摘要:
The code system is realized by that a plurality of waveforms A and B each having duty ratios of 50% in which only any one of a rising edge and a falling edge is present are combined with each other, and “1” and “0” are allocated to the combined waveform. In accordance with the present invention, both a clock and data can be transmitted at the same time, and can be readily demodulated without using a complex PLL circuit. As a trial manufacture according to the present invention, the demodulator could be realized which could allow variations contained in an input frequency by more than 1 digit under operating voltage of 2 V. The effectiveness of this patent could be confirmed.

A semiconductor integrated circuit device for communication is provided with a PLL circuit or the like formed therein, the PLL circuit which is capable of realizing the compensation of fluctuation due to temperature change, the inhibition of increase in the chip area and the ensurement of the performance margin, and which controls a VCO having multiple oscillation frequency bands. In the case where automatic calibration is performed by switching a switch to a side of a DC voltage source in the PLL circuit using a VCO having multiple oscillation bands, a tuning voltage (Vtune) of an RFVCO is fixed to a voltage value of a DC voltage source. However, since a temperature characteristic of canceling a VCO oscillation frequency is given to the DC voltage source, it is possible to minimize the influence on the band selection when a calibration table comes to no optimum one.

A fuel gas heating control equipment in accordance with the present invention is provided with a gain-determining portion 21 and a time-constant-determining portion 22 which determine values of a gain and a time constant to be used for PI calculations being performed by a PI calculation portion 14. The gain-determining portion 21 specifies a small time constant for the PI calculation portion 14 during load fluctuations when the generator output increases, and specifies a large time constant for the PI calculation portion 14 when the generator output reaches the maximum output. In consequence, during load fluctuations, responsiveness is good and a rapid change in temperature can be followed, so that a fuel gas temperature will not fluctuate in response to a slight change in temperature at the maximum output, thereby achieving a stable fuel gas temperature.

There is provided a power control circuit having a stable high-speed operation, and a semiconductor device and a transceiver circuit using it. The power control circuit controls the gain of an amplifier so that power outputted from the amplifier reaches a desired value according to a digital control signal. The power control circuit includes a digital feedback loop which converts a detected signal obtained by detecting a value of the output power of the amplifier to a digital signal, determines a differential between the digital signal and the digital control signal, converts the differential to an analog signal and outputs a first feedback signal, an analog feedback loop which outputs a high frequency element corresponding to a differential between an analog signal to which the digital control signal is converted and the detected signal, as a second feedback signal, and an adder which determines the sum of the first and the second feedback signal and outputs a gain control signal for controlling the gain of the amplifier.

A turbine plant includes a steam turbine, a gas turbine connected to the steam turbine, a generator, and an analyzing apparatus. The steam turbine includes a high pressure steam turbine, an intermediate pressure steam turbine, and a low pressure steam turbine. The turbine plant is adapted to be driven by a selected one of natural gas and oil. The analyzing apparatus collects estimates of the steam turbine output based on the inlet steam pressure of the intermediate steam turbine with a correction value. The correction value is calculated including the influence of the difference between the gas fuel case and the oil fuel case. The analyzing apparatus estimates a gas turbine output by calculating the difference between the estimated steam turbine output and the total output of the turbine plant. The gas turbine is operated using the estimated gas turbine output.
