  • Publication number: 20150114291
    Abstract: The present invention is to provide a technology for forming an organic compound film having a uniform thickness on a film at a high film formation speed while transporting the film in a vacuum chamber. In a vacuum chamber, a film reeled out from a mother roll is transported in contact with a center roller and an organic compound film is formed on the film. A vapor emission device disposed in a film deposition chamber provided in the vacuum chamber and having a vapor emission unit which emits and blows a vapor of an organic compound monomer to a film on the center roller, and an energy ray-emitting device for irradiating an organic compound monomer layer formed on the center roller with an energy ray so as to cure the organic compound layer are provided.

  • Publication number: 20150114290
    Abstract: The present invention forms an organic thin film at a high film formation rate by vapor of an organic compound generated by heating. A film formation chamber is disposed in the interior of a buffer chamber; a part of the side surface of a center roller is inserted in the film formation chamber from a film formation chamber opening; and a base material film is run in close contact with the side surface in the part. The vapor is carried by a carrier gas from a vapor generation device connected to the film formation chamber; the center roller is cooled by a cooling device; the base material film is cooled to temperatures lower than the condensation temperature of the vapor; and an organic raw material layer is formed on the surface of the base material film by the vapor discharged into the film formation chamber, which is cured by the irradiation with an energy ray in the curing chamber while rotating the center roller.

  • Patent number: 5881378
    Abstract: A derived database processing system in a database processing device comprises a plurality of independent databases which can provide a plurality of users with a group of data to be shared for a common purpose. The derived database processing system comprises a dictionary for managing database logical definition information and database storage information in a secondary memory, a derived database registering unit for determining a definition frame of a new name without violating a definition frame of a name used in a schema definition which defines data in a database, a dictionary information manipulating means for referring to said dictionary when the manipulation target is a derived database, then selecting necessary components of said database, and a database processing procedure generating unit, in a binding process to optimize access routing in a database.

  • Patent number: 5857195
    Abstract: A method of developing a self-describing database management system comprises the steps of holding definition data of a database management system to be developed as data on a database and creating a database management system to be developed by the use of an existing database management system. The database management system to be developed comprises a data definition processing execution program and a bind processing execution program. These two programs include a process to permit access to definition data which form database, and are executed based on the definition data on the database.

  • Patent number: 5742809
    Abstract: A database generic composite structure processing system stores data expressed by a logical structure and generates an access schedule in response to an query. The system comprises a generic composite structure element for storing definition information for associating a partial data comprising a table or a partial table expressed by a logical structure with a composite structure of a database in an independent structure in physical media, and for storing definition information for storing data and an optimizing process element for generating, according to the generic composite structure defined by said generic composite structure means, an executable module which is a concrete result of an access schedule in response to an query.

  • Patent number: 5553303
    Abstract: A database processing system using a multi-processor including a plurality of processor modules each having a local memory connected to an external shared memory. The database processing system includes a composite structure definition control part for defining an administrative processor module for controlling an access to a composite structure of a database which has a storage structure independent of a logical structure; and a maintenance/selection control part in an optimum control processor for providing a function of access-controlling a shared process and a local process when an access request arises for a database composite structure, and for dynamically switching the access control process for the composite structure according to the access frequency notified by each processor module.
