  • Patent number: 10071565
    Abstract: A heating element is provided with a conductive path pattern which can be printed in a mask-free manner (e.g., drop-on-demand) with existing printing technology. The printing step can be performed, for example, with a thermal inkjet printer, a piezoelectric inkjet printer, an aerosol jet printer, or an ultrasound printer. The ink solution can be formulated so that it establishes an electrically conductive path which is free of polymer binders.

    Abstract: Getter materials are described. The getter materials have non-evaporable getter alloys in their powder form having high gas sorption efficiency, particularly for hydrogen, carbon oxide and nitrogen, which after having lost their functionality in consequence of the exposure to reactive gases at a first temperature, can then be reactivated through a thermal treatment at a temperature between 400° C. and 600° C. The alloy powders have as compositional elements titanium and silicon and at least one additional metallic element selected among vanadium, iron and aluminum and have an atomic percentage composition of the elements which can vary within the following ranges: 1. Titanium from 60 to 85 atomic percentage; 2. Silicon from 1 to 20 atomic percentage; and 3. The sum of vanadium, iron and aluminum from 10 to 30 atomic percentage.

  • Publication number: 20020145128
    Abstract: Moisture absorbent is embedded in a sheet-type support by a centrifugal force. A gas permeable sheet is fixed to one face of the support via an adhesive layer and a protection sheet is fixed to the other face of the sheet-type support via an adhesive layer. In this way, a moisture absorbent sheet is previously prepared. When in an organic EL display, the protection sheet is removed from the moisture absorbent sheet, the adhesive layer comes into contact with an opposed face of a seal cap and the moisture absorbent sheet is fixed to the opposed face. The seal cap is put on a transparent insulating substrate in which an anode layer, organic EL lamination body, and a cathode layer are laminated. The seal cap comes into contact with the transparent insulating substrate via seal resin of ultraviolet-curable type and ultraviolet rays are irradiated so as to complete the organic EL display.
