Title: Demodulation method and demodulator
Inventor: SOGA SHIGERU
IPC: H04L27/38
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To obtain a correct demodulation signal by estimating timewise fluctuation in a phase caused by a phase error and a frequency error at a high speed in the case of phase synchronization detection by the quasi-synchronization detection system. SOLUTION: An optimum phase estimate circuit 8 estimates an optimum phase compensation amount H based on a received tentative demodulation signal U, a confirmative demodulation signal V and an optimum frequency compensation amount F by taking phase fluctuation due to a frequency error into account. Then a phase fluctuation estimate circuit 9 estimates the optimum frequency compensation amount based on fluctuation of a predetermined period of the optimum phase compensation amount H. A complex multiplier 7 applies complex multiplication to the tentative demodulation signal U and the optimum phase compensation amount H to completely eliminate a phase error due to the frequency error and to obtain a correct demodulation signal V.

Title: Automatic level controlling circuit
Inventor: FUJISAWA MASANORI
IPC: H03G3/30
Filed: 1984-09-11
Abstract: PURPOSE:To set the optimum ALC level, by adjusting the offset voltage of a comparator circuit which compares the output signal level of an amplifier in accordance with a working supply voltage. CONSTITUTION:The output signal level of a sound recording amplifier 8 is compared at a comparator circuit 13. The reference voltage of the comparator circuit 13 is given from a reference voltage generating circuit 16. The offset voltage of the comparator circuit 13 is determined by values of a variable resistor 17 and resistance 24. Therefore, when the value of the resistance 24 is set at a prescribed value and the value of the variable resistor 17 is set in accordance with the working supply voltage, the offset voltage of the comparator circuit 13 can be changed and, as a result, the ALC level can be changed. Accordingly, the optimum ALC level corresponding to the working supply voltage can be set.

Abstract: PURPOSE:To make the phase state of light an equal phase and to provide a beam capable of converging to one beam close to a Gaussian distribution by providing a phase compensation part inside an optical waveguide for the beam propagating through the optical waveguide at a high order waveguide mode. CONSTITUTION:When a basic wave is made incident on a waveguide type wavelength conversion element 2, it propagates through the optical waveguide 3 in a first mode, and it emits from the end surface of the optical waveguide 3 as the beam to be collimated by a collimate lens 1.

Title: Printing device
Inventor: ISOZAKI ATSUSHI
IPC: B65H1/26
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To provide a printing device capable of inhibiting an original from being carried in the case of detecting that recording paper can-not be fed by detecting whether or not the recording paper can be fed before carrying the original. SOLUTION: When a recording paper cover is open (S1: Yes) in the case of depressing a copying start key (S91: Yes), the recording paper housed in a recording paper tray does not abut on a paper feeding roller, so that the recording paper can not be fed even when the paper feeding roller is rotated. Therefore, error processing is executed without carrying the original to the inside of an MFD (S3). Since the original is not carried to the inside of the MFD when the recording paper cover is open, troublesome operation that the original is removed from the inside of the MFD in the case of executing copying processing again is eliminated.

Filed: 1989-07-26
Abstract: PURPOSE:To make the pattern at a weak input electric field stable while preventing the increase in sag at a strong input electric field by providing a correction circuit increasing a charge current to a capacitor at a weak input electric field to average the AGC speed as a whole. CONSTITUTION:An input signal is inputted to an AGC detection circuit via an intermediate frequency amplifier circuit IFA, a detection circuit VD, an amplifier circuit VA and a noise cancelling circuit NC while the gain is controlled with a voltage through the AGC amplifier circuit. A collector current of transistors(TRs) Q1, Q3 of the detection circuit charges a capacitor C via a terminal P1 and its holding voltage VC is delivered to the IFA and an RFAGC. A reference voltage V2 is given from a terminal P3. The operating range of TRs Q5, Q6 is adjusted by a current I2 of a constant current source 12 and a resistor R5 and the AGC response is made flat as a whole from a weak input electric field (VC'<V2) till a strong electric field to apply the correction. Since the VC' is minimized of temperature dependency and power supply dependency by the AGC amplifier circuit, the AGC speed receives less effect of temperature and power fluctuation and the pattern at a weak input electric field is made stable.
