    Abstract: An article that is particularly well suited for use as a gas turbine engine component has a metallic substrate and a ceramic thermal barrier layer including a mixed metal oxide system comprising a compound selected from the group consisting of (i) a lanthanum aluminate and (ii) a calcium zirconate, the calcium in which is partially replaced by at least one calcium-substitute element, such as strontium (Sr) or barium (Ba). In addition, the lanthanum in the lanthanum aluminate can be partially replaced by a lanthanum-substitute element from the lanthanide group, particularly gadolinium (Gd). A process for producing such an article comprises providing a pre-reacted mixed metal oxide system as described above and applying it to the substrate by plasma spraying or an evaporation coating process.

    Abstract: Reliable phase synchronicity between a local carrier signal and the carrier signal of an amplitude and/or phase shift keyed received signal is produced as quickly as possible by employing a phase detector characteristic whose root means square outside of the synchronization point is as large as possible and whose synchronization point, i.e., zero passage, is situated such that it also considers a phase deviation of the received signal component from its quadrature position.

    Abstract: A demodulator circuit for demodulating an input signal constituted by a modulated carrier. The circuit is provided with a phase control loop composed of a signal mixer having two inputs and an output and providing a signal at its output proportional to the algebraic product of the signals at its inputs, one of the mixer inputs being arranged to receive the demodulator circuit input signal, a voltage controlled oscillator having a control input and an output connected to the other input of the mixer and providing a signal at a frequency varying linearly with the voltage at its control input, and a lowpass filter connected between the mixer output and the oscillator control input. The components of the loop present a set of parameters defining the operation of the loop, which parameters include the peak voltage at the output of the oscillator, the oscillator modulation sensitivity, the voltage amplification factor of the lowpass filter and the gain of the mixer. Circuit devices are connected to the loop for varying at least one of the parameters in inverse proportion to the peak amplitude of the input signal carrier for causing the product of the parameters and the carrier peak amplitude to be substantially constant.
