摘要:
The invention relates to a method for the blow moulding and coating of a body, comprising the following steps: a plastic material is introduced into a coating reactor (1) with at least one opening (3), through said opening (3) and a body is formed by injection of a gas through said opening (3), the body and/or the chamber of the coating reactor, surrounding the same, is evacuated and a precursor gas and gases for a gas atmosphere are introduced into the body and/or the surrounding coating reactor (1). The method is characterised in that within the body (7) and/or the surrounding chamber of the coating reactor (1), pulsed microwave energy is injected such that a coating is deposited on the inner and/or outer surface of the body (7) by means of pulsed PICVD (Plasma Impulse Chemical Vapour Deposition).

The aim of the invention is to render vacuum coating of substrates (11) more economical. Said aim is achieved by a device (1) for vacuum-coating substrates, comprising a conveying device, at least one coating station (7, 71, 72, , 7N) which is provided with several coating locations (91 - 94) and is conveyed on the conveying device, an evacuating device, and a device for rotating the coating locations (91 - 94) on the conveying device.
摘要:
An apparatus for producing holes in dielectric workpieces in the form of thin sheets and substrates, in particular of glass or glass-like materials and semiconductors is provided. The apparatus includes individual high-voltage electrodes that are symmetrically arranged on an electrode holder around the hole to be produced in the workpiece. The apparatus also includes individual counter electrodes that are arranged on a counter electrode holder. The electrodes and counter electrodes can be connected in a permutating manner to a high-voltage source for the discharge of high-voltage flashovers.

The invention relates to a method and device for the simultaneous coating and moulding of a body (11) comprising the following steps: two mould halves (1.1, 1.2) of a moulding tool (1) for moulding a moulded body are brought together and mounted on the unit, an injection material is introduced into the mould halves (1.1, 1.2), so as to produce a moulded body (11), the moulded body (11) is evacuated, a gas is introduced into the moulded body (11), the plasma in the moulded body (11) is ignited, such that a coating is deposited on the inner side of the moulded body (11). After the completion of the coating the mould halves (1.1, 1.2) are separated, whereupon the moulded body drops out.

This application concerns a method and devices for creating a multiplicity of holes (12) in thin workpieces (1) of glass or glass-like materials and semiconductors. Often, laser beams (41) are directed onto predetermined perforating points (10) of the workpiece (1) in a wavelength range between 1600 and 200 nm and with a radiant intensity that leads to local, athermal destruction of the workpiece material (1) in each case along a filamentary channel (11). After that, the filamentary channels (11) are widened to the desired diameter of the holes (12).
