Conventionally, various methods have been used to form thin films of organic compounds on substrates such as glass, metal materials, metal vapor deposited films, etc. One of these methods is a method of forming a monomolecular layer of amphipathic molecules, such as Langmiu. Arbrodiet, “Physical Review” (Langmuir-
Blodgett, ``Physical Review'') 51 , 664 (1937)
proposed by. In this method, a solution of a saturated fatty acid, which is an amphiphilic molecule, dissolved in a volatile solvent such as benzene is gently dropped onto the water surface, and a monomolecular layer is left behind after the solvent evaporates. After compressing the monomolecular layer thus formed to a predetermined surface pressure, the glass substrate is immersed in water and pulled up to form a solid monomolecular film on the glass surface. In this case, when the glass substrate is pulled up, the hydrophilic groups facing water in the monomolecular film are attached to the substrate side, and the hydrophobic groups (or lipophilic groups) are lined up on the surface, forming a monomolecular film structure, as shown in Figure 3. (referred to as A-type membrane). Further, when a glass substrate is immersed, a monomolecular film structure is formed in which the hydrophobic groups (or lipophilic groups) are attached to the substrate side and the hydrophilic groups are arranged on the surface as shown in FIG. 4 (referred to as a B-type film). (``Thin Film Handbook'', pp. 268-269, edited by Japan Society for the Promotion of Science, December 1981, published by Ohmsha Co., Ltd.).

（例えば、特開昭52−98038号公報）。 Solid monomolecular films produced by such a method have recently come to be used as insulating layers in fields such as electronics, and various improvements have been proposed (for example, Japanese Patent Laid-Open No. 52-98038).

It was proposed to provide it as a layer (Special Publication No. 56-30609).

る。 In these improved methods, for example, as shown in Figure 2, saturated fatty acids such as stearic acid and palmitic acid are added to the surface of the lower liquid (aqueous layer) 2 in a tank 1 in a volatile solvent such as benzene and chloroform. The solution is dropped to form a monomolecular layer 4 of saturated fatty acid on the water surface, and the monomolecular layer 4 is compressed into a solid state using an appropriate compression means such as a cylinder 5 partially immersed below the water surface. A monomolecular film (coagulated film) 6 is formed, and a protective layer 9 of a monomolecular film is formed on the surface of a substrate 8 guided by a guide roller 7 provided in water. In this case, as shown in FIGS. 3 and 4, if a monomolecular film is formed when the substrate is pulled up, a B-type film is formed when the A-type film is pulled in. The monomolecular layer that adheres to the substrate and spills out is transferred to the nozzle 3.

装置が開示されている。 In the methods disclosed so far, the apparatus for forming a solid monolayer by compressing a monomolecular layer of amphiphilic molecules formed on a lower liquid (aqueous phase) is, for example, the above-mentioned Japanese Patent Publication No. 56 In the method exemplified in Japanese Patent Publication No. 30609, surface pressure is applied to the monomolecular layer on the liquid surface by pressing a barrier existing on the liquid surface with a spring.
The publication describes that by rotating a horizontally installed cylinder with part above the liquid surface and part below the liquid surface, a monomolecular layer formed on the liquid surface is placed on the cylinder above the liquid surface. An apparatus is disclosed in which the monomolecular film is conveyed to a coating area, thereby applying surface pressure to the monomolecular film to form a solid monomolecular film.

However, in all of these devices, the pressure member is above the liquid surface, so extreme care must be taken to avoid causing ripples on the liquid surface and disturbing the monomolecular layer or solid monolayer. things that should not happen,
Since there are many opportunities for the pressure member to come into contact with the monomolecular film,
In some cases, the attachment and detachment of amphipathic molecules becomes uneven,
Smooth transfer of the monomolecular layer to the coating area may be hindered, and therefore consideration must be given to the selection of the material of the pressure member and its operation and maintenance. SUMMARY OF THE INVENTION An object of the present invention is to provide a solid monomolecular film forming apparatus that eliminates the above-mentioned drawbacks and provides stable conditions for operation and maintenance.

得ることが出来る。 Next, the liquid uniform blowing means means that a monomolecular layer is formed, and a compressive pressure is applied to the monomolecular layer by the flow of liquid to form a solid monomolecular film.
It is important that the liquid in the liquid tank moves uniformly in the width direction of the web substrate. Therefore, in order to uniformly blow out the liquid supplied from the liquid transport means in the width direction, it is desirable to once change the dynamic pressure of the liquid sent by the transport means to a uniform static pressure and blow out using this static pressure. For this purpose, a chamber extending across the width of the liquid tank with a large number of pores in its outer wall, a net-like chamber, or a chamber covered with dense cloth or the like is used. This uniform blowing means allows the liquid to move uniformly in the width direction of the liquid tank.

For this purpose, it is a means for appropriately adjusting the flow path in order to provide the necessary liquid velocity and direction of liquid flow, and a weir-like type, a guide-type type, etc. are used.

In the present invention, in the configuration as described above, the liquid transport means flows the liquid in the direction of forming the liquid layer from a monomolecular layer to a collective monolayer in order to apply a compressive force to the monomolecular layer. The liquid uniform blowing means forms a uniform liquid flow across the width of the liquid tank, and the liquid speed adjusting means controls the flow of the liquid layer in the process of forming a solid half-molecular film from a monomolecular layer. Its role is to provide the appropriate liquid velocity for the location. As described above, the present invention can provide liquid flow with uniform liquid velocity and direction in the width direction without creating waves on the liquid surface, thereby compressing the monomolecular layer and making it possible to form a solid monolayer. It is possible to form a molecular film.

体）８の上に塗布し保護層９を形成する。 In the lower liquid tank 1, a pump 10 provided outside the tank
As an example of the liquid blowing means, a chamber 14 surrounded by a perforated plate 12 was used at the bottom of the tank. The liquid is blown out from this chamber 14 into the tank through the perforated plate 12 in a uniform distribution. In this case, in the liquid surface region where the monomolecular layer 4 is formed, there is almost no movement of the liquid surface. The solvent in the monomolecular layer 4 is evaporated by heating means 12 . The flow path of the lower layer liquid is narrowed by the guide plate 11 serving as a liquid speed adjusting means, so that the flow speed near the liquid surface gradually increases, and reaches the maximum speed at the point where the liquid surface and the guide plate are closest. , the liquid surface is compressed toward the coating device, whereby the monomolecular layer 4 forms a solid monomolecular film 6.
Then, the liquid is sucked into the pump again from the liquid suction port at the bottom of the lower liquid tank, and the liquid continues to flow. On the other hand, the produced solid monomolecular film 6 is coated onto a web-shaped substrate (magnetic recording medium) 8 using a coating device 15 to form a protective layer 9.

Since the present invention uses liquid flow to apply compressive force to the monomolecular layer existing on the lower liquid surface, there is no need for special considerations in selecting materials, operation, and maintenance using a pressurizing member, and it is possible to maintain stable conditions. It became possible to manufacture it. In addition, in the present invention, liquid filtration and adjustment of components, temperature, etc. can be easily performed by liquid circulation, so the device is advantageous for changing the conditions for forming a molecular layer and a solid monomolecular film.
