摘要:
In a method for producing a multilayer encapsulation (1) of a piezo actuator (5) such that the piezo actuator (5) is protected towards the outside without having to use an additional enveloping housing-type structure, in order to produce the multilayer encapsulation (1), an electrically insulating elastic layer (10) is first applied to the surface of the piezo actuator (5), whereupon a metallic layer is applied to the electrically insulating elastic layer (10) so as to planarly cover the same.

In a method for the production of a gradient encapsulation layer 20 on a piezoelectric actuator 1, based on this gradient encapsulation layer 20, the piezoelectric actuator 1 does not 5 require an additional housing-like enveloping structure in order to be protected externally. The gradient encapsulation layer 20 is produced by cold gas spraying of particles having different material properties.

In a process for coating or bonding electronic components and subassemblies with reaction resin mixtures that are stable in storage at room temperature as a one-component system for several months, reaction resin mixtures are used, which contain the following components:a cationically hardenable, solvent-free epoxy resin;a triarylsulphonium salt with hexafluorophosphate, -arsenate or -antimonate as anion, with a mass concentration of 0.01 to 5% (relative to epoxy resin); anda benzylthiolanium salt with hexafluorophosphate, -arsenate or -antimonate as anion, with a mass concentration of 0.01 to 5% (relative to epoxy resin);as well as possibly customary additives.These reaction resin mixtures are hardened through UV radiation and thermally.
摘要:
A method of producing a surface wave component with a drain for pyroelectric voltage includes forming electrically-conductive structures on a piezoelectric substrate. The structures form an acoustic path comprising an electroacoustic transducer. The method also includes forming a high-resistance layer on an entire surface of the substrate and on top of the electrically-conductive structures, and removing the high-resistance layer from at least a region corresponding to the electroacoustic transducer, such that at least a region outside the acoustic path remains covered by the high-resistance layer.

The invention relates to methods for manufacturing a rotor (14) for an electric machine (13), having the following method steps: a) manufacturing a magnetic element (8) by bonding permanent magnets (1, 1′, 1″, 1′″) by means of a first adhesive, each permanent magnet (1, 1′, 1″, 1′″) having a side with a magnetic North pole (N) and a side with a magnetic South pole (S), the permanent magnets (1, 1′, 1″, 1′″) being arranged during bonding such that the sides of the magnetic North poles (N) or the sides of the magnetic South poles (S) form a common underside (3, 3′, 3″, 3′″) of the magnetic elements (8), the first adhesive having a hard consistency in the cured state; and b) bonding the underside of the magnetic element (8) to a yoke (12) by means of a second adhesive, the second adhesive being soft and elastic in the cured state. Furthermore, the invention relates to an associated rotor. The invention permits rational manufacture of a rotor having a permanent magnet for a machine, the permanent magnets being integrally fixed to the yoke of the rotor with high reliability.
