    摘要： A transmitter having a transmitting phase synchronizing system. To one input of a frequency mixer is applied the output of a phase synchronizing type digital frequency synthesizer, through a first frequency divider. A modulating signal is applied to another input of the frequency mixer. The output from the mixer is connected via a bandpass filter to a phase synchronizing system having in series, along a main route, a phase detector, a lowpass filter, and a voltage controlled oscillator, and thence to an amplifier system. In a feedback route from another outlet of the voltage controlled oscillator to the phase detector is a second fixed frequency divider. The digital frequency synthesizer itself may have a reference oscillator connected in series to a third fixed frequency divider, a second phase detector, a second lowpass filter and a second voltage controlled oscillator, from which a feedback circuit leads back to the phase detector via the first fixed frequency divider and a variable frequency divider.

    摘要： A duplex transmission and reception system wherein a local oscillator of the receiver is dispensed with by using the output of a modulated transmission oscillator, with its modulation cancelled, in lieu of a receiver local oscillator. The transmitter modulation signal is adjusted by appropriate level correction and phase inversion. The modulated output of the transmission oscillator is itself applied to a modulator, where it is modulated by the adjusted modulation signal. This results in substantially cancelling out the modulation component of the transmission oscillator output. This modulation-cancelled signal is supplied to the mixer of a superheterodyne receiver as a local oscillator signal.

    摘要： A plasma etching apparatus includes a process chamber that can be set at a reduced pressure. A lower electrode on which a semiconductor wafer is placed and an upper electrode opposing the lower electrode are disposed in the process chamber. The lower and upper electrodes are connected to RF power supplies, respectively. First and second RF powers, the phases and power ratio of which are separately controlled, can be applied to the upper and lower electrodes. Parameters including the frequencies, power values, and relative phases of the first and second RF powers are selected in order to set the etching characteristics, e.g., an etching rate, the planar uniformity of the etching rate, the etching selectivity ratio and the like to predetermined values. During etching, the first and second RF powers are monitored by separate detectors, and are maintained at initial preset values through a controller.

    摘要： A piezoelectric oscillator is disclosed which falls under the category of an oscillator including a piezoelectric resonator, an amplifier, and a variable-capacitance element. The variable-capacitance element is a MOS construction type capacitance element, one terminal of that is fixed at a V voltage, and the other terminal of that is applied with a control voltage falling within a range whose intermediate value is the V voltage. As a result of this, a piezoelectric oscillator is realized which can vary its frequency over a wide range even without use of a minus power supply.
