摘要:
An assembly-target-object-and-assembly-component carrier pallet carries thereon a target object (semi-finished product) 2 and a plurality of assembly components arranged, as viewed in plane, on a straight line which passes through a predetermined attachment position on the target object where the predetermined assembly component is to be attached. This allows a minimum of moving parts in the attaching device which attaches the assembly components to the assembly target object. Therefore, the structure of an assembling apparatus is simplified and mechanical errors and assembly time are reduced, thereby improving assembling accuracy.

The invention provides a three-stage surface acoustic wave filter of the ladder type wherein the resonance frequency difference &Dgr;f2 between the resonance frequency frs2 of a serial resonator in an intermediate stage and the resonance frequency frp2 of a parallel resonator therein is set at a value greater than the resonance frequency difference &Dgr;f1 (&Dgr;f3) between the resonance frequency frs1 (frs3) of a serial resonator in each of front and rear stages and the resonance frequency frp1 (frp3) of a parallel resonator therein, whereby the filter is given a widened pass band while reliably retaining satisfactory characteristics comparable to those of conventional surface acoustic wave filters of small pass band width. The desired filter exhibiting such performance is available within a shorter period of time and with reduced labor.

In a resonator-type surface acoustic wave filter comprising a lithium tantalate substrate, lithium niobate substrate or lithium tetraborate substrate having a cut plane of high velocity, the direction of propagation of surface acoustic waves is set within the range of (40 deg to 90 deg, 40 deg to 90 deg, 0 deg to 60 deg) as expressed in Eulerian angles, and the frequency difference .increment.f between the resonance frequency frs of series resonators and the resonance frequency frp of parallel resonators is set within a predetermined range formulated with the center frequency, the capacitance Cos of the series resonators and the capacitance Cop of the parallel resonators taken as parameters. Optimum ranges of the required design parameters are thus clarified to assure the resonator-type surface acoustic wave filter of higher performance.
