Abstract: A radio-frequency (RF) power variable capacitor capable of operating at, at least, 50 watts in the MHz range. The capacitor has a composite HDK-NDK ceramic dielectric. The HDK (high dielectric constant) component comprises an active matrix of barium strontium titanate, for example. Acoustic resonances are reduced or eliminated by the addition of a metal or metalloid oxide such as magnesium borate (NDK—low dielectric constant), which acts as an acoustic resonance reduction agent (ARRA) in the RF power domain. The acoustic resonances which previously occurred under bias voltage 500 V or 1100 V in prior art RF power variable capacitors are eliminated by the addition of the ARRA.

Abstract: A swashplate-type axial piston machine includes a housing and at least one working channel extending through a distributor plate. The at least one working channel opens out at an outside on the housing at an associated working port. The at least one working channel includes a first section and a second section. The first section extends over the entire distributor plate. The second section is arranged entirely in the housing. The second section directly adjoins the first section. A first rotary bearing has an outer circumferential surface that defines a circular cylindrical reference cylinder about the axis of rotation.

Abstract: A method for producing ceramic components, includes providing a dispersing agent comprising at least one first and one second powder fraction of an oxide ceramic, and a third powder fraction of an inter-metallic compound mixed in a liquid. The first powder fraction comprises a nanoscale particle fraction with particle sizes ranging from about 2 nm to 200 nm and functions as a binder. The second powder fraction comprises a sintering additive. The share of the third powder fraction, relative to the sum of all powder fractions, has a volume share of between about 50% and about 95%. The method further includes forming a green body with aid of precipitation by electrophoresis from the mixture, the precipitation by electrophoresis of the powder fractions occurring simultaneously. The green body is then sintered in an oxidizing atmosphere to form a ceramic component.

Abstract: The present invention relates to dielectric ceramics, thin and/or thick layers produced therefrom and a method for the production thereof and the use of the dielectrics and of the thin and/or thick layers.
