Abstract: PURPOSE:To allow the equalizer to follow fluctuation of a frequency on a transmission line whose transmission signal has plural frequency components by using a compensation signal obtained from a carrier fluctuation prediction signal so as to eliminate a carrier fluctuation signal in an output signal of a transversal filter. CONSTITUTION:A base band signal x(i) resulting from a reception wave subject to quasi-synchronization detection is inputted from an input terminal 17 to a transversal filter 18.

An output y(i) of the filter 18 and a compensation signal are multiplied by a complex number multiplier 25, in which carrier fluctuation components are eliminated. An output of the complex number multiplier 25 is inputted to a discrimination device 19 and its digital signal is outputted from an output terminal 21. An inverse modulator 23 inverse modulates the output y(i) of the filter 18 by using an output signal d(i) of the discrimination device 19 to extract a carrier fluctuation signal z(i). The tap coefficient Wk of the filter 18 and the parameter of the carrier signal prediction device are obtained by the computing element 22 and the carrier fluctuation signal prediction device 24 respectively so as to minimize the evaluation function.

Title: Operating method for system consisting of base station and responder and system proper to the method
Inventor: RITTER SIEGFRIED
IPC: G01S13/79
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To provide the method by which a responder itself surely tunes its resonance frequency to a carrier frequency of a base station automatically and quickly. SOLUTION: In the case of operating a responder 1 coupled with a base station in noncontact without its own energy source, the responder 1 generates a supply voltage to activate circuit devices of the responder 1 from an electromagnetic field sent from the base station. The produced supply voltage depends on how well a resonance circuit (consisting of components 2, 3) of the responder 1 is tuned to the carrier frequency of the base station.  In this case, optimum tuning is conducted by measuring a voltage generated in the coil 2 of the resonance circuit of the responder 1, connecting an auxiliary capacitor 26 to the 1st capacitor 3 of the resonance circuit, detecting a change in the voltage induced in the coil 2 after that, connecting at least one 2nd capacitor 23 in parallel with the 1st capacitor 3 or disconnecting the 2nd capacitor 23 from the capacitor 3 in response to the voltage change.

Title: Printing of daisy wheel printer
Inventor: FUJII NOBUHIKO
IPC: B41J19/18
Filed: 1987-04-16
Abstract: PURPOSE:To enable suitable shadow printing to be executed, by a method wherein a carrier is fed with no load in two way printing, and printing is started again after returning the carrier in the reverse direction by a transfer correction. CONSTITUTION:Before shadow printing is carried out a carrier 6 is moved from an initial position A by a movement that is the sum of transfer a correction N1 and a normal movement N2. That is, it is carried by the transfer correction N1 in excess at a reverse point. This transfer correction N1 means a no-lead feed when printing is not carried out. Then, the carrier 6 is returned by the transfer correction N1 when carried with no load, and driven reversely. Therefore, the carrier 6 is carried by the correction transfer distance N1 in excess, and printing is started again after returning by the distance. By such carrying with no load of the carrier 6, normal shadow printing is executed on the initial character after reversal of the carrier 6.
