A film in which the hydrophilic end of an amphipathic substance such as soap, stearic acid, or araxic acid is attached to the surface of a substrate such as quartz, and the above amphipathic substances are juxtaposed upright on the surface of the substrate such as quartz. means. To manufacture this, as shown in FIG. 3, a substrate 2 such as quartz is dipped through the surface of water 1, an amphipathic substance 3 is suspended on the water surface, and a fence 4 is immersed. The substrate 2, such as quartz, is gently pulled up while reducing the area of the water surface on which the amphiphilic substance 3 floats, and the amphiphilic substance 3 is placed upright on the substrate 2, such as quartz, as shown in FIG.・It is a juxtaposition.

なっていた。そのため、よりすくれたＬＢ膜累積装置の
開発が望まれていた。In the method for manufacturing an LB film according to the prior art mentioned above,
Since the fence 4 was compressed only in one direction as shown by the arrow, the amphiphilic substance 3 wrapped around the back of the substrate 2 such as quartz, and this wrapping caused the disorder of the film of the amphiphilic substance 3. Also, when the fence 4 is compressed, the film of the amphipathic substance 3 rubs against the side of the aquarium, causing the amphiphilic substance 3 to
This disturbance in the film of the amphiphilic substance 3 prevents the amphiphilic substance 3 from uniformly adhering to the substrate 2, such as quartz, and prevents the formation of a high-quality LB film. This was a hindering factor. Therefore, it has been desired to develop a more compact LB film accumulation device.

板２の面に付着してＬＢ膜が製造される。In the top view of FIG. 1a, reference numeral 5 is a water tank in which water 1 is placed.
The amphiphilic substance 3 is attached to the center of the L
A substrate 2 of quartz or the like that will become the B film is partially immersed. Reference numeral 6 denotes a centripetal aperture reduction mechanism, which has the same mechanism as a mechanical shutter of a camera. When the drive mechanism 62 is operated, the aperture of the centripetal aperture reduction mechanism 6 is reduced, and the water surface within the aperture is reduced. When the amphiphilic substance 3 floating on the substrate 2 is compressed and the substrate 2 made of quartz or the like is pulled up, the amphiphilic substance 3 adheres to the surface of the substrate 2 made of quartz or the like to produce an LB film.

縮少する。Referring to FIG. 2, reference numeral 61 denotes a triangular flat unit body, and a rectangular slit 65 is provided along a base 64 opposite to an acute vertex 63. As shown in the figure, a plurality of triangular flat unit bodies 61 are arranged in an inclined fan shape so that their acute apexes 63 are generally centered. When arranged in this way, the direction of the slit 65 is somewhat inclined from the circumference 67 (indicated by the - dotted chain line) of the aggregate of triangular flat unit bodies 61 arranged in a fan shape. If the drive mechanism 62 or the like is inserted and moved along the circumference 67, the opening surrounded by the collection of triangular flat unit bodies is reduced isotropically and centripetally.

引き上げる基板回転引き上げ機構である。In the first example, the substrate 2 made of quartz or the like was pulled up in a non-rotational manner, but the water surface within the centripetal aperture reduction mechanism 6 rotated somewhat. Since this may cause disturbance to the amphiphilic substance 'w3 floating on the water surface, in order to prevent this, the substrate 2, such as quartz, is synchronized with the drive mechanism 62 of the centripetal aperture reduction mechanism 6. It rotates. In the figure, 61 is a triangular flat unit, 62 is a drive mechanism, and 7 is a substrate rotation and lifting mechanism that pulls up the substrate 2 of quartz or the like while being rotated by the drive mechanism 62.

When the substrate 2 made of quartz or the like is cylindrical or prismatic, almost no disturbance occurs in the amphiphilic substance 3 floating on the water surface, and a very remarkable effect is observed.

Ｂ膜が製造される。As explained above, in the LB film accumulation device according to the present invention, the amphiphilic substance 3 floating on the water surface around the substrate 2 such as quartz on which the LB film is formed is isotropic and centripetal. Since the amphiphilic substance 3 is compressed to a uniform temperature, no disturbance occurs in the amphiphilic substance 3, and when the substrate 2 such as quartz is pulled up, the amphiphilic substance 3 uniformly adheres to the surface of the substrate 2 such as quartz, and is of good quality.
