    摘要： In a surface acoustic wave filter constituted with a ladder of resonators having a resonance frequency or an anti-resonance frequency, an input current flowing into a resonator in a parallel arm at the first stage from the input is so large as to deteriorate its lifetime caused from a heat generation by the resistance of the thin film wiring. As a measure to this problem, bonding wires (30, 31) connected onto points on connection electrodes (130, 131) for connecting an end of each of plural comb teeth electrodes 111 forming the resonators R.sub.s1 & R.sub.p1, or on a lead conductor (130-1) extended longitudinally from the connection electrode, are allotted at both sides of a center line (C1) of the plural comb teeth electrode group. Furthermore, a bonding wire may be connected substantially onto the center line C1 as well. It is preferable for the bonding wires to be located substantially symmetric with respect to the center line C1. It is preferable that the width along the longitudinal direction of the comb teeth electrodes is larger than a width of the comb teeth electrode.

    摘要： In order for the temperature dependence of the strip out field of a magnetic garnet crystal film (54) to match the temperature dependence of the residual magnetization of a permanent magnet (56) for applying a bias magnetic field in a magnetic bubble memory chip (2) after conductor paterns are formed thereon, it is necessary that the temperature coefficient of the collapse field of the magnetic garnet crystal film (51) be from 0.01 to 0.04%/.degree.C., in terms of an absolute value, greater than the temperature coefficient of the above-mentioned residual magnetization (56). The present invention achieves this by increasing the degree of substitution of Lu ions for Fe ions in the octahedral sites constituting the unit lattice of the magnetic garnet crystal. As a result, an operating temperature range about twice as wide as the conventional operating temperature range is ensured.
