    摘要: A SAW duplexer includes a first SAW filter having a passband with a relatively low frequency, and a second SAW filter having a passband with a relatively high frequency. The first and second SAW filters each have a ladder-shaped circuit configuration. A bridging inductor is connected in parallel to at least one serial arm resonator in the second SAW filter. The bridging inductor includes a coiled portion provided on a multilayer package substrate. The coiled portion is defined by connecting first to third wires provided on first to third layers by via-hole conductors. First, third, and fifth via-hole conductors that define a coil return wire portion are disposed inside the coiled portion.

    摘要: According to the present invention, a cylindrical side wall is provided in a housing so as to surround an outer periphery of a stopper member. Further, an end surface of the side wall is higher than a top surface of outermost periphery of the stopper member. Oil otherwise scattered is received by the side wall for collection. Oil is thus prevented from scattering even if during manufacturing, the amount of oil dripped between the shaft and the oil-impregnated bearing is not strictly controlled, so that a slightly excessive amount of oil is dripped. Therefore, the present motor device enables manufacturing operations to be favorably performed, and is reliable having a long lifetime.
