Abstract: Fluid fuel traveling through a fuel line is ionized by the action of infrared rays emitted from a ceramic material disposed within two cases containing multiple compartments through which the fuel line extends. Both cases contain pairs of permanent magnets which establish magnetic flux patterns tending to break-up the fuel into small particles. A resonator is mounted in a compartment of one case and a resonance vibrator is mounted opposite said resonator in a compartment of the other case. Two layers of a material emitting infrared rays are disposed on opposite sides of the fuel line with an additional magnetic member being disposed between said layers.

Abstract: A filter for suppressing surface to surface interference for a satellite communication receiver which utilizes a surface acoustic wave (SAW) element. The SAW filter comprises two inter-digital transducers for input and one inter-digital transducer for output, all three transducers are constructed and arranged on a piezoelectric substrate. The widths of the adjacent portions of electrodes and the spaces between the electrodes of the input inter-digital transducers are adjusted based upon the principle of a transversal filter so that the frequency responses of the input interdigital transducers have a predetermined band width and a reduced gain of a frequency range where an interference signal exists respectively.
