Abstract: An electric drive unit includes an electronic control and monitoring module integrally connected to an electric motor. The housing of the electric motor has a double-walled construction to form a water jacket with cooling water passages therein. The electronic module includes at least one high power component that requires cooling. This component is mounted directly on a cooling insert that extends through a recess in the electronic module housing and is inserted in an opening provided in the outer wall of the motor housing. In this manner, the cooling insert is integrated into the water jacket of the motor housing and is directly cooled by the cooling water flowing in the cooling passages. A very compact and reliable construction is achieved, in which the electric motor and the electronic module share a common water cooling circuit. External water hoses and external electrical connections between the electric motor and the electronic module are avoided.

Contact pins between the substrate of the power unit and the carrier of the control unit for the connection and contacting of the circuit arrangement of the power unit with the semiconductor components on the control unit. A housing body, which encloses the power unit and the control unit.

Abstract: A novel planar waveguide structure has been constructed by sintering substantially pure SiO.sub.2 layers in a He.sub.2 /BCl.sub.3 atmosphere. This results in the generation of a liquid phase of substantially lower viscosity than that of the deposited silica by itself. Since viscous sintering is enhanced by the presence of this liquid, consolidation occurs at lower temperature, e.g. 1000.degree.-1100.degree. C., than those used in the prior art, e.g. 1350.degree.-1500.degree. C. Much of the B.sub.2 O.sub.3 remains unreacted with the silica particles it helps to sinter, acting like a flux to bring about consolidation. This remaining B.sub.2 O.sub.3 is removed at the conclusion of the consolidation procedure by steam treatment at temperatures of 900.degree.-1100.degree. C. Some boron is incorporated into the silica layer, changing its CTE without substantially increasing its index.

Abstract: The object of the patent application is an electronic control unit with triggering and power components, in particular an ignition control unit, whose electronic circuit comprises various assemblies in hybrid technology. To reduce the assembly expenditure and costs for manufacture, while at the same time reducing the volume, the invention provides for the assemblies of the electronic circuit to be integrated in a hybrid circuit and arranged on a single common carrier element. This carrier element is designed as an electrically non-conductive ceramic carrier of Al.sub.2 O.sub.3, by which the electronic circuit of the control unit is electrically insulated from a heat sink.
