Title: Variable wavelength demultiplexer
Inventor: ITO TORU
IPC: H04B10/29
Filed: 2000-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a variable wavelength demultiplexer which can control the movement of the wavelength filter even during a momentary interruption of an input optical signal as in the case of the input light signal is present. SOLUTION: The variable wavelength demultiplexer has a wavelength demultiplexing portion which selects a specific wavelength providing a maximum transmittance peak to an output optical signal from the wavelengths of an input optical signal, a wavelength-filter controlling system which outputs a control signal composed of a direct current signal for movement which moves the wavelength filter to a position to select the output optical signal of the specific wavelength according to the wavelength fluctuations of the input optical signal and an alternating current signal for detection which provides the output optical signal with an oscillating frequency by finely vibrating the wavelength filter on a constant detection frequency.  The wavelength-filter controlling system has a wavelength-filter controlling portion which maintains the output of the direct current signal for movement even during a momentary interruption of the input optical signal and which includes a direct-current- component forming portion, which defines the magnitude of the direct current signal for movement based on the amplitude of the output optical signal, and an alternating- current-signal generator for detection which outputs the alternating current signal for detecting with the detection frequency.

Title: Communication device
Inventor: HORIIKE YOSHIO
IPC: H04B1/04
Filed: 2000-09-05
Abstract: PROBLEM TO BE SOLVED: To eliminate fluctuations in the frequency of transmission signals or the frequency of local oscillation signals when signals are transmitted or strong input signals are received in a communication device of maintaining communication by means of radio waves. SOLUTION: This communication system is equipped with a receiving means 30 and a frequency synthesizer 31 for selecting channels. The frequency synthesizer 31 is equipped with a voltage-controlled oscillator(VCO) 10 and a 1/N frequency dividing means 20 which divides the output of the voltage-controlled oscillator 10 into N parts (N is an integer and larger than 1). Signals outputted from the 1/N frequency dividing means 20 are fed as local oscillation signals to the receiving means 30, so that fluctuations are prevented from occurring in the frequency of local oscillation signals even if the receiving means receives target signals of high power.
