    摘要: A SAW device has interdigital electrodes on a substrate, wherein the substrate is obtained by slicing a single crystal represented by the chemical formula: La3Ta0.5Ga5.5O14 (LTG) at a cut angle. The cut angle and the direction of propagation of SAW along the substrate are optimized so that the substrate may have a low SAW velocity and an increased electromechanical coupling constant. This enables to reduce the size of the SAW device and broaden the pass-band width thereof as a filter, providing satisfactory characteristics especially as a SAW filter of intermediate frequency for mobile communication terminals. The SAW device has a minimal loss since SAW energy concentrates in the propagation direction.

    摘要: A surface acoustic wave device has a piezoelectric substrate whose properties include electromechanical coupling coefficient advantageous to widening passband width and SAW velocity advantageous to achieving a compact surface acoustic wave device. The piezoelectric substrate is composed of the single crystal represented by chemical formula Sr3TaGa3Si2O14 belonging to point group 32. For example, cut angle of the single crystal and propagation direction of the surface acoustic wave are in region 1-1, wherein said region 1-1 represented by Euler angles (&phgr;, &thgr;, &psgr;) satisfies &phgr;=25° ˜35°, &thgr;=20° ˜90°, &psgr;=−40° ˜40°. These angles may be in range 1-2, wherein said range 1-2 satisfies &phgr;=25° ˜35°, &thgr;=20° ˜90°, &psgr;=−25° ˜25°.

    摘要: This invention is related to a wet gas process which would not require a spray pump, and which would allow the absorption liquid to be recovered smoothly even if the flow velocity of the gases entrained to the liquid should decrease. A wet gas processing apparatus in which the absorption liquid collected in the first liquid storage tank is sprayed in a specified direction (which may be upward, horizontal or downward) by a discharge unit consisting of spray nozzles (14) or the like in the absorption tower. The sprayed liquid is brought into contact with the exhaust gases which are conducted into the tower, and the targeted components of the gases are absorbed and removed. This processing apparatus is distinguished by the following. The first liquid storage tank for the absorption liquid comprises a pressure tank (11) which generates a pressurized gas in the space above the surface of the collected liquid (11a). The increased pressure of the pressurized gas is employed to spray the liquid collected in the pressurized tank from the spray nozzle unit in the absorption tower. This apparatus is further distinguished as the following. This invention has overflow ports which generate a virtually horizontal overflow or source flow. The absorption liquid propelled by the overflow ports makes orthogonal contact with the flow of exhaust gases, which results in both atomization of the liquid and liquid-vapor contact.
