Title: Adaptive filter control method
Inventor: KAYANUMA KINJI
IPC: H03H15/00
Filed: 1992-05-28
Abstract: PURPOSE:To reduce a decision error by eliminating an output signal from a reference signal used in coefficient control. CONSTITUTION:A delay element 13 between a subtractor 9 and a switch 11 is provided to generate delay for unit time for an error signal selection circuit 10. Accordingly, the delay quantity of a filter input signal inputted to a correlator 12 can be increased by that time. The switch 11 on the feedback route of an error signal is closed only when both the output of the circuit 10 and that of a synchronizing signal detection circuit 19 become active. The coefficient control is performed only by the error signal which satisfies a condition in a training signal period and also provided at the circuit 10. This method is effective when the waveform distortion of an input signal is large, and the decision error obtained from a reproducing signal is large. The coefficient control is performed only by a training signal. Thereby, it is possible to take out satisfactory equivalent output with low decision error even when large amount of nonlinear distortion exists in an optical disk reproducing waveform inputted to an adaptive filter and to reduce the decision error.

Abstract: PURPOSE:To prevent slant feed of sheets surely by allowing a pressure contact lever mechanism to balance the contact forces transmitted to feed rollers on both sides. CONSTITUTION:When stacked copying sheets 12 of comparatively great size are accommodated in a copying sheet cassette 2 and separable loading on the cassette part is made in an intended manner, a pressure contact lever 18 of a pressure contact lever mechanism 14 is deviated resiliently toward a placing plate 10 through the action of a spring, and then rollers 28a, 28b fitted at the tip of said pressure contact lever 18 will act on the undersurface of the tip of said placing plate 10 through an opening 8 formed in the bottom wall 6 of the cassette body 4. Here a shafting member 26 is capable of swinging oscillatively with a boss 36 as its fulcrum, so that the contact force applied to the placing plate 10 through the riller 28a is balanced to or substantially equal to the contact force applied to the same plate through the other roller 28b. Accordingly the pressures to the uppermost copying sheet given by feed rollers 40a, 40b on both sides are made equal substantially to contribute to sure prevention of slant feed of sheets.

Inventor: SATO YUKINORI
IPC: B41J2/30
Filed: 1984-08-06
Abstract: PURPOSE:To make it possible to make printing pressure constant without increasing the capacity of a driving power source, by changing the driving frequency and lateral feed speed of a printing wire corresponding to the detection value of driving voltage. CONSTITUTION:The driving transistors 25-28 of a stepping motor 24 for laterally feeding printing wires 1-11 are provided while a control circuit 31 for changing the driving cycles of transistors 12-23 and transistors 25-28 by the signal from a detection circuit 30 for detecting the voltage value of a power source 29 is provided. Because the voltage of the power source 29 is sufficiently high at the start time of printing, the control circuit 31 drives the transistors 12-23, 25-28 at a min. cycle. When printing continues and voltage begins to fall, the voltage detection circuit 30 informs this state to the control circuit 31 to prolong the driving cycles of the transistors 12-23, 25-28. Because the driving cycle of esch printing wire and the lateral feed speed thereof are changed by this method, printing pressure can be made constant without increasing the capacity of the driving power source.

Abstract: PURPOSE:To realize binary, one-digit addition at a high speed with the constitution of a small number of transistors(TR) by using an exclusive NOR gate composed of four MOS TRs. CONSTITUTION:The output signal Q of the connection point N of an exclusive NOR gate (EXOR) 24 is A.B+(-A).(-B), where A and B are operands. The sum output S of a sum output terminal 20s is A.(-B)+(-A).B.

Consequently, the output delay of the sum output S when the A and B are both '1' is improved. A carry output C is obtained by inverting the output of the NAND 25 which is supplied with the A and B by a CMOS inverter 23.
