An electro-optical device comprises a stack ( ) of layers on a substrate ( ), which stack of layers includes an organic luminescent layer ( ) sandwiched between electrode layers ( ). A hollow cover ( ) is provided over the stack ( ) and connected to the substrate ( ) in a gastight manner. A water getter ( ) is accommodated in the cover ( ) so as to abut against a wall ( ), which extends along the stack ( ). The wall ( ) has an indentation ( ) accommodating control electronics ( ) used to operate the device. The control electronics ( ) may be connected to the device by way of a flexible toil ( ) having conductor tracks ( ), and fixed in the indentation ( ) by way of an adhesive ( ).

Electro-optical device with cover having a first wall indentation for accommodating control electronics

An EL device according to the invention comprises a seal of an organic sealing material which substantially does not extend inside the inner perimeter 8 of the sealing surface. To be able to provide the sealing material between the sealing surfaces by capillary action, the seal has a thickness of less than 100 micrometers. Preferably, the seal has a thickness of less than 10 micrometers and a width of more than 0.2 mm, so that the diffusion of volatile materials through the seal is greatly reduced.

Organic electroluminescent device

An electron tube comprising a stack of at least one perforate plate-shaped insulating element and at least one perforate plate-shaped metal electrode structure, the insulating element comprising a core and being provided with an aluminium layer at least on a side facing the electrode structure, at least the outer layer of the aluminium layer being oxidized, and the coefficients of thermal expansion of the core and the electrode structure being at least substantially equal. In this manner, the thermal stresses occurring between the insulating element and the electrode structure during firing are reduced, so that the risk of their displacement relative to each other is reduced.

Electron tube having electrode and insulator components with matched

A device for rendering cables such as electric cables, telecommunication cables, optical cables, longitudinally watertight by the block-wise application of a sealing compound into the cable core by means of an intermittently displaceable nozzle which is periodically displaced by a driving element, the speed of the driving element being synchronized with the linear speed of the cable core.
