  • Publication number: 20080160455
    Abstract: An exposure pattern having a line width of submicron size is simply formed by using an inexpensive and stable solid state laser or a gas laser as an exposure light source, and by using a photoresist for g-line or i-line. The exposure is performed by locally controlling a reaction time constant of the photosensitive material with beaming the laser beam on a predetermined portion of a layer of the photosensitive material having a predetermined thickness formed on the surface of a substrate W, with beam intensity and scanning rate of the laser beam being controlled.

  • Patent number: 6787295
    Abstract: There is disclosed a method of preparing a photographic solid fine-grain dispersion, the method comprising the steps of: successively bringing a slurry of a water-insoluble photographically useful compound in a grinding chamber of a dispersing machine, which chamber is filled with media, allowing the compound to contact the media in the grinding chamber, to produce fine grains of the compound successively, successively separating the media from the compound by centrifugal force, and taking the compound out of the grinding chamber, using specific media with given physical properties. There is also disclosed a dispersion obtained by the method. According to the method, the photographic solid fine-grain dispersion is prepared efficiently, without coarse grains or abrasion materials resulting from media or so, and the dispersion causes no defect when coated in a form of a coating film.

  • Publication number: 20030170423
    Abstract: The present invention provides a method of producing a pattern member at high productivity and low cost. In the method of the present invention, inks of plural colors are applied on a substrate and dried to produce several kinds of single color films having color ink layers of plural colors formed on the surface, then, the single color film of R color is overlapped on the substrate, and the overlapped substrate and single color film are pressed by a pressing member having a convex portion of given pattern formed on the surface, to transfer parts corresponding to the pattern of the convex portion of the color ink layer to the substrate. The above-described operation is repeated at frequency corresponding to plural colors to form a multi-color pattern composed of color ink layers of plural colors of given pattern on the substrate.

  • Patent number: 5795506
    Abstract: In a production line for microcapsules, which is provided with an emulsifying machine, an emulsion or microcapsules are automatically sampled on a on-line basis from a portion of a process pipeline, which portion is located downstream of the emulsifying machine. The obtained sample is fed into a particle diameter measuring device, and the particle diameters of the microcapsules in the sample are automatically measured by the particle diameter measuring device. A calculation is made by a process computer in order to find the difference between the measured values of the particle diameters and a desired particle diameter. The value of a rotation speed of the emulsifying machine, which value yields the desired particle diameter, is calculated in accordance with the relationship between the rotation speed of the emulsifying machine and the mean particle diameter, the relationship having been inputted previously.

  • Patent number: 5405558
    Abstract: A method for manufacturing microcapsules which prevents capsule particles from adhering to the inner wall surfaces of a wall-film-forming reactor device, thereby to eliminate the possibility that qualities of the microcapsule, such as the heat resisting, solvent resisting and other properties thereof, are deteriorated, and to eliminate the need for an operation to clean substances adhered to the inner wall surfaces of the wall-film-forming reactor device, and therefore, which is able to manufacture microcapsules at a high production efficiency. An emulsified solution is injected into a wall-film-forming reactor device from the lower portion thereof by an emulsified solution feed pump. After completion of a given time of a wall-film-forming reaction in the wall-film-forming reactor device, the emulsified solution is discharged from an overflow outlet formed in the upper portion of the device, and is then cooled by a heat exchanger.
