Abstract: PROBLEM TO BE SOLVED: To provide a liquid test sample storage vessel capable of easily and effectively storing any liquid sample regardless of the kind of liquid test samples and supplying the sample of every storage means with the storage means to a proper observation means or measuring means, and never causing a problem such as liquid leakage. SOLUTION: This liquid sample storage vessel 2 comprises injector tip insert ports 1 at both ends and a flat capillary space continuously provided to the insert ports to store a liquid sample in a thin film form. The insert opening of the injector tip insert port is constituted so as to be tapered from an inlet side having a wide opening capable of inserting an injector tip part 4 to a deep side having a narrow opening on which the inserted injector tip closely abuts. The vessel is formed of a transparent material so as to be observable from the outside. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To enable a colloidal crystal having structure excellent in three- dimensional uniformity to be formed. SOLUTION: Colloidal crystals having structure excellent in three-dimensional uniformity are formed by giving shearing flow to a monodispersive particle solution in which particle density by volume percentage is between 5 and 70% and which is in colloidal crystalline state, and successively making the monodispersive particle solution flow in a uniaxial direction 3 in parallel to a substrate surface in a space held between two smooth substrate surfaces 11a, 11b facing each other in parallel and then making the solution stand still.

Abstract: PROBLEM TO BE SOLVED: To provide a means for producing a colloidal single crystal, by which mixing of air bubbles into a vessel when a colloidal solution is injected can be prevented, the formed colloidal single crystal is prevented from being disordered when a liquid injector is taken out after forming the single crystal and further the formed single crystal can be uniformly dried when the colloidal single crystal is produced by allowing the colloidal solution to flow in a uniaxial direction and imparting shear flow to the colloidal solution in a vessel having a flat plate-shaped capillary. SOLUTION: In the vessel 2 for producing the colloidal single crystal, which has liquid injection ports 1 provided at the both ends of the vessel in a protruding condition and the flat plate-shaped capillary 5 having a gap of ≤0.5 mm, the structure of each liquid injection port 1 is set to have a taper in such a manner that the opening part of the entrance side is wider and the opening part of the back side is narrower. The vessel is made of a transparent plastic having a certain moisture permeability, and a colloidal solution using water as a dispersion medium is used as the colloidal solution.

Abstract: Gelled colloidal crystals obtained by ultraviolet irradiation gelation means proposed so far in the art are inadequate in term of homogeneous gelation as far as their deep portions, and gelled colloidal crystals obtained by use of gelation means relying upon a light source in the visible light range in place of that ultraviolet irradiation has several problems such as difficulty with selection of polymerization initiators and generation of gas bubbles. The object of the invention is to provide a colloidal crystal gelled homogeneously to within, from which those problems are eliminated. To this end, a colloidal solution using an aqueous liquid as a disperse medium with a monomer or macromer added thereto and camphorquinone, riboflavin or their derivative contained therein as a polymerization initiator is irradiated with light having a wavelength component in the range of at least 400 nm to 500 nm for the purpose of gelation, thereby providing a solution to the aforesaid problems.

Abstract: [PROBLEMS] To solve a problem in a conventional colloidal crystal manufacturing means wherein considerable technique is required for obtaining colloidal crystals and its manufacture depends largely on the technique of a manufacturer by establishing a manufacturing means capable of producing the colloidal crystals with excellent reproducibility to apply and expand the use of the colloidal crystals in various fields in the future. [MEANS FOR SOLVING RPOBLEMS] Gas compressed by a compressor (1) is controlled by a gas pulse control device (3) to generate compressed gas pulses, the gas pulses are led into a colloidal crystal manufacturing container (6) with a flat plate-like capillary part through a tube (4), and the motions of flow and its abrupt stop are given to a colloidal solution in the flat plate-like capillary by using as a drive force, a pressure variation given by the pulses. Thus, the colloidal crystals with excellent single crystallinity can be formed.
