摘要： PROBLEM TO BE SOLVED: To solve the problem that the flatness of the glass surface of a micro chemical chip, obtained by integrally laminating a plurality of glass sheets and joining the sheets by thermal fusion of glass, is insufficient because of the warpage of the glass sheet.
SOLUTION: In the method for producing a joined member, glass members each containing silicon dioxide as a main component are joined to each other, and a solution of a silicon alkoxide compound is used for bonding the joining faces. At the time of joining, heating or an external force is applied onto the joining face to press it in order to increase bonding strength. It is possible to obtain the micro chemical chip having a fine flow passages by integrally laminating a glass sheet having grooves and a glass sheet by the method.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a polarizer in which an effective region can be formed over the whole of the surface of a substrate, and, the desired number of polarizers can be inexpensively obtained with dimensions corresponding to a request and at an angle to the direction of ruggedness compared with the conventional production method for photonic crystals. SOLUTION: The method for producing a polarizer comprises: a process where a prescribed sol liquid is applied over the whole of the surface of the first base material composed of a translucent inorganic material, so as to form a prescribed coating film; a process where, in a state where a master mold is pressed against the coating film of the first base material, heating-holding is performed, and the coating film is cured, so as to form a surface to which periodical rugged shape in a specified direction is imparted on the coating film; and a process where many units of double layer films where one unit is composed of the first layer of a high refractive index translucent material and the second layer of a low refractive index translucent material are stacked, so as to form a multilayer structure, and a polarizer original plate with a large area of ≥400 mm 2 where the whole face is made into an effective region is obtained, so as to provide a hybrid polarizer.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a glass substrate with grooves the bottom face of which has nearly flat shape by a wet etching process. SOLUTION: This method for manufacturing the glass substrate with grooves comprises fusion-bonding a first glass sheet and a second glass sheet, and forming the grooves by the wet etching process using hydrofluoric acid, where solubility to the acid of the second glass sheet at the bonding face with the first glass sheet and its vicinity is made less than that of the first glass sheet, and the grooves are formed by etching with hydrofluoric acid from the surface of the first glass sheet through the bonding face with the second glass sheet. Compositions of the first glass sheet and the second glass sheet may be made different from each other. Alternatively, a compressive stress layer (a layer having a specific volume smaller than that inside) may be formed at the glass surface being the bonding face of the second glass sheet and its vicinity while the compositions of the first glass sheet and the second glass sheet are made the same.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a micro-chemical chip, obtained by heating and fusing using a press contact method carried out by laminating 2 sheets of glass plates and pressing the contact face from the outside, scatters a part of an incident light to cause inconvenience for an analysis using an optical system such as a photothermal conversion spectrometory because the surface unevenenss of a ceramic-made pressing plate for pressing the contact face is transferred to the glass plate to remain as a press mark. SOLUTION: In this method of manufacturing the micro-chemical chip provided with a fine flow passage on the contact face by fusing and joining 2 glass plates at least one of which has a groove formed on the surface, a closed space of the fine flow passage formed by the lamination of the 2 glass plates is evacuated to reduce the pressure to bring the glass plates into close contact with each other. The glass plates are heated to near a glass transition point in this state to fuse and join the glass in the contact face. The space is preferably evacuated to reduce the pressure to ≤1 Pa.
