Abstract:
An apparatus for determining the amount of any chemical substance exhibiting a surface activity. A monomolecule film including a surface active substance exhibiting a surface activity is formed on a surface of a surface active substance solution in which the surface active substance is dissolved. Subsequently, a surface pressure of the monomolecule film is measured in order to find a concentration of the surface active substance where a content of the surface active substance is defined by the concentration of the surface active substance and the amount of the solution.
Abstract:
A layer element comprises a plurality of monomolecular layers in a regular and alternating arrangement ABABAB . . . on a substrate, wherein A is a layer of a dye whose chromophore has a donor-acceptor structure and B is a layer of cellulose whose hydroxyl groups are at least partly substituted by the radical ##STR1## where R.sup.1 and R.sup.2 are each independently of the other an alkyl radical of from 1 to 4 carbon atoms and R.sup.3 is an alkyl radical of from 1 to 18 carbon atoms or phenyl, tolyl or benzyl. It is useful for nonlinear optics.
Abstract:
Movable barriers as well as auxiliary movable barriers are provided in a trough filled with a liquid forming a monomolecular film thereon. The barriers are driven with a constant positional relationship maintained therebetween to prevent disturbances from occurring in the flow of the monomolecular film. Thus, the monomolecular film is transferred to a substrate with a uniform molecular density. The substrate preferably has a width equal to the length of the movable barriers and the distance between the auxiliary movable barriers.
Abstract:
An ultra-thin, self-assembling molecular film has thickness, length and width dimensions. Ampliphilic molecules in the film are ordered in the thickness dimension, and are arranged in crystals that are aligned in both the length and width dimensions. This molecular alignment in all three film dimensions provides a film having more uniform properties.
Abstract:
An organic film forming apparatus includes a trough storing water therein and a work drive device for moving a work with respect to the trough. The surface of the water is partitioned by a rod into a first developing region on which a monomolecular film is developed and a second developing region on which no monomolecular film is developed. The work is moved by the device through the developed monomolecular film so as to adhere the film on the surface of the work. The device has a holding mechanism which has a holding portion engaged with the work, and which holds the work so that when the work passes through the developed monomolecular film, the holding portion is away from the film or passes through the film after almost the entire work passes through the film.
Abstract:
A film manufacturing method which utilizes a trough storing a liquid therein. The liquid surface of the liquid forms a developing region in which a monomolecular film of organic molecules is developed. The developed monomolecular film is compressed by a barrier to a predetermined surface pressure. A workpiece having a build-up surface is moved by a vertical moving mechanism in a direction perpendicular to the developing region through the monomolecular film while being moved ahead of the build-up surface in a horizontal direction by a horizontal moving mechanism, so that the monomolecular film is built up on the build-up surface.
Abstract:
An apparatus is provided for forming a monomolecular film or a monomolecular layer built-up film on a substrate by spreading a group of monomolecular film-forming molecules on a liquid surface and contacting the substrate with the group of the monomolecular film-forming molecules. The apparatus comprises a frame for confining the spread liquid surface and structure for isolating and moving at least two different monomolecular layers on the spread liquid surface within the frame.
Abstract:
Disclosed is a method and apparatus for continuously forming and depositing a layer of monomolecular amphiphilic molecules on a substrate. The present invention includes an apparatus and method for transferring and compressing an uncompressed molecular layer from one liquid surface region to another adjacent liquid surface region by using non-moving or static mechanical components which do not come into direct contact with the monomolecular layer. The present invention is based on the fact that by continuously flowing liquid from one region to an adjacent region by using non-moving or static mechanical components that do not touch the monomolecular layer, a monomolecular layer having surprisingly little damage can be transported to the adjacent region and simultaneouly compressed by the flowing liquid surface. The monomolecular layer can then be coated onto a substrate. Due to the present invention, it is now commercially feasible to continuously supply one region with a solution of amphiphilic molecules, and then to deposit continuously onto a substrate or onto several substrates within a region in flow communication with the former region, the monomolecular layer which has been compressed and transported into this latter region.
