    Abstract: In a surface acoustic wave device comprising an inter-digital electrode on a surface of a substrate wherein said substrate is a langasite single crystal belonging to a point group 32, a combination of a cut angle of the substrate out of the single crystal and-a propagation direction of surface acoustic waves is optimized. This makes it possible to achieve a surface acoustic wave device comprising a substrate having a temperature coefficient of SAW velocity, TCV, the absolute value of which is small, a large electromechanical coupling factor k.sup.2, and low SAW velocity. It is thus possible to achieve a filter device which is improved in terms of temperature stability, has a wide passband, and is reduced in size, especially an intermediate-frequency surface acoustic wave filter having improved characteristics best-fitted for mobile communication terminal equipment.

    Abstract: A push switch is capable of performing a first switching operation and subsequently a second switching operation when a pressing force is applied to the switch. The push switch includes (a) an insulating membrane having at least one dome with at least a portion thereof overlaid by or serving as an inner conductor and at least a portion of its outer periphery overlaid by or serving as an outer conductor, (b) an insulating substrate having thereupon an inner pole contact disposed at a position opposing to the inner conductor and an outer pole contact disposed at a position opposing to the outer conductor, respectively, and (c) a spacer placed between the insulating membrane and the insulating substrate for spacing the conductor apart from the pole contacts during the time when no pressing force is applied to the switch. When a light pressing force is applied to the dome, the outer conductor will first come in contact with the outer pole contact causing a first switching operation to take place, and subsequently with a further pressing, the inner conductor will come in contact with the inner contact causing a second switching operation to take place.

    Abstract: For the purposes of solving a problem due to a fly ash and HF in an exhaust gas, maintaining the activity of calcium carbonate as an absorbent, and recovering a high-purity gypsum, there is here provided a method for desulfurizing an exhaust smoke which comprises the steps of leading the exhaust gas containing the fly ash to a gas absorbing step, removing SO.sub.2 and the fly ash from the exhaust gas by the use of an absorbing solution slurry containing calcium carbonate as an absorbent in the gas absorbing step, and blowing air into the absorbing solution slurry circulating through the gas absorbing step to oxidize it and to thereby produce the gypsum, the aforesaid method being characterized by drawing a portion of the absorbing solution slurry therefrom, leading it to a magnetic field to separate and recover the fly ash from the absorbing solution slurry, and then returning, to the gas absorbing step, a portion or all of the absorbing solution slurry from which the fly ash has been separated.
