    摘要: A thin-film bulk acoustic oscillator comprises: a base; a barrier layer disposed on the base; a lower electrode disposed on the barrier layer; a piezoelectric thin film disposed on the lower electrode; and an upper electrode disposed on the piezoelectric thin film. The piezoelectric thin film includes a columnar crystal that extends in the direction intersecting the film surface. The top surface of the piezoelectric thin film is flattened by polishing so as to have a root mean square roughness of 2 nm or smaller.

    摘要: According to the present specification there is disclosed a porous film having a number of throughholes extending from one side to the other side, obtained by molding into a sheet form a resin composition comprising an ethylene-.alpha.-olefin copolymer, a thermoplastic elastomer and an inorganic filler and then subjecting the sheet to stretching for orientation. Said porous film has excellent flexibility, stretchability and moisture permeability. These properties are made possible by using individual components in particular proportions, molding the resulting composition into a sheet form and then stretching the sheet to form fine throughholes therein so as to have a moisture permeability of 2,000 g/m.sup.2.24 hr or more.

    摘要: A complex circuit component for a video signal circuit in a television receiver set has a single substrate, on which a first ceramic trap for removing speech carrier wave together with an inductor for that trap, a second trap for removing color subcarrier wave, and a delay circuit coupled with output of said second trap are mounted. The capacitors for those circuits are implemented by a pair of conductive patterns deposited on front surface and rear surface of the substrate. The capacitor for said first ceramic trap is subject to trimming so that the characteristics of the trap is adjustable.
