摘要： A dielectric filter includes a dielectric ceramic block having the shape of a rectangular prism and including three or more through-holes formed therein in parallel. An inner conductor covers the inner surface of each of the through-holes to form the corresponding resonator. An outer conductor covers a predetermined outer surface of the dielectric ceramic block, excluding the open end surface. Input/output pads are formed on one side surface of the dielectric ceramic block such that the pads face the two end resonators. Each of the through-holes of the end resonators is provided with a counterbore. An auxiliary conductor is disposed on the open end surface to face at least one intermediate resonator between end resonators. The auxiliary conductor at least partially surrounds the intermediate resonator with an insulating gap formed therebetween, and is connected to the outer conductor on the side surface on which the input/output pads are provided. The auxiliary conductor is formed by a conductive material disposed in a concave portion formed in the open end surface and having a pattern corresponding to the pattern of the auxiliary conductor.

摘要： A light deflector comprising a reflective mirror having a specular surface on top. A flexible supporting plate is retained along its periphery and supports the reflective mirror in an oscillatory manner. The reflective mirror is supported on a point from below by way of the flexible supporting plate. A pair of piezoelectric laminates are disposed at locations that on x- and y-axes through the fulcrum intersecting at right angles in a plane and are distant from the fulcrum. The piezoelectric laminates are capable of expansion and contraction in the direction of z-axis upon application of a voltage to the laminates. The reflective mirror is supported on a point from below by the displacing end of each of laminates.

摘要： A stacked type piezoelectric actuator comprises a main stack of a plurality of electrostrictive strain elements stacked one on another. Each strain element comprises a first piezoelectric element plate having a first direction of polarization and a second piezoelectric element plate having a second direction of polarization.
