and the probe. Thereby, irreversible change based on mutual action of these reagent substances is accumulated (amplified) to detect the target nucleic acid.

Abstract: PURPOSE:To obtain a stable labeled protein wherein a cyanine pigment which is hardly water-soluble, is made water-soluble and a protein is labeled with a pigment by a method wherein nitrogen atoms are bonded to carbon and a carboxyl group is bonded to alpha carbon or an adjacent carbon main chain. CONSTITUTION:In a (mero)cryanine pigment provided with a heterocycle provided with nitrogen atoms, the nitrogen atoms are bonded to carbon and a carboxyl group is bonded to alpha carbon or an adjacent carbon main chain. In order to make a cyanine pigment water-soluble and to reduce a change in the wavelength and the stability of the pigment as compared with a case where a polar group is introduced, it is preferable that the polar group is introduced directly to the nitrogen atoms in the heterocycle. When there is a possibility that a substance originated from a living body is mixed, it is required to discriminate it optically and preferably it is adsorbed in a long-wavelength region. When the conjugated system of the cyanine pigment is made long, the pigment is adsorbed by a long wavelength. When a benzene ring in the heterocycle is changed to a naphthalene ring, a wavelength can be made a little longer.

Abstract: PURPOSE:To obtain a new monomer, uniformly and densely supported on the surface of a carrier and capable of producing a DNA probe readily hybridizing the target DNA. CONSTITUTION:The monomer for a DNA probe has a hydrophilic oligonucleotide site containing a saccharide, phosphoric acid and a base and a hydrophobic polymerizable site which is a 6-30C unsaturated fatty acid, an unsaturated alcohol, an unsaturated amine or an unsaturated hydrocarbon or a derivative thereof, e.g. a monomer of the formula. This monomer is obtained by a method for binding a linker such as a beta-amine linker to the 5'-terminal of an oligonucleotide and then binding a hydrophobic site having a group reactive with the linker and polymerizability to the linker, etc.

Abstract: PURPOSE:To enhance acoustic transmission efficiency by continuously changing the acoustic impedance of the acoustic coupler consisting of a hydrogel from the acoustic impedance of a 1st medium to the acoustic impedance of a 2nd medium. CONSTITUTION:The medium 1 is an object having the relatively high acoustic impedance; for example, metallic electrode, etc., and the medium 2 is an object having the relatively low acoustic impedance; for example, liquid or human body, etc. The acoustic impedance Zc of the acoustic coupler 3 changes from Z1 to Z2 along the direction of the medium 2 from the medium 1 in such a case. The hydrogel consisting of a crosslinked molecular and water is used as the gel of this structure. The gel shrinks by generating a phase on according to the concn. of a salt and temp. and continuously changes the acoustic impedance in the gel. The water, etc., are expelled from the inside of the gel to the outside of the gel at this time. The high-polymer concn. and high-polymer density in the gel are thereby increased.
