摘要： PURPOSE:To reduce the film thickness of a display layer and to increase a contrast even if a driving voltage drops by inclining the display element for which a high polymer dispersion type liquid crystal is used with the normal of the optical axis of its incident light. CONSTITUTION:The display element for which the high polymer dispersion type liquid crystal is used is constituted by installing the display element at 30 to 70 deg. swing and tilt angle with the normal of the optical axis of the incident light used for making display. Glass, plastic, etc., are used for substrates 101, 101' of such display element. Electrodes 102, 102' are formed thereon and further, a display layer 103 is formed thereon. The formation of the display layer 103 is executed by laminating a porous polymer matrix 104 via an adhesive layer or directly, then dispersing low-polymer liquid crystals 105 therein. The incident light 110 is made incident on the display layer 103 at a certain angle with the electric field to be impressed thereto. This angle is nearly equal to the swing and tilt angle 111 formed by the normal 109 of the display element and the incident light 110 and is used at 30 to 70 deg..

摘要： PURPOSE:To provide a organism minor-component examination device, having a small-sized and simple structure, and generating little examination waste liquid. CONSTITUTION:A reaction vessel 30, a flow cell 31, and a waste liquid vessel 32 under a reduced pressure state are united mutually, and the flow cell 31 is formed of optically transparent material. Absorption members 33 are included in the connection portion of the flow cell 31 and the waste liquid vessel 32, and in the waste vessel 32. A reagent, a specimen, and the like are injected in the teaction vessel 30 through an inlet 34, and are stirred by means of a stirrer 35 so as to accelerate a complex formation reaction. After the progress of the reaction in reaction liquid, the reaction liquid is diluted by dilution liquid. Then, the reaction liquid flows out of the reaction vessel 30 via the flow cell 31 owing to the capillary phenomenon of the waste liquid vessel 32, and measurement is performed at the flow cell 31 using laser radiation L.

摘要： PURPOSE:To separate coagulation of carrier particles to highly accurately measure immunological activation. CONSTITUTION:A wedge-shaped transparent cover member 2 with a recess 2a provided at the center on an inner side is tightly attached on a flat substrate 1 formed of a. transparent member wherein a slit is formed by the recess 2a. Height of the slit between the recess 2a and the substrate 1 is designed to be reduced uniformly. Carrier particles F are sensitized with an immunological active substance, and when a reagent wherein the carrier particles F are dispersed in a liquid medium mainly comprising water is mixed with a sample, reaction occurs so that a plurality of immunological active substances and the carrier particles F form coagulated bodies G. If the reactant solution L is injected into the slit between the substrate 1 and the recess 2a, the reactant solution L enters toward a B direction where a vertical distance is narrow due to surface tension. Since non-coagulated carrier particles F are smaller in diameter, they can move into depth, while the coagulated bodies G are trapped in the midway and suspended depending on their size.

摘要： PURPOSE:To eliminate irregularity on a surface of a pattern and improve durability by manufacturing an insulating pattern electrochemically when printing is to be performed by using an ink whose adhesive property changes by application of voltage. CONSTITUTION:An insulating mask 3 is formed on a surface of a conductive material 4 consisting of an insulating material such as high polymer filled with a conductive donor material such as carbon black, which is electrolyzed as an anode in an electrolytic solution 2. As a result, the conductive donor material in a conductive part 8 is eliminated electrochemically so as to make the conductive part 8 to be an insulating part. Then, the mask 3 is removed so as to make an insulating pattern on the surface of the conductive material 4.

摘要： PURPOSE:To improve contrast and dispense with a polarizer and/or an analyzer at the time of regeneration by forming a recording layer into two-layer structure, and disposing the optical anisotropic directions of the adjacent recording layers to be orthogonal to each other. CONSTITUTION:A recording layer 4 is clamped between a base 1 provided with an orientation membrane 3 and an electrode 2, and a base 1' provided with an orientation membrane 3'. A recording layer 4' is clamped between the base 1 provided with an orientation membrane 3''' and the electrode 2, and the base 1' provided with an orientation membrane 3''. This recording medium is thus formed into the structure provided with two recording layers. The oriented direction of the orientation membrane 3 is disposed to be orthogonal to that of the adjacent orientation membrane 3', and the orientations directions of the orientation membranes 3' to 3'' and 3'' to 3''' are disposed to be respectively orthogonal. The optical anisotropy directions of the adjoining recording layers 4, 4' are thus disposed to be orthogonal. Contrast can be thereby improved, and a polarizer and/or an analyzer at the time of regeneration can be dispensed with.
