摘要:
A multistage lock chamber device with at least two lock chambers, a first pump set for evacuating a first lock chamber, and a second pump set for evacuating a second lock chamber. The first pump set (P1) may evacuate both the first and the second lock chamber, or both jointly. The first pump set may also be utilized as a prior pumping stand of the second pump set. Additionally, an integrated third pump set can be utilized as a pre-pumping stand for the second pump set and/or first pump set. Alternately or additionally, the device can include at least one buffer unit, whose buffer volume is being utilized to produce a sudden decline in pressure inside the lock chamber by means of pressure equalization.
摘要:
Plastic bottles as well as other hollow bodies are given thin functional layers by means of high vacuum coating devices. The relevant process takes place in high vacuum. The bottles to be coated as well as the coated bottles are inserted into a high vacuum chamber (20) through a sluice, which consists of carrousel drum unit. Due to the difference of pressure in the atmosphere and the high vacuum chamber, carrousel within the drum suffers a displacement or tipping, which makes the sealing of the carrousel with respect to the drum difficult. Hence the invention proposes a sluice system consisting of two sluices (23, 25) of the mentioned type, which are connected with one another by means of an intermediate vacuum chamber (22). It is thus achieved that the load due to the pressure on each drum (3) decreases, so that each sluice (23, 25) functions with lesser tendency to develop faults.
摘要:
An electrode arrangement for the plasma-aided coating of a substrate (3) with a layer of material comprising at least one first and a second material component and for the production of a plasma discharge, more especially an arc discharge (35), having an anode arrangement (5), which provides the first material component at an anode material surface (13) for evaporation, and a cathode arrangement (7), which provides the second material component at a cathode material surface (25). The electrode arrangement is characterized in that the cathode material surface (25) is constituted by an evaporation-active part (27) supporting the plasma discharge (35) and an evaporation-inactive part (41) not supporting the plasma discharge. Preferably, a motion-producing means (49) is provided for moving the evaporation-inactive part (41) over the cathode material surface (25) in order to reduce deposit of material due to he first material component on the cathode material surface (25).

A vacuum chamber for flat substrates features transport rollers for transport of the substrates. These transport rollers are held from the sides in bearings and are additionally braced between the bearings by at least one middle bearing. These middle bearings are each located on a plunger which is guided hermetically through an opening in the bottom of the vacuum chamber and is braced against a support underneath the bottom.

The invention relates to a flooding chamber for coating installations, with which shorter flooding times, and therewith shorter clock cycles, can be attained. Two flooding means are therein utilized, between which a substrate is disposed symmetrically. The flooding means direct a gas jet directly onto the substrate. Hereby the substrate is fixed between the flooding means.
