    摘要: An energy-trapping thickness-shear resonator includes a piezoelectric substrate, a first electrode extending from a first end to a central portion of a first surface of the piezoelectric substrate and a second electrode extending from a second end to the central portion of a second surface of the substrate. Thus, the resonator utilizes thickness shear vibrations generated in a portion of the piezoelectric substrate located between the first and second electrodes at the central portion of the substrate. The width W of the la substrate is set to be equal to or less than about 0.7 mm and also to satisfy both of the following expressions (1) and (3) or to satisfy both of the expressions (2) and (3):(1) 0

    摘要: A Colpitts-type oscillation circuit, employing a ceramic resonator vibrating in the energy trapping thickness shear slide mode is disclosed in which, an antiresonance frequency of the ceramic resonator has a negative temperature characteristic which is less step than that of its resonance frequency. Capacitance between terminals of the ceramic resonator is set so that an oscillation frequency (Fosc) of the oscillation circuit at the ordinary temperature is higher than a central frequency ((Fr+Fa)/2) of the ceramic resonator. Thus, it is possible to employ a ceramic resonator having a large bandwidth (.DELTA.F), thereby improving the temperature characteristic of the oscillation frequency.

    摘要: A solution casting apparatus includes a drive roller as a conveying means. The drive roller conveys a polymer film peeled from a belt, the polymer film still containing a solvent. The drive roller has corrugation valleys and corrugation peaks formed on a peripheral surface along a circumferential direction of the drive roller. Each of the corrugation valleys and the corrugation peaks has a substantially semicircular cross section. The corrugation valleys and the corrugation peaks are disposed alternately in an axial direction of the drive roller. A pitch Pv between the corrugation valleys and a pitch Pm between the corrugation peaks are in the range of 0.01 to 2 mm, and a height Hv-m from a lowest point of the corrugation valley to a highest point of the corrugation peak is in the range of 0.01 to 1 mm. A curvature radius Rv of the corrugation valley and a curvature radius Rm of the corrugation peak are in the range of 0.1 to 0.5 mm.

    摘要: A piezoelectric resonator includes two sealing substrates, a seal portion, and an energy-trap type piezoelectric resonance element which is adapted to vibrate in a third harmonic of thickness extensional vibration. The piezoelectric resonance element includes a piezoelectric substrate and a pair of excitation electrodes, which are disposed on opposite major surfaces of the piezoelectric substrate. A portion of the piezoelectric substrate sandwiched by the excitation electrodes defines a vibrating portion. The sealing substrates each have a cavity formed therein and are attached onto the corresponding major surfaces of the piezoelectric substrate such that the cavities define a space for vibration. The seal portion is formed around the vibration space so as to damp leaking vibration. The vibrating portion is arranged such that the approximate center thereof is spaced from the approximate center of the vibration space as viewed along the major surfaces of the piezoelectric resonance element.

    摘要: A composite type piezoelectric component has electrodes formed on both major surfaces of a piezoelectric device. These electrodes are electrically connected and mechanically attached to two terminals having top ends shaped so as to receive and support both ends of the piezoelectric device. A capacitor is constructed with a pair of divided electrodes formed on one major surface of a dielectric substrate and another such pair on the other major surface thereof. The capacitor is attached to the two terminals by joining the divided electrodes on one of the major surfaces of the capacitor to the top ends of the terminals so as to leave a clearance between the capacitor and the piezoelectric device. A third terminal is connected to both of the other pair of divided electrodes. These two pairs of electrodes are substantially equally shaped such that directionality is not critical when the capacitor is attached to the terminals.

    摘要: A method for producing an energy trap piezoelectric resonator which operates in a thickness longitudinal vibration mode and which includes a piezoelectric member and first and second vibrating electrodes disposed on respective major surfaces of the piezoelectric member, involves the use of a piezoelectric material having an R value and an A value which are selected such that Qe=C/(R×A), where R and A are the average pore size in micrometers and the porosity in percent of the piezoelectric member, respectively. Here, Qe is a value at a frequency to be used and C is a constant that is determined by the piezoelectric material of the piezoelectric member. An energy trap, thickness longitudinal piezoelectric resonator produced by this method has a sufficiently high response to a vibration mode to be used, without any limitation on the type of piezoelectric material and size of the piezoelectric member and the frequency to be used.
