The projection-type cathode ray tube includes a phosphor screen panel, a phosphor screen formed on an inner surface of the phosphor screen panel, a face panel which is arranged to face the phosphor screen in an opposed manner, and an electron gun for forming an image on the phosphor screen, wherein the phosphor screen is inclined with respect to a tube axis on which the electron gun is arranged.

Abstract: A pair of magnets of which magnetizing direction differs from each other in the horizontal direction (X axis) are arranged at upper and lower portions of a funnel-side opening portion of a deflection yoke. The pair of magnets are held and fixed to a coil support body which supports horizontal deflection coils in a state where the magnets are embedded in the coil support body. In a projection type cathode ray tube of a single electron beam method, a locus of an electric beam which receives the deflection distortion is corrected so as to correct an electron beam shape on a screen to an approximately circular shape whereby a focusing performance of a display image on a screen is enhanced.

Abstract: A technology is disclosed to enable VP/VC on an ATM network to be backed up by using an ISDN line without presetting any detailed information regarding a backup VP/VC to be set on the ISDN line. An ATM switch A30 is provided to establish the ISDN line connecting with an ATM multiplexer A20 when any failure occurs in an ATM transmission path contacting with the ATM multiplexer A20. Negotiation is carried out with ATM multiplexer A30 by using the established ISDN line so as to decide a channel characteristic of a backup VP/VC to be set on the ISDN line. Then, the ATM switch A30 and the ATM multiplexer A20 communicate with each other by using the backup VP/VC having the decided channel characteristic on the ISDN line.
