摘要： A timing recovering apparatus comprises an equalizer for equalizing a digital data signal subjected to interleaved NRZI such that the digital data signal has partial response (1, 0, -1), two comparators for comparing the equalized data signal with two different reference levels, two phase comparing portions for detecting phase difference between the outputs of the comparators and a reproduced clock signal separately, an adder for summing the outputs of the phase comparators, and a VCO for generating the reproduce clock signal in accordance with the output of the adder. This timing recovering apparatus performs phase comparing with two different phase comparators and PLL control is performed on the sum of the outputs of the two different phase comparators, so that the clock signal is not affected by data pattern of the data signal. An automatic slice apparatus comprises the equalizer for equalizing a digital data signal subjected to interleaved NRZI, and two comparators supplied with reference levels, and the timing recovering apparatus, detects amplitude of the output of the equalizer in response to the reproduced clock signal to compensate the reference levels.

摘要： A monolithic piezoelectric element includes an element assembly in which internal electrode layers and piezoelectric ceramic layers are laminated alternately. The internal electrode layers contain an Ag—Pd alloy, which has an Ag content of 85 percent by weight or more as a primary component, a metal element having a valence of at least one of pentavalence or hexavalence. The piezoelectric ceramic layers contain a composite oxide represented by Pb(Ti,Zr)O3 as a primary component, a part of Ag contained in the internal electrode layers is almost uniformly diffused therein and, the metal element is diffused in the form of a metal oxide in such a way that the concentration is reduced with decreasing proximity to the internal electrode layers. In this manner, a monolithic piezoelectric element having a desired large piezoelectric constant can be obtained without inviting an increase in cost even when a firing treatment is conducted at low temperatures.
