Title: Adaptive waveform equalization system
Inventor: MATSUSHIGE HIROMI
IPC: H04B3/04
Filed: 1993-02-01
Abstract: PURPOSE:To prevent the adaptive equalization operation from occurring a malfunction even when a specific pattern is inputted by interrupting the adaptive equalization operation when a continuous pattern where plural pieces of tap coefficients making a waveform distortion a minimum exist is inputted. CONSTITUTION:An output signal waveform-shaped by a waveform equalizer constituted of delay circuits 107, 108, multiplying circuits 109-111 and an adding circuit 112 is distinguished to data '1' or '0' by a data distinguishing circuit 105. On the other hand, an equalizing error signal eK from an equalizing error detection circuit 106 and an input signal X band-limited by passing through a low-pass filter 116 having a (1+D) characteristic are multiplied by a multiplying circuit 119 in tap coefficient updating circuits 113-115. By taking a correlation between the signal eK and the signal X by the multiplying function, a step gain is corrected for the input signal changing time sequentially, and a feed-back rate is reduced for an all '1' data input pattern capable of extracting no characteristic of the input signal because of containing only one frequency component.

Filed: 1990-01-25
Abstract: PURPOSE:To prevent fluctuation of rotational speed of output shaft or lowering of output by arranging means, for expanding/contracting through external power supply and regulating an energizing means, in a casing. CONSTITUTION:When a piezoelectric body 26 is subjected to external pressure and contracted, electromotive force is produced between electrode plates 27 whereas when external voltage is applied between the electrode plates 27, the piezoelectric body 26 expands/contracts vertically. Consequently, the piezoelectric body 26 can be employed as means for regulating the energizing force of a belleville spring 22 and a pressure sensor for detecting the energizing force of the belleville spring 22 against a rotor 6. When the energizing force of the belleville spring 22 is detected based on a detection voltage of the piezoelectric body 26 during stoppage of a motor and a minus voltage is applied onto the piezoelectric body 26 when tbe energizing force exceeds a reference value due to thermal expansion of a resilient body 5 or the like in order to contract the piezoelectric body 26, energizing force of the belleville spring 22 can be lowered.

Abstract: PURPOSE:To achieve the prevention of unauthorized reproduction from soft tapes by making recording of normal signals infeasible in the case of recording special signals in the soft tape and recording reproduction signals with another VTR. CONSTITUTION:The output of a synchronous separator circuit 2 forms the pulses delayed by the period about half that of horizontal synchronizing pulses in a monostable multi 4. A monostable multi 5 is driven by the trailing edge of said pulses to make the pulses of the width about half that of the horizontal synchronizing pulses. The pulses corresponding to equivalent pulse period are made at every other one field in a monostable multi 7 by way of an FF 6 by the output of a perpendicular seprator circuit 3. Further, a monostable multi 8 is driven by the trailing edge of the output of the multi 7 to make the pulses corresponding to the vertical blanking period after the equivalent pulses and at the same time the outputs of the multis 5, 8 are led to an AND 9, the output whereof is then applied to the video signal in an adder 10. This signal is further passed through a frequency modulator 11 and is then recorded in a soft tape. Thereby, recording of normal signals becomes infeasible.
