摘要： A surface acoustic wave element includes a piezoelectric substrate (10), a waveguide (14) provided on the piezoelectric substrate to guide a surface acoustic wave therethrough, and an input transducer (11) provided on said piezoelectric substrate to generate the surface acoustic wave. The input transducer is arranged to concentrate the surface acoustic wave so as to couple it with the waveguide and to oscillate the surface acoustic wave within a range of an aperture angle of the waveguide.

摘要： A complementary acoustic charge transport circuit element comprises first and second buried channels. Each of the channels is comprised of a piezoelectric semiconductor and each channel has a source through which charge is injected and a drain through which charge is extracted. A transducer propagates an acoustic wave through each channel and the propagated waves transport the charge between the sources and the drains. A source and/or a drain of one channel is connected in parallel with the corresponding source and/or drain of the other channel. The waves are complementary at the interconnected ones of the sources and/or the drains.

摘要： Method and device for delaying an electrical signal, the method and device being useable in various signal processing applications. A buried channel (41) is formed by disposing a portion of a layer of piezoelectric semiconductor material (40) between confining layers (50, 30). A surface acoustic wave is established in the piezoelectric semiconductor material via an input transducer (55). Majority carriers are depleted from the channel, and an electrical signal is injected into the channel via an interdigital transducer (55). A delayed version of the electrical signal, which had been carried along by the surface acoustic wave, can then be extracted from the channel via an output diode (71).

摘要： A surface acoustic wave device consists of a substrate of a piezo-electric material provided with an input transducer T' i and ten output transducers T' 01 .... T' 010 spaced apart along the substrate. The output transducers are arranged in two tracks (20, 30) and are spaced apart so that a surface acoustic wave, launched in a propogation direction P and received at the output transducers will be subject to respective delays. These delays exclude one or more delays which would have arisen if the output transducers had been arranged on the substrate with the same relative spacings but in a single track only.
摘要翻译：表面声波装置由设置有输入变换器T min I的压电材料的基板和沿着基板间隔开的十个输出换能器T min 01 ... T min 010组成。输出传感器布置在两个轨道（20,30）中并且间隔开，使得以传播方向P发射并在输出换能器处接收的声表面波将受到相应的延迟。这些延迟排除了一个或多个延迟，如果输出传感器已经以相同的相对间距排列在基板上，而仅在单个轨道中，则会出现这种延迟。

摘要： An elastic surface wave apparatus comprising a piezoelectric substrate, a pair of input- and output-transducers located on a diagonal line and a multi-strip coupler arranged between the two transducers. In the apparatus, the spacing between electrodes in at least one of the transducers is 3(Alpha)/4 ((Alpha): the wavelength of elastic surface waves). The filtering characteristic of the multi-strip coupler eliminates resultant spurious frequency response.
