Abstract: The present invention provides a method and apparatus to browse the Web without using a web browser. The application server in a transmitting unit converts a web page transmitted from the Internet into video data and provides links to the video data on the basis of the links provided to the web page. In the video server of the transmitting unit, the video data transmitted from the server is compressed by the MPEG2 encoders, and sent with information about the links provided to the video data. A ‘Set-Top Box’, of the receiving terminal outputs the received video data to a display, and establishes an association between the links provided to the video data and a position of a cursor displayed on the screen of the display.

Abstract: To provide a technique for dynamically selecting an optimum communication route based on estimated transmission speed over different communication lines, a network system comprises the processes of measuring data transfer rates of a telephone line for transmitting data between a server and a client bidirectionally and of a satellite line for transmitting data in only one direction from the server to the client; and selecting one from the telephone line and the satellite line on the basis of the measured data transfer rates.

Abstract: A technique is provided for automatically and visually generating a display rule for a structured document based on an exemplary operation. Base display rule generation means 21 generates a first display rule 29, which is a base, by using a document type definition 27 for a structured document 26 and a default generation rule 28 that is determined in advance. Display document generation means 22 employs the first display rule 29 and the structured document 26 to generate a first display document 30 and an element correlation file 31. Tie first display document 30 is edited in a display document visual editing environment 23, and a second display document 32 and an editing operation history file 33 are generated. Display rule updating means 24 refers to the second display document 32, the editing operation history file 33, the element correlation file 31 and the structured document 26 to generate a second display rule 34 that reflects the editing contents.

Abstract: A working fluid comprising 1,1-difluoroethane (HFC-152a) of formula (1), 1,1,1,2-tetrafluoroethane (HFC-134a) of formula (2), and carbon dioxide. This can provide a new working fluid which not only functions satisfactorily as a working fluid, but also exerts little influence on ozone layer depletion and global warming.

Abstract: A nondestructive inspection method of inspecting a securing defect of a polymer insulator having an FRP core, an outer cover portion arranged around the FRP core, and at least one metal member secured to at least one end of the FRP core, includes the steps of; measuring an acoustic emission signal generated when the metal member is secured to the FRP core by using compression dies; and determining whether or not the securing defect is generated on the basis of the acoustic emission signal in process. Moreover, the disclosed apparatus performs the nondestructive inspection method mentioned above.
