Abstract:
A structural unit comprises a frame having a connecting face that surrounds an opening and a cover that is attached to the connecting face to cover the opening. The frame and the cover are formed of materials with different coefficients of thermal expansion, and the connecting face has a channel that opens towards the cover. At least one duct communicates with the channel so that when a filling compound is injected into the duct it is received in the channel. The filling compound thereby attaches the cover to the frame and provides a seal therebetween.
Abstract:
With the present invention, conductor grids for electronic housings and a manufacturing method for such conductor grids are provided. According to the invention, the conductor grid is produced from two metal strips (130, 110, 140) welded along the joint edge (150), with only one of the two metal strips needing to have a surface suitable for the wire bonding. The amount of the conventionally used, plated starting material can be considerably reduced in this way.
Abstract:
A constructional unit has a frame and a cover. The frame and the cover are formed of materials with different coefficients of thermal expansion. A plurality of spacers is arranged between the frame and the cover and defines a gap therebetween. An adhesive is provided in the gap to attach the frame to the cover and simultaneously seal the gap.
Abstract:
Zinc-free nickel alloys for spectacle frames and spectacle parts are described which in addition to very good corrosion properties also show good shaping properties. In addition to nickel, they contain 5 to 20% copper, 2 to 6% aluminum, 0 to 1% beryllium, and up to 0.5% carbon.

Abstract:
Targets for magnetron - sputtering systems with a high utilization of material are obtained from ferromagnetic alloys if the amount of hexagonal structural phase is greater than the cubic phase portion and if the hexagonal prism axis (0001) is aligned preferably vertically to the target surface.
