Title: Ionisation of stream of particles, and high speed coating - in vacuum chamber contg. hollow cathode and magnet so sputtering is combined with ion plating
Inventor: REISSE GUENTER DR RER NAT
IPC: H01J37/317
Filed: 1979-12-06
Abstract: A vacuum chamber contains a hollow cathode surrounded by a magnet creating a tunnel-shaped, inhomogeneous and closed magnetic field inside the cathode. Gas and/or vapour is fed into the chamber, and a neutral or partly ionised stream of gas or vapour particles is created in the cathode, which functions like an electron trap. A voltage is applied between the cathode and an anode to create both a cathode discharge and a ring gap discharge superimposed on each other, so the resulting plasma ionises the particles which are accelerated towards a substrate. The hollow cathode pref. consists of (I) carbon, using a CH4-Ar mixt. to form the particle stream; or (II) pure or doped Si, using SiH4 to form the particle stream. Used in microelectronics, opto-electronics, optics, or for coating surfaces to prevent corrosion or wear.
Patent DE-2951123-A1 (DE)
Title: Brightness control of groups of discharge lamps - employing load sensitive regulating circuit allowing successful lamp starting at times of reduced brightness
IPC: G05F1/455
Filed: 1979-12-19
Abstract: A typical application for the control circuit is to ceiling mounted lighting in offices where the general brightness level of the lamps is regulated w.r.t. the intensity of natural daylight entering the room. The regulator controls a block of individually switched lamps. In order to ensure that, at a time when the regulator has turned the lamp voltage down, a further lamp can be successfully switched on, it is necessary to make the regulator load sensitive. This is achieved by having two input signals to the regulator circuit taken from separate points (A,B) on the supply line. These tapping points are typically between 30 and 50 cms apart. Of the two input channels to the amplifier (V) of the regulator one has a time delay (C3). By this means, step change changes in load, for example caused by switching on a lamp, are detected and a suitable transient step change made in the regulating device (LG) setting. In this example, it is a transient voltage increase to ensure that the incoming lamp strikes, after which the voltage across the total load returns to the original level.
Patent DE-3000977-A1 (DE)
Inventor: LEBLANC JEAN
IPC: F02M59/36
Filed: 1980-01-12
Abstract: A fuel injection apparatus for internal combustion engines is proposed (FIG. 1), in which the onset and end of injection are determined by a hydraulically actuated control slide. The injection pumps of the apparatus, which are preferably combined with an injection nozzle to make a pump/nozzle unit, having a central magnetic valve assembly comprising two magnetic valves switched hydraulically in parallel, which valve assembly is inserted in a connection between a control pressure line, which can be placed under control pressure (PS) from a source of control fuel, and a low-pressure line which is under supply pressure (PV). In order to initiate the onset of injection, the control slide is placed under control pressure (PS) by the valve assembly via a distributor apparatus and closes an overflow channel leading out of the pump work chamber. In order to control the end of the injection, the control slide, during its return stroke, relieves this overflow channel toward a low-pressure line. The control pressure (PS) in the control pressure line required for actuation of the stroke movement of the control slide is built up by means of the valve assembly as a result of blocking the outflow from this line.
