Abstract: A transmitting/receiving filter (filter device) according to one embodiment of the present invention is provided with a transmitting filter, a receiving filter, and a support substrate. The transmitting filter includes a first resonator constituted of a BAW device (FBAR, SMR). The receiving filter includes a second resonator constituted of a Lamb wave device. The support substrate supports both the transmitting filter and the receiving filter. The transmitting filter and the receiving filter are constituted of elastic wave resonators that resonate at different oscillation modes from each other, which allows miniaturization of the support substrate to be realized while preventing oscillation interference between the two filters.

Abstract: A method of manufacturing a capacitor includes: anodizing a metal substrate in two stages by applying two different voltage so as to make first and second holes having different pitches, distributed randomly in an oxide substance; filling the first and second holes with an electrode material, respectively, to form first and second electrodes; connecting the first electrodes to a conductive layer formed on one surface of the oxide substance; and connecting the second electrodes to another conductive layer formed on another surface of the oxide substance.

Abstract: A capacitor element includes a pair of conductive layer, a plurality of first electrodes and second electrodes, and insulation caps for insulating these electrodes from the conductive layers. By anodizing a metal substrate in two stages, holes filled with the first electrodes and holes filled with the second electrodes are randomly distributed.

Abstract: A piezo drive system includes an elastic fixing frame, a drive element, a rod, and a rotor. A vamplate portion is formed on the outer surface of the rod. One end of the rod is secured to around the center of a face of the drive element. The rotor consists of a cylindrical portion and a disk portion, and can rotate relative to the rod. Protrusions are formed on the inside of a top surface portion of the fixing frame to push against the disk portion. Using the drive element, the rod rotates while tilting and makes a surface contact with the vamplate portion, producing friction. Consequently, the rotor is rotated.
