Hendrikus J. J. M. Van Haren has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6125027
    Abstract: A component includes a substrate layer (1) of glass or Al.sub.2 O.sub.3, an anti-reaction layer (2) or a levelling layer (2), two electrode layers (3, 5) and a dielectric layer (4) as well as such a capacitor. Manufacture a component which provides for cost-effective, surface-mountable (SMD). The anti-reaction layer (2) on the glass substrate (1) or the levelling layer (2) on the Al.sub.2 O.sub.3 -substrate (1) is made of at least one specific material. An anti-reaction layer or a levelling layer (2) of one of the above-mentioned substances or a combination of several substances, enables a dielectric layer (4) to be provided by means of which a high capacitance value is achieved.

  • Patent number: 4956744
    Abstract: In a multilayer capacitor, which is made of alternate layers of a dielectric oxidic ceramic material and an electrode material, and which is provided with metallic end contacts which electrically conductively contact a prescribed part of the layers of electrode material via an intermediate layer of a conductive metal oxide, the metallic end contacts containing silver, the diffusion of silver from the end contacts to the layers of electrode material is suppressed effectively in that the electrode material consists of palladium with 1 to 10% by weight of lead. On account of this, the end contacts can be readily manufactured from a paste, and delamination, cracking and the formation of cavities in the vicinity of the end contacts are suppressed.

  • Patent number: 4910638
    Abstract: In a multilayer capacitor, which is made of alternate layers 1 of a dielectric oxidic ceramic material and an electrode material 2, and which is provided with metallic end contacts 4 which electrically conductively contact a prescribed part of the layers of electrode material via an intermediate layer 3 of a conductive metal oxide, the metallic end contacts containing silver, the diffusion of silver from the end contacts to the layers of electrode material is suppressed effectively in that the intermediate layer is a heterogeneous layer which, apart from the conductive metal oxide, contains glass particles, and in that the heterogeneous layer has a thickness of at least 1 .mu.m. On account of this, the end contacts can readily be manufactured from a paste, and delamination, cracking and the formation of cavities in the viscinity of the end contacts are suppressed.
