Title: Phase estimate method for demodulator
Inventor: MABUCHI TETSUO
IPC: H04L27/227
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To accurately demodulate a received burst signal received with a small memory capacity and a small circuit scale. SOLUTION: A 90 deg. phase shifter 2 separates a signal from a local oscillator 1 into an in-phase component and a quadrature component. Mixers 3a, 3b multiplies each component with a received IF signal, which results in receiving quasi-synchronization detection. A/D converters 5a, 5b A/D converts the quasi- synchronization detection signal and integration circuit sections 6a, 6b integrates its preamble part. The integrated signal is latched by latch circuits 7a, 7b. A timing circuit 8 controls the latch timing. A power detection section 10 detects the power of the latched signal and a maximum value detection section 11 detects the maximum value of the power, then selectors 12a, 12b obtain a timing when the power is maximized. A phase θ is obtained from the arctangent of the maximum power and it is used for an initial value of a voltage controlled oscillator VCO of a demodulator 13.

Filed: 1989-04-26
Abstract: PURPOSE:To contrive the formation of a fine pattern by providing thin holes for blowing off gas and liquid in a tip part of each capillary of a foreign matter removal brush. CONSTITUTION:As the diameter of each thin hole is extremely smaller than that of the capillary 2 of a brush, an N2 gas 1 blows off in the form of a jet from each thin hole of the capillary.

Filed: 1988-04-28
Abstract: PURPOSE:To remove time required for tracking to an objective track and to attain rapid access by providing the title device with means for detecting the deviations of tracks and respectively detecting the quantity and direction of eccentricity based upon signals generated as the result of detecting the deviations and correcting the eccentricity based upon the detected results.

Abstract: PURPOSE:To rapidly generate a restoring torque even though the idle rotational speed abruptly varies due to disturbance or the like, by detecting a period of a stroke of an engine so as to estimate a torque correcting rate, and by compensating the fuel supply volume and the ignition timing in accordance with the estimated toque correcting rate. CONSTITUTION:During operation of an engine 12, whether an idle switch is turned on or not, and whether an engine rotational speed delivered from a crank angle sensor 50 is between specified upper and lower limits are determined.

Abstract: PURPOSE: To make it possible regardless of shapes of materials to be reeled in or reeling-in speed to control effectively a reeling-in apparatus that is used to reel-in a longer thread, by obtaining a speed feedback signal of a motor through an integrating system wherein a winding diameter signal is made uniform.  
     CONSTITUTION: A signal generator 10 obtains from a position detector 3 a signal proportional to a winding diameter deduced from a relationship of a bobbin 2 and a wound surface A, and multiplies by a multiplier 10a an output of the position detector 3 by an output of a speed command setter 8. An output of the multiplier 10a is inputted to an integrator 10b to be integrated with respect to time, an output of the integrator 10b becomes constant when it reaches the inputted value, and by a subtractor 10c the output of the integrator 10b is subtracted by an output of the speed command setter 8 to issue a winding diameter signal. Thus when by a subtractor 10d an output of the subtractor 10c is subtracted by an output of a speed meter generator 6, an output of the subtractor 1d is issued as a speed feedback signal for reeling-in speed.
