Title: Ground/working implement depth control system
IPC: G05G1/01
Filed: 1983-11-18
Granted: 1988-09-07
Abstract: The working depth of an implement attached to the 3-point hitch of a tractor is normally controlled by a draft load error signal formed as the difference between a load set point signal and an actual load signal provided by a draft sensor. For lowering the implement into the ground and raising it a depth position lever (50) actuates a transducer (54) to provide a position set point signal A(3) which is compared with an actual position signal from another transducer to form a position error signal. A large position error takes precedence over a smaller load error. In order to provide the load set point signal without the need for a separate lever, a swith (58, 60) is mounted on the lever (50) and, when depressed, causes the draft load set point signal to increase up to the desired value as the implement is lowered into the ground by pushing the lever (50) forwards.

Abstract: A method of measuring the electrical resistance of thin metallic films manufactured under the influence of a plasma. The measurement proceeds by means of a direct current resistance measurement according to the principle of a two point or four point measuring method. The electrical resistance is determined either in the case of at least one measuring or test current, and the voltage connected to the measuring contacts is measured when no measuring or test current is sent through the film, or the electrical resistance is determined in the case of at least two different measuring or test currents of known magnitudes. The measuring methods are applied in the case of manufacture of metallic layers in semiconductor technology, in particular also for the measurement of the ion current injected in the film by the plasma as well as for the determination of variations in the coating rate.
