摘要:
A heated evaporator housing is provided at its inlet with an ultrasonic atomizer for reducing monomer to small droplets and a permeable porous body completely occupying a cross section of the housing between the inlet and the outlet. A vacuum pump and a reaction chamber for coating substrates are provided downstream of the outlet.

The invention relates to an arrangement for coating or etching substrates. In this arrangement an HF substrate bias voltage is generated without contact. For this purpose plasma sources are equipped with a bias pot which is disposed at the dark space distance from a substrate carrier and acted upon by HF. Depending on the source used, the bias pot can be constructed as an independent unit or as a component part of the source connected so as to be conducting-for example as an HF magnetron. Via this coupled-in HF power the dc potential on the carrier, and consequently the ion bombardment on the substrate, can be set specifically.

The invention relates to an electrode configuration for a device for generating a plasma. RF is coupled contactlessly via a capacitive coupling electrode disposed at the dark space distance into a carrier backside of a coating installation. Dark space shields on the coating side define the plasma zone and prevent the formation of parasitic plasmas. HF substrate bias voltage on the moving substrate carrier is achieved with a defined plasma zone and the development of parasitic plasmas is avoided.

The invention relates to a method for producing an adsorption heat exchanger, which is characterized by the following Steps: producing a heat exchanger structure; forming an adhesive layer (5) on the heat exchanger structure; filling the heat exchanger structure with a sorbent material (6.1); removing from the heat exchanger structure portions of the sorbent material that have bonded only weakly or not at all to the adhesive structure.
摘要:
Blends of olefin polymers and syndiotactic vinyl polymers are produced by the catalytic polymerization of olefins and aromatic vinyl compounds or methacrylate esters as vinyl compounds in inert diluents in the presence of a catalyst mixture of transition metal compounds, metalloxane compounds and metal alkyl compounds.The blends have a finely dispersed distribution of the blending components and are suitable for the production of films, sheets, fibers, panels, coatings, pipes, hollow objects, injection molded products and foams.
摘要:
In an internal combustion engine there is provided a cylinder head; a plurality of cylinder head bolts for securing the cylinder head to a cylinder block; at least one engine cylinder; at least two intake valves and two exhaust valves controlling the flow of gases into and from the engine cylinder. A plane defined by the intake valves and a plane defined by the exhaust valves extend at an angle of between 0.degree. and 15.degree. to one another and have an inclined orientation to the longitudinal engine axis. An overhead camshaft extends parallel to the engine axis and is situated in a zone bounded by the cylinder head bolts. Respective valve bridges interconnect the intake valves with one another and the exhaust valves with one another, and rocker arms connect respective cams of the camshaft with the valve bridges, whereby the intake valves are simultaneously operated by one cam and the exhaust valves are simultaneously operated by another cam.

摘要:
A pane made of glass or plastic, whose optical degree of reflection can be controlled by switching between two different interference conditions. As a result, the transmissibility with respect to sun radiation can be reduced very efficiently and an excessive heating of glazed objects can be prevented. Preferred applications of the invention are the climate control of motor vehicles, rail vehicles, airplanes and buildings.
