Abstract: A method for producing a polytetrafluoroethylene particle, which includes subjecting tetrafluoroethylene to suspension polymerization in an aqueous medium to prepare a suspension-polymerized particle of polytetrafluoroethylene, washing and then crushing the suspension-polymerized particle or crushing the suspension-polymerized particle with washing to prepare a crushed particle, dehydrating the crushed particle to prepare a crushed particle having a water content of 40% by mass or less, and subjecting the dehydrated crushed particle to heat treatment to produce a polytetrafluoroethylene particle.

Abstract: A method for producing a polytetrafluoroethylene powder, which includes subjecting tetrafluoroethylene to suspension polymerization in an aqueous medium to prepare a suspension-polymerized particle of non melt-processible polytetrafluoroethylene, drying the suspension-polymerized particle to prepare a dry particle, subjecting the dry particle to fluorine radical treatment to prepare a fluorine radical-treated particle, and crushing the fluorine radical-treated particle to produce a polytetrafluoroethylene powder. Also disclosed is a polytetrafluoroethylene formed article obtained by forming the polytetrafluoroethylene powder, as well as a polytetrafluoroethylene compression-molded article obtained by compression molding the polytetrafluoroethylene powder.

Abstract: The present invention provides a system and a method for speeding up immigration. In first immigration, first biometric information is stored in a immigration biometric information DB. A normal immigration client terminal displays a first result of comparing an ID information watch list with a biometric information watch list. In subsequent second immigration, the first biometric information in the immigration biometric information DB is compared with second biometric information obtained by a simplified immigration client terminal. Then, the simplified immigration client terminal displays a second result of comparing the first biometric information with the watch list information that is added after the first comparison is done. Thus even if the number of registrations in a watch list database is large, a small amount of similar watch list information is displayed, reducing the time for checking the results by the operator.

Abstract: A print managing apparatus is provided, which is able to reduce the possibility of information leakage due to the printed material, without implementing a new function in the network printer. When there is a directive to perform printing, the print managing apparatus generates a release key, incorporates the generated release key in the print data, and transfers the print data to the network printer. Then, the print managing apparatus displays on the display device, a screen prompting for a release key that corresponds to the release key, which is printed on a printed medium together with the print data.

Abstract: A print management system is provided with a printer having a tag reader that reads a unique identifier of an IC tag attached to a medium, a log server that acquires information related to printing on the medium as a log, an ID management server that receives the identifier read by the tag reader, links the identifier to the time of printing on the medium or time at which the information of the IC tag is received and holds them in a storage and a print log integrating server that transmits the identifier of the IC tag attached to the medium to the ID management server, acquires the time at which the identifier is received from the ID management server, acquires logs in the vicinity of the time from the log server, links the log and the medium, stores and manages them in the storage.

Abstract: A copy machine control apparatus that can realize copy management of a print, editing a duplicate, management of distribution destinations of a duplicate, and control of outward transmission of a duplicate, by the use of a conventional digital copy machine. The copy machine control apparatus acquires a scan image of a print from a digital copy machine, processes the acquired scan image, and thereafter returns the processed scan image to the digital copy machine to print the processed scan image on a substrate.
