Patent number: 6608351Abstract: The performance of high-voltage devices is often influenced by charge-creep effects in the package. In order to avoid the resultant degradation, a bleeder may be used between the device and the package. However, it has been found in practice that the use of a high-resistive bleeder may lead to a certain instability of the device during operation. According to the invention, the bleeder (8) is provided with a plurality of conductive regions (12, 13) which are distributed in such a way that, when a high voltage is applied across the bleeder, a non-linear potential profile across the bleeder is obtained, which harmonizes with the ideal potential profile without the bleeder, instead of a linear profile which would have been obtained in the absence of said conductive regions due to charge-loading effects, and which would result in the above-mentioned instability effects.Type: GrantFiled: June 1, 2000Date of Patent: August 19, 2003Inventors: Constantinus Paulus Meeuwsen, Hendrik Gezienus Albert Huizing, Adrianus Willem Ludikhuize

Patent number: 4949367Abstract: An X-ray analysis crystal is also curved in a direction transverse to the dispersion direction to increase the radiation efficiency. As a result of this radiation diffracted at the crystal is focused towards a detector input.

Patent number: 4806328Abstract: Monolithic glass members are prepared by first hydrolyzing a solution of tetraethoxysilane in alcohol with an acid medium, and then gelating in a basic medium while using acid and base mediums to form compounds that volatilize during drying and sintering the gel. Substances, if any, which in the form of oxides can form a glass with SiO.sub.2, are added after hydrolyzing and prior to gelation.Type: GrantFiled: September 30, 1985Date of Patent: February 21, 1989Assignee: U.S. Philips CorporationInventors: Joseph G.

Patent number: 4780899Abstract: A crystal for an X-ray analysis apparatus is mounted on a carrier of an amorphous material whose bonding surface preferably obtains its desired geometry by grinding and polishing. Using a suitably transparent carrier, use can be made of a UV-curable type of adhesive which is irradiated through the carrier. The thickness of the layer of glue can be checked, if desired, via the same path. Because no disturbing background radiation is generated by an amorphous carrier, local irregularities are avoided, and better thermal adaptation of carrier and crystal material is feasible, such a crystal will contribute to a substantially higher resolution when used in an X-ray analysis apparatus.Type: GrantFiled: April 15, 1986Date of Patent: October 25, 1988Assignee: U.S. Philips CorporationInventors: Cornelis L. Adema, Cornelis L. Alting, Wilhelmus H. J. M. Gevers, Albert Huizing

Patent number: 4763398Abstract: The invention provides a method of manufacturing a hollow metal light conductor in which at least one metal layer is provided on a core of a synthetic resin material, for example, polymethylmethacrylate, after which the core is removed, and a metal tube is formed. The core is preferably removed by slightly elongating the core so that the cross-section is reduced, after which the metal light conductor can be pulled from the core. The reflecting metal layer on the inside surface of the light conductor preferably is of aluminium. The invention provides a hollow metal light conductor, for example, for use in an optical spectrometer, which is also suitable in particular to be used for light having a short wavelength, to less than 200 nm.Type: GrantFiled: September 8, 1986Date of Patent: August 16, 1988Assignee: U.S. Philips CorporationInventors: Albert Huizing, Willy J.
