    摘要： This invention provides a surface acoustic wave device mounted module which is miniature, light, and highly reliable. The surface acoustic wave device mounted module also has excellent frequency characteristics. The surface acoustic wave device mounted module includes a multilayer substrate which has at least one layer of a shield pattern, input-output electrodes, grounding electrodes, through holes used for connecting electrodes, and a surface acoustic wave element. The surface acoustic wave element has metallic bumps, which are transfer-coated with a conductive resin, on electrode pads and an insulating resin around the surface acoustic wave element. The electrode pads are input-output terminals and grounding terminals formed on the surface acoustic wave element. Continuities between the input-output terminals and the input-output electrodes, and between the grounding terminals and the grounding electrodes are established by the through holes. An electrode pattern is formed on the surface of the multilayer substrate facing and surrounding the surface acoustic wave element. A metallic lid is attached to the electrode pattern by a solder or a conductive resin so that the surface acoustic wave element is sealed in an airtight condition. The electrode pattern is connected to the grounding electrodes by the through holes.

    摘要： A semiconductor laser apparatus includes a semiconductor laser for emitting a light beam. The semiconductor laser has, as an external cavity, a quadruple light wave mixing optical phase conjugate element for inverting a spatial phase of an incident light beam. The apparatus further includes a pair of pump light sources which are arranged such that a superimposed portion of spectra of wavelengths of three light beams including two pump light beams emitted from the pair of pump light sources and entering into the optical phase conjugate element and another light beam emitted from the semiconductor laser is narrower than the spectral width of wavelengths of each of the three light beams. This enables the laser apparatus to generate an oscillating output wavelength of extremely narrow spectral width.

    摘要： A voltage-dependent resistor comprising a sintered body comprising ZnO as a major part and additives wherein at least 10 weight percent of the ZnO is composed of ZnO grains having a grain size in the range from 100 to 500 microns; and method of making the same wherein the starting mixture comprises ZnO grains having a grain size in the range from 20 to 200 microns. This voltage-dependent resistor has both a low C-value and a high surge energy withstanding capability. It also has a low leakage current at a high temperature due to the addition of an antimony component as a spinel type polycrystalline Zn.sub.7/3 Sb.sub.2/3 O.sub.4.

    摘要： A resonator ladder surface acoustic wave (SAW) filter, which has a wide and flat pass band without spurious signals therein is provided. An input electrode, a serial arm SAW resonator, an output electrode, a parallel arm SAW resonator and a ground electrode are respectively formed on a 41.degree.-rotated Y-cut X-propagation lithium niobate substrate. The serial arm SAW resonator comprises a pair of interdigital transducers (IDTs) to excite SAW, one of which is connected to the input electrode. The output electrode is connected to the other IDT of the serial arm SAW resonator. The parallel arm SAW resonator comprises a pair of IDTs to excite SAW, one of which is connected to the output electrode. And the ground electrode is connected to the other IDT of the parallel arm SAW resonator. The IDTs are metal films of Al or Al-based alloy, and the thickness of the metal films ranges from 2.5% to 7.5% of the electrode cycle of the IDT of the parallel arm SAW resonator.
