Inert non-magnetic metals are adhesively bonded to surfaces of metal oxides, for example ferrites, by means of a water vapor-hydrogen atmosphere. Reduction of the metal oxide only takes place at the interface of the inert metal and the metal oxide, after which the metal formed is partly dissolved in the inert metal.

Method of bonding a metal oxide to a metal

A cathode ray tube display device which has an arrangement for mounting a deflection unit on the conical portion of a cathode ray tube envelope. In order to permit a rapid mounting of the deflection unit in a manner which provides shock resistance, and resistance temperature fluctuations in the deflection unit and the envelope, three V-shaped, sheet metal connecting devices connect the deflection unit to the conical portion of the envelope. The free ends of the devices are attached to the deflection unit in such a manner that the vertices of the devices are substantially tangential to the surface of the conical portion. After adjustment of the deflection unit the vertices of the devices are secured to the conical portion in such a manner that the connections are loaded with a shearing force.

Cathode ray tube with improved deflection unit mounting

A method of interconnecting a first element 1 and a second element 4 by means of laser welding, the first element 1 consisting at least partly of glass or ceramics and the second element 4 consisting at least partly of metal, the bond between both elements being formed by the glass or ceramic part of the first element 1 and the metal part of the second element 4, characterized in that a metal auxiliary element 3 is bonded to the glass or ceramic part of the first element 1 by means of a solid-state bond 2, after which, substantially without heating, the metal part of the second element 4 is welded to the metal auxiliary element 3 by means of a laser beam 5.
