Abstract: In an outboard motor steering system, the engine speed is detected as a value indicative of the speed of the boat and a current value for operating a steering hydraulic cylinder is determined to decrease with decreasing engine speed. The current value can therefore be determined in accordance with the steering load to reduce electric power consumption. Moreover, owing to the fact that the drive current is determined as a function of steering load, it is possible to prevent the output of the cylinder from becoming excessive relative to the steering load, thereby ensuring that the steered angle tracks a desired steering angle with good accuracy.

Abstract: A mass spectrometer is disclosed comprising a segmented linear ion guide or ion trap. Ions are confined radially within the ion guide or ion trap by the application of an AC or RF voltage to the electrodes forming the ion guide or ion trap. A quadratic DC potential is applied along the axial length of the ion guide or ion trap in order to cause trapped ions to perform simple harmonic motion within the ion guide or ion trap. The frequency of the oscillations of the ions is detected using one or more inductive detectors.  The mass to charge ratio of the ions can then be determined from the determined frequency of oscillations.
