    摘要： A method for manufacturing a reflective liquid-crystal display apparatus is provided. The method includes: forming, over a substrate, a first metal layer and a first insulating layer having an opening and a first through-hole in order; forming a metal portion filled in the opening and a first plug filled in the first through-hole, by forming a metal film over the first insulating layer and planarizing the metal film until the first insulating layer is exposed; forming, over the first insulating layer, a second insulating layer, a second metal layer having an opening, and a third insulating layer in order; forming, in the second and third insulating layer, a second through-hole that passes through the opening of the second metal layer and exposes an upper face of the first plug; and forming a second plug filled in the second through-hole, and a reflective electrode connected to the second plug.

    摘要： A valve timing control apparatus for an internal combustion engine includes a variable valve timing mechanism. The valve timing control apparatus sets target valve timing based on an operational state of the engine. The valve timing control apparatus detects actual valve timing. The valve timing control apparatus computes a control amount based on a deviation between the target valve timing and the actual valve timing, and based on a hold control amount. The valve timing control apparatus determines whether a learning execution condition for executing a learning operation of the hold control amount is satisfied based on a change direction of the detected actual valve timing. The valve timing control apparatus executes the learning operation when the learning execution condition is satisfied.

    摘要： A piezoelectric thin-film filter includes a first electrode pair having two or more first electrode fingers disposed on one main surface of a piezoelectric thin film and second electrode fingers disposed on the other main surface of the piezoelectric thin film so as to face the first electrode fingers. A second electrode pair includes two or more third electrode fingers disposed on the main surface such that the third electrode fingers and the first electrode fingers are disposed alternately with gaps therebetween and fourth electrode fingers disposed on the other main surface so as to face the third electrode fingers with the piezoelectric thin film therebetween. Insulating films are provided between the first and third electrode fingers. Each of the center-to-center distances Wa+Wm and Wf+Wm between the first and third electrode fingers that are disposed alternately is larger than a value twice the thickness T of the piezoelectric thin film.

    摘要： A piezoelectric resonator and a piezoelectric thin-film filter including the piezoelectric resonator. The piezoelectric resonator includes a piezoelectric layer disposed between a pair of conductive layers to form a vibrating region. Outer edges of the vibrating region each have a waveform. The vibrating region includes a peripheral portion extending along the outer edges of the planar shape and having a relatively small thickness; and a central portion extending inside the peripheral portion and having a relatively large thickness. The piezoelectric resonator is thus capable of suppressing long-wavelength spurious modes and short-wavelength spurious modes.
