    摘要: An automatic frequency control (AFC) system adapted to compensate for an insufficient capture range is described herein. The AFC system may be implemented in a mobile station for use with a wireless communications system such as code division multiple access (CDMA). The AFC system determines if a transmission frequency is within a capture range. The AFC system modifies a reference frequency generated by the mobile station if the transmission frequency is not within the capture range.

    摘要: A matrix type piezoelectric/electrostrictive device in which a plurality of piezoelectric/electrostrictive elements almost in a pillar shape, each having a piezoelectric/electrostrictive substance and at least a pair of electrodes being formed on the sides of the substance, are vertically provided on a thick ceramic substrate. It is driven by displacement of the piezoelectric/electrostrictive substance. In this device, a plurality of piezoelectric/electrostrictive elements are integrally bonded to the ceramic substrate and independently arranged in two dimensions. The percentage of transgranularly fractured crystal grains on at least the sides of the piezoelectric/electrostrictive substance on which the electrodes are formed is 10% or less. The unit forms a curved surface near a joined section between the substance and the substrate. The present device can show excellent performances such as large displacement at a low voltage with pushing, distorting, moving, striking (impacting), or mixing an object of action and the like.
