摘要： An index generating unit divides each name data of search target data both into words and into characters, calculates start and end scores showing a start and an end of each of the words and start and end scores showing a start and an end of each of the characters, links them to each entry word which constructs the name data as a list (a name ID, a position, and start and end scores), and stores this list in an index storage unit. A searching unit decomposes an input character string into partial character strings, acquires corresponding candidate entries from the index storage unit, and judges the continuity between candidate entries on the basis of lists to add a comparison score according to the continuity to a candidate entry.

摘要： A first supporting section 30 is provided between a substrate section 40 and a second supporting section 20. The first supporting section 30 is structured by, e.g., a film formed from a material having a higher acoustic impedance than a piezoelectric body 11 and the substrate section 40, or a film formed from a material having a smaller Q value than the piezoelectric body 11 and substrate section 40. By inserting the first supporting section 30, most vibration from the second supporting section 20 toward the substrate section 40 is reflected (arrow a), and also a vibration having been transmitted to the substrate section 40 from the second supporting section 20 is prevented from reflecting at the bottom of the substrate section 40 and then returning in a direction of the vibration section 10 (arrow b).

摘要： The area of an opening C of a cavity 31 is equal to or greater than the area of a horizontal cross section D of a vibrating section 10. The vibrating section 10 is placed on a support section 20 at a position such that a vertical projection of the vibrating section 10 onto a substrate 30 is accommodated within the opening C of the cavity 31. Moreover, the sum of a vertical thickness t1 of the vibrating section 10 and a vertical thickness t2 of the support section 20 is equal to one wavelength of a resonance frequency fr of an acoustic resonator 1 (one wavelength=t1+t2), while the thickness t1 of the vibrating section 10 and the thickness t2 of the support section 20 are different from each other (t1≠t2). Thus, neither the thickness t1 of the vibrating section 10 nor the thickness t2 of the support section 20 is equal to the half wavelength of the resonance frequency fr.
