Latest Patents

Hagiwara holds a patent for "Elastic surface wave devices and method for making the same." This invention provides a surface elastic wave device constituted by a unitary body of a piezoelectric plate having a pair of transducers thereon. The device is embedded in a casing, and the wave propagation of a surface elastic wave generated on the surface of the piezoelectric plate during excitation is prevented from being transferred to the casing. This is achieved by a thin film inserted between the casing and the wave propagation surface of the piezoelectric plate or by using a roll of flexible sheet as the casing. The device is advantageous due to its low spurious signal level without increasing insertion loss, ease of manufacture, and cost-effectiveness.
